Wisdom Tooth Extraction
What Is an Erupted Wisdom Tooth?
A wisdom tooth (20, third molar) is the last molar that has erupted or is partially visible in the mouth. This page covers extraction of wisdom teeth (20) that are accessible inside the mouth, not impacted wisdom teeth (20). Impacted cases require separate surgical planning.
Not every erupted wisdom tooth (20) has to be removed. Teeth that are asymptomatic, can be kept clean and do not harm neighbouring teeth may be monitored. The condition can be followed with periodic examination and panoramic imaging. The extraction decision is made by assessing examination findings and patient complaints together.
Extraction Indications
Extraction may be considered for reasons such as recurrent pericoronitis, decay, crowding, orthodontic planning or pressure on a neighbouring tooth. A panoramic film shows root number, shape and relation to adjacent structures. If there is active infection, extraction may be postponed. In partially erupted wisdom teeth (20), a gum pocket may be prone to infection; hygiene difficulty may support the extraction decision. In an orthodontic plan, extraction may be recommended to address crowding.
Extraction Day
Most erupted wisdom teeth (20) are extracted under local anaesthesia; a surgical approach may be needed if root morphology is complex. Procedure duration depends on the number of teeth. Anticoagulant use should be reported beforehand. A separate assessment is made for patients who want sedation. Extraction of more than one wisdom tooth (20) in the same session may be possible.
Fasting instructions before extraction are given if sedation is planned; they are generally not needed for routine extraction under local anaesthesia. After the procedure, gauze supports clot formation. Extraction of more than one wisdom tooth (20) in the same session may be possible and is planned by clinician and patient decision. Panoramic film assessment before extraction is recommended.
Healing
Cold compresses and soft foods may be recommended in the first 24 hours. Smoking and straw use may increase the risk of alveolitis. Mild swelling and limited mouth opening may last a few days. If sutures are present, a review visit is planned. Antibiotics are not given routinely in every case; systemic risk factors are assessed when present. Mouth-rinse use after extraction is planned according to the clinician’s instructions.
Prescription or over-the-counter medication advice is shared for pain control. The clinic should be contacted in case of marked pain, fever or bleeding beyond expectations. Return-to-work timing depends on the physical intensity of the job; most patients can return to daily activities within a few days. Following oral hygiene instructions during the first week is recommended.
