PCT No. PCT/NL80/00016 Sec. 371 Date Jan. 9, 1981 Sec. 102(e) Date Jan. 9, 1981 PCT Filed May 9, 1980 PCT Pub. No. WO80/02368 PCT Pub. Date Nov. 13, 1980.A device for treating teeth with a tooth treating medium, such as a fluorine-containing agent, in which two U-shaped trough members are formed of a soft synthetic plastic. One of the trough members is designed to be applied about the upper teeth and the other about the lower teeth. The upper and lower trough members are interconnected at their bottom by a single centrally located connector element. A forwardly projecting handle on the connector element enables the device to be hygenically handled. The two U-shaped members are centered relative to each other by two sets of intermeshing ridges thereon.

I claim:
1. A device for treating teeth with a tooth treating medium, such as a fluorine-containing agent, comprising two substantially U-shaped trough members made of soft synthetic plastics material, one of said trough members being designed to be applied about the upper teeth and the other about the lower teeth, said members being interconnected by at least one flexible connector, characterized in that the two U-shaped members are interconnected by a single centrally located projecting connector element, provided centrally in the plane of symmetry of each of the two members and connecting with said members at the trough bottoms with the centrally located single connector element projecting forwardly from the mouth when said two trough members are positioned to be placed on the teeth to provide a forwardly projecting handle to enable the device to be hygenically handled by the operator without entering the cavity of the mouth, said connector element being provided with means for centering the two U-shaped members relatively to each other, including two sets of centering ridges extending in a direction parallel to said plane of symmetry with the two sets of ridges intermeshing when said two trough members are positioned to be placed on the teeth, each of said ridges being bevelled in the direction of the adjacent U-shaped members.
