ADM Frostbite Endodontic Cryogenic Vitality Spray -55°C Frostbite now is even colder and can attain temperatures approaching -55°C. Frostbite comes in a larger can and is more highly pressurised to ensure a colder temperature when used. There are no chlorofluorocarbons used and the can and its components are fully recyclable. With Frostbite 248 there is no reason to bother with carbon dioxide systems. There are no bulky tanks or expensive parts to replace. Spray Frostbite 248 directly onto a cotton wool ball and place on a tooth with a pair of tweezers. Do not spray directly on a tooth surface.
