Occasionally teeth do not come into the mouth, or erupt, normally. Instead they can become impacted, meaning they are blocked from erupting.

If a tooth is impacted, the tooth must be uncovered, or exposed, with a periodontal surgical procedure. During this procedure, once the tooth is exposed, a small orthodontic bracket is attached to the tooth. Following a short healing period, the orthodontist can begin pulling the tooth into its correct position.
