Patent ID: 6964571

Claim:
A dental treatment device comprising: a pre-shaped, non-custom dental tray suitable for placement over at least one of a person's upper or lower dental arches, wherein the dental tray is formed from a thermoplastic material and comprises: at least two side walls defining a trough and having a substantially horseshoe-shaped configuration at least approximately corresponding to a person's dental arch, wherein the at least two side walls are substantially devoid of structures corresponding to the size and shape of a person's unique dentition so that the dental tray is designed to fit over a plurality of differently-sized dental arches corresponding to different people, wherein the at least two side walls have a thickness less than about 1 mm and are flexible so that, when the non-custom dental tray is placed over a person's teeth, the tray can at least partially conform to the person's teeth during use in order to approximate the comfort and fit of a custom dental tray without the need to formally customize the tray; and a quantity of a dental treatment composition loaded within the trough of the dental tray, the dental treatment composition being sufficiently viscous and sticky so that, when the dental tray is placed over a person's teeth, the dental treatment composition will hold and retain the dental tray over the person's teeth and cause the tray to at least partially conform to the person's teeth.
