Abstract

A method and composition for preventing, or reducing the risk of, dental caries. Pursuant to the present invention, a chewing gum is provided that includes a therapeutically effective amount of calcium glycerophosphate. The chewing gum, by including a therapeutically effective amount of calcium glycerophosphate, not only eliminates any cariogenic effects of the chewing gum itself, but actually improves dental health when chewed before or after a meal containing fermentable carbohydrates.

Claims

1. A chewing gum for reducing the generation of dental caries, the chewing gum not including fluoride and comprising:

a water insoluble base portion;

a water soluble portion;

a flavor agent; and

at least 0.5% by weight calcium glycerophosphate incorporated in the water insoluble base portion and water soluble portion.

2. The chewing gum of claim 1 wherein the chewing gum includes sugar.

3. The chewing gum of claim 1 wherein the chewing gum is wax free.

4. The chewing gum of claim 1 wherein the chewing gum is a low calorie chewing gum.

5. The chewing gum of claim 1 wherein the chewing gum contains other therapeutic agents, other than fluoride, for preventing dental caries.

6. The chewing gum of claim 1 wherein the calcium glycerophosphate includes both α

and β

isomers.

7. A sugar containing chewing gum comprising:

a water insoluble base;

a water soluble portion including sugar; and

a sufficient amount of calcium glycerophosphate, that is incorporated in the water insoluble base and water soluble portion to offset the cariogenic properties of the sugar without the need for other therapeutic agents for preventing dental caries.

8. The chewing gum of claim 7 wherein the chewing gum is wax free.

9. The chewing gum of claim 7 wherein the gum is a low calorie chewing gum.

10. The chewing gum of claim 7 wherein the calcium glycerophosphate comprises approximately 0.5% to about 7.0% by weight of the chewing gum.
