ABSTRACT:
An interdental toothbrush has a hinged locking retainer on the end of an elongated handle. The locking retainer has a hole which is positioned relative to a groove in the handle so that a twisted wire brush may be locked into place simply by inserting it and closing the retainer. A latch on the locking retainer has a top end with a double cam surface thereon. One of the cam surfaces guides the latch into a locking position as the retainer is closed. The other of the cam surfaces releases the locking retainer when pushed.
