Mix ¼ teaspoon of Medi-Dental Pack powder in a nonmetallic container. Add a small amount of aloe or purified water to create a clay ball. Next, place this clay ball inside your mouth and form it around the tooth or gum area you wish to cleanse. Hold the ball in place for 5 to 7 minutes. Finally, remove the ball and rinse your mouth with purified water. (If you happen to swallow a small amount of the clay mixture, it is harmless.)
