(HealthDay News) -- Wisdom teeth are the third set of molars that usually appear between ages 17 and 21. They often lack enough room to come in normally, and should be removed to prevent pain and possible infection.
The American Dental Association says warning signs that wisdom tooth need to come out include:
- Cysts in the mouth.
- Damage to neighboring teeth.
- Gum disease.
- Tooth decay.
