five fascinating facts about your enamel, and how our hydroxyapatite toothpaste can strengthen it
When it comes to oral care, healthy enamel isessential.
As the hard, outer surface of your tooth, your enamel serves as a shield for all of the delicate tissues, blood vessels, and nerves that live below it. We could go on and on about its importance (and trust us, we will). But to mix things up a bit, we’re going to talk about its importance in a new way...sharing some little-known, fascinating facts about this substance and how to nurture it through the use of hydroxyapatite.
We’ll dive into everything from enamel hardness to color to evolution, we’re confident you’ll learn something new about this unique substance.
1: your enamel is the strongest substance in your body
Not only is enamel stronger than bone, it’s stronger than steel and iron, too.
According to the Mohs Hardness Scale, enamel earns a hardness ranking of 5. For comparison, diamonds (the hardest substance on Earth), have a hardness ranking of 10.
Now, you might be wondering....why is it so common for enamel to wear down and deteriorate if it’s so strong and hard? Well, you have to remember that your enamel is paper thin (as you’ll see in the next fun fact), and it comes in contact with so many hard substances, acids, and more. On top of that, chewing, chomping, and grinding can also wear down your enamel over time. Did you know that your back teeth can exert up to 200 pounds of force when you bite down?
Because of all the wear and tear your enamel is exposed to on a daily basis, it requires a steady supply of replenishing minerals (hello, hydroxyapatite) to stay strong and healthy. Otherwise, decay will occur.
2: your enamel has an average thickness of 2-3 mm
The thickness of your enamel can vary from tooth to tooth, but it’s around 2-3 mm thick on average. Enamel on your back molars tends to be thicker than the rest. Which is good since these teeth can exert a bigger bite force.
Scientists explain thatenamel thickness is a trait that distinguishes our (human) genes from the genes of our primate relatives. Enamel thickness allows scientists to explore evolutionary trends and gather data surrounding how different diets can affect your enamel health. They’ve found clear differences in enamel thickness among primates who follow different diets. For example, primate species that ate fruits and leaves (herbivores) had the thinnest enamel while omnivores had thicker enamel.
Now, humans (who have years of evolution under our belts and access to enamel-loving oral care products) have the strongest, thickest enamel of all. Maybe it’s just us, but we feel even more grateful for our strong enamel after learning about how long it’s taken for it to evolve to this point!
3: some enamel is naturally whiter or opaque than others
Enamel thickness and translucency can give off different shades of white...and still be perfectly healthy!
Yep, you heard that right. White teeth are not inherently more healthy than yellower teeth. There’s much more to the enamel story! Your dentin (the bone-like tissue that exists just below the enamel) naturally has a yellowish hue. If you have more translucent enamel (which can still be healthy!), your enamel may appear less white than the next person’s enamel.
Of course, over time, bad oral care habits and enamel wear can darken and damage your teeth. But in general, the whiteness of your enamel does not always indicate whether or not it's healthy.
4: enamel contains no living cells
Your enamel is not alive.
This is an important fact because it means that once your enamel is lost, it cannot grow back. That’s why it’s so important to strengthen and fortify itbefore it’s completely lost.
How can you strengthen it on a daily basis? You can use nano-hydroxyapatite (n-Ha) on a daily basis. Our sensitive+whitening nano-hydroxyapatite toothpaste delivers a daily dose of hydroxyapatite to your enamel. The nanoparticles penetrate your enamel, plugging holes, filling grooves, and repairing scratches on a molecular level.
To add to this, we recommend adding a natural, hydroxyapatite mouthwash to your daily oral care routine for an extra burst of minerals. Prevention is your best bet when it comes to oral care. You want to get ahead of enamel damage before it reaches the point of no return (where fillings, veneers, crowns, etc. come into the picture).
5: your enamel is 96% densely-packed minerals, aka hydroxyapatite
To elaborate on our last point, your enamel is 96-98% densely packed with minerals: calcium and phosphorus. When they bond together, these two minerals create the compound known as hydroxyapatite (our favorite hero substance). The remaining 2-4% of your enamel is organic matter that “holds” the minerals together.
So, your enamel is not only thestrongest material in your body, it’s the mostmineral dense,too!
It’s the perfect protective surface for all of the vulnerable tissues, blood vessels, and nerves that exist right below it. This protective surface has taken thousands of years to evolve into what it is today, so why not help it maintain its strength through healthy oral care habits?
One of the best things you can do to maintain healthy enamel is to brush with hydroxyapatite toothpaste to remineralize the hydroxyapatite that already exists in 96-98% of this protective layer.
Our third-party lab tests show that our hydroxyapatite toothpaste outperformed leading competitors, filling holes, scrapes, and scratches in the enamel much more effectively than other sensitive toothpastes on the market. Some users experienced tooth sensitivity relief (a sure sign of strengthened enamel) in as little as two weeks.
If you’re looking for a way to give your enamel some daily love, Davids Sensitive+Whitening Nano-Hydroxyapatite is the perfect product to add to your daily oral care routine.

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.
