A toothbrush having a replaceable bristle base, comprising, in combination:
- a handle having a long dimension, and having a head portion having a top surface, an upwardly sloping region at an end thereof, and a longitudinal slot in said top surface along the long dimension of the handle;
- and
- a unitary bristle base having an upper surface, a bottom surface, an upwardly sloping region at an end thereof, bristles extending from said upper surface, and a longitudinal protrusion extending from its bottom surface,
- wherein said longitudinal protrusion in said bristle base conforms in contour and size to said longitudinal slot in said handle, said bottom surface of said bristle base conforms in contour and size to the top surface of said head portion of said handle, so that the bristle base can be selectively inserted into, and removed from, the head portion of the handle, and said upwardly sloping region in said head portion conforms in size and contour to said upwardly sloping region of said bristle base such that said bristle base can be inserted into said handle in a sled-like manner.
