Abstract: A dental x-ray film preferably includes a dental x-ray casing adapted to be removably positioned within the patient mouth, an x-ray film contained within the dental x-ray casing, a protective cover removably positioned over the dental x-ray casing such that the dental x-ray casing and the x-ray film are completely contained within the protective cover. Such a protective cover is preferably formed from flexible fluid-impermeable material. A dry powder is preferably coated on a major surface area of an outer surface of at least one of the protective cover and the dental x-ray casing. Notably, the dry powder is fluid-soluble and includes an anesthetic agent and/or a flavoring agent capable of providing a numbing effect and a desirable taste when exposed to fluid, respectively, during the dental x-ray procedure.
