How do "professional" and "over-the-counter" teeth whitening differ?

The major difference between "over-the-counter" and "professional" whitening treatments, is that when you do it "over-the-counter" you're on your own. When you have the whitening treatment done professionally, not only are the trays made to fit you better, but someone is going to watch over you to make sure that you don't have major problems with the gum because the bleach was too strong and burnt the gum, or the gums don't have major sensitivity. So if you do decide to do it "over-the-counter", be aware that many things can happen during your whitening treatment and you have to be careful about that.
