Impacted Wisdom Tooth Removal: When It Is Needed and What Follows

When a Wisdom Tooth Needs to Come Out

Wisdom teeth usually start coming through in the teens or early twenties, but can cause problems at any age. The NHS is clear about the threshold: a wisdom tooth is removed because it is causing problems. If it is not causing problems, the tooth is usually left where it is and monitored at your routine dental check-ups.

Removal may be needed where there is not enough space for the tooth to come through fully — for example when it is blocked by another tooth, which is what *impacted* means, or partly covered by the gum. A dentist may take X-rays to check how the teeth are positioned.

An impacted wisdom tooth is not in itself a reason for surgery. Whether to monitor or remove is a clinical judgement made from your symptoms and the position of the tooth, not from the word on a report.

Imaging

X-rays are used to check position. A three-dimensional scan is not required for every case; it may be considered where a two-dimensional image raises a suspicion of a close relationship with the nerve and the extra information would change the treatment choice. Our imaging article explains how that decision is made.

The Procedure

An injection numbs the gum so you should not feel pain. Sedation may be used to help you feel relaxed, or a general anaesthetic where you are asleep — the NHS notes these are only needed if the teeth are more difficult to remove or you are anxious.

The surgeon cuts the gum if it is covering the tooth, widens the socket, and removes the tooth either in one piece or cut into two or three pieces. The gum is stitched if necessary with dissolvable stitches. The NHS describes this as often taking just a few minutes and no more than 40 minutes. You usually go home the same day; after a general anaesthetic you might need to stay overnight.

A dentist may be able to remove wisdom teeth, or may refer you to a specialist. Our impacted tooth extraction page sets out the general approach.

Recovery

The NHS describes the first two weeks: some pain and swelling that should start to improve after one or two days, possible bruising on the cheek, and chewing and swallowing that may be uncomfortable. Stitches dissolve by themselves, and a blood clot forms over the wound which helps it heal.

You are given specific advice for the first few days, and that written instruction is what you follow. The general shape of it is soft or liquid food until chewing is comfortable, keeping the wound clean by rinsing gently, cleaning your other teeth carefully while avoiding the affected area so the stitches and clot are not disturbed, and pressing the area for at least 10 minutes with a clean cloth if bleeding occurs.

Things to avoid: hard or crunchy food and anything that could lodge in the wound such as nuts or seeds; smoking, which increases the risk of infection; and alcohol or very hot drinks, which raise the risk of bleeding or scalding. After a general anaesthetic do not drive for 48 hours, or for 24 hours after a sedative injection.

Most people can return to normal activities the day after. If the teeth were more difficult to remove, or you had a general anaesthetic, one to three days off work may be needed.

Risks

The NHS lists the complications that can happen, and your surgeon should explain them before the procedure:

• Dry socket — a painful condition where the blood clot over the socket does not form properly or is dislodged before the gum has healed.

• Infection, which may need treating with antibiotics.

• Damage to nerves close to the tooth, causing numbness or tingling in the tongue, lips and chin. This usually gets better but can last a few weeks or months.

Coronectomy

Where a lower wisdom tooth lies very close to the nerve, removing only the crown and deliberately leaving the roots — a coronectomy — may be discussed as an alternative to full removal, with its own follow-up requirements. It is not suitable in every case, and it is a decision made after imaging and examination rather than requested in advance.

When to Get Help Urgently

The NHS advises asking for an urgent dentist appointment or seeking help if you have bleeding that does not stop; pain and swelling that is severe or getting worse and painkillers are not helping; or pain with a bad taste in your mouth, a high temperature or feeling unwell.

If you have difficulty breathing or swallowing, or rapidly spreading swelling of the face or neck, do not wait for a reply to a message — call the emergency number or go to an emergency department.

Does an Extracted Wisdom Tooth Need Replacing?

Usually not. A wisdom tooth is at the very back of the arch and its loss does not normally leave a gap that needs an implant or a bridge. Replacement is considered on the merits of your own bite rather than as a routine follow-on.

Frequently Asked Questions

Should I have healthy wisdom teeth out preventively?

Not as a rule. The NHS position is that a tooth not causing problems is usually left and monitored at routine check-ups.

Will I be asleep?

Usually not. An injection numbs the area; sedation or a general anaesthetic are used only where removal is more difficult or you are anxious.

How long will I be off work?

Usually you can return to normal activities the next day; one to three days may be needed for a more difficult removal or after a general anaesthetic.

Is numbness afterwards permanent?

Nerve damage causing numbness or tingling in the tongue, lips or chin usually gets better, though the NHS notes it can last a few weeks or months. Report it rather than waiting it out alone.
