What it is
Wisdom teeth are the last molars to erupt, usually in the late teens or twenties. When there is not enough room, they can become impacted. Removal is considered when they cause recurring problems, not simply because they are present.
Who it may suit
- Repeated infection around a partly erupted wisdom tooth
- Decay in the wisdom tooth or the tooth in front that cannot be treated
- Cysts or other changes seen on an X-ray
- Persistent pain or difficulty opening the jaw linked to the area
Signs you may need it
- Swollen, sore gum at the very back of the jaw
- Bad taste or discharge from the area
- Pain when biting at the back
- Difficulty cleaning the last tooth
How the treatment works
- 1
Imaging and assessment
An X-ray, and sometimes a 3D scan, shows the tooth position and its relationship to nearby nerves.
- 2
Planning
Risks, alternatives and whether referral is appropriate are discussed.
- 3
Procedure
Removal under local anaesthetic; the tooth may be sectioned to remove it more conservatively.
- 4
Closure
Stitches are often placed and aftercare is explained.
Visits and recovery
Usually one appointment plus a review. Swelling and limited mouth opening for several days are common and generally improve over the first week.
Benefits
- Resolves recurring infection or pain from the area
- Can protect the second molar from further damage
Limitations
- Not every wisdom tooth needs removing
- Some cases are better managed by an oral surgeon
Risks to be aware of
Every dental procedure carries some risk. Your dentist will discuss these with you in person, based on your own examination and X-rays.
- Swelling, bruising and jaw stiffness
- Dry socket
- Temporary or, rarely, longer-lasting altered sensation in the lip or tongue for lower wisdom teeth
Aftercare
- Use cold packs as advised on the first day
- Eat soft food and keep hydrated
- Follow the rinsing instructions from the day after
- Take prescribed medication as directed
When to contact the clinic
- Worsening pain after the third day
- Fever, spreading swelling or difficulty swallowing
