342 DETAILED SYNTHESIS. 



1009. Inf. HOT OR COLD SUBSTANCES should not be brought in 

 contact with the teeth. Children should be cautioned against eating 

 snow, ice, etc. 



1010. Remark. BITING HARD SUBSTANCES, cracking nuts, biting 

 off thread, untying knots with the teeth, endanger the enamel. 



1011. Remark. In THE SALIVA OF SOME PERSONS' MOUTHS the tar- 

 tar is so abundant that very frequent brushing is necessary to prevent 

 its deposit : the general health of the person should be unproved, as it 

 also should be if the gums are spongy, for by proper attention to diet, 

 etc , both evils can be remedied. 



1012. Remark. IF A TOOTH MANIFESTS DECAY, the decayed part 

 should be thoroughly removed and its place supplied with gold. 



1013. Remark. SOMETIMES, WHEN THE TEETH BECOME VERY TROU- 

 BLESOME, loosened from their sockets, or are so extensively decayed, and 

 the sockets so diseased, that they are extremely painful and almost un- 

 endurable, perchance exciting neuralgia, dyspepsia, &c., it will be advis- 

 able to remove them altogether, and have a set of artificial ones insert- 

 ed, the result of which will be in some cases a most extraordinary im- 

 provement in health and the enjoyment of life.* 



1014. THE USE OF THE TEETH is to masticate the 

 food ; a most important preparation to its after-digestion. 



1015. Illus. It is very difficult to fatten animals that cannot mas- 

 ticate ; and old people, who have lost their teeth, are very much subject 

 to derangement of the digestory canal. 



1016. Remark. When the teeth become so few as to be useless, 

 or when gone entirely, their place should be supplied by artificial ones, 

 that can be made to serve the purpose almost as well as natural ones. 

 Many people would very much promote their comfort and health, and 

 of course prolong their lives, if they would adopt artificial teeth as soon 

 as they cannot masticate well with their natural ones.

* The author believes, from what he has seen, that sets of teeth upon vulcanized 

 rubber, though very much less expensive, are preferable to those upon gold. He 

 has had the occasion, and been interested to notice, several such made by Dr. Fuller, 

 a dentist in his neighborhood, and they serve their purpose most admirably, as it 

 respects appearance, comfort in wearing, and durability; and if he had occasion for 

 artificial teeth, he certainly should have them set in this manner, even if they cost 

 the more.
