You know what it's like to have your teeth hurt -- by light, air, breathing, cold, hot. I'm not talking about a tooth ache! I'm talking about straight bleach/peroxide gel soaking that is what they call "Teeth Whitening".
It's not so much fun, but damn if it ain't worth it! I'm on day 3 and I already see a HUGE difference -- coming from guy who smoked like freight train and had yellow teeth.
