1. In a device for providing at the surface of at least one tooth a reinforcing layer of a decay-retarding agent, enclosure means for enclosing an ultrasonic wave transmitting medium, said enclosure means including a sheet material which defines a hollow interior space for receiving the ultrasonic wave transmitting medium, said sheet material having at least a portion which defines at the exterior of the sheet material a recess which is adapted to receive at least one tooth situated closely adjacent to said portion of the sheet material with a decay-retarding agent situated between and contacting the tooth and the sheet material, said sheet material having the property of being impermeable to the ultrasonic wave transmitting medium so that the latter cannot pass through the sheet material while said sheet material also has the property of transmitting ultrasonic waves from the medium in the interior of said enclosure means through the sheet material thereof to a tooth which is contacted by the decay-retarding agent, said enclosure means having a substantially U-shaped configuration provided by a pair of legs joined by a transverse portion of said enclosure means which is adapted to be situated at the front teeth, said enclosure means including an elongated tubular portion projecting outwardly from said transverse portion and terminating in a free end distant from said transverse portion, said tubular portion and U-shaped portion defining a common interior space for receiving the ultrasonic wave transmitting medium, and seal means situated at said free end of said tubular portion for sealing off the hollow space of said enclosure means.
