The movable handle portion is in two relatively separable parts having mutually interengageable end portions releasably securing the parts together, one of the parts containing a mouthwash chamber with a supply of mouthwash and the other parts containing a floss chamber with a supply of dental floss. The movable handle is readily releasably secured to the first handle portion.
