Wow you got pearly white teeth! How did you make it that white? You must have used teeth whiteners huh? Didn't you hear that they cause cancers? Researchers from Georgetown University Hospital said that the active ingredient in most whiteners, which is carbamide peroxide, can come in contact with the gums. Peroxide can produce free radicals, molecules that may lead to cancer. But they haven't proven this yet and i assume that there is less evidence. If you're worried like me then for the meantime let's stop using whiteners first. If you insist on doing them, follow the
instructions and don't overdo it. Just brush your teeth every after meal, and don't brush it quickly as your teeth won't be able to absorb the fluoride. I know it's nice to have white teeth but we should consider the possible effects of these teeth whiteners too. The best thing to do is for everybody to wear a banana smile!!!
