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.
Most babies start teething when they are between 6 and 8 months old. The lower-central incisors â the two bottom front teeth â are the first to come in, followed by the upper-central incisors (two top front teeth).
