 PREFACE. 
 
 Knowing that the crowning and bridging of 
 teeth is but imperfectly understood by the public, 
 and feeling that it is the duty of Dental Surgeons to 
 keep their patients posted in all that is new, I have 
 prepared this illustrated pamphlet to show what can 
 be accomplished in this department.

 CROWN AND BRIDGE WORK. 
 
 Great progress has been made in conservative dentistry in tiie last ten j'ears, 
 and in no department has greater advancement been made than in the crowning 
 and bridging of teeth. 
 
 A dentist who understands this important branch of Prostiietic Dentistry is 
 enabled to save teeth and roots that a few years ago were extracted by thousands ; 
 he is also able by adjusting teeth to natural roots to save patients the annoyance 
 and discomfort of wearing a plate, to, say notlung of the irritation to which the 
 sensative tissues of the palate are subjected by the contact of nonconducting 
 material like vulcanite. The successful practice of crown and bridge work 
 demands the greatest skill, finest manipulation and best judgment; it also 
 requires some originality in methods of construction and application, for many 
 of the cases presented for treat- 
 ment are most complicated. The 
 adjustment of crowns or bridges 
 to diseased roots cannot be too 
 severely condemned, as also the 
 construction of crowns or bridges 
 without di'e consideration of the 
 force and direction of mastication. 
 Many persons have an idea that 
 the removal of a pulp (nerve) in 
 the preparation of a tooth for a 
 crown or bridge is attendee! with 
 great pain. This is erroneous, for 
 a pulp (nerve) can now be 
 removed withoiit any pain by the 
 use of cocaine or ether spray. It 
 may also be added that a pulpless 
 (without nerve) tooth or root will 
 remain as firmly attached to the 
 alveolar wall as it would if the 
 pulp (ner/e) were intact, and 
 a properly constructed crown or 
 bridge, carefully adjusted, will 
 give as good service as the natural 
 teeth. 
 
 Fig. 1 shows a vertical section 
 of a lower incisor and jawbone 
 (15 diameters); 1, enamel; 2, 
 dentine; C, is phiced in space 
 occupied by nerve (pulp) ; that is 
 the canal that receives the pin of 
 an artificial crown ; 3, cementum ; 
 4, ic^eriosteum which supplies the 
 root with nutrition and serves as 
 a cushion to relieve force of mas- 
 tication ; 5, bone of lower jaw.
