ABSTRACT:
A toothbrush comprises a handle with a socket at one end. A brush-carrying insert includes a tongue removably mounted in the socket. A brush protrudes forwardly from the tongue. Adjacent a location where the brush is joined to the tongue, a laterally outwardly projecting sealing lip is formed on the insert, which lip bears elastically against a front rim of the socket. The tongue carries locking ledges of different heights which fit into a groove of the socket. The tongue may include a pressure projection which extends through a hole in the socket rear wall to present an exposed face which can be pushed against to expel the insert. Alternatively, the socket rear wall can be elastically displaceable for expelling the insert.
