It is a fact that in 8 out of 10 cases, back teeth decay first. Why? Because the ordinary tooth brush does not reach and clean the back teeth.
That is the reason for the big end-tuft of the Pro-phy-lac-tic Perma-Grip. It reaches the hard-to-get-at back teeth, removes every tiny food particle—cleans thoroughly, protects against decay—as no other brush can.
Pro-phy-lac-tic Perma-Grip is the only tooth brush with the exclusive Perma-Grip method of sealing the bristles in the handle firmly, securely.
Insist upon genuine Pro-phy-lac-tic Perma-Grip. Look for the hyphenated name.
