Wisdom teeth are the last molars to come through in the dental arch. They normally appear between the ages of 16 and 21. Because they erupt late, there is often little or no room for them in the mouth, which can leave them trapped beneath the gum, causing pain, swelling or discomfort.

When they do manage to erupt, they may be badly positioned or misaligned. In addition, because these teeth are difficult to clean, infections and other dental problems can arise from the build-up of bacteria.
Wisdom teeth do not have to be extracted in everyone; however, there are situations in which removal is recommended: pericoronitis (inflammation of the tissue covering the tooth); formation of a cyst; extensive decay that is difficult to access or treat; pain; orthodontic reasons; prosthetic reasons.
Once extraction has been recommended by the dentist, treatment should be carried out as soon as possible.
