Abstract
A toothbrush head in which the fixed ends of the bristles are embedded in a mass of a polyurethane gel material incorporated in the head. Typical nylon materials as used for toothbrush bristles are found to bind with polyurethane gels so that advantageously holders for the bristles need not be used. A moulding process is also provided for making the toothbrush head.
