Occasionally a tooth will not erupt into its proper position because it is impacted. Most of us are familiar with the term impacted wisdom teeth. However, sometimes teeth such as upper and lower canines, bicuspids, and even incisors can be a problem. A surgery can be performed which exposes these teeth and allows for their eruption. Most frequently, an orthodontist will diagnose this situation and make the referral to a periodontist for this surgery.
