_Dental Treatment._—Open the chamber and remove the putrescent pulp, being careful not to go beyond the apical foramen. Use a barbed broach, then wash out with peroxide of hydrogen on a thread of absorbent cotton wrapped smoothly about the broach. Do not push the instrument up into the canal very far for fear of sending some putrescent matter beyond the tooth. Then withdraw the broach and apply oil of cloves or carbolic acid, leaving the canal open and clean for the gas to escape. Hot foot-baths and headache remedies will relieve the pain. =Gum-boils= are abscessed teeth, and may be deep-rooted or very superficial. The treatment is the same as given above. Hot applications are very often prescribed, but as an infection will always follow the line of least resistance, it can be readily understood why such a treatment should not be given. The abscess may gather in the cheek, necessitating lancing, which will leave a scar. Cold cloths will allay the infection and simplify the treatment to the gums alone. Teeth are withdrawn, leaving unsightly cavities, which could be avoided by a more deliberate treatment. Treat the abscess of the tooth the same as an abscess in any other part of the body, thereby saving the root of the tooth, if not the entire portion, which can be crowned and give a permanent good tooth. Mastication is the most important part of the digestive system, and mastication cannot be done without good teeth. Therefore, it behooves everyone to preserve his own teeth and to give this benefit to others who may not have had dental treatment. There are dentists who will extract a tooth upon the patient’s request, and it is best to seek the most progressive and modern dental doctors for the preservation of the teeth to prevent the untimely loss of a tooth, which means also many times a preventive against other ailments affecting the digestive tract. A good dentist should be consulted at least once a year, although the teeth may appear sound and in good condition. ERUPTION OF THE DECIDUOUS OR MILK-TEETH. Lower central incisors, 6 to 9 months.
