For what?: To whiten your teeth? It really doesn't work. Purchase products specifically formulated for tooth whitening. If the purpose is not for whitening, then buy a fresh bottle... Its really inexpensive, and expired H2O2 is just water.

Not recommended: Hydrogen peroxide is safe to use topically for your teeth, if not expired. However, do not use hydrogen peroxide as a regular part of an oral care routine.
