The human set of teeth is all the teeth an individual will have at a given time. A child usually has 20 primary teeth: eight incisors, four canines, and eight molars, called baby teeth or deciduous teeth. They will gradually be replaced, starting at the age of 7, by the permanent teeth of an adult, which are 32 in number. A full adult set of teeth is composed of eight incisors, four canines, eight premolars and twelve molars. All people do not have the same number of teeth. This may be due to the extraction of permanent teeth or the natural absence of teeth, such as the molars sometimes called wisdom teeth that do not externalize in all people.
