A dental tray molding kit for making a custom dental tray includes a generictray, a thermoformable member removably insertable into the generic tray and adeformable spacer member placeable onto the thermoformable material andbiteable by the user upon placement of the spacer member onto thethermoformable member in the mouth of the user. The generic tray may be arigidcarrier tray and the kit may further include a partially deformable member tobeplaced between the rigid carrier tray and the thermoformable member. A methodfor dental tray molding includes providing a generic tray, heating athermoformablemember until it is sufficiently pliable, placing the thermoformable memberover thegeneric tray, placing a deformable spacer member over the thermoformablemember, applying a biting force from a user onto the thermoformable memberthrough the deformable spacer member, cooling the thermoformable member andseparating the thermoformable member, whereby the thermoformable memberforms a custom dental tray.
