The lozenge produces new enamel that is whiter than what tooth-whitening strips or gels produce. It has another distinct advantage: Conventional whitening treatments rely on hydrogen peroxide, a bleaching agent that can weaken tooth enamel after prolonged use. Since tooth enamel can’t regrow spontaneously, the underlying dentin can be exposed, with results ranging from hypersensitivity to cavities or even gum disease. The lozenge, on the other hand, strengthens, rebuilds, and protects teeth.
'Sweets that are good for your teeth!', sounds to good to be true. If they really work, theoretically couldn't these same active ingredients be added to conventional toothpaste as well. Me own gnashers are in dire need of some new, strong, white enamel.
