High Exposure Risk — Why This Product Category Matters

The mouth is one of the most absorptive areas of the body. Toothpaste, mouthwash, and dental products are in contact with oral mucosa for minutes daily. Fluoride, triclosan, artificial sweeteners, microbeads, and synthetic fragrances in conventional oral care products are absorbed directly into the bloodstream.

Why We Recommend This Product

Dr. Bronner's mouthwash is one of the cleanest formulas available. No alcohol (which disrupts the oral microbiome), no synthetic dyes, no artificial sweeteners. The organic peppermint oil provides effective antimicrobial action.
