What to know about third molar removal

Third molar removal, commonly known as wisdom tooth extraction, is a routine dental procedure performed when wisdom teeth cause problems or are likely to do so in the future. Wisdom teeth are the final set of molars to develop and usually appear between the late teens and mid-twenties. Because there is often insufficient space in the jaw, they may become impacted, erupt at an angle, or remain partially covered by gum tissue.


A dentist or oral surgeon may recommend removal if a wisdom tooth causes recurrent pain, infection, gum inflammation, tooth decay, damage to neighbouring teeth, cyst formation, or difficulty maintaining good oral hygiene. In some cases, removal may also be considered when an impacted tooth has a high risk of causing future problems.


Before the procedure, the dentist will assess the tooth clinically and usually take dental X-rays to determine its position and relationship to surrounding structures. Depending on the complexity of the extraction and the patient's preferences, the procedure may be carried out using local anaesthetic, sedation, or, less commonly, general anaesthesia.


After removal, some pain, swelling, bruising, and difficulty opening the mouth are normal. These symptoms are generally most noticeable during the first few days and gradually improve. Patients are usually advised to rest, follow their dentist's instructions, maintain careful oral hygiene, and avoid smoking and vigorous rinsing during the initial healing period. Soft foods and appropriate pain relief can also make recovery more comfortable.


Although complications are uncommon, they can include infection, prolonged bleeding, dry socket, or temporary nerve disturbance, particularly with lower wisdom teeth positioned close to important nerves. Patients should contact their dentist if they develop worsening pain, persistent bleeding, significant swelling, fever, or other concerning symptoms.


Overall, third molar removal is a well-established procedure that can prevent or treat problems associated with problematic wisdom teeth. A dental assessment can determine whether removal is appropriate based on the tooth's position, symptoms, and potential risks.
