Wisdom teeth are a type of molar that is found in the very back of your mouth and are the last molars to develop. There are four wisdom teeth: upper left, upper right, lower left, and lower right. These teeth usually appear in late teens or early twenties but may become impacted (fail to erupt) due to lack of room in the jaw or angle of entry. The removal of wisdom teeth has become so commonplace that it is almost a rite of passage for young adults.
Dr. Boyd Whitlock will tell you that when a tooth is impacted, it may need to be removed. If it is not removed, you may develop gum tenderness, swelling, or even severe pain. Impacted wisdom teeth that are partially or fully erupted tend to be quite difficult to clean and are susceptible to tooth decay, recurring infections, and yes, even gum disease.
