The teeth of a six-year-old child are temporary teeth with the 

 exception of the six-year molar. This is the first permanent 

 Its position is just back of the 





teeth. In order to insure good health, teeth should be straightened 

 and adjusted. Dentists are usually able to obtain better results 

 in correcting these malformations if the teeth are not fully grown. 

 Care of the teeth. When the teeth are not cleaned frequently, 

 a substance known as tartar often forms upon them, usually near 

 the gums, and pre- 'ijfch,

 teeth free from this

 which later becomes 

 hard. The teeth 

 should be brushed 

 at least twice a day 

 with a tooth paste 

 or powder which 

 contains some sub- 

 stance, such as 

 chalk, which is hard 

 enough to rub off 

 all deposits but not 

 hard enough to in- 

 jure the enamel of 

 the teeth. The 

 teeth should be brushed with a fairly stiff brush after each meal, 

 in order to remove all particles of foods, and to stimulate the 

 circulation of blood in the gums. The mouth cavity should then 

 be thoroughly rinsed out with a mouth wash or a solution made
