Why do we have wisdom teeth?

According to anthropologists, the last set of molars or wisdom teeth were provisions for our ancestors to help them chew coarse, rough food such as hard items like nuts, roots, meets, and leaves. The larger jaw was common in our ancestors that easily accommodated the wisdom teeth. This allowed them to erupt into the mouth normally. Experts believe that our jawline has become less broad and smaller over the years due to how food is prepared and consumed. Wisdom teeth are no longer necessary, and our jaws no longer have room to accommodate them, which is why wisdom teeth typically need to be extracted.
