What is impacted tooth?

Impacted tooth is the tooth that fails to erupt. Normally the third molars are frequently impacted. These teeth erupt at the age 18-20 year.

The impaction of third molars is caused from the length of alveolar arch smaller than the tooth arch (mesiodistal width of each tooth). Some hypothesis claims that the evolution of human’s jaw make the jaw smaller.

In some patients, third molars can fully erupt. However, they are recommended to have them extracted due to possible caries, gum swelling and difficult to clean.
