As recommended by the American Dental Association wisdom teeth need to be removed for the following reasons:
Wisdom teeth only partially erupting can leave an opening for bacteria to enter around the tooth and cause an infection. Pain, swelling, jaw stiffness, and general illness can result.
There is also a chance that poorly aligned wisdom teeth will damage adjacent teeth or significantly alter the growth of adjacent teeth. The above panoramic x-ray shows the bottom left wisdom tooth applying pressure to the lower jaw and surrounding teeth. A cyst (fluid-filled sac) may form, destroying surrounding structures such as bone or tooth roots.
Wisdom teeth (or third molars) usually appear between the ages of 17 and 25 years. Nearly a quarter of the population will not develop wisdom teeth. The best way for Dr. Simer to diagnose any patients best course of action is through an x-ray.
