The wonders of toothbrushes

Just a little note we were watching the history channel on the beginning of toothbrushes. The bristles used to be made out of the boar's hair. In the 1800 they used to use ammonia on the brush to make your teeth white. Problem is ammonia rots your teeth. Another little fun note, America gave their prisoners of wars in Germany hollow toothbrushes with maps of Germany inside for their escape from the prison camp. Isn't that neat?
