Abstract
A toothbrush head consists of a hollow body (16) closed at one side by a flexible membrane (13) formed with cavities (17) to hold bases of tufts of bristles. The cavities form protrusions extending up inside the body (16) which are pushed against by a reciprocating finger (18) to tilt and move the bristles relative to the body (16).
