Abstract
The toothbrush consists of a brush head with bunches of bristles ( ) arranged in a longitudinal bristle bed ( ) and a handle ( ), which is connected to the bristle bed ( ) by a connecting part ( ). The length of the bunches of bristles ( ) varies in the longitudinal direction of the bristle bed ( ) in a wave shape. The first bunches of bristles ( ) are situated at the two outer sides of the bristle bed ( ), have split bristle ends and are of essentially the same length. The second bunches of bristles ( ), whose length varies in the longitudinal direction of the bristle bed ( ), are situated between the two outer sides of the bristle bed ( ). The inventive toothbrush has an improved cleaning action, especially for interdental spaces but also for the gingival line.
