Answer 2

In the seventeenth century, Europeans often used rags or sponges dipped in sulfur oil or a salt solution to rub their teeth clean. Sometimes these rags were attached to a stick to help reach the back teeth, but the teeth were essentially being mopped, rather than brushed. From this practice evolved the first toothbrush, invented in 1780 by William Addis of Clerkenwall, England.

Addis attached hairs from the tail of a cow to the end of a whittled thighbone from the same animal, which was reportedly the only bone strong enough to survive the bristle-attachment procedure and still maintain its strength when wet. Eventually, boar hairs replaced the hairs from the cow’s tail. To this day, descendants of William Addis still manufacture toothbrushes at a factory in England.
