Teeth whitening-does it work?
I hate my teeth and would like to try some of these teeth whiting products that you see dotted all over the internet. I am curious to underatand how these things actually work. I drink a lot of coffee and the odd glass of red wine so I need something that would eliminate these kind of stains. I visit the dentist every six months but feel that I need something extra that would make my teeth a little brighter. Do these products adversely effect the enamel in any way or are they simply peroxide based in which case it would bleach the teeth I would like to know the answer.
