Oral-Cal Mouth Rinse

Oral-Cal Mouth Rinse is an 8 oz bottle of a Calcium/Zinc solution that will make up to 32 ounces of solution.

  • clean and soothe the mouth tissues,
  • reduce bleeding of gums,
  • desensitize teeth,
  • strengthen teeth and their ligaments
  • and strengthen the oral bone.

Regular use of the Oral-Cal Mouth Rinse reduces plaque, stains, bad breath, calculus, sensitivity, decay and soothes canker sores or similar gum irritations.

Furthermore, routine use of the Calcium/Zinc Toothbrush with the Oral-Cal Mouth Rinse as a brushing agent, or with Calcium Carpules, whitens tooth structure.

Instructions for Use [See the Video]:

Active ingredients calcium and zinc ON THE INSIDE RIM OF THE BOTTLE.

NOTE: Be sure to use bottled water, since water quality varies. Also don’t touch the spout with your mouth during use. Rinse the bottle out with clean water between fillings.

  1. Fill with bottled water.
  2. Close the spout and cap TIGHTLY and set the bottle UPSIDE DOWN on the cap.
  3. Let it set for 6 (six) hours before using.
  4. For a brushing agent add several drops in front of the tongue and brush.
  5. In either case, brush, rinse the brush, and empty the mouth, but do NOT rinse out the remaining residue in your mouth. Let this soak into the mouth tissues, teeth and bone.
  6. Once the bottle is empty, rinse out with clean water before refilling and turning the bottle upside down again.
  7. Keep refilling the bottle until there is no more calcium on the rim.
