News About Teeth.
“You’ve always been taught, haven’t you, that any acid is bad for your teeth—either natural or stored, but especially natural? But Dr. William J. Gies of Columbia university after four years of study and experiment, declares we’ve been wrong for all these years and years in regard to the care of our teeth and advises us to use as cleansers vinegar, lemon or orange juice or “some food acids." Far from destroying the teeth, he says these acids will preserve them. He says: "Food acids, even in strong solution, have very little effect on the enamel, even during long periods of exposure.” But in ÜBlng food acids as dentifrices don’t make the solution too weak or too strong. Get it right, and if you don’t know what is right, find out somehow —the doctor neglects to tell us.
