Teeth Extraction/ Impaction


An impacted tooth is a tooth that has not erupted (emerged fully into the oral cavity).

Types:

Partially surrounded by bone (partial bony impaction)

Only surrounded by soft gum tissue (a soft tissue impaction)

Traditionally, the term impacted teeth usually refer to the wisdom teeth (the third molars, the teeth furthest back in the mouth).

Many times if they appear to be causing no problems for the patient, they are left alone. If they are positioned in a fashion that they appear to be pushing up against the roots of the second molars (the next teeth forward) or if they are causing periodontal (gum) problems, they will need to be removed. While most general dentists are comfortable removing teeth, patients with impacted teeth are usually referred to a specialist (oral surgeon) for their removal.
