do teeth whitening trays work?!

yeah they do,bleaching trays can be a good alternative to various costly teeth whitening options.you can get them done at your dental office or sometimes like at the mall you can get one made there:) but yes its a good thing your taking an interest in your teeth.but it can be like 200 bucks!

I think it depends more on how strong the solution is of the bleaching gel you use, but yes overall bleach trays work pretty well.
