For a permanent tooth that has been reimplanted after avulsion or is very loose from extrusion, you can form a splint using periodontal paste. Mix equal parts base and catalyst and place on a tongue depressor in water. Dry the patient's teeth and gingiva using gauze and air through a Yankeur or nasal cannula. Either wet your gloves or cover in lubrication. Roll the paste into a cigar shape. Gently press into the teeth and gingiva, splinting to at least one stable tooth on either side. Allow paste to dry.
