When an impacted wisdom tooth starts to erupt through the gum, an infection can start around the top of the tooth. Infection and inflammation (swollen, red gums) can cause pain, swelling and jaw stiffness.
A wisdom tooth may push nearby teeth out of their correct position.
Pressure from the wisdom tooth may cause pain in the neighbouring tooth.
If a wisdom tooth is not removed, a fluid sac called a cyst can form around the tooth and can damage bone, other teeth and the gums.
An upper wisdom tooth may push sideways out of the gum and can cause a cheek ulcer when it rubs against it.
- Food Trap
Food becomes trapped between the wisdom tooth, and the tooth next door and can cause cavities in both teeth.
