Fiction: Tooth Sensitivity Is Normal

If you have sensitivity to hot or cold drinks and food, or you feel pain when you bite down on something, a visit to the dentist is in order. “Tooth sensitivity is never normal,” says Dr. Malterud. “It’s an indication that there’s some underlying issue such as a cracked tooth or cavity and should be evaluated by your dentist.” Sensitivity may also be caused by tooth whitening products, excessive consumption of acid-containing foods, soft drinks, acid reflux and tooth grinding or clenching. (If you've had a recent restoration, like a filling or crown the pain should calm down in a few weeks). A desensitizing toothpaste may help, but don’t expect immediate relief. You’ll need to use it for a month to see results.
