What's considered an impacted tooth?

Unerupted tooth: An impacted tooth is one that does not fully erupt into the mouth. This may be related to inadequate space for the tooth, the position the tooth is developing, and/or something that is obstructing the path of eruption of the tooth.

Anything under bone: An impacted tooth is any tooth that has its crown (the top part that you see) under bone. If it is partially impacted than only part of it is under bone, if it is fully impacted it is fully under bone (none of these descriptions tell us how thick the bone is covering the tooth).

Blocked eruption: Actually, a tooth can be considered to be impacted if it has normal exposure out of bone, but is covered partly, or, completely by soft gum tissue.

A tooth that has not: Had the opportunity to reach full eruption (normal position) into the dental arch. There can be soft tissue implication (d7220), partial bony impaction (d7230) and complete bony impaction (d7240). Any tooth can demonstrate impaction. Wisdom teeth and canines tend to be the most frequently impacted.

See orthodontist: An impacted tooth means that something is preventing the path of eruption of the tooth into the mouth. typically this requires oral surgery to either remove the tooth to expose it for an orthodontist to move it into place

By definition: an impacted tooth is a tooth that gets blocked as it is pushing through the gum into your mouth. Wisdom teeth often are impacted.

Impacted tooth: An impacted tooth is one that is partially or fully blocked from eruption. As there is a 1 in 7 chance of problems occurring around an impacted tooth, treatment is usually indicated. To deimpact the tooth may require extraction or Orthodontic treatment.
