This disgusting condition is due to a variety of causes, chief among them being a disordered stomach, the result of worms or indigestion, and a diseased condition of the teeth, which is more or less dependent upon the condition of the stomach. Diseases of the lungs, as well as a catarrhal condition of the nasal passages, also affect the breath. Remove the cause; that is, if the stomach is out of order treat for worms and use a good condition pill until the digestive processes are normal. If the teeth are covered with tartar remove it by scaling with a small scraper, such as dentists use, and then clean with an ordinary tooth brush and dental powder. If the breath remains bad after the teeth have been cleaned and the stomach toned up, give twice a day for a week two to ten grains of salol. If there is a catarrhal discharge from the nostrils add a teaspoon-ful of salt to a ten-ounce bottle of water and syringe out the nostrils twice a day with the solution.
