Exposure of Impacted Teeth
A tooth may become impacted or stuck in a position where it fails to erupt into the mouth. This condition is known as impaction and can occur in either primary (deciduous) or permanent teeth.
Patients most commonly develop impaction with the third molar or wisdom teeth (see Impacted Wisdom Teeth) which are usually extracted if they develop any problems. For all other teeth, the goal is to erupt the teeth at an early age because, as a child becomes an adult, the roots of the tooth become less elastic and able to adjust as needed for eruption.
