I know, i know this has been a topic on here time and time before i can't find it!! I am thinking of getting some of the crest teeth whitening strips and there seems to be a lot of different ones on ebay, i need help - which would you recommend? I'm not a smoker or red wine drinker, they're just quite dull and yellowish but would love that beaming white smile
I went on crest website and the latest one seems to be Advance Seal - has anyone used these??
