Baking soda has for many decades been used for tooth care practices, such as tooth brushing, either by itself, in combination with salt or with other ingredients in a dentifrice. It has been selected by Isabelle, the creator of Good-Gums®, as a principal ingredient of Good-Gums® powdered dentifrice.
Baking soda is an excellent natural dental care product.
The primary virtues of baking soda are that it neutralizes acids and that it acts as a very good cleanser and deodorizer. Baking soda is nontoxic and mild enough for the soft tissues of the gums, tongue and mouth. It's one of the least abrasive cleansers on tooth enamel, much less than the silicas or dicalcium phosphates that are common to many toothpastes. Baking soda neutralizes odors and bad tastes, instead of just covering them up with a stronger scent and taste. Odors from strong acids like sour milk or from strong bases like spoiled fish are weakened by being neutralized by the natural buffering action of baking soda. The buffering action also helps maintain a stable pH balance in the mouth.
Baking soda also neutralizes Volatile Sulfur Compounds, which are primarily responsible for bad breath (mouth odor). Clinical studies show that VSCs are highly toxic, even at low concentrations, and studies are underway to determine their involvement in gum health issues. VSCs tend to congregate in the gum pockets, especially as pockets get deeper, where anaerobes can proliferate and produce VSCs.
Isabelle recommends that the dissolved solution of Good-Gums® be held in the mouth briefly after brushing, as this may help the solution reach further into the gum pockets where it may help neutralize the VSCs there. At this point, this connection must legally be considered only a conjecture, since we currently lack a clinical study specifically validating the interaction of Good-Gums® with the microbes and VSCs found in gum pockets.
Another virtue of the natural dental care product, baking soda is that it helps remove stains on the surface and in the tiny crevices of teeth. So if you drink coffee, tea, wine or even smoke, baking soda may help improve your teeth's appearance.
