Bentonite clay, a naturally occurring substance formed from volcanic ash, has gained considerable traction in the health and wellness community. Promoted for its detoxification properties and mineral content, it’s now being touted as a potential aid for dental health, specifically for remineralizing teeth. But does bentonite clay truly live up to the hype when it comes to restoring enamel? Let’s delve into the science, explore the claims, and separate fact from fiction.
Understanding Tooth Remineralization and Demineralization
Before exploring bentonite clay’s role, it’s crucial to understand the fundamental processes of tooth remineralization and demineralization. Our teeth are constantly subjected to an environment where these opposing forces are at play.
Demineralization occurs when acids, produced by bacteria in the mouth from sugars and carbohydrates, attack the tooth enamel. Enamel is primarily composed of hydroxyapatite, a mineral that provides strength and protection. This acid erosion leads to a loss of minerals like calcium and phosphate, weakening the enamel and potentially leading to cavities.
Remineralization, conversely, is the natural process by which minerals are redeposited onto the enamel, strengthening it and reversing early stages of decay. Saliva plays a crucial role in this process, acting as a buffer against acids and providing the necessary minerals. Fluoride, often added to toothpaste and water, significantly enhances remineralization by forming fluorapatite, a more acid-resistant mineral.
Bentonite Clay: Composition and Potential Benefits
Bentonite clay is composed of various minerals, including calcium, magnesium, silica, iron, and potassium. It’s known for its ability to absorb toxins and impurities, a property attributed to its highly porous structure and negative electrical charge. This negative charge attracts positively charged toxins, binding them and facilitating their removal from the body.
The potential benefits of bentonite clay stem from its mineral composition and absorbent properties. Advocates suggest that its mineral content can contribute to tooth remineralization, while its ability to absorb toxins can create a healthier oral environment. The clay is available in various forms including powders, pastes and as an ingredient in some toothpastes and mouthwashes.
Mineral Content and Bioavailability
The argument for bentonite clay’s remineralization potential rests on its mineral composition. The presence of calcium, magnesium, and other minerals necessary for enamel formation is indeed a compelling factor. However, the key question is whether these minerals are bioavailable – meaning, can they be effectively absorbed and utilized by the body, specifically the tooth enamel?
Current scientific evidence on the bioavailability of minerals from bentonite clay for tooth remineralization is limited. While the clay contains these minerals, their presence alone doesn’t guarantee their successful integration into the enamel structure. Factors such as particle size, pH levels in the mouth, and the presence of other substances can influence mineral absorption.
Detoxification and Oral Health
Bentonite clay’s absorbent properties can potentially contribute to improved oral health by removing bacteria, toxins, and other impurities from the mouth. A cleaner oral environment reduces the acid attacks on enamel, indirectly supporting remineralization by minimizing demineralization.
However, it’s important to note that bentonite clay isn’t a substitute for regular brushing, flossing, and professional dental cleanings. These practices remain the cornerstone of maintaining good oral hygiene and preventing dental problems. The impact of bentonite clay on the oral microbiome and the reduction of specific harmful bacteria needs more research.
Scientific Evidence: What Does the Research Say?
The existing body of scientific research specifically examining bentonite clay’s impact on tooth remineralization is relatively small. While some in-vitro (laboratory) studies have shown promising results, demonstrating that bentonite clay can contribute to mineral deposition on enamel surfaces, more robust clinical trials involving human subjects are needed to confirm these findings.
In-vitro studies provide a controlled environment to assess the direct effects of bentonite clay on enamel. However, the oral environment is far more complex, with saliva, bacteria, and dietary factors all playing a role. Therefore, in-vitro results cannot be directly translated to real-world outcomes.
Well-designed clinical trials are necessary to evaluate the effectiveness of bentonite clay in promoting tooth remineralization in humans. These trials should compare bentonite clay-based products with control groups using conventional remineralization methods, such as fluoride toothpaste. They should also consider factors like age, oral hygiene habits, and dietary habits of the participants.
Potential Risks and Considerations
While bentonite clay is generally considered safe for external use, it’s important to be aware of potential risks associated with oral consumption or use in dental products.
- Contamination: Bentonite clay can sometimes be contaminated with heavy metals, such as lead and arsenic. It’s crucial to choose reputable brands that test their products for purity and ensure they meet safety standards.
- Abrasiveness: Some bentonite clay formulations can be abrasive, potentially damaging the tooth enamel if used too vigorously or frequently. It’s important to use a soft-bristled toothbrush and gentle brushing techniques.
- Interactions with Medications: Bentonite clay’s absorbent properties can interfere with the absorption of certain medications. It’s essential to consult with a healthcare professional before using bentonite clay if you are taking any medications.
- Fluoride Interference: The use of bentonite clay might interfere with the action of fluoride. Further studies are needed to understand if bentonite clay limits the absorption of fluoride used in oral hygiene.
How to Use Bentonite Clay for Oral Health (If You Choose To)
If you decide to incorporate bentonite clay into your oral hygiene routine, here are some guidelines to consider:
- Choose a Reputable Brand: Opt for a high-quality bentonite clay from a trusted source that tests for purity and heavy metal contamination.
- Start Slowly: Begin with small amounts and gradually increase frequency as tolerated.

- Use as a Toothpaste: Some commercially available toothpastes contain bentonite clay. You can also make your own by mixing bentonite clay powder with water, coconut oil, and essential oils for flavor.
- Monitor for Sensitivity: If you experience any tooth sensitivity or gum irritation, discontinue use.
- Consult with Your Dentist: It’s always best to consult with your dentist before making significant changes to your oral hygiene routine, including the use of bentonite clay.
- Continue Regular Oral Hygiene: Do not replace brushing, flossing, and dental visits with bentonite clay use.
The Bottom Line: A Promising Adjunct, Not a Replacement
While bentonite clay possesses properties that could potentially contribute to tooth remineralization and improved oral health, it’s not a magic bullet. The scientific evidence supporting its effectiveness is still limited, and further research is needed to confirm its benefits and safety.
Bentonite clay should be viewed as a potential adjunct to a comprehensive oral hygiene routine, not a replacement for established practices like brushing, flossing, and professional dental care. If you’re considering using bentonite clay for your teeth, it’s essential to do your research, choose a reputable product, and consult with your dentist.
Ultimately, maintaining good oral health requires a multifaceted approach that includes a balanced diet, proper oral hygiene practices, and regular dental checkups. Bentonite clay may offer some additional benefits, but it should be used cautiously and with realistic expectations. Focus on fluoride toothpaste, proper brushing, and regular dental visits as the cornerstones of your tooth remineralization strategy. More research is necessary to fully understand the efficacy of bentonite clay for remineralizing teeth.
Does Bentonite Clay Directly Remineralize Teeth Enamel?
Bentonite clay, while touted for numerous health benefits, doesn’t directly remineralize tooth enamel in the same way fluoride does. Fluoride ions integrate into the enamel crystal structure, forming fluorapatite, a more acid-resistant mineral that repairs and strengthens the enamel. Bentonite clay lacks the specific chemical composition needed to participate in this direct enamel restructuring process.
However, Bentonite clay indirectly supports remineralization by creating a more alkaline oral environment. This alkalinity reduces the acidity that demineralizes teeth. Additionally, it can help to absorb harmful bacteria and toxins in the mouth, reducing the production of acids that erode enamel. By promoting a healthier oral microbiome and reducing acid exposure, bentonite clay contributes to an environment more conducive to natural remineralization.
How Does Bentonite Clay Help With Oral Health if it Doesn’t Directly Remineralize?
Bentonite clay boasts several properties that contribute to improved oral health, indirectly supporting remineralization. Its high absorptive capacity allows it to bind to and remove bacteria, viruses, and toxins from the mouth. This reduces the overall bacterial load and minimizes the acid production that leads to enamel erosion.
Furthermore, bentonite clay is alkaline. It helps to neutralize acids in the mouth and raise the pH level, creating an environment where remineralization can occur more effectively. While it doesn’t supply the minerals to rebuild enamel directly, it helps create the ideal conditions for minerals naturally present in saliva to redeposit onto teeth.
What are the Benefits of Using Bentonite Clay for Teeth?
The benefits of using bentonite clay for teeth primarily revolve around its cleansing and detoxifying properties. It acts as a gentle abrasive, helping to remove surface stains and plaque buildup, leading to a brighter smile. The clay’s ability to bind to toxins and bacteria helps freshen breath and reduce the risk of gum disease.
Beyond its cleaning capabilities, bentonite clay aids in mineral absorption by removing substances that hinder it. This, coupled with its pH-balancing effect, creates a healthier oral environment where the body’s natural remineralization processes can thrive. Regular use can contribute to overall oral hygiene and potentially lessen the need for harsh chemical treatments.
Is Bentonite Clay a Substitute for Fluoride Toothpaste?
No, bentonite clay is not a substitute for fluoride toothpaste, especially for individuals at high risk of cavities. Fluoride is scientifically proven to directly remineralize tooth enamel, offering a significant protective effect against decay. Bentonite clay primarily works by cleansing and creating a more favorable oral environment, not by directly rebuilding enamel.
While bentonite clay can be a beneficial addition to an oral hygiene routine, particularly for its cleansing and pH-balancing effects, it should not replace the proven remineralizing power of fluoride, especially in high-risk cases. It is best used as a complementary therapy, alongside other evidence-based strategies like fluoride toothpaste and regular dental check-ups.
How Can I Use Bentonite Clay for My Teeth?
Using bentonite clay for your teeth is relatively simple. You can create a simple tooth powder by mixing bentonite clay with water to form a paste. Alternatively, you can purchase pre-made bentonite clay toothpaste or mouthwash. When using a homemade paste, apply it to your toothbrush and gently brush your teeth for about two minutes, similar to regular toothpaste.
After brushing with bentonite clay, rinse your mouth thoroughly with water. It’s important to avoid swallowing the clay, as it’s intended for topical use. You can incorporate bentonite clay into your routine 1-2 times per day. Consider alternating between bentonite clay and fluoride toothpaste to maximize the benefits of both.
Are There Any Risks Associated With Using Bentonite Clay on Teeth?
Generally, bentonite clay is considered safe for topical use in the mouth, but potential risks do exist. Abrasiveness is a concern; excessive or vigorous brushing with bentonite clay could potentially wear down tooth enamel over time. It’s crucial to use a soft-bristled brush and gentle circular motions to minimize this risk.
Additionally, some individuals may experience mild sensitivity or irritation. While rare, allergic reactions are possible. It’s always advisable to test a small amount of bentonite clay first to check for any adverse reactions. As with any oral health product, consult with your dentist before making significant changes to your routine, particularly if you have existing dental conditions.
Can Bentonite Clay Help With Sensitivity?
Bentonite clay may help alleviate some tooth sensitivity by reducing inflammation and promoting a healthier oral environment. If sensitivity is caused by gum inflammation or minor surface irritations, the clay’s ability to bind to irritants and reduce inflammation can provide some relief. The clay’s alkaline nature can also help to neutralize acids that exacerbate sensitivity.
However, bentonite clay won’t directly repair severely damaged enamel or address underlying issues like deep cavities or exposed tooth roots, which are often the primary causes of significant sensitivity. In these cases, professional dental treatment is necessary. Bentonite clay can be a helpful adjunct for managing mild sensitivity, but it’s not a substitute for addressing the root cause of the problem.
