ABSTRACT:
A tooth brush including a handle and a replaceable bristle insert mounted in a recess formed at the front of the handle. The insert includes front and rear walls interconnected by side walls which taper toward the front wall. The recess of the handle is correspondingly shaped. Locking strips project from the front wall and both side walls of the insert for being snapped into corresponding locking grooves formed in the recess of the handle. Sections of each side wall of the insert and recess are smooth and free of locking strips and locking grooves to create a wedging or clamping action between the handle and insert.
