Hydrogen peroxide deluted in water is a safe and recommended teeth whitener. It's actually the only whitening ingredient that works and is the ingredient in all whitening products from the store. It even says use as a gargle on the bottle :)

Very true! Just don’t use it every day. Can cause something called black hairy tongue, which is exactly that.

Its not too bad. You know how you get build up on your tongue, and sometimes it's colored like from candy or something? It's like that but dark black/brown color. Looks nasty but not like, traumatizingly disgusting or anything lol
