#1134: Chewbrush

People often chew the ends of their writing instruments.

Today’s invention is a disposable cylindrical sleeve which fits on the end of a pen or pencil.

Bristles, like those on a toothbrush, extend radially outwards from the sleeve so that chewers can clean their teeth and massage their gums -rather than grinding plastic or wood splinters into their mouths.

After use, the sleeve can be discarded and replaced. Sleeves might be flavoured and/or pretreated with mouthwash.
