Abstract

Dental bleaching devices (10) in the shape of a dental tray or tray-like form include an outer barrier layer (18) and an inner bleaching layer (20). The shape of the dental bleaching device (10) facilitates placement of the device (10) over a person's teeth with substantially less manipulation compared to the use of initially flat bleaching strips. The bleaching layer (20) comprises a substantially solid dental bleaching composition that becomes more adhesive when moistened with saliva or water, yet remains intact and coherent after the dental bleaching device (10) is placed over a person's teeth during bleaching. Because a substantial portion of the dental bleaching composition remains solid or semi-solid during bleaching, the bleaching composition maintains a substantial portion of its adhesive properties and internal cohesive strength. The dental bleaching devices (10) may be packaged together as a kit, optionally in combination with one or more dental desensitizing devices in the shape of a dental tray or having a tray-like configuration.
