Technically called “third molars.” wisdom teeth generally appear between ages 17-21. Do they have to be removed? Usually. The difficulty with keeping them–even if they come in straight and you have room for them–is keeping them clean. Also, if they come in crowding your other teeth, they can damage them. It’s important to get them checked to evaluate whether or not they need to be taken out.
