Wisdom tooth assessment and removal
Not every wisdom tooth needs to be removed.
SHORT ANSWER
Not every wisdom tooth needs to be removed. The decision depends on symptoms, disease, damage to neighbouring teeth, recurrent infection, cystic change, caries, periodontal problems and other clinical findings.
Position alone is not enough: An impacted tooth can remain symptom-free and disease-free. Routine prophylactic removal of healthy, pathology-free impacted wisdom teeth is not supported by NICE guidance.

Position alone is not enough
An impacted tooth can remain symptom-free and disease-free. Routine prophylactic removal of healthy, pathology-free impacted wisdom teeth is not supported by NICE guidance.
Imaging and nerve proximity
Lower wisdom teeth can lie close to the inferior alveolar nerve. Panoramic imaging may show risk indicators; CBCT may be considered when three-dimensional information is expected to change surgical planning.
Coronectomy
In selected high-risk lower wisdom tooth cases, coronectomy may be considered as an alternative to complete removal to reduce the risk of nerve injury. It is not suitable in every case.
Recovery
Pain, swelling and limited mouth opening can occur after surgical removal. Post-operative instructions are tailored to the procedure. Increasing pain after initial improvement, fever or persistent bleeding needs review.
Reasons to remove a wisdom tooth
Removal may be considered for recurrent pericoronitis, caries that cannot be predictably restored, damage to the adjacent tooth, periodontal pathology, cystic change or other disease. A symptom-free tooth without pathology is a different situation.
Nerve-risk discussion
When a lower third molar is close to the inferior alveolar canal, risk assessment may include signs on panoramic imaging and selected use of CBCT. The purpose of CBCT is to clarify anatomy when that information is expected to affect the surgical decision.
Coronectomy is not “half an extraction”
Coronectomy intentionally leaves the roots while removing the crown in selected cases where complete removal may carry higher nerve risk. The retained roots are monitored and can migrate over time.
Questions to ask
- What is the specific indication for removal?
- How close is the tooth to the nerve?
- Is CBCT likely to change the plan?
- Is coronectomy relevant?
- What symptoms after surgery would need urgent review?
Recurrent pericoronitis
Partially erupted lower wisdom teeth can develop repeated inflammation in the surrounding soft tissue. Frequency, severity, tooth position and the ability to maintain the area influence whether removal is recommended.
Adjacent second molar
A wisdom tooth in an unfavourable position can contribute to distal caries or periodontal defects on the neighbouring second molar. The health of that tooth can therefore be an important part of the extraction decision.
Travel after surgery
For an international patient, it is sensible to leave enough time for early review if the case is surgically complex. Do not schedule a long flight immediately after a difficult extraction without discussing timing with the treating dentist.
