Abstract
Sticky dental compositions which include a sticky, glue-like matrix material for treating a variety of tooth or gum ailments, and methods for treating teeth using such compositions. For maximum comfort, an improved dental tray that is thin-walled, flexible and lightweight is used to hold the sticky dental composition adjacent the desired tooth surfaces. The sticky dental compositions include a sticky matrix material into which is dispersed an appropriate dental agent, such as a bleaching agent, a desensitizing agent, and an anticariogenic agent, an antimicrobial agent. The matrix material preferably includes carboxypolymethylene that has been partially neutralized with a base to reduce etching of the enamel. The carboxypolymethylene adds a unique stickiness to the dental composition which helps to adhere and retain the soft tray material against the person's teeth.
