Our Plush Hot and Cold Wrap provides relief from pain, swelling, stiffness, and limited range of motion. One side of this gel therapy pack is covered with ultra-soft, plush material, to provide immense comfort and relaxation. It also features a loop strap at each end, for holding the pack in place. Wrap it around the jaw line and tie the straps on top of the head, to reduce swelling after dental procedures. Microwave or soak the pack in hot water for hot therapy and freeze for cold therapy. It has been tested for CPSIA, FDA, and TRA (Toxicological Risk Assessment) compliance and approved that it is flexible and non-toxic.
