Common Complications When Extracting Wisdom Teeth
When a person is between the ages of sixteen and twenty, her wisdom teeth emerge (a process called eruption). These are the last teeth to do so. By the time they erupt, however, there is often too little room in the mouth. This results in a problem known as impaction. The molar becomes positioned under the gum tissue in a way that prevents it from emerging properly. This causes swelling and pain for the patient, and can lead to crowding issues once the tooth erupts.
