The dental treatment instrument includes a toothbrush having common brush head dimensions and a nozzle on the backside of the bristle pad thereof. The tip of the nozzle points backward relative to the bristle pad and is inclined away from the handle end of the toothbrush. The bristle pad is used as a rest pad laid against the cheek wall of the user for steadying the movement of the nozzle. In another aspect of the present invention, the toothbrush has a push-button-operated valve mounted in the handle end of the toothbrush for selectively letting water flow through to the nozzle. The push button is partly enclosed in a shroud. The push button is mounted in the shroud with a sliding fit. The shroud prevents water and toothpaste from seeping below the push-button.
