A disposable prophy angle is mounted to an electric tooth polisher that has a controller, a handle having a motor and a driving shaft. The prophy angle is mounted to the handle and has a casing, a driven shaft, a surface-polishing member and a crevice-cleaning member. The casing is mounted to the handle and has a cavity and a distal open end. The driven shaft is mounted rotatably in the casing, rotates in response to the motor and has a mount. The surface-polishing and crevice-cleaning members are detachably mounted on the mount simultaneously. The tooth polisher with both the surface-polishing and crevice-cleaning members can be used to clean teeth without the need to replace the members and is timesaving.
