About bleaching tray blanks
Bleaching tray blanks are thin, soft sheets, mostly EVA, formed over a model of the teeth to make a custom bleaching tray. EVA is a thermoplastic copolymer that can be easily adapted with heating.
In at-home tooth bleaching, a low-concentration material is dispensed in a custom bleaching tray. Custom appliances are made from sheets by thermoforming over a model of the patient's teeth, typically by vacuum forming or pressure forming.
What to look at when choosing
Reservoirs: reservoirs are modifications in the tray mould that increase the amount of bleaching material the tray carries. In a randomized trial, reservoirs did not improve colour change or affect tooth sensitivity and gingival irritation.
Size and gauge: sheets are listed by thickness, by shape (5 inch square or round) and by pack count.
