(Q) What causes the gray film on teeth?
(A) The chemical balance in the system and the throw-off or discharge from breath in the lungs. This is a source from which drosses are relieved from the system, and thus passing through the teeth produce same on the teeth. Keeping such cleansed with an equal combination of soda and salt at least three to four times a week will cleanse these of this disturbance. The use of Ipsab as a wash for mouth and gums will further aid in keeping these conditions cleansed; and any good dentifrice once or twice a day.
