Removal of third molars that are impacted, infected or causing crowding or pain.
What it involves
Wisdom teeth often emerge late and may be blocked by other teeth or the jaw. They can become impacted, trap food, cause gum infection or damage neighbouring teeth. Removing them can be simple or a surgical procedure.
Who it suits
Dentists recommend removal when wisdom teeth cause repeated infection, decay, damage to the next tooth or cysts. Removing healthy wisdom teeth only to prevent future problems is a decision that depends on the person and local guidance.
How it usually works
An X-ray or 3D scan shows the position of the teeth and nearby nerves. Under local anaesthetic, sometimes with sedation or general anaesthesia, the gum is opened if needed and the tooth removed. Stitches may be used. Recovery typically takes several days to a couple of weeks.
Risks and things to consider
Swelling, pain, bruising and limited mouth opening are expected. Dry socket and infection can occur. Nerve injury, causing temporary or rarely lasting numbness in the lip, chin or tongue, is a known risk, mostly for lower wisdom teeth close to the nerve.
Questions to ask before you decide
How close is the nerve on my scan and what is the risk? What type of anaesthetic is used and who monitors me? How long should I stay in the country before flying home?
