Wisdom tooth removal (Surgical removal of third molars (third molar extraction))
A procedure to remove one or more wisdom teeth, usually because they are causing pain, infection or other problems.
✓ Medically reviewed by a GMC-registered consultant · last reviewed September 2026 · next review September 2027 · how we review
In short
- Wisdom teeth are removed for a clear reason — such as infection, decay or cysts — not routinely when healthy and trouble-free.
- Lower wisdom teeth sit near a nerve, so numbness of the lip, chin or tongue is the main specific risk; it is usually temporary.
- Most people recover within a few days to about 2 weeks, with soreness, swelling and jaw stiffness in between.
- If the tooth is very close to the nerve, a coronectomy (leaving the roots) may be safer; a scan may be used to plan this.

What is wisdom tooth removal?
Wisdom teeth are the last molars to come through, usually in the late teens or twenties. There is often not enough room for them, so they can come through at an angle or stay partly buried (impacted). When this causes problems, the tooth may need removing.
Common reasons to remove a wisdom tooth include repeated gum infections around it (pericoronitis), decay that cannot be repaired, infection or abscess, cysts, or damage to the tooth next door. National guidance (NICE) is clear that healthy wisdom teeth that are not causing problems should not be removed routinely, even if they are impacted — the operation has real risks and is only worth it when there is a genuine reason.
Lower wisdom teeth lie close to a nerve that supplies feeling to the lip, chin and tongue, so a key risk is temporary or, less often, lasting numbness or altered sensation. Where the tooth sits very close to this nerve, an alternative called a coronectomy (removing only the crown and leaving the roots) is sometimes safer. The right plan depends on the exact position of your tooth.
Types & techniques
There isn't one single operation. The right approach depends on you — which is something to discuss with your surgeon.
Remove now vs monitor
| Remove | Monitor |
|---|---|
| For a clear problem (pain, infection, decay) | For healthy, trouble-free teeth |
| Stops recurring symptoms | Avoids surgery and its risks |
| Carries nerve and socket risks | Needs ongoing dental review |
| Easier when younger | Problems may still develop later |
| Coronectomy if nerve is very close | Treat individual infections as they arise |
NICE advises against routinely removing healthy, symptom-free wisdom teeth, even if impacted. Removal is for a genuine clinical reason. Where the nerve is very close, a coronectomy may reduce risk compared with full removal.
Preparing for your surgery
- See the dentist or oral surgeon to confirm there is a clear reason to remove the tooth.
- Have any needed X-ray, and a cone-beam CT scan if the tooth looks close to the nerve, to plan the safest approach.
- Discuss the anaesthetic option (local, sedation or general) and the risk of nerve numbness for your tooth.
- Tell the team about medicines (especially blood thinners), bleeding tendencies, and conditions like diabetes.
- If you are having sedation or a general anaesthetic, follow fasting instructions and arrange a lift home.
- Stock up on soft, cool foods and recommended painkillers for the first few days.
- Plan time off to match the difficulty — often 1–2 days, sometimes a little longer.
What happens
Most wisdom teeth are removed under local anaesthetic, so the area is numb but you are awake; sedation or a general anaesthetic may be used for difficult cases, several teeth, very anxious patients or children. A simple extraction can take just a few minutes.
For an impacted tooth, the surgeon lifts the gum, may remove a small amount of bone, and often divides the tooth to remove it in pieces. The socket is cleaned and dissolvable stitches are usually placed. The whole procedure usually takes no more than about 40 minutes. You bite on gauze afterwards to help a clot form, and the team gives you painkilling and aftercare advice before you go.
Is this operation right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Your wisdom teeth are healthy and not causing problems — routine removal is not advised, even if impacted.
- The tooth lies so close to the nerve that full removal carries a high numbness risk, where a coronectomy may be safer.
- An active spreading infection may need treating first before the tooth is removed.
- You are not fit for the sedation or general anaesthetic being considered until other health issues are managed.
Delay surgery if…
- You have an active, spreading mouth infection that needs settling first.
- Your blood-thinning medicine or a bleeding tendency has not been assessed.
- You have poorly controlled diabetes or another condition that needs optimising.
- You are having sedation or a general anaesthetic but cannot arrange a lift home and support.
- You are pregnant — timing and approach should be discussed with your team.
Alternatives to discuss
- Monitoring a symptom-free tooth with regular dental review rather than removing it.
- Treating individual gum infections (pericoronitis) with cleaning, salt-water rinses and antibiotics when truly needed.
- A coronectomy instead of full removal where the nerve is very close.
- Improving cleaning around a partly-erupted tooth where feasible.
- The NHS pathway rather than private care if speed is not the priority.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Anaesthetic choices
The safest option depends on the operation, your health, the facility and your surgeon/anaesthetist. Ask what is planned and why.
Benefits
- Stops recurring pain or gum infections around the tooth
- Removes a tooth that is badly decayed or damaging the tooth next door
- Treats or prevents cysts or other problems linked to the tooth
- Can make oral hygiene easier where a partly-erupted tooth traps food
- Resolves abscesses or repeated swelling caused by the tooth
Risks & complications
- Pain, swelling and bruising for several days
- Jaw stiffness and difficulty opening the mouth fully (often eases over 1–2 weeks)
- Some bleeding or oozing from the socket on the first day
- Difficulty eating and a sore mouth for a few days
- An unpleasant taste or smell while the socket heals
- Dry socket — a painful socket a few days later when the clot is lost, more common with lower teeth and in smokers
- Infection of the socket, sometimes needing antibiotics
- Temporary numbness or tingling of the lip, chin or tongue (after lower teeth)
- Bleeding that needs further attention
- Lasting (permanent) numbness or altered sensation of the lip, chin or tongue
- Damage to a neighbouring tooth or filling
- A small opening into the sinus when removing upper wisdom teeth
- Jaw fracture (very rare)
- Serious problems related to sedation or a general anaesthetic
The most important specific risk is nerve injury after lower wisdom teeth, causing numbness or altered feeling of the lip, chin or tongue. It is usually temporary but can occasionally be permanent, and the risk is higher the closer the tooth sits to the nerve. A scan can show this, and a coronectomy may be safer in high-risk cases. Ask your surgeon how close your tooth is to the nerve, your personal risk, and whether a coronectomy is an option.
Published figures to discuss
Risk depends heavily on how impacted the tooth is and, for lower teeth, how close it lies to the nerve. The figures below are cautious ranges from dental surgical literature and guidance; nerve-injury risk is much higher when the tooth abuts the nerve, which imaging can identify. These are not guarantees for any one person.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Temporary nerve numbness (lip, chin or tongue) after lower teeth | Usually low single figures overall, but higher when roots touch or overlap the nerve canal on imaging | Usually recovers over weeks to months. Risk rises sharply when the tooth sits very close to the nerve. | Coronectomy as an alternative to complete extraction of mandibular third molars with nerve-injury risk (PMC)ncbi.nlm.nih.govSource-linked context |
| Permanent nerve numbness or altered sensation | Rare overall, usually well under 1%; in very high-risk nerve-contact cases, published series report much higher rates | A cone-beam CT scan can identify high-risk teeth; a coronectomy may be considered to reduce this risk. | Coronectomy as an alternative to complete extraction of mandibular third molars with nerve-injury risk (PMC)ncbi.nlm.nih.govPublished figure |
| Dry socket (alveolar osteitis) | Recognised; commonly reported around 2–12% after lower third-molar surgery, higher in smokers and oral-contraceptive users | Tends to occur around days 3–5; painful but treatable. | Coronectomy as an alternative to complete extraction of mandibular third molars with nerve-injury risk (PMC)ncbi.nlm.nih.govPublished figure |
| Coronectomy needing later root removal | A small minority; many reviews report later root removal around 3% or less, while root migration itself is common | Retained roots usually stay quiet but can occasionally migrate or become symptomatic. | Coronectomy as an alternative to complete extraction of mandibular third molars with nerve-injury risk (PMC)ncbi.nlm.nih.govPublished figure |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
Recovery — what to expect, and when
Most people are back to normal activities within a day or two, though soreness, swelling and jaw stiffness can last up to about 2 weeks, especially after a difficult removal.
- Pain, swelling and bruising of the cheek and jaw for several days
- Jaw stiffness and limited mouth opening that eases over 1–2 weeks
- Some oozing of blood from the socket on the first day
- A bad taste or smell while the socket heals
- A tender, healing socket that gradually closes over
Aftercare
- For the first 24 hours, avoid rinsing, spitting, hot drinks, alcohol and smoking to protect the clot.
- From the day after, rinse gently with warm salt water after meals to keep the area clean.
- Take painkillers as advised; avoid disturbing the socket with your tongue or fingers.
- Eat soft, cool foods and chew on the other side at first.
- Use cool packs on the cheek to ease swelling in the first day or two.
- Do not smoke, as it raises the risk of dry socket and slows healing.
- Rest and avoid strenuous activity for the first day or two.
- Know the signs of dry socket and infection, and who to contact.
- Recommended painkillers in stock
- Soft, cool foods and drinks ready
- Gauze for any bleeding and salt for salt-water rinses
- A lift home arranged if having sedation or a general anaesthetic
- 1–2 days off work or school booked
- Cool packs for swelling
- The dental team's contact number saved for problems
Scars and how they heal
Wisdom tooth removal is done inside the mouth, so there is no scar on the face. The gum over the socket heals over the following weeks. Stitches are usually dissolvable.
⚠ Get urgent help if…
- Bleeding that does not stop after biting on gauze for 20–30 minutes
- Severe or increasing pain a few days later, often with a bad taste (possible dry socket)
- Spreading swelling, redness, pus, or a high temperature (possible infection)
- Difficulty swallowing or breathing, or swelling spreading to the eye or neck (urgent — call 999)
- Numbness of the lip, chin or tongue that is not improving
- Feeling generally very unwell with a fever
Who to contact: your surgeon or clinic first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your surgeon gives you.
Results & realistic expectations
Removing a problem wisdom tooth usually stops the pain or infection it was causing and prevents further problems from that tooth. Most people heal within about two weeks.
It is surgery with real risks, so it is only worthwhile when there is a clear reason. After lower teeth, any numbness of the lip, chin or tongue is usually temporary, but a small number of people have lasting changes in sensation. A good surgeon assesses how close the tooth is to the nerve and discusses the safest approach, including whether a coronectomy is better for you.
Once a wisdom tooth is removed, it does not grow back, so the problem it caused is resolved for good. After a coronectomy, the retained roots usually stay quiet, but a small number migrate or become troublesome and need removing later. Looking after your remaining teeth and gums helps avoid problems elsewhere.
Combining with other procedures
Sometimes more than one wisdom tooth is removed in the same visit, particularly under sedation or a general anaesthetic, to avoid repeated procedures. The risks and recovery are greater when several are done together, so this should be a considered decision, not just for convenience.
Follow-up & long-term care
Many simple extractions need no routine review, but you should be told who to contact and when, and have any stitches removed if they are not dissolvable. After a lower tooth, any nerve numbness should be reviewed and monitored. After a coronectomy, the retained roots may be checked over time. You should have a clear route back for dry socket, infection or persistent numbness.
- Keep up good oral hygiene and regular dental check-ups.
- Report any lasting numbness of the lip, chin or tongue so it can be monitored.
- After a coronectomy, attend any reviews of the retained roots.
- Avoid smoking, which harms healing and gum health.
Revision and secondary surgery reality
- An extracted wisdom tooth does not regrow, so re-treatment for that tooth is not usually needed.
- After a coronectomy, a small number of people need the retained roots removed later.
- Dry socket may need the socket cleaned and a dressing placed, sometimes more than once.
- Persistent numbness occasionally needs specialist assessment and monitoring.
Ask your surgeon for their own revision rate, what counts as a revision, and what is included in the written aftercare policy.
What good aftercare looks like
- Clear written advice on protecting the clot, salt-water rinses, pain relief and soft diet.
- Specific warning signs for dry socket and infection, with a named contact and out-of-hours route.
- Review and monitoring of any nerve numbness after lower teeth.
- Follow-up of retained roots after a coronectomy.
- Honest discussion beforehand of personal nerve-injury risk and the safest approach.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Whether the tooth is simple to remove or impacted and surgical
- How many teeth are removed
- The anaesthetic chosen (local, sedation or general)
- Whether a scan (such as cone-beam CT) is needed to plan around the nerve
- The surgeon's or dentist's fee and the facility fee
- Follow-up appointments and the policy if a complication occurs
- The surgeon's or dentist's fee and any facility fee
- The anaesthetic option included (local, sedation or general) and any extra cost
- Any imaging needed, such as an X-ray or cone-beam CT scan
- How many teeth are covered by the quote
- Follow-up appointments and stitch removal if needed
- The cancellation policy
- What happens, and who pays, if a complication such as dry socket, infection or lasting numbness occurs
On the NHS? Wisdom tooth removal is available on the NHS when there is a clear clinical reason; healthy, symptom-free teeth are not routinely removed, and private care may be used for speed, choice or sedation options.

Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Recommending removal of healthy, symptom-free wisdom teeth against NICE guidance.
- Nerve-injury risk for lower teeth not being clearly explained, or no scan where the nerve looks close.
- Coronectomy not being offered or discussed in high-risk cases.
- Dry socket and its warning signs not being explained.
- No written aftercare plan or contact route for problems.
Marketing red flags
- Encouraging removal of healthy wisdom teeth 'just in case'.
- Describing the procedure as 'quick and without risks' without mentioning nerve injury or dry socket.
- Bundling several extractions under general anaesthetic without a clear clinical reason.
- No discussion of monitoring, coronectomy or what happens if a complication occurs.
Choosing a surgeon safely
- Check your surgeon is on the GMC Specialist Register for this area.
- Make sure they practise at a CQC-registered location, and look for membership of bodies like BAAPS or BAPRAS.
- You're entitled to a two-stage consent process with time to reflect (a cooling-off period). The surgeon who will operate must consent you — not a salesperson.
- Be wary of pressure: time-limited offers, discounts or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including aftercare and any revision — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good surgeon will welcome every one of these.
- Is there a clear reason to remove this tooth, or could it be monitored?
- How close is my lower tooth to the nerve, and what is my risk of numbness?
- Do I need a scan (cone-beam CT) to plan the safest approach?
- Is a coronectomy a safer option in my case?
- What anaesthetic do you recommend, and why?
- Exactly what should I do, and who do I call, if I get dry socket or lasting numbness?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the surgeon who carries out my operation, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this operation not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
