Question about Hydrogen Peroxide and teeth whitening?
So I heard that you can whiten your teeth with hydrogen peroxide and to apply it about 2-3 times a day
I have school pictures in 2 weeks and my teeth aren't very bright.
but my question is for how long should i leave it in for?
and have you tried this? if you did how did it work?
this is the best website i could show you that deals with h202
