Wisdom Teeth Removal in London: Cost, Procedure and Recovery

Wisdom teeth — the third molars at the back of the mouth — are among the most commonly extracted teeth in adults. They typically emerge between the ages of 17 and 25, often in a mouth that does not have enough space to accommodate them. When they cause pain, infection or damage to neighbouring teeth, removal is usually the recommended course of action. But not every wisdom tooth needs to come out, and understanding when removal is and is not necessary is an important part of making the right decision. This guide covers when wisdom teeth should be removed, what the procedure involves, the difference between simple and surgical extraction, what it costs at DentAkademi London and what to expect during recovery.

When Do Wisdom Teeth Need to Be Removed?

Wisdom teeth do not always need to be removed. The decision to extract should be based on clear clinical reasons — not routine or preventive removal without evidence of a problem. Extraction is generally recommended in the following situations:

• The tooth is impacted — partially or fully trapped beneath the gum or bone — and causing pain, swelling or infection
• Pericoronitis — repeated infection of the gum flap over a partially erupted wisdom tooth
• Damage to the adjacent second molar — from pressure, decay or root resorption caused by the wisdom tooth
• A cyst or other pathology has developed around the impacted tooth
• The tooth has erupted in a position that makes it impossible to clean effectively, leading to repeated decay
• The tooth is contributing to crowding or bite problems, particularly before or during orthodontic treatment

When Can Wisdom Teeth Be Left Alone?

A wisdom tooth that has fully erupted, is in a functional position, can be cleaned effectively and is not causing problems to neighbouring teeth or the surrounding tissues does not routinely need to be removed. Monitoring at regular dental check-ups is appropriate for wisdom teeth that are present but asymptomatic. Removal carries risks — including nerve injury in some cases — and should only be recommended when the benefits clearly outweigh those risks.

Signs That Your Wisdom Teeth May Need Assessment

• Pain or aching at the back of the jaw, particularly when chewing
• Swelling, redness or tenderness in the gum behind the last molar
• Difficulty fully opening the mouth
• Bad taste or bad breath related to the wisdom tooth area
• Swollen lymph nodes under the jaw or in the neck
• Recurring infection or pain in the same area

These symptoms do not automatically mean extraction is necessary, but they do mean a clinical assessment is needed. An X-ray — and in some cases a CT scan — is usually required to assess the position of the wisdom tooth and its relationship to nearby structures before any decision is made.

Simple vs Surgical Wisdom Tooth Removal

Simple Extraction

A simple extraction is performed when the wisdom tooth has fully erupted above the gumline and can be removed in one piece using forceps under local anaesthesia. At DentAkademi London, simple tooth extraction starts from £250. Recovery is typically straightforward, with discomfort settling within a few days.

Surgical Extraction

Surgical extraction is needed when the wisdom tooth is impacted — partially or fully beneath the gum or bone. The procedure involves making a small incision in the gum, removing bone if necessary and sometimes dividing the tooth into sections before removal. At DentAkademi London, surgical extraction starts from £350. Recovery takes a little longer, and swelling is typically more pronounced in the first few days. A CT scan (from £150 to £250) may be recommended before surgical extraction in cases where the wisdom tooth is close to the inferior alveolar nerve — the main nerve in the lower jaw. This allows the surgeon to plan the procedure with greater precision and reduce the risk of nerve injury.

Wisdom Tooth Removal Under Sedation or General Anaesthesia

Wisdom tooth removal is usually carried out under local anaesthesia in a dental chair. For patients who are anxious, or for complex cases involving multiple impacted teeth, sedation or general anaesthesia may be available. General anaesthesia for dental procedures is offered at DentAkademi London — pricing is provided on application at the consultation. This should be discussed in advance so that appropriate arrangements can be made.

The Procedure: What to Expect on the Day

Before the procedure, the area is numbed with local anaesthetic. Once the tooth and surrounding tissues are fully numb, the extraction begins. For a simple removal, the tooth is loosened and lifted from the socket. For a surgical extraction, the gum is opened, bone may be removed and the tooth may be sectioned. The socket is then cleaned and the gum closed with dissolvable stitches if needed. Most patients feel pressure during the procedure but not sharp pain. If at any point the anaesthetic feels insufficient, more can be administered — patients should always communicate this during the procedure rather than endure discomfort in silence.

Recovery After Wisdom Tooth Removal

Swelling and discomfort are normal after wisdom tooth removal and are most pronounced in the first 48 to 72 hours. Swelling often peaks around the second day before gradually settling. Prescribed pain relief and anti-inflammatories manage discomfort effectively for most patients. A soft diet — soups, yoghurt, mashed foods — is recommended for the first few days, avoiding very hot, hard or spicy foods. Most patients feel well enough to return to normal activities within three to five days. Full soft tissue healing takes two to four weeks, with bony healing continuing over several months. Stitches, if used, are usually dissolvable and do not need to be removed.

Key Recovery Tips

• Bite gently on the gauze pad provided for 30 to 45 minutes after the procedure to control bleeding
• Apply an ice pack to the outside of the face for 20 minutes on, 20 minutes off in the first 24 hours
• Avoid rinsing vigorously or using a straw for the first 24 hours — this can dislodge the blood clot
• After 24 hours, rinse gently with warm salt water several times daily to keep the socket clean
• Avoid smoking — this significantly increases the risk of dry socket and delayed healing
• Contact the clinic if you develop increasing pain after the first three days, or if bleeding does not settle

Risks and Possible Complications

Wisdom tooth removal is a routine procedure but carries risks that should be explained honestly before treatment. These include post-operative infection, dry socket, prolonged bleeding, bruising and, in lower wisdom tooth removal, a small risk of temporary or permanent altered sensation in the lip, chin or tongue if the inferior alveolar or lingual nerve is affected. The risk of nerve injury is significantly higher for lower wisdom teeth that are close to the nerve canal — a CT scan is important in these cases.

Wisdom Teeth and Orthodontic Treatment

Wisdom teeth are sometimes cited as a cause of crowding in the front teeth, though the evidence for this is not straightforward. Crowding can occur in adults who have never had wisdom teeth, and many people with wisdom teeth do not develop crowding. An orthodontist may recommend wisdom tooth removal before or during aligner or brace treatment if the wisdom teeth are likely to interfere with tooth movement or the final result — this should be discussed as part of the overall orthodontic plan.
