Many people require removal of their third molars also known as wisdom teeth. As with any surgical procedure, there are some possible risks and complications. The decision on third morlar removal should be decided by a patient and their dentist. 

Is it necessary to remove wisdom teeth? 

Wisdom teeth are a valuable asset to the mouth when they are healthy and properly positioned. Often, however, problems develop that require their removal. When the jaw isn't large enough to accommodate wisdom teeth, they can become impacted (unable to come in or misaligned) Wisdom teeth may grow sideways, emerge only part way through the gum or remain trapped beneath the gum and bone. 

Extraction of third molars is generally recommended: 

• When wisdom teeth only partially erupt;

• When there is a chance that poorly aligned wisdom teeth will damage adjacent teeth; 

• When a cyst (fluid-filled sac) forms, destroying surrounding structures such as bone tooth roots.
