Understanding Supernumerary Wisdom Teeth: What Causes Extra Teeth?

Humans typically have four wisdom teeth, two in the upper jaw and two in the lower jaw. However, some people may develop an additional wisdom tooth, called a supernumerary wisdom tooth. This can occur due to genetic variations or other factors. When a person has six wisdom teeth, it is usually because they have one supernumerary wisdom tooth on each side of the upper and lower jaw.
