Ossification (Calcification) of the Dental Pulp is indicated by pain of a neuralgic character, which commences in an uneasy feeling, and changes to what has been described as a gnawing sensation, similar to that which attends the knitting together of the fractured parts of a bone. It may be continuous, but not constantly severe, and frequently amounts to no more than an uneasy sensation; at other times it may be sharp and darting, affecting the side of the head, and all the branches of the superior maxillary division of the fifth pair of nerves. The affected tooth is free from soreness and discoloration.
Apply anodynes, such as lead water, and those indicated in "acute inflammation of pulp" to relieve the pain. Open the pulp chamber, and completely extirpate the pulp.
