IPA COPYRIGHT: ASHP Studies of the use of lactic acid and its salts as active ingredients in toothpaste and other oral hygiene products to prevent tooth decay and freshen breath are discussed. It was noted that the calculus scores of subjects using calcium lactate-containing toothpaste were significantly reduced. The aluminum salt has been shown to have a beneficial effect on the gums and mucous membrane of the mouth. Because of its food solubility and relatively mild taste, the zinc salt may be suitable for combating gingivitis and oral malodor.
