Does Teeth Whitening Cause Sensitivity?

February 17, 2025


We all want to have a bright, white smile; in fact, according to a survey by the American Academy of Cosmetic Dentistry, it is the single aspect that most Americans would like to improve about their smile. Professional teeth whitening treatments can significantly improve the appearance of your smile by reducing yellowness and removing stains, but some people are hesitant to try them. The main reason why is that they are concerned that undergoing professional teeth whitening will cause their teeth to become more sensitive.

At American Dental, we perform countless teeth whitening procedures every year, and we always advise our patients about potential side effects. If you’re forgoing that teeth whitening treatment because you are concerned it will cause tooth sensitivity, read on to find out more about this procedure and how it can affect you!

Discoloring of the Teeth

Many factors can cause the teeth to become yellow or stained. Most commonly, yellowing and stains come from the foods and beverages we consume. Frequently drinking coffee or red wine, for example, can cause teeth to become increasingly yellow over time. Smoking is another common lifestyle factor. Those who use tobacco products – smokeless or otherwise – are more likely to have yellow or stained teeth. Aging can also cause teeth to become yellow. The older you are, the more likely you are to have stains or yellowing of the teeth.

Treatment for Yellow or Stained Teeth

The most common methods used to reduce yellowing and remove stains on the teeth involve using chemical agents like hydrogen peroxide or carbamide peroxide. These chemicals produce an oxidation reaction that bleaches the teeth, and any staining agents are absorbed into the tooth enamel and dentin. In some procedures, UV lights accelerate the process and produce a more pronounced result.

While it is possible to give yourself a DIY tooth whitening treatment at home using commercially available products, having the procedure done by your dentist will provide better results in less time.

Sensitivity After Tooth Whitening

It is a fact that tooth whitening, whether it is done at home or professionally, causes increased sensitivity to heat, cold, and acid. It’s the most common side effect of the treatment that our patients report. That’s because the whitening agents can penetrate the tooth enamel and dentin, stimulating the nerves underneath and making them more susceptible to sensitivity in the future.

While tooth whitening does cause sensitivity, this effect is not permanent. Sensitivity will be most pronounced for a day or two after the treatment and gradually subside over a week. Once the sensitivity is gone, you can enjoy your new, whiter smile and even consider additional treatments until you achieve the look you desire. Despite any minor, temporary sensitivity, the benefits of tooth whitening outweigh the negatives for most of our patients.
