Wisdom teeth are the last molars at the back of the mouth. Some erupt normally and remain healthy; others become partially erupted, trapped under the gum or angled against the tooth in front. Removal is not automatic—the decision depends on symptoms, disease risk and imaging.
Signs that need assessment
Seek a dental examination if you have recurring pain behind the last molar, swelling, difficulty opening your mouth, food trapping, bad taste, gum infection or decay near a wisdom tooth. Facial swelling, fever, trouble swallowing or breathing requires urgent medical or dental attention.
How is the tooth evaluated?
The dentist or oral surgeon reviews your medical history and examines the area. A panoramic X-ray is commonly used to assess the tooth’s angle, roots and nearby structures. CBCT imaging may be considered when a lower wisdom tooth appears close to an important nerve.
What happens during removal?
Simple extractions may be possible when the tooth has erupted. Impacted teeth can require a small incision, removal of surrounding bone or division of the tooth into sections. Local anaesthesia is commonly used. The surgeon should explain anaesthesia choices, risks and expected recovery for your case.
Recovery and aftercare
Some swelling and discomfort are expected after surgery and often peak during the first few days. Follow the prescribed instructions, avoid smoking, do not disturb the blood clot and eat suitable foods. Contact the clinic if bleeding does not settle, pain suddenly worsens after initial improvement, swelling continues to increase, or you develop fever, numbness or difficulty breathing.
Should a symptom-free wisdom tooth be removed?
Not always. Some can be monitored with examinations and imaging. Removal may be recommended when there is recurrent infection, decay that cannot be restored, damage to the neighbouring tooth, a cyst or another clear clinical reason.
