Yes. Teeth whitening can cause minor sensitivity, which usually fades within a few days after your procedure is complete. This is common and to be expected. You can use a desensitizing toothpaste to help reduce feelings of discomfort.
It’s also important to brush regularly during and after teeth whitening treatment. Using fluoride toothpaste helps strengthen the teeth and may help reduce whitening-related sensitivity. Avoiding very hot and cold foods for a few days can also help reduce the effects of sensitivity.
Whitening Sensitivity Is Usually Temporary
The American Dental Association explains that some people who use teeth whiteners may experience tooth sensitivity, which happens when the peroxide in the whitener gets through the enamel to the dentin and irritates the nerve of the tooth, and that you can delay treatment and then try again. It adds that overuse of whiteners can also affect the tooth enamel or gums, so it is important to follow directions and talk with your dentist at your next dental exam. This supports the point above that whitening sensitivity is common and usually short-lived.
“In most cases the sensitivity is temporary.”
