The wisdom tooth (or third molar) is usually the last tooth to erupt into the mouth any time after about 16 years of age.
Frequently there is not enough room to accommodate wisdom teeth and as such they do not come into the mouth normally.
When this happens, the wisdom teeth are said to be “impacted”. Wisdom teeth are usually either impacted forwards into the front tooth or backwards into the jaw bone.
An impacted wisdom tooth can cause a number of problems, hence the need for removal. Most commonly these are:

What type of anaesthetic is used?
A number of options are available:
Local anaesthetic – This is an injection into the gum surrounding the wisdom tooth. The injection takes a couple of minutes to numb the area and ensures that you won't feel any pain while the wisdom tooth is being removed. This is the best option for wisdom teeth that are simple to remove.
Local anaesthetic and intravenous sedation – In addition to a local anaesthetic injection, you can also receive an injection in your arm to help you feel relaxed and less aware of the procedure. Keep in mind that this option requires an anaesthetist to attend to you.
General anaesthetic – In most cases, wisdom teeth can be removed with a day-care general anaesthesia, which allows patients to return home on the same day of the surgery. This procedure is usually performed at a hospital.
How long does it take to remove a wisdom tooth?
The time required for wisdom tooth extraction can vary depending on the complexity of the procedure. While some teeth may be extracted in a few minutes, more difficult cases that require cutting the tooth into pieces can take up to 30-40 minutes.
Is there anything else I need to do after the surgery?
After surgery, keeping the extraction sites clean is crucial for the first few weeks. If cleaning is difficult due to soreness, it's recommended to rinse gently with mouthwash or warm salt water (1 teaspoon of salt in 1 cup of warm water) starting the day after the surgery to prevent food debris buildup.
Do I need to take time off work?
Usually it will be necessary to take 2 to 5 days off work and avoid strenuous exercise during this time. Depending on the type of anaesthetic used, you may not be able to drive (24 hours after intravenous sedation and for 48 hours after a general anaesthetic).
