The theory underlying craniosacral therapy is erroneous because the bones of the skull are fused to each other, and cerebrospinal fluid does not have a palpable rhythm. Auriculotherapy is a variation of acupuncture based on the notion that the body and organs are represented on the surface of the ear. Proponents claim it is effective against facial pain and ailments throughout the body. Its practitioners twirl needles or administer small electrical currents at points on the ear that supposedly represent diseased organs. Complications from unsterile and broken needles have been reported.
Some dentists claim to specialize in the treatment of bad breath.
Such dentists have no special expertise and are primarily interested in increasing their income by selling unproven products. The active ingredient is chlorine dioxide, which is also used as an algaecide in swimming pools. There is no scientific evidence to support this assertion or the diagnostic and treatment methods based on it. Proponents of this dubious theory have formed the American Academy of Biological Dentistry. A few hundred dentists claim that the mercury in silver-amalgam fillings is toxic and causes a wide range of health problems, including multiple sclerosis, arthritis, headaches, Parkinson's disease, and emotional stress.
