Tooth

Human dentition consists of two main types of teeth: primary (deciduous) teeth and permanent (adult) teeth. Primary teeth, also known as baby teeth or milk teeth, begin to erupt around six months of age and are gradually replaced by permanent teeth starting around age six. There are 20 primary teeth in total, comprising four incisors, two canines, and four molars in each dental arch. Permanent teeth, on the other hand, begin to erupt around age six and continue to emerge throughout childhood and adolescence, eventually replacing the primary teeth. The adult dentition consists of 32 permanent teeth, including eight incisors, four canines, eight premolars, and twelve molars in each dental arch.
