Coral White may help to prevent cavities by raising the pH (alkalinity) of your saliva, whitens teeth and freshens breath. Because of the unique whole food mineral complex from Coral White's Coral Calcium, it may help to re-mineralize tooth enamel. Combining hydrogen peroxide for its gentle whitening effect with spearmint and peppermint oils makes a highly effective and great tasting toothpaste! No fluoride or sodium lauryl sulfate.
