Opis

Man is provided with two sets of teeth, which make their appearance at different periods of life. Those of the first set appear in childhood, and are called the deciduous or milk teeth. Those of the second set, which also appear at an early period, may continue until old age, and are named permanent.

The deciduous teeth are twenty in number: four incisors, two canines, and four molars, in each jaw.

The permanent teeth are thirty-two in number: four incisors, two canines, four premolars, and six molars, in each jaw.
