Why do i get intense sharp pain in my tooth when using crest white strips? same spot every time. how can i still whiten my teeth and avoid this?

See your Dentist: You may have a cavity, or exposed root surface, or a fractured tooth. Please have your Dentist investigate, treat, and then help you safely and effectively whiten your teeth. Remember that tooth whitening is not a cosmetic procedure like coloring your hair. It's a procedure that alters the actual structure of your teeth. Please see your Dentist.

Whitening pain: Most whitening methods can cause tooth sensitivity. This usually is related to the whitening materials affecting the dentin of the tooth which is not covered by enamel. However what you describe is more likely related to gingival recession, a cavity or decalcification, a defective or leaking filling, incisal\occlusal abrasion or erosion, etc. See a dentist to see if treatment is needed.

Check for cavity: I hope you have a general dentist that already checked you for possible cavity. If it is confirmed , then it is safe to use teeth whitening strips. You can use desensitizing tooth paste to mange srnsitivity.

The most common se: The most common side effect (se) of using crest white strips is tooth sensitivity. In this case I would recommend not using any kind of teeth whiteners Over The Counter. See your dentist for a painless and predictable laser whitening system. Good luck.

DDS bleach: Suggest dental supervised whitening period. The dentist can titrate the percentage of bleach used dependent on factors such as sensitivity and intrinsic staining. Over the counter products are not customized and do not give the same results. Any sensitivity should be transient, if problematic speak with your dentist.

Possible Wear: It sounds like there might be a spot that has been worn or abraded on the specific tooth you are mentioning. The best way to control that is to go see your dentist and possibly have them make you custom trays for at home whitening. The office whitening gels come in different concentrations and they also contain fluoride as well as substances for sensitivity. this should help
