Sticky dental compositions for adhering a passive-type dental tray over a person's teeth

A sticky dental composition for treating a person's teeth gums, or a combination thereof and adapted for use with a flexible, thin-walled dental tray that is designed so as to not exert mechanical pressure on a person's teeth and gums, said dental composition comprising:

• at least one dental agent for providing a desired treatment of a person's teeth gums, or a combination thereof, wherein the dental agent is selected from the group consisting of dental bleaching agents, anticariogenic agents, antimicrobial agents, and mixtures thereof;
• and
• carboxypolymethylene, including any reaction products of carboxypolymethylene, included in an amount so that the dental composition is capable of adhering and retaining, for a length of time in order to carry out the desired treatment, a flexible, a thin-walled dental tray that is designed so as to not exert mechanical pressure onto the person's teeth and gums, the carboxypolymethylene being treated with a base so that the resulting dental composition has a pH in a range from about 5 to about 7.

A sticky dental composition for providing enhanced treatment of a person's teeth, gums, or a combination thereof in combination with a flexible, thin-walled dental tray that is designed so as to not exert mechanical pressure onto a person's teeth and gums, the sticky dental composition comprising:

• at least one dental agent selected from the group consisting of dental bleaching agents, anticariogenic agents, antimicrobial agents, and mixtures thereof;
• and
• a sticky matrix material into which the dental agent is dispersed, the matrix material including carboxypolymethylene and any reaction products of carboxypolymethylene, a polyol, a base, and optionally water in an amount in order that the resulting matrix material imparts to the dental composition a stickiness and resistance to dilution by saliva so that the dental composition is capable of adhering and retaining, for a period of time in order to carry out a desired treatment, a flexible, thin-walled dental tray that is designed so as to not exert mechanical pressure onto the person's teeth and gms, the base being included in an amount so that the resulting dental composition has a pH in a range from about 5 to about 7.
