Abstract
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 KNO.sub.3 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.
Claims23
A sticky dental composition adapted for use with a dental tray for treating sensitive teeth comprising:
- a desensitizing agent for reducing dental pain sensations;
- and
- a tackifying agent selected from the group consisting of carboxypolymethylene, gums, proteins, and mixtures thereof, the dental composition having a stickiness so that the dental composition is capable of adhering and retaining a dental tray over a person's teeth for at least about one hour, wherein the dental tray is designed not to exert mechanical pressure onto the person's teeth and gums.
A sticky dental composition adapted for use with a flexible, thin-walled dental tray for treating sensitive teeth comprising:
- a desensitizing agent for reducing dental pain sensations;
- and
- a tackifying agent comprising carboxypolymethylene included in an amount within the dental composition in order that the dental composition has a stickiness and resistance to dilution by saliva so that the dental composition is capable of adhering and retaining a dental tray over a person's teeth for at least about one hour, wherein the dental tray is designed so as not to exert mechanical pressure onto the person's teeth and gums, the carboxypolymethylene being neutralized in order that the resulting dental composition has a pH in a range from about 4 to about 9.
A sticky dental composition for treating sensitive teeth in combination with a flexible, thin-walled dental tray that is designed not to exert mechanical pressure onto a person's teeth and gums, the dental composition comprising:
- a desensitizing agent for reducing dental pain sensations;
- and
- a matrix into which the desensitizing agent is dispersed, the matrix including a tackifying agent selected from the group consisting of carboxypolymethylene, gum, proteins, and mixtures thereof, a polyol, a base, and optionally water, the dental composition having a stickiness and resistance to dilution by saliva so that the dental composition is capable of adhering and retaining the dental tray over a person's teeth for at least about one hour, the dental composition being neutralized to a pH in a range from about 5 to about 7.
