How long does it take for lemon and salt to make your teeth white?


Rate This Answer

Lemon Lemon juice is an acid and can harm your teeth. You may end up with a LOT of cavities and irreparably damaged tooth enamel. The reason that lemon juice 'works' is that it causes the teeth to lose calcium. Calcium is a major component of healthy teeth, and once it is lost, your teeth become very susceptible to decay. Do not use lemon juice for whitening. ChaCha!
