Wisdom teeth may erupt normally, remain partly covered by gum or become impacted. Their position alone does not tell the whole story: symptoms, disease and effects on neighbouring teeth matter.
Recurrent inflammation, decay, infection or other pathology can make removal appropriate. Teeth without problems may instead be monitored. A dentist may use imaging to understand the position and nearby anatomy.
Before surgery, discuss anaesthesia, expected recovery and risks. Lower wisdom teeth can lie close to nerves involved in sensation. Upper teeth may be close to the sinus. Your clinician should explain the significance for your particular case.
After treatment, contact the team if bleeding will not settle, swelling worsens or pain becomes severe. Do not book surgery solely because an advertisement says everyone should remove all wisdom teeth. The decision should follow examination and an explanation of the alternatives.
