can you use whitening strips if you have crooked teeth? if so what's the easiest to put on,take off and don't have to wait a long time to eat or drink something either whitening strips or trays? which whitening kit is the cheapest?
--------------------
I think you can, but just make sure the whitening gel gets evenly applied.. you might be missing some spots. Try a whitening pen, $12.99. more peroxide than the strips.Good luck
