Hydrogen pyroxide is poisonous!!! Inhaled or swallowed it can cause dammage to lungs and mucus membranes. Brussing teeth with it is asking for trouble. That said, using harsh chemicals like Hydrogen peroxide and baking soda can damage the enamel on the teeth. This makes teeth more susceptable to decay. Pleeeeeaase, just use normal tooth paste with floride. If you really need whiter teeth let a dentist do it properly. Tip: Darker lipstick will make your teeth look whiter.
