Abstract

A toothbrush (98) includes a handle (100), a head (102) extending from the handle and a tuft (104) of bristles which are joined together at a base end of the bristles and secured to the head at the base end. The tuft has a width and a length. A ratio of the width to the length is about 0.25 or less.
