This processstarts early in intra-uterine life and should be completedat the end of infancy. At birth, although nothing butsmooth gums are to be seen, the alveolar processes enclosethe twenty temporary or milk teeth in embryo. Whenbeginning to come through the gums, they usually ap-pear in groups. The first to be cut are apt to be one or.

The rest are gradually evolved, usually in thefollowing order: upper central incisors, upper lateral inci-sors, four anterior molars, four canines, and finally thefour posterior molars. The first dentition should becompleted by the end of infancy at the age of two and ahalf years. There is always some variation, within the limits ofhealth, as to the exact time of the evolution of the may be said, however, that much delay in teething isan evidence of faulty nutrition or constitutional disease,such as rickets.
