A number of conditions may require oral surgery treatment including wisdom teeth, otherwise known as third molars, are the last set of teeth to develop. Sometimes these teeth emerge from the gum line and the jaw is large enough to allow room for them, but most of the time, this is not the case. More often, one or more of these third molars fails to emerge in proper alignment or fails to fully emerge through the gum line and becomes entrapped or "impacted" between the jawbone and the gum tissue. Impacted wisdom teeth can result in swelling, pain, and infection of the gum tissue surrounding the wisdom teeth. In addition, impacted wisdom teeth can cause permanent damage to nearby teeth, gums, and bone and can sometimes lead to the formation of cysts or tumours that can destroy sections of the jaw. Therefore, dentists recommend people with impacted wisdom teeth have them surgically removed. However it's not just wisdom teeth that sometimes become impacted and need to be removed. Other teeth, such as the cuspids and the bicuspids can become impacted and can cause the same types of problems described with impacted wisdom teeth. With an oral examination and x-rays of the mouth, doctors can evaluate the position of the wisdom teeth and predict if there may be present or future problems. Studies have shown that early evaluation and treatment result in a superior outcome for the patient.
