ABSTRACT:
An appliance for treating teeth, such as human teeth, by providing them with a reinforcing acid-resistant layer of a tooth decay retarding agent. The appliance includes a vibrator for producing ultrasonic vibrations, this vibrator terminating in an elongated vibratory tip. A casing houses the vibrator and has a tubular open end region in which the tip is at least partly accommodated. This tubular open end region of the casing carries an elastic membrane wall which extends across the tubular open end region of the casing and through which the tip extends so that the tip has a free end situated outwardly beyond this elastic membrane wall. The elastic membrane wall fluid-tightly engages the vibratory tip while surrounding the latter, and the membrane wall maintains this fluid-tight engagement with the tip during vibration thereof. The tubular open end of the casing is adapted to be attached to a tray which has a hollow interior provided with a liquid vibration-transmitting medium, the tip piercing into the interior of the tray to engage the liquid medium therein when the tray is attached to the casing at the tubular open end region thereof.
