Wisdom tooth removal

About wisdom tooth removal

Wisdom tooth removal is usually only recommended when a wisdom tooth is causing problems - for example repeated infections of the gum around it (pericoronitis), decay, gum disease, a cyst, an abscess, or food trapping that damages the tooth in front. Healthy wisdom teeth that are fully through and easy to clean are usually left alone.

Many wisdom teeth can be removed by a general dentist under local anaesthetic. If the tooth is difficult to remove, or its roots are close to a nerve, you may be referred to a specialist at a hospital, clinic or another practice. Sedation or a general anaesthetic may be offered for difficult extractions or if you are very anxious.

The NHS says the procedure often takes just a few minutes and should take no more than 40 minutes. Pain and swelling are normal for up to two weeks, usually improving after a day or two.

How it works

1. X-rays are taken to check the position of the tooth
2. The area is numbed with local anaesthetic (sedation or general anaesthetic are sometimes used)
3. The gum is cut if it covers the tooth, and the socket is widened
4. The tooth is removed whole or in 2 or 3 pieces
5. Dissolvable stitches are placed if needed

Pros and cons

Aftercare

• Take paracetamol or ibuprofen for pain
• Eat soft or liquid food until chewing is comfortable
• Keep the area clean by rinsing gently with mouthwash or warm salt water, as advised
• Brush your other teeth carefully, avoiding the wound
• If it bleeds, press on the area for at least 10 minutes with a clean cloth
• Do not smoke, drink alcohol or very hot drinks, or eat hard, crunchy or seedy food
• Do not drive for 48 hours after a general anaesthetic or 24 hours after a sedative injection

Risks and side effects

• Dry socket - the clot does not form properly or is dislodged
• Infection needing antibiotics
• Damage to nearby nerves causing numbness or tingling of the tongue, lip or chin - usually temporary but can last weeks or months
• Ask for an urgent dentist appointment or contact NHS 111 if bleeding will not stop, pain and swelling are severe or worsening, or you have a bad taste with a high temperature or feel unwell

Your dentist should explain the risks that apply to you before you agree to treatment.
