If the impacted tooth does not fully erupt it can cause additional problems than a fully erupted tooth. One or more of the problems listed below can occur with varying intensity at different times. Infection is the most common problem around the gums and the bone and can even extend onto the face and neck. These infections can affect the general health of the individual. It is also possible for the impacted tooth to cause crowding and damage to adjacent teeth. A more serious complication is when a sac develops around the impacted tooth and it fills with fluid and enlarges to form a cyst, which causes a hollowing out of the jaw, and can results in permanent damage to the adjacent teeth and jawbone. No one can predict if or when an impacted tooth will cause some or all of these problems, but problems could arise and complicate management. Therefore it is recommended if the impacted teeth are not removed that appropriate and regular radiographs be taken to determine if problems can occur now or in the near future.
