When Wisdom Teeth Need Removing — and When They Do Not
UK guidance changed in the early 2000s: healthy asymptomatic wisdom teeth are now monitored, not extracted prophylactically. Dr. Cansu Öztürk explains the genuine indications for removal, the procedure, and the risks we discuss before any consent.
Why wisdom teeth cause problems
Modern human jaws are smaller than they were 500 years ago, and the wisdom teeth (third molars) are the last to erupt — typically between ages 17 and 25 — into a mouth that has often run out of space. The result: partial eruption (a flap of gum over part of the tooth), full impaction (still buried in bone), or eruption at an angle that traps food against the second molar.
Indications for removal
UK guidelines (NICE, RCS Faculty of Dental Surgery) restrict wisdom tooth removal to documented pathology:
- Recurrent pericoronitis — gum infection around a partially-erupted tooth, two or more episodes.
- Untreatable decay on the wisdom tooth or adjacent second molar.
- Cyst formation — dentigerous or other odontogenic cysts.
- Periodontal damage to the second molar from poor cleaning access.
- External resorption of the second molar root.
- Orthodontic interference in selected cases.
When NOT to remove
Asymptomatic, disease-free wisdom teeth do not need removal “just in case.” The 1990s prophylactic-extraction culture has been replaced by evidence-based watchful monitoring with annual X-ray review. We will not extract healthy teeth on demand.
Diagnosis and planning
We use panoramic X-ray as the primary screening image and CBCT when the lower wisdom tooth roots appear in close relationship to the inferior alveolar nerve. CBCT shows the 3D relationship between root and nerve canal — essential for safe surgical planning and patient consent. The CBCT is included in our surgical fee, not extra.
The procedure
Under local anaesthesia (or sedation if requested):
- Gum flap reflected to expose the impacted tooth.
- Bone removed conservatively if needed — minimum to allow tooth retrieval.
- Tooth sectioned with a high-speed handpiece into pieces small enough to remove without forcing.
- Pieces elevated and removed.
- Socket irrigated with saline.
- Sutures placed — usually resorbable.
Total time: 20–45 minutes per tooth.
Recovery and aftercare
The first 24 hours: bite firmly on gauze for 30 minutes after surgery, ice pack to the jaw 20 minutes on/off, soft cool food, no rinsing. Days 2–7: warm salt-water rinses 4× daily, soft food, paracetamol/ibuprofen as needed, chlorhexidine gel on the wound. Avoid smoking, alcohol, and heavy exercise for 7 days. Smoking quadruples dry-socket risk.
What we tell every patient before consent
Risks: dry socket (2–5% of routine, up to 30% of impacted lowers in smokers), nerve numbness (temporary 1–5%, permanent <1% for lower wisdom teeth), infection (1–2%), prolonged bleeding (rare). We discuss each before the patient signs consent. We do not minimise risks to secure the booking. Read more on wisdom tooth removal at GC Clinic.
Frequently asked questions
Should I remove healthy wisdom teeth as a precaution?
NICE guidance and most modern oral surgery opinion is to NOT remove asymptomatic, disease-free wisdom teeth prophylactically. Removal is indicated when there is documented pathology: recurrent infection, decay, cyst, periodontal damage, or orthodontic interference. Routine extraction of healthy impacted teeth was abandoned in the UK around 2000.
How painful is wisdom tooth removal?
The procedure itself is painless under local anaesthesia. Post-operative discomfort peaks at 24–48 hours and resolves over 5–10 days. Most patients manage with paracetamol and ibuprofen. Severe pain after 72 hours suggests dry socket or infection — rare but treatable.
How long is recovery from impacted wisdom tooth surgery?
Soft food for 3–5 days, normal eating by day 7–10. Most office workers return to work after 2–3 days. Sutures, if non-resorbable, come out at day 7. Full bone healing takes 2–3 months but you do not feel this. Avoid heavy exercise for 7 days.
Can I get all four wisdom teeth removed at once?
Yes, often under sedation or general anaesthesia. The trade-off: longer recovery period (5–7 days of restricted eating) but only one surgery. We assess case-by-case based on impaction depth, nerve proximity, and patient preference. Single-side removal is also valid if symptoms are unilateral.
What is the risk of nerve damage?
For lower wisdom teeth close to the inferior alveolar nerve, temporary numbness affects 1–5% of cases and resolves over 6–24 months. Permanent numbness affects less than 1%. We use CBCT planning when nerves are close — guesswork is not acceptable. Coronectomy (removing only the crown of the tooth, leaving roots near the nerve) is an alternative for high-risk cases.
