If you're a teen who's 13 or older, you probably have most of your permanent, or adult teeth. The last of the permanent teeth to appear are called third molars or wisdom teeth. They usually begin to erupt, pushing their way through the gums, between ages 17 and 21.
Wisdom teeth that are healthy and properly positioned can be an asset. For some teens, however, one or more of the four wisdom teeth may be missing, having never formed. In most cases, wisdom teeth remain impacted, trapped beneath the gum and bone against the teeth in front of them. They may partially erupt because the jaw can be crowded by other permanent teeth. The partially erupted teeth may tilt sideways and may cause damage to adjacent teeth.
Regular dental checkups are important not just for having your teeth cleaned but for allowing your dentist to track the progress and condition of your adult teeth. After examining your mouth and taking X-rays, your dentist can evaluate your wisdom teeth and discuss whether or not they should be removed.
