Dental Implant Glossary Impaction A tooth that is "stuck", or can grow no further into the mouth.  Usually referrs to wisdom teeth,                      but any tooth can be impacted under unusual circumstances.  Extra, or supernumery teeth, are                      often impacted.  Impacted wisdom teeth have an incidence of cyst or tumor formation of around                      one to five percent.  Partially impacted wisdom teeth (half in-half out) have a very high rate of                      periodontal (gum) infections.  Additionally, pressure from impacted teeth can often cause damage                      to nearby teeth.
