Schroder's Dentrifice.
Take powder of Tiles half an ounce; moisten it, at several times, with Oil of Tartar, 'till it hath imbibed its own Weight, and bring it to the consistence of Paste, then add white Tartar 3 drams; Bread burnt black 2 drams; make it into Powder.
Rub the Teeth with it when grown foul, yellow or black, and wach it off with warm Wine.
The Teeth are never overgrown with Lapis Dentalis, while the Gums are found, and rise up to the middle of the Tooth, in a pointing shape, and stick fast to it. But Gums that are spongy,apt to bleed, flaccid and loose from the Teeth, and so give way for external Injuries to come at the Teeth, and don't supply them with good Nourshment but pervert it: Such occasion there stony Concretions.
