The Brain-Mouth Connection. 6 Systemic Implications

Written by Mark A. Breiner, DDS

What happens in Las Vegas stays in Las Vegas! Unfortunately, what happens in your mouth doesn’t stay in your mouth. There are systemic implications in this article. I will limit the discussion just to the effect on one’s brain.

1-The so-called silver fillings are approximately 50% mercury. This Mercury comes off the fillings as a vapor, its most dangerous form. Mercury goes to every cell, bypassing the blood-brain barrier and going directly into your brain. Remember the Mad Hatter from Alice in Wonderland? Mercury was used in making felt hats in the 19th century, and many workers developed neurological symptoms, thus the term “mad as a hatter.” Mercury is a highly potent neurological poison, and the fact that mercury fillings are still used, I feel, is criminal. A word of caution: if you want to remove your Mercury fillings, ensure someone knows how to do it safely and correctly.

2- The CDC estimates that about 47% of adults 30 years and older have some form of periodontal disease, and for people 65 years old and up, the percentage is approximately 70%. A large number of studies have shown that a person is at higher risk of heart disease, respiratory illness, stroke, dementia, and Alzheimer’s disease if they have periodontal disease. This is why good home care is critical and why we take a plaque sample from under the gums and look at it under the microscope. Things are not always as they seem; sometimes, the gums can appear healthy, but the plaque sample shows otherwise. Large numbers of bacteria, especially of the wrong variety, may be evident, thus alerting us to potential problems. I’ll never forget a patient who could no longer run his business because of his mental incapacity. His daughter was now running the company and brought him in for examination. He presented with severe periodontal disease. With a whole-body approach that addressed the unhealthy situation in his mouth, his cognitive ability was restarted, and he resumed control of his business.

3-Fluoride is a toxic poison. Fluoride should not be added to our drinking water. This is mass drugging without any scientific justification. How do you justify giving the same dose of any drug to an infant as to a 200-pound man? Supposedly, this drug is given to reduce tooth decay; however, it has never been shown that fluoride in drinking water has that effect! However, it does have other effects, one of them being lowering a person’s IQ. Hundreds of studies give testament to this. If it has this effect on the mind, what else can it do? If one looks into the homeopathic Materia Medica, which shows the symptoms related to fluoride, mentally, there is indifference to one’s spouse and children as well as depression and sadness. Adding fluoride to the drinking water is not suitable for people, but it’s good for drug companies. The Fluoride Action Network is in a lawsuit with the EPA concerning fluoride and its effects by placing it in our water supplies. It is amazing how our government, which supposedly works for us, will do everything it can to block getting the truth out!

4-Electrical currents in the mouth can affect the brain. When you place different metals in the mouth, you create a battery. Mercury fillings are 50% mercury; the other half is copper, tin, zinc, and silver. Now, place titanium implants and crowns made of various metals such as gold and nickel into the mouth with mercury fillings, and you have a sea of electrical currents. Sometimes, these currents are enough to interfere with brain activity. After removing their mercury fillings, patients often comment that things look brighter, their mood is better, and they can think more clearly.

5-Root canals can have many adverse systemic effects, one of which is on the nervous system. A root canal is a chronically infected dead tooth that contains potent toxins that can affect any susceptible organ or tissue. Studies conducted over 25 years by Dr. Weston Price showed that root canals affected the nervous system. Among the effects were paralysis and interference in mental activity.

6-Every tooth is on an acupuncture meridian and relates to different organs and tissues. Thus, a problem in a tooth’s brain function can have adverse consequences. For example, the upper wisdom tooth relates to the pituitary gland. If this tooth is impacted, it may negatively affect the pituitary gland, causing hormonal problems and thus affecting one’s mood.

This short article helps you see how intimately the mouth is related to proper brain function. The above topics would need a lengthy article to fully explore their effect on the brain and all the other relationships to one’s health.
