The roots of your teeth are the first to form. They then push the visible part of the tooth, known as the bud, through your gums. Wisdom teeth typically have two to three roots, but they can have more. As a result, if your wisdom teeth need to be extracted, it is easier to do so before the roots take hold. When removing teeth, surgeons prefer to leave some of the roots in place. A root provides them with something to grasp because removing a tiny tooth bud can be difficult.
