Is it safe to use hydrogen peroxide to whiten my teeth?

Only from a DDS: Peroxide can injure your gums. Only the medical grade bleaching from your dentist is safe.

In what form?: All whitening strips and gels use either hydrogen peroxide or carbamide peroxide in different concentrations. They are generally safe because the company formulates the gel with approved methods, and your dentist creates a custom tray to protect your teeth. I do not recommend trying peroxide straight out the bottle as a home whitening remedy.
