AbstractThe tooth brush having an anatomically compatible structure has a handle which is twisted in comparison to that of the conventional tooth brush so that a plane passing through the head of the tooth brush bearing the bristles and another plane passing through the handle cross each other at a certain angle. The handle is however preferably divided into two parts, a concavo-convex oblong section contiguous to the neck inclined with respect to the plane of the head and a rhombus-like cross sectioned end part which is also inclined with respect to the plane of the head, but in the opposite direction to that of the oblong section. The handle can be provided with a depression and shaped to fit the thumb and forefinger when gripped by the hand. Because of the structure of tooth brush, the bristles can be applied upright on the teeth, when the hand holds the handle in a more comfortable unstrained position than the conventional tooth brush.
