traction follow each other too closely, the enamel is 

 often injured. 



Medicines containing iron or acids often injure 

 teeth, and, for this reason, should be taken through a 

 tube. The fact is, unless the doctor pronounces the 

 liquid harmless to teeth, this is a good precaution in 

 taking any medicine. Another thing builders of good 

 teeth will especially avoid is eating much candy or 

 other sweets, for this practice is likely to dissolve the 

 enamel. The noticeably bad teeth of people who 

 frequently eat candy is the best proof of this state- 

 ment. Smoking or chewing tobacco also discolors the 

 enamel of teeth. This is another excellent reason for 

 not forming either of these habits. 



How much beautiful, healthy teeth are admired! 

 How greatly such edged tools may aid in keeping the 

 body strong and well ! How they add to the fine 

 appearance of those who have been wise enough to 

 preserve them ! No person is so handsome or so 

 homely that good teeth cannot improve or poor 

 teeth lessen his attractiveness. No one is so strong 

 that his health cannot be weakened by diseased teeth, 

 nor so weak that sound teeth may not be a source of 

 strength. Are we wisely building and preserving 

 our permanent teeth? Surely any who are careless 

 of edged tools that do such important work are, 

 indeed, foolish builders.
