Impacted tooth (impaction)

An unerupted or partially erupted tooth so positioned that complete eruption is unlikely.

A tooth which is held against another tooth and so cannot grow normally.

A tooth blocked from appearing in the mouth because the jaw is already overcrowded with teeth. An impacted tooth can become infected and painful, requiring extraction; it can also damage other teeth or cause the opposite tooth to grow abnormally long.

Tooth, usually a wisdom tooth, so firmly wedged in the socket that it cannot break through the gum.

A tooth unable to erupt due to crowding by adjacent teeth, malposition of the tooth, or developmental disturbances.

A tooth that is developing in a position where it is in conflict with another tooth, bone, or soft tissue.
