They may not come in the above regular order even in well children. The
upper front teeth may come first. If the child is sickly there may be
marked irregularity in the order in which they appear. Twenty teeth
comprise the first set.

THE PERMANENT TEETH.--This set consists of thirty-two teeth. They begin
about the sixth year and they are usually not complete until the
twentieth year. They appear in the following order:

First molars 6 years
Incisors 7 to 8 years
Bicuspids 9 to 10 years
Canines 12 to 14 years
Second molars 12 to 15 years
Third molars 17 to 25 years

castile soap or a powder. The teeth of every child should be examined by
a dentist every six months. All cavities should be filled with a soft
filling. The milk teeth should not decay, but should fall out, or be
forced out by the second set. A child should be taught to gargle early
and a mouth wash should be used morning and night.

have an influence. Children who are sickly and puny
