When is it necessary to remove wisdom teeth?
Wisdom teeth are a important asset to the mouth only when they are healthy and properly positioned. However, problems often occur that require their removal. When the jaw isn't large enough to accommodate wisdom teeth, they can become impacted. The Wisdom teeth may then grow sideways, may remain trapped beneath the gum and bone or emerge only part way through the gums.
Extraction of wisdom teeth is normally recommended when:

• Wisdom teeth only partially erupt. This leaves an opening for bacteria to enter around the tooth and cause an infection.
• There is a chance that poorly aligned wisdom teeth will damage adjacent teeth by putting pressure on the other teeth.
• A cyst forms, damaging surrounding structures such as bone or tooth roots.

Ask your dentist about the health and positioning of your wisdom teeth.
