The present invention relates generally to the protection of a wearer of an installed dental appliance, such as braces, against pain, discomfort and injury due to the lips, cheek and tongue of the wearer rubbing against a rough or sharp edge of the braces. A dental protective device is used for protection against this discomfort and injury from the braces. The dental protective device is a moisture-activated self-adhering protective strip loosely adhered to a backing strip and packaged in a sealed foil pouch. In use, the protective strip is peeled away from the backing and applied to an area in need of protection.
