Oral surgery is a specialist branch of dental medicine comprising surgical procedures performed within the oral cavity such as wisdom tooth extraction, root resection and implant placement. The procedures are completely painless and are performed under local anesthesia.
Wisdom teeth (the third molars) are the last adult teeth to come into the mouth (erupt). Most people have four wisdom teeth at the back of the mouth — two on the top, two on the bottom. They usually do not erupt until the late teens to early twenties, however there is significant variation between the reported age of eruption of wisdom teeth. They’re called „wisdom teeth“ because they’re the last teeth to emerge at an adult age when you’re presumably “wiser”.
In some cases, wisdom teeth become impacted because they don't have enough room to come in (erupt) or develop normally. An impacted wisdom tooth may partially emerge so that some of the crown is visible (partially impacted), or it may never break through the gums (fully impacted). Wisdom tooth may fail to erupt in the oral cavity primarily due to a lack of space. The main reason for non eruption of wisdom teeth is some mechanical obstacle and thus lack of space in the dental arch. In general, a tooth becomes impacted when your mouth doesn’t have enough space for it. The tooth may also grow at an angle toward the next tooth.
Your dentist or oral surgeon can evaluate your teeth and mouth to determine if you have impacted wisdom teeth. The best way to identify an impacted third molar is by a panoramic x-ray. Panoramic dental x-ray captures the entire mouth in a single image, including the teeth (as well as four wisdom teeth at the back of the mouth — two on the top, two on the bottom), upper and lower jaws, surrounding structures and tissues.
