I got free teeth whitening a couple of months ago and I think that it is started to damage my tooth enamel. My teeth are starting to a weird color. Also they are super sensitive to anything cold. Sometimes even if I am not drinking anything cold, I get this powerful shock in my teeth that really hurts. I took ibuprofen last night and that seemed to help. At first I really thought the stuff was working because my teeth looked whiter. Now they don’t look or feel good. I guess I should stop using it. Can it permanently damage my tooth enamel? Thanks. Joseph

Joseph – You should stop using the free teeth whitening. You didn’t mention how often you use the whitening gel, but if you are using it more than once a month, you are probably using it too often.

Any type of bleaching gel, if used frequently, can weaken your tooth enamel and even discolor your teeth. If bleaching gel is professional strength, usually touchup treatments are needed once or twice a year. If you smoke or drink daily, touchups may need to be more frequent, perhaps quarterly.

But bleaching your teeth daily or weekly should be avoided. Teeth whitening treatments that are unsupervised by a dentist can damage your tooth enamel. Your teeth can become translucent and very sensitive.

Schedule an appointment with a dentist to examine your teeth and to look at the ingredients in the bleaching gel you are using. The dentist will be able to determine if your free teeth whitening gel is causing the sensitivity in your teeth and if it has done any lasting damage to your teeth.

Some dentists offer free teeth whitening or discounted teeth whitening to patients who maintain their regular cleaning and examination appointments. This is a safe way to brighten your smile and get predictable results. Your dentist will monitor the progress and decrease or increase the strength of the bleaching gel, depending on how it is affecting your teeth. He or she will also let you know how frequently you should do touchups.

Schedule an examination with an experienced cosmetic dentist as soon as possible.
