Remineralizing #ToothPowder Recipe

By Merilin Vrachovska Posted on June 24, 2021 Updated on April 15, 2026

"Creating your homemade tooth powder is one of my favorite DIYs. It’s affordable, effective, and gives you full control over what goes into your oral care routine.

Plus, it promotes remineralization – a natural process that helps repair and strengthen enamel to prevent decay.

In this guide, I’ll show you how to make a simple and sustainable DIY remineralizing tooth powder, why each ingredient matters, how to use it, and answer common questions based on my personal experience.

Unlike conventional toothpaste, this one contains no fillers, foaming agents, or unnecessary additives. It’s pure, natural, and effective.

Ingredients & benefits

Bentonite clay

Bentonite clay is naturally mineral-rich (calcium, magnesium, silica) and gently abrasive. It raises your mouth’s pH and binds to toxins and bacteria, making it perfect for oral detox. It’s not abrasive enough to damage enamel and helps reduce bad breath.

Always use food-grade bentonite clay from a reputable source. Because it’s sourced from the earth, it can absorb heavy metals if not tested properly. Avoid using metal utensils when handling them – use ceramic, glass, or wood instead.

Alternatives: Kaolin clay is also effective if you don’t have bentonite.

Where to buy plastic-free bentonite clay: Zero Waste Bulk (the US), A Drop In The Ocean (the US), All Things Being Eco (Canada), Zero waste store (Australia) Make your own natural beauty without the waste

Baking soda

Baking soda is an antimicrobial powerhouse. It gently polishes teeth, helps neutralize acids in the mouth, and supports enamel remineralization.

Studies have shown that brushing with baking soda reduces plaque and enhances stain removal without increasing tooth sensitivity.

Also, baking soda is actually one of the least abrasive options out there – it scores low on the RDA scale, which means it’s much gentler on your teeth than most commercial toothpastes. That’s why it’s perfect for a tooth powder recipe.

Tip: Use soft-bristled brushes and avoid applying heavy pressure to keep abrasiveness low.

A curious fact: An article in a leading dental journal from 1911 described baking soda as “the ideal tooth powder”, capable of “giving a high polishing to the teeth, without the danger of scratching them.”

Xylitol

Xylitol is a must for cavity prevention. This natural sweetener (often from birch) not only improves the taste, but also fights the bacteria that cause plaque, gum disease, dry mouth, gingival inﬂammation, and tooth decay. It helps maintain a healthy oral environment and even stimulates saliva production, which supports remineralization.

Essential oils

- Peppermint oil – Soothes toothaches, kills odor-causing bacteria, and adds a fresh flavor. 
- Cinnamon oil – Antioxidant, antimicrobial, and known to fight bacteria responsible for cavities. 
- Clove oil – Antimicrobial and anti-inflammatory. Effective for gum issues and oral pain.

Allergy warning: Always patch test essential oils before use. If you’re sensitive, you can skip them and add extra xylitol for flavor.
