Abstract
Abstract A soft, chewable lozenge delivering to the mouth a solid unit package comprising a fluoride ion source, a starch adhesive, a polishing agent, a non-cariogenic sweetener in a minimum amount of water for solution such as xylitol or a non-cariogenic sweetener without water such as lycasin, a flavoring agent, if desired, and a combined viscosity builder/softening agent such as vegetable oil, all of which interact with saliva on chewing to coat the surfaces of the teeth, particularly interproximal surfaces, with a sticky mass removable only by brushing with a toothbrush. Chewing of this lozenge aids in incorporating the sticky mass in lingual interdental areas frequently not touched by brushing, especially when one is in a hurry, thereby assuring extra care in brushing to remove. Thus, brushing habits are improved for both adults and children. The unit package of saliva saturated paste thus applied by the lozenge insures adequate dosing for cleaning.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
A soft, chewable lozenge delivering to the mouth a composition forming a sticky coating on the teeth when combined with saliva and completely removable from the teeth only by brushing, said composition comprising: a water-containing, non-cariogenic sweetener in an amount of about 20% to 36% by weight selected from the group consisting of xylitol, lycasin, mixtures of xylitol and sorbitol and mixtures of lycasin and sorbitol serving as the sole sweetening agent; a cleaner-polisher for the teeth in an amount of from about 30% to 60% by weight, which is greater than the amount of said sweetener; a starch adhesive in an amount of about 5% to 10% by weight; and a viscosity builder and softening agent comprising an unsaturated vegetable oil which physically softens the mixture of cleaner-polisher and sweetener while interacting physically with the starch adhesive to thicken the composition and enhance adhesion to the teeth.
Claim 2
Dependent Claim
148 words
A soft, chewable lozenge delivering to the mouth a composition forming a sticky coating on the teeth when combined with saliva and completely removable from the teeth only by brushing, said composition comprising: a water-containing, non-cariogenic sweetener in an amount of about 20% to 36% by weight selected from the group consisting of xylitol, lycasin, mixtures of xylitol and sorbitol and mixtures of lycasin and sorbitol serving as the sole sweetening agent; a cleaner-polisher for the teeth in an amount of from about 30% to 60% by weight, which is greater than the amount of said sweetener; a starch adhesive in an amount of about 5% to 10% by weight; and a viscosity builder and softening agent comprising an unsaturated vegetable oil which physically softens the mixture of cleaner-polisher and sweetener while interacting physically with the starch adhesive to thicken the composition and enhance adhesion to the teeth.
Claim 3
Dependent Claim
23 words
A lozenge as claimed in claim 1 containing a fluoride ion source in an amount of about 0.2% by weight of said composition.
Claim 4
Dependent Claim

Claim 6
Dependent Claim
11 words
A lozenge as claimed in claim 4 including a dispersing agent.
Claim 7
Dependent Claim
16 words
A lozenge as claimed in claim 5 wherein said dispersing agent is a non-ionic dispersing agent.

Dependent Claim
13 words
A lozenge as claimed in claim 5 wherein said dispersing agent includes lecithin.
Claim 9
Dependent Claim
26 words
A lozenge as claimed in claim 1 including an antioxidant in an amount effective to protect said unsaturated vegetable oil from oxidation during mixing and storage.
Claim 10
Dependent Claim
143 words
A composition forming a sticky coating on the teeth when combined with saliva in the mouth and completely removable from the teeth only by brushing, said composition comprising: a water-containing, non-cariogenic sweetener in an amount of about 20% to 36% by weight selected from the group consisting of xylitol, lycasin, mixtures of xylitol and sorbitol and mixtures of lycasin and sorbitol serving as the sole sweetening agent; a cleaner-polisher for the teeth in an amount of from about 30% to 60% by weight, which is greater than the amount of said sweetener; a starch adhesive in an amount of about 5% to 10% by weight; and a viscosity builder and softening agent comprising an unsaturated vegetable oil which physically softens the mixture of cleaner-polisher and sweetener while interacting physically with the starch adhesive to thicken the composition and enhance adhesion to the teeth.
