SUBTANTIALLY SOLID DENTAL BLEACHING COMPOSITIONS IN A TRAY-LIKE CONFIGURATION AND KITS AND METHODS THAT UTILIZE SUCH COMPOSITIONS

摘要

Dental bleaching compositions (10) are in the shape of a dental tray or traylike configuration (12, 14, 16). Shaped bleaching compositions (10) comprise a substantially solid dental bleaching composition that has increased adhesiveness to teeth when moistened with saliva or water. The shape of the dental bleaching composition (10) facilitates placement of the composition (10) over a person's teeth with substantially less manipulation compared to the use of initially flat bleaching strips. The substantially solid dental bleaching composition (10) becomes more adhesive when moistened with saliva or water, yet remains intact and coherent after the dental bleaching composition (10) is placed over a person's teeth during bleaching, particularly when used in combination with a moisture-resistant barrier. The result is that the moistened dental bleaching composition (10) is able to reliably adhere against a user's teeth during a bleaching procedure. The dental bleaching compositions (10) may be packaged together as a kit, optionally in combination with one or more dental desensitizing composition in the shape of a dental tray or having a tray-like configuration.
