The toothbrush according to the invention is designed to be elastic and reversibly deflectable in the area of ​​the finger groove (Fm). If the maximum permissible cleaning force on the teeth and gums is exceeded, small but perceptible movements occur between the individual transverse ribs (Qs) in the area of ​​the finger groove (Fm). These movements are easily felt by the user's fingers resting on them, thus allowing the cleaning force to be constantly monitored, controlled, and limited. Furthermore, due to the coordinated design of the transverse ribs (Qs) (essentially in the form of an irregular truncated pyramid) and the essentially trough-shaped transverse recesses (Qa), there is no risk of pinching or chafing of the skin of the fingers, even when the recommended cleaning force is significantly exceeded.and wherein the surface and volumetric contact between all features in the area of ​​the finger groove (Fm) and the fingers resting thereon is consistently / permanently good, comfortable, stable, non-slip and secure, regardless of which specific tooth area in which specific quadrant of the dentition is being brushed or cleaned. The toothbrush according to the invention, in particular a mechanical manual toothbrush, can be manufactured to a high standard and routinely using both single-component and multi-component technologies (with the exception of bristles).
