Ask the Dental Experts

I have been considering having my teeth whitened by by dentist with a laser procedure. I have heard that this can cause your teeth to become sensitive and sometimes painful. Is that true?

Thanks for the question. First of all, most in office whitening procedures are done with out a laser. In the past, a laser was used to warm the bleaching solution to speed up the bleaching process. Numerous studies and our clinical experiences have shown this can cause your teeth to be very sensitive. The degree of sensitivity ranged from no discomfort to extreme discomfort. In all cases of bleaching sensitivity the discomfort experienced by the patient was completely resolved with in two to three days.

As a result of sensitivity problems from laser bleaching we have switched to using a high-density light that gives us the same results as a laser with little or no sensitivity. We recommend a combination of in-office and at-home bleaching because we’ve found that this method works best to lesson and control sensitivity while obtaining maximum whitening results.

Our patients are very happy with the significant drop in sensitivity and with their whitening results. They are able to keep their teeth at maximum white by using the home bleaching trays one or two days every four to six months.

Again, I want to thank you for your bleaching question. I welcome you to call for an appointment to further explore your bleaching options.
