Wisdom teeth, or third molars, are the last teeth to erupt in your mouth and are the teeth least needed for good oral health. Most people have four wisdom teeth that usually erupt through the gums in their late teens or early twenties. Sometimes wisdom teeth remain trapped in the jawbone under the gums because there is insufficient room for them to erupt.
Wisdom teeth can cause gum disease, crowding or other damage to adjacent teeth, decay, and bone destroying cysts. Pain and swelling are the most common symptoms of an issue with wisdom teeth. A special x-ray or radiograph called a panoramic view is usually taken to determine the location of wisdom teeth.
