If you occasionally experience a sudden flash of pain, or a mild tingly feeling when you bite into sweet or sour foods, or drink hot or cold beverages, you may have sensitive teeth.
Many people are unaware that they clench or grind their teeth while asleep. Signs can include sensitive or even chipped teeth.
Depending on the diagnosis, your dentist may recommend various changes to your dental hygiene routine, such as: a soft(er)-bristled toothbrush; a special toothpaste for sensitive teeth that can either block access to the nerve or make the nerve itself less sensitive; a fluoride rinse or gel for sensitive teeth. A sensitivity-protection toothpaste usually takes several weeks to ease pain. Follow the instructions of your dental professional on the regular use of sensitivity protection toothpaste to keep pain from returning.
