Specific Symptoms of Dental Mercury Poisoning

Specific Symptoms of Dental Mercury Poisoning

Grinding or clenching one's teeth during sleep and at the moment of awakening

Metallic taste in the mouth (it tastes like the aluminum foil on chocolate)

Dark spots in the retina of the eye (Huggins, 1990) [1]; darker image in the affected eye. The subject may be unaware of his condition until he looks at the same image with one eye covered. One dental patient, Martin Dak, only learned about his condition at nineteen during a thorough eye examination. (The American Dental Association revoked Dr. Huggins's license in mid 1990's.)

Biting into one's tongue or lips when chewing tough food (very advanced illness).

Inability to fully open the mouth after prolonged chewing of very tough food, such as candy. This condition may last for 2 weeks (in Dak's case at the age of nineteen) and perhaps even longer. The patient can open his mouth only halfway. Clinical examination and X-ray images reveal no problem with the jaws. The reason for this condition is a sudden release of mercury from the fillings and the consequent convulsion of the jaw muscles. The patient may wrongly perceive that something is stuck at his temporomandibular joint and that his jaws are somehow locked. The condition develops overnight after the critical daytime chewing. The intensity of the condition diminishes very slowly, almost imperceptibly, and then, suddenly, everything returns back to normal.

The broken neck syndrome

The affected subject feels that he did not sleep right. He must have had some wild dream and somehow moved his pillow, and that is the believed reason for his pain in the neck. What is happening to him is convulsion in one of the two abductor muscles that connect the head with the collar bone. These muscles turn the head left and right, and also affect the up and down movement. The muscles run vertically in the posterolateral (back and sides) sections of the neck. When only one muscle is affected, the subject's head twists toward one side. When he tries to move his head the other way, he feels considerable pain at the collar bone. When both muscles are affected, the subject may feel global pain in his posterior lower neck and between and above his shoulder blades as he tries to bend his head down. The effects usually disappear within three days, but the next time the subject grinds his teeth during the sleep or chews hard food before going to bed, the same thing happens to him again.

The described symptoms may worsen after eating mercury-containing food (fish, shellfish) or chewing very hard food, or after a dental "restorative procedure" of the old fillings. The interaction between mercury amalgam and other dental metals (gold, steel, and titanium) commonly produces voltages of several volts and currents of several tens of microamperes. The voltages easily exceed the 0.7V firing potential of neurons, and erratic muscle jerking results. The subject's saliva and the metals in his mouth create a battery, and the electric current speeds up the release of mercury many times. The battery is "improved" by eating and drinking certain foods. Also temperature variations in the mouth affect the release of dental mercury into the body. In addition to the chemical impact, the electric currents produce their own harmful effects. These are discussed below.

Mental Effects

Electric currents may affect the operation of the entire cerebral hemisphere (in Dak's case, the left hemisphere was predominantly affected). Mathematical abilities, language production and comprehension, muscle control of the right side of the body, and interhemispheric communication can become severely disrupted. Drawing a clear line between the effects of mercury and electricity is difficult. Some of the believed effects of electric currents might be caused by mercury poisoning, or some deficits that appear to be associated with the left hemisphere might be attributable to the right hemisphere.

Poor muscle-eye coordination. This may become apparent only during typing or interactive sports and games. Inability to type by touch without looking at the keyboard.


Dyslexia (typing >>> tpying >>> tyipng)

Skipping over parts of a read text

When writing, omission of central portions of long words (transatlantic >>> translantic)

A word that is on the tip of the tongue and is believed to start with a specific letter almost always has the believed initial letter in the middle. For example, when you try to recall the name of a man whose name seems to start with an M, the man's name may turn out to be Thompson or Domhus, or Pembrook.

Occasional failure to register an entire spoken sentence

Frequent interruption of the short-term memory (sclerosis)

General difficulty socializing and interacting with people

Loss of interest in doing interactive activities (video games)

Difficulty tolerating bright light and sharp sounds (bright turn signals, sirens)

Difficulty processing sensory information quickly

Difficulty recalling well-known words/facts quickly

Inability to concentrate, easily distractible

Inability to exactly repeat a long sentence that someone just said. Difficulty with sentence repetition has been associated with lesions of the supramarginal gyrus [23].

Inability to process music by the left hemisphere

Inability to follow rhythm

Many manifestations of Wernicke's aphasia (reliance on the right hemisphere; preferable use of words that rhyme or produce internally perceived rhythm; poor semantic thought)

Difficulty spelling from memory, but easy spelling when writing or reading

Blurting out words in an incomprehensible way

General difficulty controlling one's tongue, lips, and vocal cords

Low ability to hear oneself speaking; poor registration or poor comprehension of one's speech

Difficulty with algebraic operations; loss, distortion, or confabulation of intermediate results. The subject is usually unaware of his or her problem. The only objective feedback is poor scores on a math test. The subject may be sure that he can solve the problems, because he is aware of his knowledge of the necessary mathematical procedures and can apply them correctly. But the subject rarely checks his work, and when he does, he is prone to overlook obvious mistakes. This results in poor test scores despite knowing the subject.

Difficulty remembering short articles, songs, or poems by heart, especially when they are not personally interesting

Difficulty remembering a series of items

Difficulty remembering personally unimportant information

Gradual loss of intellect and school performance (an early symptom)

Difficulty to grasp scientific concepts that others consider relatively easy

Learning to drive a car and driving in traffic can become very challenging

Reduced ability to solve problems

Suppression of all emotions

General feeling of inadequacy

Difficulty associating names with faces
Electrical stimulation from intracranial electrodes frequently disrupts naming of familiar faces [2].

Mercury poisoning can cause schizophrenia. The most frequent and probably easiest way to develop schizophrenia is to breath mercury vapors. This is one of the two main reasons that dentists have some of the highest suicide rates of any occupation. As for the second reason, you will have to read some more. Also Michael Faraday, a well-known physicist, developed schizophrenia by breathing mercury vapors. The development of schizophrenia from dental fillings seems less common than due to direct exposure to mercury vapors, but either type of mercury-caused schizophrenia tends to give the patient a puffy face.

Biological Effects

Dental mercury tends to concentrate in the brain and organs. This may cause global malfunction of the human organism.

Hypoactivity of all glands

Low production of hydrochloric acid in the stomach

Symptoms of malnutrition due to malabsorption

Foul-smelling stool, urine, and breath

Gas-filled floating feces



Chronic diarrhea, may last many months (advanced level of mercury poisoning)

Relative shortness of breath; may show only during sports

Frequent infections

Inflammation of the esophagus

Inflammation of the rectum, rectal itching

Occasional brief chest pain

Osteoarthritis throughout the body

Double vision or blurred vision. Poor depth perception. Poor dynamic range of vision. Some optical features may disappear when looking into a bright light. In high school, Dak failed to see the fine lines of a scale inside the microscope. All he saw was a fuzzy bright light, but nothing else. Similar difficulties exist in a poorly lit room when looking in people's faces against the window. The bright light coming from the outside makes the faces appear very dark, almost like silhouettes, and recognition of facial features is difficult.

Tingling in the fingertips

Shaky fingers

Loss of precise control in the fingers

General signs of multiple sclerosis

Low energy

Low sex drive

Erratic muscular responses

Constant muscle tension (due to electric currents in the mouth)

Eyes are "habitually" pulled to the left

Natural eyeblink reflex to moisten the eyes occurs very infrequently

Very poor balance, occasional vertigo. Pull toward one side when standing or sitting. Dak was told at 18 that he was leaning to his right side while sitting. Until then, he was unaware of his problem, which has bothered him ever since. When standing, he can feel a pull to the right and has difficulty telling whether his body is completely upright. When he starts writing a line of text by hand, the line gradually rises, and the end is typically about 1/4 inch higher than the beginning is. Only by carefully watching the paper, can he produce a horizontal line. An opposite deficit was seen in one of the "terrorist letters" shown on television. All the lines were dropping at about the same rate (1/4 inch per 6 inches of text).

Stiffness and/or paralysis in an entire side of the body (due to electric currents)
The right hand feels strong, slow, clumsy, and insensitive. The left hand is used preferably.

Slow responses to stimuli (early symptom)

Overall apathy toward stimuli

Dry eyes (an early symptom)

Liver malfunction and retention of water, especially in the belly and buttocks; later followed by the enlargement of breasts in males.

Strange pressure, as if swelling, in the pancreatic area (relatively advanced poisoning)

Poor tissue connectivity (ingrown toenails, separation of the skin from fingernails)

Receding, inflamed, and bleeding gum

Brown discoloration of the nails

Micro-cracks in the frontal surfaces of the incisors and deep longitudinal cracks in the incisors (layering of the incisors). Loss of bone mass inside incisors. The frontal surfaces may cave in and produce visible dips and deformation of the teeth. This condition is associated with partial loss of tooth enamel (the surface layer) and extreme sensitivity to cold, heat, and mechanical touch by fingernail or toothbrush. The tips of the incisors may become brown, fragile, and stop regenerating. Dark discoloration may occur along the vertical edges of the incisors. Just breathing at temperatures below plus 20 degrees C (about 70 degrees F) produces mildly painful sensation in the front teeth. The loss of bone mass is a consequence of nutritional deficiency resulting from damage to internal organs, especially the liver.

Damage to the teeth is only one of several degenerative symptoms. The teeth stop regenerating and gradually die from the tips. The incisors show this trend most prominently. The tips become thinner and deformed, but the teeth becomes thicker at the gumline. The tooth thickness may increase by 50%. The same problem affects the big toenails and is usually noticed years before the changes in the teeth are. The toenails become dead at the ends, have poor connectivity with the skin, and become about 2 to 3 times thicker than is normal. The toenails are dead as soon as they emerge from below the skin. An identical damage happens to the hair. The hairs begin turning white from the ends and gradually decay toward the follicles. Again, the follicles become thicker. Many die and cause inflammation. Some damage resulting from such deterioration is invisible. It can only be felt as stiff joints, loud cracking of joints during movement, and pain in the joints and surrounding muscles. Skelletal deformities, twisted limbs, and abnormal pull on muscles may develop over several years. Immobility and untimely death can be expected in such patients.

Longitudinal ridges on the nails (arthritis). Nails may become thin and flat between the ridges.

White spots in the nails

Brittle nails. Attempts to offset the damage with calcium supplements (even chelated calcium) may lead to severe calcification in the spine and pinching of nerves. Use only organic calcium in the form of milk and other plant or animal products.

Loss of toenails after long walks or hikes, blisters under nails. Often complete regeneration of lost toenails. Dak reports that he completely lost (gradually shed over the period of 4-6 months) and later completely regenerated his toenails on his big toes at least four times.

Symptoms of diabetes

Extremely low cholesterol level

Constant feeling of being cold, hungry, and sleepy

Low body temperature (35.0 to 36.0 degrees Celsius); freezing in the summer

Inability to digest food; what goes in comes out intact

Waking up exhausted after a 10- to 12-hour sleep

Leg kicking during sleep

Arm jerking during rest or sleep

Excruciating contraction of toes after prolonged exposure to cold (early symptom)

Excruciating contraction in the calf muscle, about 5 to 8 cm (2 to 3 inches) below the knee. This condition typically occurs during rest that follows strenuous walks or jogging and is exacerbated by cold.

Yeast infection throughout the digestive tract; constant intestinal micro-tremmors

Vaginal yeast infection

Feverish, burning, cracking and bleeding lips

Persistent or recurrent redness in the face (advanced illness)

Enlarged capillaries in the white of the eye

Frequent collection of mucus in the throat, especially after waking up

Substantial loss of mucus (intestinal lining) in feces

Stuffy nose

Ear infections; fluid buildup and clogging in the ear canal

Partial deafness

Ringing in the ears

Frequent nose bleeding or dryness in the nose in dry climate

Polyps in the nose and mouth

Painful, swelling eyeballs

Discolored spots and "blisters" in the white of the eye (advanced effects)

Clogging and swelling of the outlets of salivary glands inside the mouth

Sticky tongue due to dryness in the mouth

Extreme allergies to pollen and household chemicals; frequent sneezing

Unavoidable sneezing after looking directly at the sun

Allergies to car travel when the fan is running (due to pollen in the air)

20 to 25 attacks of diarrhea per day after taking antibiotics

Low heart rate during the day (52-54 beats per minute) and especially before falling asleep (46-48 beats per minute) at the age of 15 years; an early sign

Alzheimer's-like symptoms; recovery may be possible. Documented by Tom Warren in his book about his personal experience. Information about this dental patient is on the internet.

Skin bumps, hard nodules, or finger-like formations in the skin (the fingers can be 2-3 mm in diameter and up to 6 mm long)

Overall weight gain and puffy face

Permanent occurrence of many freckles after a few days in bright sunshine. (Weak immune system).

Abnormal findings of proteins in the urine (relatively advanced stage of poisoning)

The patient's body may produce toxic sweat; bed sheets may dissolve

Internal bleeding (blood in the stool, urine, ejaculate, and phlegm)

Susceptibility to jock itch and athlete's foot; fungal infections

A pea-sized nodule at the thyroid gland develops overnight and lasts several weeks

Painful swelling of glands (testicles and thyroid)

Blue palms, hands, and feet when temperature drops below ~20 degrees C (advanced illness)

Numerous dark-red capillaries just under the skin of the feet; advanced illness

The head is spinning after making a somersault (intense tingling/burning sensation spreads from the navel toward the pubic region)

Destruction of brain tissue due to electric currents in the mouth. During examination at the dentist's office, a current of 41 microamperes was measured between a place under Dak's tongue and his golden crown. Later that day, Dak repeated the measurement himself and obtained a reading of 120 microamperes. To put these numbers in perspective, here are a few examples of how electric current affects neural tissue in the brain. Direct current of 1,000 microamperes applied for 20 seconds causes lesions in the dorsal hippocampus of the rat [4]. Shi and Davis produced lesions in the insular cortex of the rat by passing direct current of 1,000 microamperes for 10 seconds [6]. Just 500 microamperes applied for 10 seconds can reliably destroy amygdaloid nuclei in the brain of the rat [3]. Li and Pan produced marking lesions in the rostral ventrolateral medula of the rat by means of mere 50 microamperes applied for 30 seconds [7]. Of course, a dental patient cannot limit the current in his or her mouth to a few seconds. The currents vary in magnitude, but flow at all times. Interestingly, electric currents that are needed for proper operation of the human body tend to be no more than a couple microamperes [5].

Allergies after liver damage. Inability to fall asleep due to splitting headache in the forehead. Substantial reduction in the intensity of the headache after standing up, but the headache spreads to the parietal and occipital lobes, and sometimes even to the lover jaw. Within an hour, the subject may hyperventilate, lose his muscle control with the lower jaw and the whole body shaking. The subject is feeble and may feel that he may collapse to the floor. Within seconds, the subject vomits, which is how most of these attacks are resolved. After vomiting, the headache is often gone almost immediately, but mild fatigue usually last even after waking up in the morning.

Food allergies vary over time and daytime; most strike just after going to bed. The worst allergies are produced by a combination of exposure to pollens and certain foods. Some of the bad foods are: lamb, pears, peaches, salmon, eggs, and peanuts.

Allergy and splitting headache can also be triggered by household chemicals, sudden change in weather from dry to rainy, or from hot to cold, or from calm to windy. Viral and bacterial infections may also lead to the same condition. The headache can last for many hours, sometimes even two or three days. The remedy can be incredibly simple. Dissolve one tea spoonful of baking soda (sodium bicarbonate) in a cup of warm water. Drink the solution. You should feel better in seconds. Drink another cup of the same solution, and the headache should completely disappear within minutes. But beware of carbonation. Too much pop is not good for your intestines. You may produce gasses if you overdo it.

The headache is associated with poor pH balance. Baking soda restores the digestive environment closer to normal. Baking soda may not work when the headache is relatively mild or is caused by factors other than indigestion. Vinegar has also been reported as helpful in treating this condition. Both baking soda and vinegar are weakly acidic. This is a paradox, because the overall sensation during the headache is one of acidity, and citrus fruits (particularly oranges), which are supposed to be acidic, frequently cause the headache. So, the issue is more complicated than appears on the surface.

Cure for cirrhosis is unknown, but detoxification of the liver does benefit the poisoned dental patient. Dramatic loss of extra weight may occur within 2 to 4 weeks and continue for several months until the patient's weight is restored to near normal. Detoxification also significantly reduces the symptoms of arthritis. A great improvement may occur in mental clarity (due to the disappearance of encephalopathy caused by poisonous byproducts in the brain) and in the overall level of energy. Sleep requirement may drop from 12 hours to 9 hours per day. Two essential non-prescription pills are available. According to internet search results, neither is known to have any side effects.

MSM natural organic sulfur (methylsulfonylmethane): removes mercury from the body.
Extract from milk thistle seed (silybum marianum): repairs and detoxifies the liver.

A common produce, red beet, reportedly also cleanses the liver.

Note: Some individuals may be sensitive to larger doses of milk thistle taken before sleep. More than 1 pill (about 400 mg) may lead to very unpleasant smooth-muscle contractions or chemical imbalance and awakening. Males with enlarged breasts due to liver damage may experience dramatic breast reduction overnight, but in the evening, the breasts become big again. This is another reason to take only one pill at a time, but several times a day.

Behavioral Indicators

Loss of intellect results in strong adherence to habits.

Loss of emotions results in indifference to the suffering of others.

Global body shaking when staying in one position for too long (either standing or sitting).

Inability to sleep on one's side (due to electric currents and a loss of balance)

Keeping one's head below the blanket during sleep to preserve body heat

Wearing thick sweaters in the summer

Craving sugar and foods high in energy

Inattention to semantic, personally unimportant things (very poor observation talent)

Difficulty recalling one's duties, assignments, homework, and priorities at the right time

Watching TV, movies, and school lectures so that eyes look to the left

Special Symptoms

Brainstem damage. Many of the above problems occur in patients with brainstem damage. Sinha reports that indicators of brainstem infarction are the following: vertigo, dizziness, sensation of ear canal blockage, slurred speech, clenching and grinding of teeth, double vision, and leaning to one side when standing or sitting [8]. Damage to the brainstem can also be deduced from Dak's experience. He reports that the day he began mercury detoxification, he started having between 1 and 3 dreams per night with no night without a dream for full 6 months. Dreams are usually associated with brainstem activity [9].

Seeing circles is a strange symptom that has been experienced by Dak since early teens, at which time he already had mercury amalgam fillings. When he closes his eyes and fixes his vision at one spot, as if looking through his eyelids, he can see black and white imagery. On the blank background, he can distinguish tiny circles that look like micro-bubbles floating haphazardly before his eyes. Within a few seconds, some of the circles rapidly join together and form a single vertical string that starts to oscillate from side to side around one of the anchored ends of the string. This phenomenon is usually transitory and cannot be sustained for more than a few seconds, but can be evoked repeatedly and at any time. The string of circles is between about 8 and 12 mm long. The typical string length is about 10 mm. The circles can vary in size and numbers from barely perceptible to almost 1 mm in diameter. They all seem to move at constant speeds, roughly a few millimeters per second. The freely floating bubbles can be viewed for tens of seconds. At some point, there is a sudden rush as a few adjacent bubbles start hopping on top of each other to build the string from the bottom upward. It is not possible to tell where in the swarm of circles the buildup will start, but when the string is fully formed, it appears to be positioned at the center of the visual field. The actual oscillations of the string only last between 1 and 3 seconds, and then the string disappears. The other bubbles can be seen even thereafter.

Seeing crossed needles is another odd visual phenomenon experienced by Dak in connection with his mercury fillings. When his eyes become tired and he wipes them, he can see 2 crossed sets of about 4 or 5 regularly spaced black-and-white needles in each set. The needles are similar in shape to the needles of a spruce. The imagery lasts a second or two and usually cannot be reproduced soon after the experience. At least several minutes of rest must be allowed to evoke the phenomenon again. The needles, like the circles, are grayish outlines, rather than bright-white or dark-black images. There is no color. The needles at the center are about 10 mm long, while the needles at the edges are shorter, about 7 mm long. Each needle is about 1.5 mm wide at its center and becomes narrower toward the ends. The spacing between the needles is about the same as the width of each needle (1.5 mm). The group of needles is never vertical or horizontal, but always occurs at an angle of about 45 degrees. A second group of 4 or 5 needles comes at 45 degrees from the other side and forms with the first group a complex pattern similar to the letter "X". Interestingly, the two groups of needles never intersect or blend directly. One set of needles runs its full length, but the opposite group of needles stops when it approaches the other group, and continues on the other end of the "X" pattern. Dak only started seeing this imagery shortly after the removal of his mercury amalgam fillings. Similar "X" patterns are well-known to be caused by damage to the visual system.

Many of the above problems occur in patients with brainstem damage. Sinha reports that indicators of brainstem infarction are the following: vertigo, dizziness, sensation of ear canal blockage, slurred speech, clenching and grinding of teeth, double vision, and leaning to one side when standing or sitting

Developmental Effects

A pregnant woman with mercury amalgam fillings runs a high risk that her fetus will be malformed. The more fillings she has and the more chemically active her fillings are, the more mercury her fetus receives. Mercury fillings that are in contact with other metals, or root canal that is filled with mercury amalgam (common dental practice) is particularly dangerous. The consequences may be:

Malformed skeleton (chest, jaws, and other parts)

Abnormal teeth (missing, misplaced, malformed, too big, or too small)

General brain damage

Sensory defects

A study conducted by the World Health Organization in Calgary, Canada in 1989 found substantial damage to the liver and kidneys in experimental sheep and monkeys. Mercury was found in the brains of the fetuses of the pregnant sheep (Vimy, 1989).
