Is there a cheap tooth bleaching procedure?

The store: You can try the pharmacy. However you get what you pay for. Try to save up and have bleaching done professionally. Make sure you do not have any cavities or gum disease as the bleaching can cause severe pain if any of these problems are present.

Crest Strips: You can get the crest strips at some stores. They will have an effect. You should have your teeth cleaned before you start bleaching to get the best result. You should get a better result from having it done professional by a dentist.
