Teeth are named by their set, arch, class, type, and side. Teeth can belong to one of two sets of teeth: primary (baby) teeth or permanent teeth. Often, deciduous may be used in place of primary, and adult may be used for permanent.
Second Molars -- Likewise, these are called 12-year molars. You get the picture! Both first and second molars come in the form of primary and secondary teeth. Once your baby teeth fall out, they will be replaced with permanent first and second molars. Third Molars -- The third molars, or wisdom teeth, are the final molars to come in. You'll probably start to see wisdom teeth erupt between the ages of 17-21. They're called wisdom teeth because by the time they erupt, we're supposed to be old enough to have wisdom.
