Why does Aquafresh® Sensitive Maximum Strength toothpaste warn against using longer than 4 weeks?
The FDA requires warning on the labels of all sensitive teeth toothpastes. It is meant to advise consumers that if brushing with a desensitizing toothpaste does not eliminate the pain, then what they believe is a sensitive tooth may actually be something that needs to be treated by a dentist (i.e., faulty restoration, cracked tooth or infected pulp).
