🦷 DIY Remineralizing Toothpaste

**revised recipe April 2026

Looking for a natural, effective toothpaste that supports enamel health without fluoride? This homemade DIY remineralizing toothpaste is a game-changer, especially for those with sensitive teeth or mild enamel erosion. Made with microcrystalline hydroxyapatite powder (the same mineral structure your teeth are made of), bentonite clay, coconut oil, and a few other powerhouse ingredients, it’s simple to whip up at home and gentle enough for daily use. It's completely customizable for your needs.

DIY Remineralizing Toothpaste

What You Need:

• 2 tablespoons Bentonite Clay

• 1 tablespoon Microcrystalline Hydroxyapatite Powder (MCHA)

• 2 tablespoons Coconut Oil (soft or melted & adjust for desired consistency)

• 1 tablespoon Xylitol (optional, for sweetness and enamel support)

• ½ tsp Ground Cloves (for gum support and flavour)

• 5-10 drops Peppermint Essential Oil (optional, for flavour & freshness)

What To Do:

1. Combine Dry Ingredients: In a non-metallic bowl, mix the bentonite clay, hydroxyapatite powder, cloves, and xylitol (if using).

2. Add Coconut Oil OR Distilled Water: Gradually add coconut oil or water (please see special note on water below), stirring continuously with a wooden or plastic spoon until you achieve a smooth, paste-like consistency.

3. Incorporate Essential Oil: Add the peppermint essential oil and mix thoroughly.

4. Store Properly: Transfer the toothpaste into a glass jar with a tight-fitting lid.

How To Use:

• Dip your toothbrush into the paste or use a small spatula to apply a pea-sized amount onto your brush.

• Brush as usual, then rinse your mouth thoroughly.

Notes:

• Avoid Metal Utensils: Bentonite clay can absorb metals, which may reduce its effectiveness. Use wooden, plastic, or glass tools.

• Consistency Adjustment: If the paste is too thick, add a little coconut oil or distilled water (see special note on water below) ; if too thin, incorporate a bit more bentonite clay (for some people, bentonite clay may feel too strong or slightly abravise, if needed, reduce the amount of bentonite clay).

• Storage: Keep the toothpaste in a cool, dry place. Use within 2-3 weeks for optimal freshness.

• ****Special note on water and shelf life: Adding water to your toothpaste can shorten its shelf life due to the potential for bacterial growth and contamination. Because this recipe doesn’t contain preservatives, moisture creates an environment where microbes can grow over time. To extend shelf life, make smaller batches (2-3 weeks at a time), use a small spatula or popsicle stick to scoop out toothpaste rather than dipping directly into the jar.

Sourcing Ingredients:

• Microcrystalline Hydroxyapatite Powder (MCHA): https://lightcellar.ca/products/hydroxyapitite-powder?variant=43080079900848

• Bentonite Clay: Available at health food stores or online retailers.

• Xylitol and Essential Oils: These can be found at health food stores or online.

🔍 Ingredient Breakdown: How It Helps + Limitations:

🪨 Microcrystalline Hydroxyapatite Powder (MCHA)

• How it helps: Biomimetic form of tooth enamel that can rebuild micro-damage, reduce sensitivity, and strengthen enamel...especially effective for early-stage enamel erosion.

• Limitations: Cannot restore enamel if significant structural damage, corrosion, or cavities are already present. Works best as a preventative and for mild to moderate erosion.

🌿 Bentonite Clay

• How it helps: Rich in minerals (calcium, magnesium, silica); binds to toxins, bacteria, and heavy metals while supporting oral detox and pH balance.

• Limitations: Doesn’t actively rebuild enamel; instead, it creates a cleaner, more alkaline environment for remineralization to occur. May be slightly abrasive for some people.

🥥 Coconut Oil

• How it helps: Naturally antibacterial and antiinflammatory due to lauric acid, which supports gum health and reduces plaque-causing bacteria. Also adds smooth, spreadable texture.

• Limitations: Doesn’t directly remineralize teeth; best used as a supportive carrier and antimicrobial.

🌱 Xylitol (optional)

• How it helps: Prevents bacterial adhesion to teeth, reduces cavity risk, and promotes saliva flow, which supports the mouth’s natural remineralization process.

• Limitations: Some people may be sensitive to sugar alcohols (bloating or digestive upset if swallowed), and it's toxic to pets, so must be stored safely.

🍂 Ground Cloves

• How it helps: Contains eugenol, a natural analgesic and antiseptic that supports gum health, reduces inflammation, and soothes minor toothaches.

• Limitations: Strong flavor may not appeal to everyone; overuse can cause mouth sensitivity or irritation in some people.

🌬️ Peppermint Essential Oil (optional)

• How it helps: Provides a fresh taste and a mild antibacterial effect. Supports a clean mouth feel and combats bad breath.

• Limitations: Must be food-grade and used in moderation to avoid mucosal irritation. Some may have sensitivities to essential oils.

Other Important Factors for Enamel Remineralization:

• Diet & Nutrition: Adequate calcium, phosphorus, vitamin D, and magnesium are essential for strong teeth.

• pH Balance: Reducing acidic foods/drinks (like soda and citrus) prevents further enamel erosion.

• Saliva Production: Staying hydrated and eating mineral-rich foods (like leafy greens) supports natural remineralization.

What to Do Next:

If your enamel corrosion is minor (surface-level erosion), using microcrystalline hydroxyapatite toothpaste, bentonite clay, and proper nutrition may help remineralize it. If the damage is more severe (visible corrosion, sensitivity, rough texture), consulting a dentist for professional remineralization treatments or bonding may be necessary.
