Abstract
A dental tooth whitening material sets to a rubber-like or elastomeric consistency. The material includes hydrogen peroxide. A method of whitening teeth employs such a material by placing it into a dental tray, a backing sheet or by placing the material directly onto a tooth. Once the material has set to its solid or semi-solid consistency, the dental tray, if employed, can be left in place or removed.
