What should I do if Whitestrips irritate my gums or cause my teeth to be sensitive?
• As with any teeth whitening system that contains peroxide, teeth/gum sensitivity may temporarily develop when using Crest 3D White Whitestrips. Some people may experience tooth sensitivity or gum discomfort when using this or other whitening products. If significant tooth sensitivity or gum discomfort develops, try using the strips every other day. If the problem persists, discontinue use. Using a teeth whitening system on teeth that are already sensitive may increase the level of discomfort that you normally experience. If you have sensitivity concerns, we recommend you try Crest 3D White Whitestrips Gentle Routine for teeth sensitive to whitening.
