This consists in the formation of an abscess at the root of a tooth. It is generally the result of decomposition of a dead nerve or of the pulp of a tooth. The first symptoms felt are soreness of the affected tooth, which feels longer than natural. After a few hours, severe pain begins, which continues four or five days, after which, a swelling upon the gum near the tooth may be discovered, which in time, if left to itself, breaks and discharges. If not properly treated, the abscess may continue to gather and break for a long time Proper treatment consists in cold applications to the side of the face, holding ice, or iced-water in the mouth in order to limit the inflammation as much as possible, and lancing of the abscess when it is formed. A skillful dentist should be employed to treat the teeth.
