Every year, millions of toothbrushes are thrown out all over the western world. Made of plastic, regular tooth brushes end up in landfills, and pollute the environment. Invented by a dentist in Brisbane Australia. The environmental toothbrush uses fast growing, and bio-degradable, bamboo. Even their packaging is bio-degradable! Keep petroleum under the ground and not in your mouth...comes in several hardnesses, and a kids size too!
