Wisdom tooth removal: what to ask before you agree

Wisdom teeth are the last teeth to come through, usually at the back of the mouth. Many people keep theirs for life. The NHS says they are removed when they cause problems, not just because they exist. Whether yours need to come out is for a licensed dentist to say after an exam and an X-ray.

Why might a dentist suggest removal?

General reasons include a tooth that is stuck under the gum, that comes through at an angle, that keeps getting infected, or that damages a neighbouring tooth. Pain at the back of the mouth has many causes, so do not guess. See a dentist.

The decision rule is simple: no problem, no rush. Ask what the specific problem is and what happens if you wait.

What questions should I ask?

Questions to ask your clinic

1. What problem do you see, and can I see it on the X-ray?
2. What could happen if I leave it for now?
3. Is there anything else we could try first?
4. Who will remove it, and how many do they do?
5. Will I have local anaesthetic only, or sedation or general anaesthetic? Why?
6. What are the risks for my teeth, and what are the usual short-term effects?
7. What does the fee cover, and what is extra?
8. Who do I call if there is a problem after?

Ruling: if the answer to question 1 is vague, ask for a second view before you book.

Who should do it?

Simple removals are often done by a general dentist. Harder ones may be referred to an oral surgeon, which is a dentist with extra training in surgery of the mouth. Ask which applies to you and why. If sedation or a general anaesthetic is planned, ask who provides it and how you will be monitored. Our page on checking a practitioner shows how to confirm a licence.

What to expect

• Before: an exam and X-ray, a talk about options, consent, and a plan for the day. Ask about eating, driving and who should come with you.
• At the visit: numbing or sedation, then removal. Time varies with the tooth.
• After: the NHS describes some pain, swelling and bruising for a few days as typical, with advice on rinsing, eating and avoiding smoking. Ask your clinic for its written aftercare and follow it.

Your clinic should tell you which signs mean you must call: bleeding that will not stop, severe or growing pain, fever, a bad taste, or swelling that spreads. Trouble breathing or swallowing needs urgent medical care.

Red flags

• You are told to remove all four at once with no reason given
• No exam or X-ray is mentioned
• The sedation plan is vague
• There is no clear person to call after
• A price is quoted but nothing is written

Is it worth asking about costs first?

Yes. A quote should say what is included: the exam, X-ray, anaesthetic, the procedure, and a review visit. Read our guide on reading a treatment quote before you pay. Removal often costs more as it gets harder, and the dentist can tell you why.

Common mistakes

• Agreeing to sedation without asking who monitors you
• Not arranging a lift home
• Skipping the written aftercare
• Not asking who to call out of hours
