Abstract

Pre-shaped, non-custom dental trays (100) are either preloaded with a dental treatment composition (112), such as a bleaching gel, or filled with the dental treatment composition just prior to placement over a person's teeth. The pre-shaped dental tray (100) is thin and flexible, which allows it to be placed over a person's teeth and then approximately conform to the person's teeth. The pre-shaped, non-custom dental trays (100) can therefore perform similarly to a customized tray but without having to go through a lengthy customization procedure. A pre-shaped dental tray can be pre-loaded with a dental treatment composition and stored within a sealed packaging container (450).
