1. 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;

    a bottom wall having a substantially horseshoe-shaped configuration corresponding to at least one of person'"'"'s upper or lower dental arches,a front side wall extending laterally from a front end of the bottom wall;

    a rear side wall extending laterally from a rear end of the bottom wall; and

    a hollow interior portion defined by the bottom wall, front side wall, and rear side wall;

    wherein the bottom wall, front side wall, and rear side wall 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 comfortably fit over a plurality of differently-sized dental arches corresponding to different people,wherein the bottom wall, front side wall, and rear side wall have a thickness in a range of about 0.05 mm to 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 hollow interior portion of the dental tray, the dental treatment composition being sufficiently thick so that, when the dental tray is placed over a person'"'"'s teeth, the dental treatment composition will hold the tray over the person'"'"'s teeth and cause the tray to at least partially conform to the person'"'"'s teeth.
