A dental mirror includes a mirror assembly and a handle having an interior cavity. The handle further includes a non-circular aperture proximate one end, which communicates with the interior cavity. A push-arm extends through the aperture toward the mirror assembly and has a non-circular shape. The push-arm also has a wiper support, and a sponge is secured within the wiper support. The push-arm is selectively movable to carry the sponge over the mirror assembly, and the aperture prevents relative rotation of the push-arm.
