Bentonite clay, a natural substance formed from volcanic ash, is increasingly used as a component in natural oral hygiene routines. This fine, earthy powder becomes a potent cleansing agent when mixed with water. The clay is often used as a substitute for conventional toothpaste or incorporated as a specialized rinse. Understanding the properties of this clay and the proper methods for preparation and application allows for its effective and safe use.
Why Bentonite Clay is Used for Oral Health
The primary rationale for using bentonite clay in the mouth lies in its unique electrochemical properties when hydrated. Once mixed with liquid, the clay develops a strong negative electrical charge, which is the mechanism for its cleansing action. This negative charge allows the clay to attract and bind to positively charged ions, such as toxins, heavy metals, and various impurities found in the mouth. This process, known as adsorption, essentially traps these unwanted particles within the clay’s structure, preventing their accumulation.
The clay also contributes to a healthier oral environment by helping to balance the mouth’s pH level. Bentonite clay has an alkalizing effect, which can neutralize the acidity that often results from consuming acidic foods and beverages. Maintaining a less acidic, more alkaline environment inhibits the proliferation of harmful bacteria that contribute to enamel erosion and decay.
The physical and mineral composition of the clay offers direct benefits to the teeth. Bentonite clay is a source of trace minerals, including calcium, magnesium, and silica, which are materials that make up tooth enamel. While the clay does not directly rebuild enamel, these minerals enrich the saliva, supporting the body’s natural remineralization process. The fine, silty texture of the powder also acts as a mild abrasive, gently polishing the surface of the teeth to remove plaque and surface stains without causing excessive wear.
Essential Preparation and Safety Guidelines
Proper preparation of bentonite clay is necessary to preserve its unique cleansing properties. Strictly avoid using metal bowls, spoons, or utensils when mixing, stirring, or storing the clay. Contact with metal can neutralize the clay’s electrical charge, diminishing its ability to attract and adsorb impurities. Always use tools made of glass, ceramic, wood, or plastic.
To create a usable paste, combine the dry powder with a small amount of purified or filtered water. Use non-chlorinated water, as chemicals like chlorine can interfere with the clay’s mineral structure. Start with a general ratio, such as two parts clay to one part water, and stir until the consistency is similar to a thick, smooth toothpaste. Allow the mixture to hydrate for a few moments, as the clay will swell and absorb the liquid.
For safety, ensure the product you purchase is explicitly labeled as food-grade or pharmaceutical-grade bentonite clay. This labeling confirms the clay is purified, safe for internal use, and tested for potential heavy metal contamination. While small, accidental amounts ingested during brushing are not a concern, the clay is not intended to be consumed in large quantities. Be aware that the fine clay powder can stain fabrics, and the thick clay paste should be rinsed thoroughly down the drain with plenty of water to prevent potential clogging.
Specific Methods for Using Clay on Teeth
One of the most common applications is using the clay as a natural toothpaste substitute. You can use the prepared paste or simply dip a damp toothbrush directly into the dry clay powder. If using the paste, apply a pea-sized amount to the bristles. Brush gently in circular motions for approximately two minutes, focusing on the surfaces and along the gumline to maximize the clay’s polishing and cleansing action.
A more intensive application is using the clay as a remineralizing mask. After brushing with the clay paste, or mixing a slightly thicker slurry, apply a thin layer directly onto the surfaces of your teeth. Allow the clay to remain on the teeth for about five minutes before rinsing thoroughly with water. This contact time allows the minerals to interact with the mouth environment, supporting the enrichment of the saliva.
The clay can also be used as a detoxifying mouth rinse to cleanse the entire oral cavity. Mix a small amount of clay, typically a half-teaspoon, into a quarter-cup of filtered water to create a thin, milky slurry. Swish this mixture vigorously around your mouth and through your teeth for 30 seconds to one minute. This action helps the clay adsorb impurities from the gums and tongue.
After using any of these methods, always spit the clay mixture out and rinse your mouth thoroughly with clean water. Because of the clay’s powerful cleansing action, incorporating the clay into your routine a few times per week, rather than daily, is often sufficient. You may choose to alternate the clay with your regular toothpaste to maintain a balanced hygiene regimen.
