What happens if an impacted tooth is not removed from the mouth?
Damage to the adjacent tooth or teeth: If an impacted tooth is put in a position that allows it to impinge on the adjacent tooth, eruption pressure can cause damage to that tooth. This might cause bone loss and pain in the surrounding tooth.
Pericoronitis occurs when the tissues surrounding an impacted third molar become inflamed, resulting in food impaction and pain radiating to the head and neck region.
Trismus: An erupted third tooth can make it difficult to open the mouth and may also cause pain.
Cheek biting: A displaced tooth can cause cheek biting and irritation in the cheek.
