Wisdom Tooth Extraction

What is an impacted wisdom tooth?

If there isn't enough space for the third molar to grow at the back of the mouth, it becomes impacted and can cause pain, swelling and infection.

Who needs it?

Antibiotics can help treat an infection, but symptoms may flare up again. Extraction may be recommended for impacted wisdom teeth that keep causing problems.

How does the process work?

Your dentist will discuss with you what will happen before, during and after the procedure. The operation is usually done under local anaesthesia, which blocks pain from the gums; you stay awake. The method depends on how deeply the tooth is impacted. Many wisdom teeth can be removed like any other molar.

After the extraction

1. Rest until the local anaesthetic wears off. You will receive advice on caring for your teeth and gums, and painkillers, antibiotics and mouthwash as needed.
2. Do not chew on the area or have hot food or drinks.
3. If your gum bleeds, bite on a folded clean handkerchief or gauze for at least 10-15 minutes. Don't rinse your mouth or lie down until the bleeding has stopped.
4. Don't rinse vigorously for the first 24 hours; after meals, rinse gently with warm salt water.
5. Brush as usual but keep the toothbrush away from the wound for the first couple of days.
6. Start with soft foods and return to your usual diet as your jaw feels less stiff.
7. Dissolvable stitches disappear on their own in 7-10 days; other stitches are removed after a week.

Possible risks

Facial swelling, bruising, pain or jaw stiffness can last up to two weeks; they are usually worst in the first two or three days. As with any operation, complications can include an unexpected reaction to the anaesthetic or excessive bleeding. Specific complications are uncommon but may include infection, accidental damage to other teeth or the jaw, dry socket (the blood clot breaks away and delays healing), numbness of the lower lip or tongue or changes in taste caused by nerve damage, and jaw stiffness.
