Toothbrush

Thetoothbrush is an oral hygiene instrument used to clean the teeth, gums, and tongue. It consists of a head of tightly clustered bristle, atop of which toothpaste can be applied, mounted on a handle which facilitates the cleaning of hard-to-reach areas of the mouth.

Over 1 billion toothbrushes are disposed of into landfills annually in the United States alone. $
