Expanding floss transitions from a compressed strand into a cushioned texture when triggered by saliva.
One of the key benefits of expanding floss is that the texturized fibers grow to fill variable interdental gaps, sweeping away buildup.
The soft structure supports sensitive teeth and protects delicate gum tissue from harsh snapping.
Pairing this tool with a premium formula like Davids nano hydroxyapatite toothpaste creates part of an excellent oral wellness routine.
understand the innovation of expanding floss
Upgrading your oral care routine means choosing products that work naturally with your mouth. If you’ve looked at our site and find yourself wondering what expandable floss is, the answer lies in how the material behaves when you actually start using it.
Standard floss stays thin and rigid under high tension, but the multi-fiber strands in expanding floss behave differently. To see what expanding floss does in real time, look at how the physical design works. When the strand slips between your teeth, moisture from your saliva activates the texturized fibers.
The material expands instantly, increasing its surface area to protect your enamel from hard edges. This extra coverage catches plaque that flat strings slide right past, demonstrating exactly what expanding floss does to elevate daily hygiene.
the history and evolution of interdental care
Cleaning between the teeth has a long history. Early humans used basic toothpicks made from wood or bone to clear food debris. The first version of dental floss that we’d recognize now arrived in the nineteenth century when a dentist advised patients to use a thin silk thread to clean tight spaces. For anyone wanting to know more about historical innovations, asking what expandable floss is serves as a great starting point for analyzing modern interdental textiles.
For over a century, simple silk and nylon threads remained largely unchanged. While these traditional strings worked for large food particles, they had obvious functional flaws. Because they were uniform and inflexible, they often slipped right past stubborn plaque. Looking into the engineering of adaptive fibers reveals what expandable floss is designed to correct in modern routines.
expandable floss in recent times
As dental science advanced, experts realized a flat string couldn’t thoroughly clean human teeth. This understanding led to the development of texturized materials. Knowing what expanding floss does helps you build a daily routine that supports a balanced oral microbiome.
Nowadays, consumers want to know exactly how these fibers perform when compared to the stiff options of the past. If you’re trying to understand what expandable floss does for your long-term gum health, it is all about friction reduction and surface area contact.
the benefits of expanding floss
When you look at expanding floss vs. regular options, the major difference is how the textured fibers react to tension and moisture. Standard strings stay completely flat, which can cause them to pull roughly against your gums or slide right past plaque in wider spaces.
For people interested in a holistic approach to health, studying the benefits of expanding floss shows how much more effective and adaptive design can be. One of the advantages of expandable floss is its ability to custom-fit every unique mouth structure without causing irritation. What’s more, the benefits of expanding floss extend directly to daily gum tissue protection by reducing mechanical pressure. When you know how to use expanding dental floss correctly, you find a tool that balances deep cleaning with exceptional comfort.
An expanding strand changes its shape to fill the tiny gaps between your teeth. Switching to the best expanding dental floss is an easy way to embrace wellness every day. If you want a truly deep clean, discovering what expandable floss is can completely change your perspective on oral care.
how to use expanding dental floss
You get the best possible results from flossing when you use expanding floss correctly. Because this material reacts to moisture, a few quick adjustments to your technique will maximize your clean. Mastering the use of expanding dental floss means you never accidentally irritate sensitive gum tissue.
Start by pulling off about 18 inches of the floss. Wrap the ends around your fingers securely, leaving a fresh section in the middle to clean with.
As you guide the strand between your teeth, the proper method for using expanding dental floss requires a soft, back-and-forth motion instead of forcing it down hard against your gums.
Once the strand is comfortably placed between your teeth, saliva naturally causes the fibers to expand.
Curve the cushioned material into a “C” shape around the side of the tooth, guiding it gently under the gumline and moving it up and down to pull away hidden plaque.
Make sure to use a new, dry section of the strand for every gap, so you get a fresh, premium clean across your entire mouth.
choose a better interdental cleaner for a healthy smile
Combining superior-quality products with naturally derived oral care products from Davids lets you care for your smile with absolute confidence. Your flossing tools should meet high standards for safety and transparency.
By keeping your oral care up to date with the latest design advancements, you make sure your routine works hard for you. When patients ask what expandable floss is and what it can do for them, they’re usually looking for a comfortable solution to tight spacing or sensitive roots. Going from a thin strand to a soft, cushion-like texture addresses the common complaint that traditional cleaning strings feel too sharp or aggressive.
Now that you know how to use expanding dental floss, you can make an informed decision for your teeth. Seeing how this expanding fiber safely clears bacteria beneath the gumline can transform your long-term oral health. When you see what expandable floss is at its core – a modern textile upgrade – you can pair it with a science-backed routine that leaves your mouth feeling fresh and healthy every day.

what is lichen planus?
Lichen Planus is an autoimmune condition that can cause inflammation and irritation in the skin, mouth, scalp, nails, esophagus, ears, nose, eyes, and other areas of the body. It typically appears as follows.
Purple/red flat-topped bumps on the affected skin areas
Fine white “lacy” lines that accompany these bumps
Ridging or splitting in the nails
Sores, flakiness, burning, and pain inside the mouth
Pain and difficulty swallowing (if it’s in the esophagus)
Because lichen planus is a chronic condition, symptoms can come and go, reappear regularly, or persist for a long time. While it can be treated with topical creams on your skin, it can be very tricky to treat those symptoms when they appear in your mouth! On that note, let’s dive into the specifics of oral lichen planus.
what is oral lichen planus?
Oral lichen planus (OLP) refers to the condition that specifically affects the mucous membranes in your mouth (your tongue, gums, and inner cheeks). While there are many variations of oral lichen planus, here’s an overview of the two main types.
Reticular OLP shows up as pale white “lacy” patches. This is the most common type of oral lichen planus and typically does not turn into a more serious condition (like oral cancer).
Erosive OLP appears as red open sores that often hurt and burn. This type of oral lichen planus is more likely to lead to mouth cancer, so it’s best to get it checked regularly.
Both of these types of oral lichen planus come with common symptoms, such as:
Small pale bumps that form a “lacy” pattern on your inner cheeks, tongue, or gums
Red open sores inside your mouth
Dry mouth
Burning, bleeding, inflammation, and irritation with brushing
Sore gums
Metallic taste
Decreased ability to taste
Roughness inside the mouth
General pain and burning throughout the day
All of these symptoms can make it difficult to keep up with your daily habits, whether it’s eating, talking, or keeping up with your oral care routine.
oral lichen planus vs thrush
It can be difficult to distinguish between oral lichen planus and other oral conditions such as thrush and “geographic tongue” because they can all cause white patches or lines in the mouth. To help you separate these conditions, here are a few key things to look out for.
Oral thrush is a yeast (fungal) infection in the mouth that appears as “creamy” white patches in the mouth and cracks in the corner of your lips. It’s often accompanied by dry mouth and burning. Unlike lichen planus, oral thrush can be treated with antifungal rinses.
Oral lichen planus is an inflammatory condition (as described above) that appears as “lacy” white patches, streaks, or tiny white dots.
Geographic tongue looks like red patches on the tongue with white “wavy” lines next to the red patches.
We understand it can be hard to spot the differences among these conditions. If you’re experiencing these symptoms, visit your doctor or dentist to identify the cause and course of action (rather than getting lost in photos and online forums). This is especially important if symptoms appear with mouth or lips swelling after sucralose, since swelling should be discussed with a qualified provider.
Now that we’ve covered the symptoms of oral lichen planus, let’s explore some of the causes.
what causes lichen planus?
While experts don’t know the exact cause of lichen planus, they believe it’s caused by:
immune system dysfunction: also known as an autoimmune response, this occurs when your immune system attacks healthy skin (and mucosal tissue)
genetics: does lichen planus run in your family? Certain genetic variations (called HLA alleles) are associated with lichen planus and can be passed down.
stressful triggers: in addition to general stress, allergies and infections can also trigger lichen planus.
medications: medications for blood pressure, diabetes, heart disease, and malaria have all been linked to lichen planus.
hepatitis C: this virus has also been known to trigger lichen planus.
It’s important to note that some people experience allergic reactions to dental materials like metal fillings, which can cause similar symptoms to lichen planus. At the risk of sounding like a broken record, we recommend visiting your doctor or dentist to distinguish between an allergic reaction and oral lichen planus. It can also help to note whether mouth or lips swelling after sucralose happens repeatedly or only with one specific product.
how common is lichen planus?
About 1 in 100 people will experience lichen planus (this includes all types of lichen planus, not just oral lichen planus). It’s more common to see lichen planus in middle-aged adults over 50.
While non-oral lichen planus tends to affect men and women equally, oral lichen planus is 2x more prevalent in women than men! Experts believe this is related to hormonal changes and the fact that women are more likely to experience other medical conditions that predispose them to oral lichen planus. For example, oral lichen planus occurs more often in perimenopausal women than in the rest of the population. Experts believe this is linked to declining estrogen levels.
It’s important to note that lichen planus is not contagious! So you don’t have to worry about getting infected if someone you know has it.
To recap:
About 1 in 100 people will experience lichen planus.
It’s most common in people 50+ years old.
Oral lichen planus is 2x more prevalent in women than men.
Oral lichen planus is most common in perimenopausal women.
Lichen planus and oral lichen planus are not contagious.
Even though oral lichen planus is not contagious, symptoms like mouth or lips swelling after sucralose should still be taken seriously and reviewed with your dental or medical provider.
the challenges of oral lichen planus
In addition to disrupting your everyday habits like eating, talking, and brushing your teeth, oral lichen planus can evolve and lead to things like:
stress, anxiety, and depression: the pain and discomfort of oral lichen planus can lead to emotional distress, decreased quality of life, and avoidance of social situations. This can lead to more isolation and feelings of hopelessness.
scarring: chronic inflammation can cause permanent tissue damage, leading to stiff, tight oral tissues that affect speech and chewing.
serious pain: severe flare-ups can result in burning sensations, ulcerations, and extreme sensitivity to spicy or acidic foods.
weight loss: pain while eating may lead to reduced appetite, difficulty chewing, and unintentional weight loss.
mouth cancer: in rare cases, oral lichen planus can increase the risk of certain oral cancers.
If someone you love deals with oral lichen planus, we hope this information inspires you to find new ways to support them. To help, we’ve included a few natural ways to manage oral lichen planus below.
People who search for gum disease lichen planus may be trying to understand whether gum soreness is part of a larger oral health concern.
tips to manage lichen planus naturally
prioritize stress management
What’s something you can do every day to check in with yourself and get a break from the demands of your busy life? Whether it’s a three-minute stretching routine, a mindful meditation, a quick walk around the block, a yoga class, or a therapy session, schedule in time to focus on yourself and avoid an overload of stress.
avoid dietary triggers
If you’re experiencing a flare-up of oral lichen planus, it’s natural to want to avoid spicy, acidic, and other irritating foods. While some dietary triggers may be obvious, some less obvious ones include alcohol, tomato-based products, cinnamon, certain sweeteners, peppermint or citrus teas, carbonated beverages, processed meats, and dairy products.
If you notice a pattern after certain foods or drinks, jot it down and bring it to your dentist or doctor so they can help you separate personal triggers from broader dietary restrictions. For example, if you notice mouth or lips swelling after sucralose, that detail may help your provider understand what happened before the flare-up.
utilize anti-inflammatory products and supplements carefully
Try different methods like rinsing with aloe vera juice, applying honey or coconut oil, or using chamomile tea as a mouth rinse. Supplements like turmeric, omega-3 fatty acids, and vitamin D may also help reduce inflammation and support your immune health. As always, we recommend chatting with your doctor before starting new supplements, especially if you’re dealing with a condition like oral lichen planus.
practice good oral hygiene with gentle toothpaste, like Davids
With oral lichen planus, it’s so important to keep your mouth clean. But the condition can make it difficult to tolerate oral care products. This can put you in a bit of a pickle, but that’s where we come in. At Davids, we have a full line of gentle oral care products.
With flavors like mild mint, orange vanilla, and strawberry watermelon, you can choose from a lineup of gentle toothpaste flavors that won’t aggravate your symptoms like strong mint flavors might (more on that below). Or use our new unflavored toothpaste for the mildest brushing experience possible.
In addition to using gentle toothpaste, here are a few daily tips for oral lichen planus:
Avoid alcohol-based mouthwash. Alcohol can irritate and dehydrate sensitive oral tissues, making symptoms worse. Opt for an alcohol-free, soothing mouth rinse like our Davids Hydroxi™ fresh breath mouthwash.
Use a soft-bristled toothbrush. Harsh bristles can aggravate oral lichen planus, so choose a soft toothbrush to gently clean your teeth, like our bamboo toothbrush. It’s made with high-performance, BPA-free bristles derived from plant oil.
Keep your mouth hydrated. Hydration is key to preventing dry mouth, which can worsen symptoms. Drink plenty of water and incorporate saliva-promoting foods like cucumbers, watermelon, and sugar-free gum with xylitol.
Avoid alcohol and smoking. Both alcohol and tobacco can increase dry mouth, irritation, and inflammation, potentially worsening oral lichen planus symptoms.
See your dentist every six months. Regular dental check-ups ensure your condition is monitored, managed, and properly treated with professional guidance. Your dentist can provide personalized care to help keep your mouth as healthy and comfortable as possible. If symptoms change suddenly, become more painful, or do not respond to your current routine, schedule an earlier visit instead of waiting for your next cleaning.
People comparing options for mouthwash for oral lichen planus often look for alcohol-free formulas that feel gentle in a sensitive mouth.
Now, let’s dive into a few reasons why our mint toothpaste flavors can be game-changers for those with sensitive mouths and conditions like oral lichen planus.
why our gentle toothpaste is can be helpful for lichen planus
It’s no secret that the mouth is a uniquely vulnerable area. It contains ultra-sensitive tissue and carries out so many daily tasks from chewing to chatting. Not only can oral lichen planus force you to avoid certain foods, but it also makes it unbearable to use certain oral care products, especially conventional ones that contain sulfates, strong minty flavors, and other irritating ingredients.
As an oral care brand with a mission to help you nurture a “healthy mouth + healthy you,” we’re here to provide you with natural products to help manage and soothe conditions like oral lichen planus. To start, you can trust that our gentle xylitol toothpaste formulas contain:
saliva-stimulating ingredients: dry mouth can worsen symptoms of oral lichen planus, so we incorporate naturally hydrating ingredients like xylitol, coconut oil, and vegetable glycerin to help support saliva production and keep your mouth comfortable.
mild, mouthwatering flavors: Our toothpaste is flavored with gentle, naturally derived ingredients like coconut, vanilla, mild fruit extracts, and (low concentrations of) premium mint essential oils to provide a refreshing but non-irritating experience.
zero sulfates (including SLS): our formulas are completely free of harsh foaming agents like sodium lauryl sulfate (SLS), which can irritate sensitive oral tissues and worsen lichen planus symptoms. In place of SLS, we use sodium cocoyl glutamate, which is derived from coconut material. It creates a gentle, mild foaming action to aid in the cleaning and whitening process without irritating your mouth.
zero artificial colors, flavors, or harsh preservatives: we believe in keeping things simple, natural, and effective.
With our thoughtfully crafted formulas, you don’t have to choose between effective oral care and gentle ingredients. We’re here to help you maintain a clean, healthy mouth without unnecessary discomfort. Because when your oral care works with your body, not against it, you can smile, speak, and enjoy life with more comfort and confidence.
oral lichen planus FAQs
what toothpaste is best for oral lichen planus?
A gentle toothpaste that is free from SLS, harsh foaming agents, artificial flavors, and overpowering mint can be a better fit for sensitive mouths. Many people with oral lichen planus prefer mild flavors and formulas designed to clean effectively without extra irritation.
is oral lichen planus contagious?
No. Oral lichen planus is not contagious, so it cannot be passed from one person to another through kissing, sharing food, or close contact.
should I see a dentist for oral lichen planus?
Yes. A dentist, doctor, or oral medicine specialist can help confirm what is causing your symptoms, monitor changes, and recommend the right treatment plan. Regular checkups are especially important if you have erosive symptoms, open sores, or persistent pain.
can oral lichen planus go away?
Oral lichen planus is usually considered chronic, which means symptoms may come and go over time. While there is no one-size-fits-all cure, a gentle oral care routine, trigger management, and professional guidance can help many people manage discomfort.

key takeaways
Toothpaste traditions from Japan, Asia, India, and the Middle East have shaped global toothpaste trends and alternative formulas.
Nano hydroxyapatite, developed commercially in Japan, is becoming a common toothpaste ingredient due to its biocompatible, enamel-strengthening properties.
Davids draws on global ingredient traditions to offer fluoride free, SLS free, naturally derived toothpaste made in the USA.
Toothpaste is deeply influenced and rooted in global cultures. From vast regional variations in flavors to consumer preferences to texture, the world experiences toothpaste and brushing in surprisingly unique ways.
Despite these cultural differences, almost all modern toothpastes share a core functional blueprint of ingredients that work in tandem to accomplish different outcomes, including:
Abrasives like calcium carbonate or hydrated silica
Surfactants like sodium lauryl sulfate (SLS) or sodium cocoyl glutamate (SCG)
Humectants like glycerin or sorbitol, and
Remineralizers like nano hydroxyapatite
Every country and culture contributes to how toothpaste evolves, diversifying the industry more than the American store shelf would let us believe. Elsewhere, what is considered “alternative toothpaste” in the U.S. is everyday dental hygiene. This blog explores the reasons for rethinking “biomimetic toothpaste” formulas and how various cultures have motivated such change.
why the world is rethinking toothpaste
The interest in global toothpaste trends likely stems from a shift toward conscious oral care and digital connectivity. People are more interested in the products they consume, how they affect their health, and what impact they have on the environment.
Brands are recognizing a measurable shift in clean-label demand, meaning consumers want premium ingredients that are recognizable, ethically sourced, and often plant-derived. They want transparency and to know how and why products use ingredients, as well as where they come from.
Beyond growing interest in clean products, social media and digital access are opening the door to cultural visibility. People can share centuries-old dental traditions instantly on platforms like YouTube, TikTok, and Facebook.
There’s also a growing curiosity about what Western formulas may be missing compared to biomimetic toothpaste and oral hygiene trends globally. For example, harsh foaming agents were the go-to for surfactant ingredients, but research is pointing to adverse oral health effects, such as irritation and sores.
Exploring the traditions and ingenuity of other cultures is how societies and science evolve. By assessing popular ingredients from other parts of the world and their effectiveness, brands can make better products, and consumers can have more choice in the marketplace.
what Japanese toothpaste gets right
Industry professionals often associate Japan with Japanese nano hydroxyapatite toothpaste, and they’re correct to do so. While NASA began research that led to the development of nano hydroxyapatite in 1970, it was Shuji Sakuma who recognized the compound's immense potential. In 1980, Sakuma’s company, Sangi Co., Ltd., launched the first hydroxyapatite toothpaste, a breakthrough for global toothpaste brands.
Focusing on the nano hydroxyapatite ingredient, this variety of toothpaste refreshingly helps fill micro-fissures, promote sub-surface remineralization, and reduce plaque. Because of its chemical makeup, similar to the naturally occurring hydroxyapatite in the body, specifically tooth enamel, the ingredient is biocompatible and gentle, meaning it is safe to swallow.
Japan’s approach to oral health centers on biomimetic engineering and consistent daily rituals. It excels by treating dental hygiene as an advanced branch of skincare and preventative wellness, but it's not the only country making breakthroughs in oral care.
how Asian toothpaste traditions differ from Western dental care practices
While Japanese hydroxyapatite toothpaste made significant strides in oral hygiene, other Asian cultures took a more holistic approach to oral care. These societies focused more on well-balanced, botanical medleys, softer textures, and a more varied flavor profile.
Long before it was a Western beauty trend, East and South Asia used charcoal as a natural abrasive and deodorizer in toothpastes. Today, many companies brand activated charcoal as a whitening agent, one that absorbs impurities and neutralizes volatile sulfur compounds without stripping away moisture.
Biomimetic toothpaste options in Japan, South Korea, and China also favor lighter foaming agents that allow for fast rinsing. The products typically contain gentler surfactants, like SCG, to protect the oral mucosa. It’s also common to find flavor varieties in global toothpaste, like white peach and cherry blossom or green tea and matcha.
Western consumers often favor mint profiles with heavy-foaming action. They associate the tingling sensation of menthol and the foaming with cleanliness, despite the sensation being largely cosmetic. Still, modern consumers are beginning to come around to brands offering formulas with Asian roots because of their performance and increased transparency.
what India’s Ayurvedic toothpaste traditions reveal
While hydroxyapatite is becoming a common toothpaste ingredient, the resilience of traditional ingredients, such as charcoal, in toothpaste demonstrates the quality and usability of naturally derived ingredients. Modern biomimetic toothpaste can combine traditional ingredients with biocompatible, engineered ingredients to improve oral care.
India represents a perfect blend of tradition and advancement. Ayurveda is a 5,000-year-old system of traditional medicine that predates most toothpastes. Ayurvedic toothpastes treat the mouth as an ecosystem, with a goal of tissue preservation, gum health, and balancing the oral environment.
In contrast to Japanese hydroxyapatite toothpaste and most Western toothpastes, Ayurvedic toothpaste doesn’t rely on synthetic compounds. It focuses on natural resources, such as neem and herbal pastes containing clove oil, turmeric, and licorice root. These ingredients have been shown to possess antibacterial properties.
Many global biomimetic toothpastes are combining more traditional Ayurvedic traditions with modern oral care advancements to create hygienic and palatable products. Still, the persevering traditions of India prove that naturally derived oral care is possible and prevalent.
how Middle Eastern toothpaste traditions shaped modern oral care
In the Middle East, oral hygiene has a deep connection to religious practice, particularly Islamic tradition, which recommends using miswak, a root or branch of the Arak tree, as a toothbrush. Simply put, miswak is used as a chewing stick with beneficial compounds. It is a historical and biological predecessor to modern abrasive ingredients, such as hydrated silica.
The prevalence of the root or twig in Middle Eastern cultures now extends beyond these borders. Many contemporary biomimetic toothpaste brands use miswak extract, further supporting the ingredient’s effectiveness while providing a refreshing yet traditional flavor.
why Davids combines traditional techniques and modern sciences
Davids doesn’t shy away from tradition or innovation. It's a brand built on ingredient transparency and global ingredient traditions. In line with the ingenuity of Japanese dental experts and researchers, we rely on nano hydroxyapatite and, for some formulas, activated charcoal. Similar to Ayurvedic traditions, the products are naturally sourced and derived in ways that support more holistic oral care.
Davids took note of what the world was doing to develop an effective, clean formula that’s fluoride free, SLS free, and gentle on teeth. Shop Davids and choose ingredients the world trusts.
Hydroxyapatite is generating a wave of interest in the world of oral care, and rightfully so. But naturally, this interest comes with a lot of questions. Is hydroxyapatite safe? Does it really work? How do I know which product is the right fit?
We completely understand and appreciate the curiosity. After all, nano hydroxyapatite is still new to many people. To address some of your questions and ease some of your doubts, we're answering these questions head on and citing scientific studies along the way.
key takeaways
what is nano hydroxyapatite? It is a nano sized form of hydroxyapatite, the same mineral that makes up about 97% of natural enamel.
Davids uses rod shaped nano hydroxyapatite particles in Hydroxi™ formulas to help bind to enamel and support remineralization.
is hydroxyapatite safe? Hydroxyapatite is biocompatible and already found naturally in teeth and bones.
what is nano hydroxyapatite toothpaste? It is toothpaste made with nano hydroxyapatite to support enamel health, sensitive teeth, and a smoother tooth surface.
is hydroxyapatite safe?
The short answer to this question is yes. Hydroxyapatite itself is a biocompatible mineral that already exists naturally in your body. In fact, it makes up roughly 97% of your tooth's outer surface.
Hydroxyapatite toothpaste can be a good fit when formulated intentionally and carefully. When we say that the safety of hydroxyapatite toothpaste depends on its formulation, we mean several things.
So what is nano hydroxyapatite compared with other forms of the same material? Nano hydroxyapatite particles are small enough to interact with the tooth surface and help support enamel health. Davids uses rod shaped nano hydroxyapatite particles in Hydroxi™ formulas to support remineralization and sensitive teeth.
Diligent user and lab testing matters. How can you evaluate toothpaste without lab testing? Davids submitted samples of top competing sensitive toothpastes to one of the largest third party laboratories that specialize in oral care product testing. Davids performed strongly by helping fill exposed dentin tubules to support sensitive teeth.
The other ingredients in the toothpaste matter. Hydroxyapatite is an important ingredient, but the rest of the formula matters too. At Davids, we use premium ingredients in our formula that took over 4 years to perfect.
does the % of hydroxyapatite in hydroxyapatite toothpaste matter?
The short answer is that it's not that simple.
You'll find that some functional dentists recommend looking for hydroxyapatite toothpaste with "at least X% of hydroxyapatite" in the formula.
But the truth is, the performance of hydroxyapatite toothpaste depends more on quality than quantity of the hero ingredient. It also depends on the type and grade of material being used, the particle shape, the supporting ingredients, and the full formula.
While some competitors use cheaply sourced, less consistent versions of nano hydroxyapatite, Davids only uses nanoXIM from Fluidinova. nanoXIM is widely regarded as the gold standard in nHA with the most scientific research, reviews, and regulatory approvals. It is the most effective, efficient, consistent, and safest ingredient you can use.
what percentage of Davids Sensitive+Whitening Nano Hydroxyapatite Toothpaste is actually nano hydroxyapatite?
We do not disclose % as this is proprietary information to our formulation, and it does not provide meaningful info on how the toothpaste actually performs. The third party lab testing we did shows that Davids performed strongly by helping fill exposed dentin tubules to support sensitive teeth. Please visit our website to see photos as part of our lab results that show the performance of our formulation.
If you are asking what is nano hydroxyapatite toothpaste, the full answer goes beyond a single percentage. It is a toothpaste formula that uses nano hydroxyapatite as part of a broader ingredient system designed to clean, polish, and support enamel health.
what's the difference between hydroxyapatite, nano hydroxyapatite, and micro hydroxyapatite?
Hydroxyapatite is the name of the mineral itself, and for those interested, its chemical formula is Ca10(PO4)6(OH)2. Hydroxyapatite makes up roughly 97% of your enamel, and hydroxyapatite like compounds make up roughly 65% of your bones.
what is nano hydroxyapatite in simple terms? Nano hydroxyapatite is hydroxyapatite with very small particle sizes. Scientific studies suggest that these nanoparticles can bind to the proteins in your saliva and, in turn, the surface of your enamel. This allows nano hydroxyapatite to help strengthen enamel, support remineralization, and help fill exposed dentin tubules.
Micro hydroxyapatite particles are much larger than nano hydroxyapatite particles. They may not interact with the tooth surface in the same way because of their larger particle size.
While nano hydroxyapatite is often preferred in toothpaste formulas, Dr. B of Ask the Dentist confirms that there are no safety concerns regarding the absorption of particles based on size. In other words, both micro and nanoparticles can be absorbed by your cells, which is not an issue because hydroxyapatite is biocompatible.
For more information, we recommend listening to his podcast episode, "Does Size Matter?"
how long does it take for hydroxyapatite toothpaste to support sensitive teeth?
The podcast in the previous section reveals that nano hydroxyapatite toothpaste is an increasingly popular option for sensitive teeth and can provide noticeable support after 2 to 4 weeks of regular use.
Our third party lab testing revealed that our unique formula was effective in bonding to enamel and helping fill exposed dentin tubules to support sensitive teeth after just five days of twice daily brushing.
can hydroxyapatite help reverse cavities?
No toothpaste can claim to reverse cavities or prevent new ones from forming unless that claim is specifically supported and appropriate for the product. Hydroxyapatite can support enamel health, support remineralization, and help strengthen existing enamel as part of a consistent brushing routine.
Check out this article with studies compiled by Mark Burhenne, DDS of Ask the Dentist and Jacqueline Carcaramo, RDH. Many of the studies discuss hydroxyapatite and its role in supporting enamel health.
how do I know which hydroxyapatite toothpaste is right for me?
We may be biased, but our third party lab testing results are not.
We submitted samples of top competing sensitive toothpastes to one of the largest and most trusted third party laboratories that specialize in oral care product testing to see how well Davids Sensitive+Whitening Nano Hydroxyapatite toothpaste would perform.
All numerical and photo evidence from the lab results showed that Davids performed strongly by helping fill exposed dentin tubules and supporting sensitive teeth. In other words, science helps us feel confident in Davids Hydroxi™ formula.
Competing products include Apagard Premio, Boka, Colgate Sensitive, Risewell, Sensodyne Pronamel, and Toms Sensitive.
We also use nanoXIM from Fluidinova, which is the industry leader and the gold standard in nano hydroxyapatite with more scientific research, data, and review than any other ingredient.
how can I use hydroxyapatite best in my oral care routine?
Here are a few tips:
Brush at least twice daily with Davids Sensitive+Whitening Nano Hydroxyapatite Toothpaste.
