200 THE TEETH 



alveolar membrane results in a bony enlargement on the side of 

 the face if the superior molar is involved. A swelling of the 

 jaw and fistula may result if a lower molar is involved (Fig. 5Y). 

 The treatment consists in the prompt removal of the tooth. 

 This is more difficult in young animals than it is in the middle- 

 aged or old. Unless the tooth is already loosened it may be 

 necessary to remove it by trephining.
