Start today using Squibb's Dental Cream — for its help in protecting the delicate Danger Line
Tri e, pyorrhea is practicallj' incurable. But there are a number of ways in which you can guard against it. Clean, healthy gums, sound teeth are a protection. For pyorrhea usually begins with an infection of the gum tissue at The Danger Line. And so ... if you safeguard The Danger Line, pyorrhea will have little chance.
Tlie Danger Line is wliere gums meet teeth. The gum margin. It is one of the most important tissues of the moutli. Never cause it to bleed by using too stiff a brush or a gritty dentifrice. Xever wound it with tootlipicks or liurt it with strong astringents. And • . . never allow acids to irritate it.
At the edge of The Danger Line is a tiny crevice too small for your tooth-brush to reach. Fermenting food particles collect here and generate destructive acids which irritate tlie gum tissue. No wonder the delicate gums sometimes become inflamed — and the more they recede, the wider the road is open to infection.
Ordinary dentifrices, ordinarj' methods are ineffectual against such a menace. But there is a safe way to combat these acids. Brush your teeth rcgularh' M-ith Squibb's Dental Cream. It contains 50% Squibb's Milk of Magnesia. Plenty of this safe, effective antacid to penetrate crevices and Assures, jichere the brush fails to reach.
