If the pain is bearable and there are no chills and fever, the patient may save the tooth by remaining in bed with a hot-water bottle continually on the face, and taking ten drops of laudanum to relieve the pain at intervals of several hours. Then many hours of suffering may be prevented if the gum is lanced with a sharp knife (previously boiled for five minutes) as soon as the gum becomes swollen, to allow of the escape of pus. The dentist is, of course, the proper person to consult in all cases of toothache, and the means herein suggested are to be followed only when it is impossible to obtain his services. =MOUTH-BREATHING= (_including Adenoids, Chronic Tonsilitis, Deviation of the Nasal Septum, Enlarged Turbinates, and Polypi_).--Any obstruction in the nose causes mouth-breathing and gives rise to one or more of a long train of unfortunate results. Among the disorders producing mouth-breathing, enlargement of the glandular tissue in the back of the nose and in the throat of children is most important. Glandular growths in the upper part of the throat opposite the back of the nasal cavities are known as "adenoids"; they often completely block the air passage at this point, so that breathing through the nose becomes difficult. Associated with this condition we usually see enlargement of the tonsils, two projecting bodies, one on either side of the entrance to the throat at the back of the mouth. In healthy adult throats the tonsils should be hardly visible; in children they are active glands and easily visible. We are unable to see adenoids because of their position, but can be reasonably sure of their presence in children where we find symptoms resulting from mouth-breathing as described below. The surgeon assures himself positively of the existence of adenoids by inserting a finger into the mouth of the patient and hooking it up back of the roof of the mouth, when they may be felt as a soft mass filling the back of the nose passages. Other less common causes of mouth-breathing, seen in adults as well as children, are deviation of the nasal septum, swelling of the mucous membrane covering certain bones in the nose (turbinates), and polypi.
