Why does the package state that Sensodyne® should not be used longer than 4 weeks unless recommended by a dentist or physician?
The FDA requires this statement on the packaging of all over-the-counter desensitizing toothpastes. Sensitive teeth may indicate a more serious problem (cracked tooth, faulty restoration, etc) that may need to have prompt care by a dentist. See your dentist if the problem persists or worsens. Your dental professional may recommend the safe use of Sensodyne beyond four weeks if he or she has ruled out other dental or medical causes.
