Abstract
Abstract A member for use in the treatment of caries in the teeth with fluoride or other chemicals which are carried by a section of the member which may be detachable. The member is worked between two teeth at a contact area to place the detachable section in contact with the teeth. The chemical agent is applied to the detachable section either before or after it is placed in contact with the teeth. The detachable section remains between the teeth when the rest of the member is removed, and preferably dissolves in the mouth when wet.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
166 words
A dental caries treatment device comprising a thin plastic, fabric, paper or metal foil strip carrier dimensioned in thickness to be sufficiently thin to fit between two teeth at a contact area thereof and slightly separate those teeth from each other, and a thin caries treatment section which ultimately dissolves when wet with saliva, said treatment section including absorbent material affixed with adhEsive to said thin strip carrier and covering an aperture at the bottom edge of the strip, said absorbent material being dissolvable when wet with saliva, said thin strip carrier having a linearly extended leading strip edge for entering the contact area first so that said thin strip carrier can be worked between the teeth at the contact area to place said treatment section at the contact area for detachment to remain between the teeth when said carrier is removed, and said detachable treatment section remaining between the teeth and carrying a caries treatment material for treating the teeth particularly at the contact area.
