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 Rated It This Way
Listerine contains synthetic dyes, saccharin, and synthetic fragrance — all applied to the highly absorptive oral mucosa. The alcohol content also disrupts the oral microbiome. Oil pulling with coconut oil or a clean mouthwash formula is a safer alternative.
