There does not appear to be any practical limits to the utter nonsense and pseudoscience that is invading health care. Apparently it's hip to be scientifically illiterate and pathologically gullible when it comes to "healing." Just when I think I've seen the worst of it something new comes along to push the envelope.  

Have you heard of "natural" or "holistic" dentistry? It seems to be just regular dentistry with an additional layer of marketable woo. Just put some organic wheat grass in your toothpaste you're practicing "natural" tooth care.  

The nonsensical height of holistic dentistry is the tooth-organ chart. This is yet another manifestation of the homunculus-based healing philosophy - the pre-scientific notion that the organs and other parts of the body somehow map to one particular body part, which is then the gateway to manipulating those body parts. Irididology holds that the iris of the eyes maps to the body, auricular acupuncture uses the outer ear, Korean hand therapy the hand, chiropractic the spine, and reflexology the foot.  

All of these belief systems are based upon the same homonculus model, and they are also all completely without any scientific basis. Despite centuries of anatomists dissecting the human body in great detail and exploring every connection, no one has ever discovered the alleged connections between these various body parts and the rest of the body. (I should note that the chiropractic subluxation chart does not correlate with actual nerve innervation.) There is simply no mechanism by which kidney disease would change the color in your iris or somehow connect to your outer ear or foot.  

Now I can add a new one to my list - the tooth organ chart. Did you know that your first molar on the upper left somehow connects to your liver, spleen, stomach and kidney?
