Abstract
This invention relates to a toothbrush, the head of which preferably has a circular or elliptical cross section and carries at least one tuft of bristles, the width of which substantially corresponds to the depth of the sulcular sulcus. The head of the brush is preferably joined to a handle which has a polygonal cross section, preferably a square cross section, the median longitudinal plane of the tuft of bristles advantageously forming an angle of less than 90.degree., preferably an angle of 45.degree., with the plane of at least one surface of the handle having a polygonal cross section, which surface is turned towards the free end of the tuft of bristles.
Claims6
A toothbrush, comprising:
- (a) a handle (1) having a constant polygonal cross-section;
