Are all tooth whitening kits as effective? Do they all put the same ingredients in the product?
At the discount store they have tooth whitening kits with the gel and mouthpiece for a dollar, and then at the more higher end stores they have them there but for about 30 - 70 $ per kit, the ingredients are the same , I think ?
Commercial tooth whiteners use hydrogen peroxide and are expensive and inconvenient. A cheap and natural tooth whitening home remedy uses few strawberries but certain precautions have to be taken. I found the information at http://www.aches.in/toothwhitening.html
