All about Wisdom tooth extraction
Overview
Wisdom tooth extraction is a surgical procedure to remove one or more wisdom teeth — the four permanent adult teeth located at the back corners of your mouth on the top and bottom.
If a wisdom tooth doesn’t have room to grow (impacted wisdom tooth), resulting in pain, infection or other dental problems, you’ll likely need to have it pulled. Wisdom tooth extraction may be done by a dentist or an oral surgeon.
To prevent potential future problems, some dentists and oral surgeons recommend wisdom tooth extraction even if impacted teeth aren’t currently causing problems.
Why it’s done
Wisdom teeth, or third molars, are the last permanent teeth to appear (erupt) in the mouth. These teeth usually appear between the ages of 17 and 25. Some people never develop wisdom teeth. For others, wisdom teeth erupt normally — just as their other molars did — and cause no problems.
Many people develop impacted wisdom teeth — teeth that don’t have enough room to erupt into the mouth or develop normally. Impacted wisdom teeth may erupt only partially or not at all.
An impacted wisdom tooth may:
- Grow at an angle toward the next tooth (second molar)
- Grow at an angle toward the back of the mouth
- Grow at a right angle to the other teeth, as if the wisdom tooth is “lying down” within the jawbone
- Grow straight up or down like other teeth but stay trapped within the jawbone
Problems with impacted wisdom teeth
You’ll likely need your impacted wisdom tooth pulled if it results in problems such as:
- Pain
- Trapping food and debris behind the wisdom tooth
- Infection or gum disease (periodontal disease)
- Tooth decay in a partially erupted wisdom tooth
- Damage to a nearby tooth or surrounding bone
- Development of a fluid-filled sac (cyst) around the wisdom tooth
- Complications with orthodontic treatments to straighten other teeth
