What is Wisdom Tooth Removal?
Wisdom teeth are the last molars to appear, usually in the late teens or twenties. When they are impacted or cause problems, removal is often recommended.
Why is it needed?
Wisdom teeth that cannot fully emerge can cause pain, infection, decay in neighbouring teeth, or crowding. Removal prevents these problems.
Symptoms & signs
- Pain or pressure at the back of the jaw
- Swelling or tenderness around a partially erupted tooth
- Difficulty opening the mouth or bad taste (sign of infection)
- Repeated gum infection over the wisdom tooth
Common causes
- Insufficient space for the tooth to erupt (impaction)
- A tooth erupting at an angle
- Difficulty cleaning a partially erupted tooth
The procedure, step by step
- Assessment & X-ray. An X-ray shows the position of the tooth and its roots to plan removal.
- Numbing. Local anaesthetic numbs the area for a comfortable procedure.
- Removal. The tooth is removed; an impacted tooth may need a small incision. Stitches are placed if required.
- Aftercare guidance. You receive detailed instructions for smooth healing.
Number of visits
Usually one visit, with a possible follow-up to review healing or remove stitches.
Recovery time
Swelling and discomfort are common for a few days and usually improve within a week. Full healing of the socket takes a few weeks.
Benefits
- Relieves pain and recurring infection
- Protects neighbouring teeth from damage
- Prevents future crowding or cyst formation
Possible risks
- Swelling, bruising, and discomfort after surgery
- Dry socket if aftercare is not followed
- Temporary jaw stiffness
- Rarely, nearby nerve irritation, your dentist will discuss this based on your X-ray
Alternatives
- Monitoring without removal (for symptom-free, well-positioned wisdom teeth)
- Treating a gum infection first if immediate removal is not needed
Aftercare
- Apply cold compresses to reduce swelling in the first 24 hours
- Eat soft foods and keep the mouth clean with gentle salt-water rinses after the first day
- Avoid smoking and straws to prevent dry socket
- Take prescribed medication as directed and rest
When to visit a dentist
See a dentist if you have pain, swelling, or repeated infection around a wisdom tooth. An X-ray will determine whether removal is advisable.

Frequently asked questions
Do all wisdom teeth need to be removed?
No. Wisdom teeth that are healthy, fully erupted, and cause no problems can often be left in place and monitored. Your dentist will evaluate whether this treatment is suitable for you after a clinical examination and any necessary X-rays.
Is wisdom tooth removal painful?
The procedure is done under anaesthetic and is generally comfortable. Some swelling and soreness afterwards is normal and manageable.
How long is recovery?
Most people feel much better within a week, though full socket healing takes a few weeks. Following aftercare speeds recovery.
