Reasons Your Teeth Hurt After Whitening


Do you have thin enamel? This is usually the first thing we will look for if you are experiencing pain after whitening treatments. However, patients with strong enamel may still experience some discomfort after whitening. Peroxide, one of the main ingredients in whitening solutions, can irritate the nerves in your teeth, which is probably why you experience discomfort when drinking something cold or when you go outside in cold temperatures.


How Long Should My Teeth Hurt After Whitening?

If you experience pain after whitening, it should subside within 24 to 48 hours. If it lasts longer than this, contact your Lane dentist immediately.


How Can I Prevent Tooth-Whitening Pain?


If you know that you have sensitive teeth, ask your dentist about a desensitizing toothpaste to help counter any whitening-related discomfort you might have after your treatment. You can also ask your dentist about using potassium nitrate in your whitening tray, as it has been known to help reduce tooth pain.


You can also take an anti-inflammatory as a proactive measure before your whitening appointment. Brush your teeth before your treatment, not after. Doing so after will further expose the dentin of your teeth, which will exacerbate any sensitivity. Brushing after whitening can also damage your enamel, and once that’s gone, you can’t get it back.

If whitening-related sensitivity is still a problem, consider reducing your amount of whitening treatments. Remember to also use a soft-bristle brush and warm water to combat any lingering sensitivity issues.


Is Tooth Whitening Safe?


Despite some discomfort for patients with sensitivity, tooth whitening is a safe cosmetic dentistry practice when done currently. If you whiten at home, be sure to follow the directions and never leave strips or trays in for longer than suggested. If you have your whitening done at our dentist’s office, you can be confident that your dentist is using safe techniques and materials. Feel free to ask for more information from your dentist if you have any questions.
