Children who had carious lesions in anterior teeth were referred for treatment if they did not have a family dentist.
Pain may be stopped by removing the cause of irritation, as, for example, by the extraction of a carious tooth or by rendering the nerveendings insensitive to irritation, as by the application of cocaine; by preventing its transmission along the spinal cord by antipyrin, phenacetin, acetanilide, cocaine, &c.; or by dulling the perceptive centre in the brain by means of opium or its alkaloids, by anaesthetics, and probably also, to a certain extent, by antipyrin and its congeners.
A pledget of cotton saturated with passiflora and introduced into a carious tooth has promptly allayed violent toothache.
