the mouth must be packed full of cotton, waste, oakum or 

 any other packing material that can be promptly furnished. 

 When there is delay in procuring a suitable packing the 

 finger must be kept over the wound to temporarily arrest the 

 flow of blood. After the mouth is packed full the jaws are 

 closed tightly by encircling them with a dozen wraps of cord 

 and the patient is backed into a stall and kept on the pillar 

 reins for five to six hours, when the packing may be safely 

 removed. 



3. Hemorrhage from the dental artery may occasionally 

 be very profuse, but it is never serious. It is arrested by 

 packing the cavity with wadding of cotton or oakum.

 Decayed Tooth Due to Primary Alveolar Periostitis (Ostertag). 



After-care: — The tooth cavity must be wadded with 

 fresh packing every day for a week, at which time a careful 

 examination of the cavity must be made to remove sequestra 

 or fractured segments of bones, which may delay prompt 

 healing of the wound. In two years the opposing tooth will 

 have elongated into the vacant space and will require trim- 

 ming to the level of its arcade.
