Abstract
A chewing gum for highly efficient and quick plaque and tartar removal and inhibition including pure ascorbic acid crystals and/or granulars (vitamin C) and an enamel repairing composition such as a blend of hydroxyapatite crystals and sodium fluoride. The chewing gum can contain at least 20% of ascorbic acid without compromising the integrity of tooth enamel because hydroxyapatite will repair any damage to the enamel.
