Also know as adult teeth. These are the teeth that erupt after the primary or deciduous teeth. They are also called the adult teeth. They begin with the eruption of the first or 6 year molar around the sixth year of life. This tooth is immediately distal to the primary second molars (Baby teeth “A,J,K,T”) and does not replace a baby tooth but erupts distal to them. There are 32 permanent teeth in the adult mouth. From the midline moving distally the adult has a central incisor, a lateral incisor, a canine, a first and second pre-molar and then first, second, and third molars in each quadrant. They are identified by numbers beginning with the upper right third molar called tooth number one (this is the upper right wisdom tooth). The numbering system continues mesially to the mid-line before continuing distally to the upper left ending at tooth number 16 in the upper left. This is tooth number 16, the numbering system then drops down to the lower left third molar, this is tooth number 17. The system then moves mesially to the lower midline before continuing to the lower right distal ending with tooth number 32 which is the lower right third molar or wisdom tooth.
