Composition and methods that include potassium nitrate for reducing tooth sensitivity and a dental bleaching agent, such as hydrogen peroxide or carbamide peroxide. The dental compositions (10) may be applied directly to the person's teeth (18), or they may be loaded into a comfortable fitting, flexible, thin-walled dental tray (22) and placed over the person's teeth (18). In that case, the dental compositions (10) will include a tackifying agent, such as carboxypolymethylene, which assists the composition (10) in retaining the dental tray (22) over the person's teeth (18) as a result of the adhesive properties of the dental composition rather than due to mechanical interlocking or fit of the tray over the person's teeth. The dental compositions may further include anticariogenic and antimicrobial agents. |
