Will Kor Deep Bleaching Work for Someone Who Has Never Had White Teeth?
I have tried Nite White 22% in the past, but it never did much lightening if any. My teeth grew in yellow and I'm afraid the Kor will not work either. I don't see much on the internet about it. I have been to their site and it sounds promising, but still skeptical. I am happy with the shape of my teeth and am wanting white teeth only. Does Kor lighten surface stains only? Mine are not surface stains. What about relapse? My teeth would look a little lighter with NW, but only for about 10 minutes.
