An enclosure useful in enclosing a dental X-ray film pack upon taking an X-ray picture of a tooth is formed of an enclosing portion and a holding portion extending from the enclosing portion. To permit enclosure of a dental X-ray film pack provided with a bite block, the enclosing portion is formed of two separate sheets. After inserting the bite block into a basal part of the holding portion, the pack is covered between the two sheets and the two sheets are then fusion-bonded to seal the pack within the enclosing portion. The holding portion has a length sufficient to extend out of an oral cavity when the enclosing portion is inserted in the oral cavity. After taking the X-ray picture of the tooth, the dentist holds the enclosure at the holding portion, takes the enclosing portion out of the cavity, and then tears off the enclosure from a side of the holding portion, so that the dental X-ray film pack falls out of the enclosure. The dentist is therefore free from the potential danger that the patient's saliva may stick to him.
