In other cases the patient may be directed to poultice the gum with pieces of hot figs, or to apply the more convenient capsicum plasters until the pus is drawn through the alveolus into the gum, whence it is readily evacuated with a lancet. Drilling through gum and alveolus gives speedy relief in many cases, but is too heroic a method for general practice. Whenever the patient resists the manipulation necessary to vent the canals, it becomes a question of the judgment of the operator, whether he will attempt to get rid of the pain by trusting solely to local applications to the gum, or whether he will at once extract the tooth. An excellent procedure in these cases, where the cavity df decay is very accessible, and also in cases of obstinate pulp in- flammation without exposure, is to administer gas and freely open up the pulp-chamber with a large clean bur in the dental engine.
