MOUTH AT 9 YEARS. 



Fig. 253. — Tables of incisors (nat. size). 



Indications of crib-biting are visible in this mouth. A slight 

 groove has begun to show at the neck of the upper corner incisor 

 (Fig. 251). The cavities have disappeared out of the upper cen- 

 tral incisors, and all the incisors have decreased in width.
