I have a damaged incisor that has always been a bit darker than the other teeth. It has started to embarrass me now that I am older. I wanted to whiten it, so my dentist suggested I try Crest Whitestrips. I bought their strongest. After a week, that tooth started to hurt, so I stopped using them. However, the tooth doesn’t seem to be getting any better. It is sensitive to both cold and heat. Do you think it needs a root canal treatment? Is it normal for teeth whitening to do that?

Dear Livvie,

In general, using Crest Whitestrips are safe. That is mostly true because they are not very strong. For safety reasons, the over-the-counter brands are weaker than what you would get if you were doing teeth whitening with a dentist. I’ve only heard of one other time someone needed a root canal treatment after using Crest Whitestrips and the situation is eerily similar to yours.

My recommendation would be to have your dentist do a cold test on your teeth. That will help him know if the tooth needs further treatment.

The Right Fix for a Dark Tooth

One further thing here. Crest White strips (or any teeth whitening) was the wrong treatment for this. When your teeth are whitened, they whiten uniformly. That means the dark tooth would still be darker than the other teeth.

A better treatment for this would have been either dental bonding or even a porcelain veneer. Either way, don’t allow your current dentist to do the treatment.

Teeth whitening is one of the easiest cosmetic procedures available. Every dentist should be able to do it properly. It seems, however, that your dentist doesn’t understand even that. Dental bonding and veneers are much more advanced. When you are ready to get this tooth fixed, you will want to seek an expert cosmetic dentist.
