Dental compositions having a sticky matrix material for treating sensitive teeth

摘要

The present invention discloses sticky dental compositions and methods for treating sensitive teeth. For maximum comfort, an improved dental tray that is thin-walled, flexible and lightweight is used to hold the dental composition adjacent the desired tooth surfaces. The dental compositions include a sticky matrix material into which is dispersed a desensitizing agent such as KNO3 and other optional dental agents. 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 patient's teeth.
