Most wisdom teeth do not need to be removed. Current UK guidance is clear on this: if a wisdom tooth is healthy and causing no problems, leaving it alone is usually the right decision. Removal is recommended when a tooth is causing repeated infection, decay that cannot be restored, or damage to the neighbouring tooth. This guide explains how that judgement is made, what the warning signs look like, and what happens if a tooth does need to come out.
What wisdom teeth are, and why they cause trouble
Wisdom teeth are the third molars at the very back of the mouth. They usually appear between the ages of 17 and 25, long after the rest of the adult teeth have settled into place. That late arrival is the root of the problem. By the time they push through, there is often not enough room left in the jaw, so the tooth comes through at an angle, only partly emerges, or stays buried in the bone. A tooth in that position is called impacted.
Impaction is not automatically a reason for removal. Plenty of people have impacted wisdom teeth that sit quietly for decades and never cause a day of bother. What matters is whether the tooth is causing harm, or is very likely to.
Signs your wisdom tooth may need attention
Some discomfort as a wisdom tooth breaks through is normal and usually settles within a few days. The signs below are worth having looked at rather than waiting out:
Swollen, red or painful gum over a partly emerged tooth, especially if it keeps coming back
A bad taste or persistent bad breath coming from the back of the mouth
Difficulty opening your jaw fully, or pain on chewing
Food packing repeatedly between the wisdom tooth and the tooth in front
Decay you can see or feel in the wisdom tooth or its neighbour
Facial swelling, or pain with fever — this needs same-day attention
The recurring gum infection in that list has a name: pericoronitis. It happens when a flap of gum partly covers the tooth and traps bacteria and food underneath. A single mild episode can often be settled with careful cleaning and, occasionally, antibiotics. Repeated episodes are one of the most common reasons a wisdom tooth is eventually removed.
Why the tooth in front matters most
The strongest argument for removing a wisdom tooth is often not about the wisdom tooth at all. When a wisdom tooth leans into the second molar, it creates a trap that is almost impossible to clean. Decay then develops on the back surface of that second molar, which is a far more useful tooth. Treating decay in that position is difficult, and in the worst cases the second molar is lost as well.
This is why X-rays matter. An angled wisdom tooth pressing against its neighbour is a reason to act early, before the damage is done, even if nothing hurts yet.
When leaving it alone is the better decision
Removing a healthy, symptom-free wisdom tooth carries risk and recovery time for no clear benefit, which is why it is not recommended. A wisdom tooth can usually stay where it is when it has come through straight and in a useful position, when you can clean around it properly, and when there is no decay or gum problem. Fully buried teeth causing no symptoms are also generally left, though we will keep an eye on them at your routine check-ups.
What removal involves
A straightforward upper wisdom tooth in a good position is often a quick procedure under local anaesthetic, not very different from any other extraction. A lower tooth that is impacted or lying at an angle is more involved: it may need a small incision in the gum, and the tooth is sometimes sectioned into pieces so it can be removed through a smaller opening. Local anaesthetic means you should feel pressure but not pain.
Some cases are better handled in a specialist oral surgery setting, particularly where the roots sit close to the nerve in the lower jaw. If that applies to you, we will explain why and arrange the referral rather than proceed.
Recovery, and what helps
Expect some swelling and soreness for two to three days after a surgical removal, easing over the following week. Simple extractions usually settle faster. These steps make a real difference:
Keep the area clean with warm salt-water rinses from the day after — gently, not vigorously
Avoid smoking and vaping, which meaningfully increase the risk of a painful dry socket
Stick to softer food for a few days and chew on the other side
Take pain relief as advised, before the anaesthetic fully wears off
Avoid strenuous exercise for the first 24 hours
Contact us if pain worsens rather than improves after day three, if you develop a fever, or if bleeding does not settle with gentle pressure. A dry socket is uncomfortable but easily treated, and it is better dealt with quickly.
What it costs
Wisdom tooth removal is priced case by case, because a straightforward upper extraction and a surgical lower impaction are genuinely different procedures. We assess the tooth, take the X-rays needed, and give you a written cost before anything is agreed. If you are registered on one of our membership plans, a discount applies to selected treatments. Where a wisdom tooth is causing acute pain or swelling, our emergency dental care is the fastest route to getting seen.
FAQ
Q: Do all wisdom teeth have to be removed? A: No. UK guidance advises against removing healthy wisdom teeth that are causing no problems. Removal is recommended for repeated infection, decay that cannot be restored, or damage to the tooth in front.
Q: How long does recovery from wisdom tooth removal take? A: Swelling and soreness usually peak at two to three days and ease over the following week. Simple extractions often settle more quickly than surgical ones.
Q: Is wisdom tooth removal painful? A: The procedure is done under local anaesthetic, so you should feel pressure but not pain. Discomfort afterwards is normal and is usually managed well with ordinary pain relief.
Q: Can I keep a wisdom tooth that is impacted? A: Often yes. Impaction alone is not a reason to remove a tooth. It is removed when it causes symptoms, decay, or harm to the neighbouring molar.
Q: Where can I get wisdom teeth checked in Nottingham? A: Pear Tree Dental in Burton Joyce assesses wisdom teeth with X-rays and gives you a clear recommendation. Call 0115 931 2935 to arrange an appointment.
