Health Improvements Related to Amalgam Filling Removal & Mercury Detoxification: By Dr. Tom McGuire

Amalgam Filling Removal and Symptom Improvement

This section will be extremely valuable to you if:


  • You now have mercury amalgam silver fillings and want to know how your health may improve if you have them removed
  • You’ve already had these fillings removed and want to know the benefits of participating in a mercury detoxification program
  • You have any symptoms or diseases related to mercury amalgam fillings 

Symptom Improvement Chart

This chart is a compilation of studies organized by Sam Ziff of Bio-Probe, Inc. A total of 1569 patients participated. We’ve arranged the results to emphasize the Percentage Improved or Cured, highlighting those symptoms most improved solely from the removal of mercury-amalgam fillings. The other columns also yield important data. For example, the Percentage with Symptom and the Total Number of Symptoms columns show that the most common symptoms related to mercury-amalgam fillings in this particular study are fatigue, headaches, vision problems, and depression. But as you can see, it covers a vast array of mercury related symptoms. 



Before and after the removal of their mercury amalgam fillings, patients were evaluated for the symptoms listed in the chart. Allowing for minimal variables, the only constant was that all participants had their amalgam fillings removed. It is common sense that if a symptom wasn’t related to mercury poisoning, it wouldn’t show improvement after the fillings were removed. 

Amalgam Filling Removal & Symptom Improvement

Percentage with Symptom Symptom Percentage Improved or Cured Number Improved or Cured Total Number of Symptoms
6 Lack of energy 97 88 91
17 Metallic taste 95 247 260
8 Gum problems 94 121 129
5 Anxiety 93 80 86
22 Depression 91 315 347
8 Irritability 90 119 132
14 Allergy 89 68 81
22 Dizziness 88 301 343
6 Bloating 88 70 88
5 Chest pains 87 69 79
34 Headaches 87 460 531
10 Irregular heart beat 87 139 159
45 Fatigue 86 603 705
12 Ulcers (oral cavity) 86 162 189
10 Nervousness 83 131 158
8 Muscle tremor 83 104 126
15 Intestinal problems 83 192 231
8 Numbness anywhere 82 97 118
17 Lack of concentration 80 216 270
12 Insomnia 78 146 187
7 Multiple sclerosis 76 86 113
17 Memory loss 73 193 265
29 Vision problems 63 289 462
6 Blood pressure problems 54 53 99

In our opinion, the extent of symptom improvement was primarily related to the length of time the individual was mercury toxic, the amount of damage mercury had done to the general body and central nervous system (CNS), the participant’s overall health at the time of removal, the health of the immune and detoxification systems, and the amount and kind of any supplementation a participant was taking. 


For the purposes of this article, the “general body” includes every part of the body except the Central Nervous System (CNS).

Amalgam Removal: Health Observations Before and After

Another excellent study, Health Observations Before and After Amalgam Removal by Dr. Paul Engel, a Swiss dentist, showed significant improvement in a number of health issues directly related to chronic mercury poisoning. All of the patients tested had been treated in his practice, and once he became aware of the health hazards of mercury amalgam fillings he encouraged his patients to have them safely removed and replaced with a healthier dental filling. The purpose of the study was to determine which symptoms existed prior to amalgam filling removal and which ones improved after removal. Again, the improvements recorded were solely the result of mercury amalgam filling removal. Other than any supplements a participant may have been taking before or after amalgam removal, none of the patients participated in a standardized mercury detoxification program. 



Seventy-five patients (52 women and 23 men) were evaluated, all having one or more of the 53 symptoms that were evaluated. The symptoms ranged from 36 complaints of migraines to one case of diabetes. Those with the greatest number of complaints are shown below: 

Symptoms Prior to Amalgam Removal     

Migraine 36
Headache 32
Gastro-intestinal problems 27
Neck tensions 25
Paresthesia 19
Dizziness 18
Allergies 13
Vision disturbances 13
Back pain 12
Mental disorder 12
Joint pain 10
Shoulder/arm pain 10

After the amalgams were removed, all of the participating patients rated changes to their health as follows: 

Percent of Subjects Reporting Changes Due to Filling Removal

Mercury Detoxification Program & Amalgam Removal: Related Health Improvements

A study assessed by Linda Jones, Dental Amalgam and Health Experience: Exploring Health Outcomes and Issues for People Medically Diagnosed with Mercury Poisoning, evaluated 35 people who had previously been told that their symptoms, including cognitive deficits and mood swings, were psychosomatic. The most common conditions they expressed were chronic fatigue syndrome (CFS), candidiasis, allergies, migraines, and chronic or recurring flu symptoms, all of which can be related to chronic mercury poisoning. Of the 32 who had begun amalgam removal, 29 reported enduring health gains. Of the 30 who had completed both amalgam removal and a mercury detoxification program, 21 experienced a full return to health and the activities of daily life. Eight others in the study reported recovering from the symptoms they attributed to mercury, but now had either a new problem related to detoxification or a pre-existing condition that didn’t improve. Only one person following the protocols experienced no lasting improvement. The three who hadn’t begun amalgam removal were still ill and felt that they were deteriorating. 


Another study by Lindh and associates looked at improvements in symptoms and quality of life of 776 people who had their mercury amalgam fillings removed and participated in a mercury detoxification program. The subjects suffered from an array of symptoms related to chronic mercury poisoning; including those related to general, neurological, psychiatric, and oral health. More than 70% of those who completed both removal and detoxification reported a substantial recovery and increased quality of life. 


Though not everyone got completely better and not every symptom was eliminated, each of these studies showed a high percentage of improvement in symptoms related to chronic mercury poisoning for those who had their amalgam fillings removed and participated in a mercury detoxification program.

Mercury Detoxification and Health Improvements Related to Chronic Mercury Poisoning

The studies described above dealt mainly with improvement in symptoms. The next logical step is to evaluate improvements in specific illnesses. Thanks to a recent DAMS (Dental Amalgam Mercury Syndrome) project, detailed information is now available. The DAMS group evaluated over 1000 peer-reviewed and government studies that showed mercury as the cause or major factor in over 40 chronic health conditions. They also reviewed over 60,000 cases of amalgam removal and replacement showing evidence of cure or significant improvement in numerous chronic conditions, as documented by treating health professionals. Note that this study wasn’t conducted by pro-amalgam dentists.



While the study didn’t include a detailed breakdown, it indicated which symptoms and diseases can be most improved by removing amalgam fillings and participating in a mercury detoxification program. While each disease had a relationship to chronic mercury poisoning, the extent of the disease, the individual’s state of health and factors such as genetics, diet, and environment affect the positive outcome of amalgam removal and mercury detoxification. This table shows conditions that significantly improved after amalgam replacement: 

Type Symptom or Disease that Improved
Autoimmune disorders Arthritis, multiple sclerosis, Lou Gehrig's Disease (ALS), Parkinson's disease, muscle tremor, Alzheimer's, muscular and joint pain, fibromyalgia, Crohn's disease, lupus, scleroderma, chronic fatigue syndrome (CFS), endometriosis, diabete
Neurological (including mood disorders) Memory loss, depression, schizophrenia, insomnia, anger, anxiety, mental confusion, neuropathy/paresthesia, tinnitus, dizziness/vertigo, headaches/ migraines, epilepsy, ADD, autism, dyslexia, learning disabilities, hearing loss.
Oral disease Periodontal diseases, oral lichen planus, amalgam tattoos, metal mouth, halitosis, oral keratosis (pre cancerous).
Immune system disorders Allergies, asthma, multiple chemical sensitivities, eczema, psoriasis, other skin conditions, susceptibility to infections, antibiotic resistant infection, sinus problems.
Cardiovascular conditions Tachycardia, angina, arteriosclerosis, hypertension, and other blood conditions.
Hormonal conditions Hypothyroidism, adrenal problems, chronic chills, Hashimoto's disease, alopecia/hair loss, urinary/ prostrate problems, depression, suicidal thoughts.
Reproductive disorders Infertility, reduced sperm counts, PMS, spontaneous abortions, birth defects, developmental disabilities, children with learning disabilities and low IQ.
Eye Conditions Inflammation, iritis, astigmatism, myopia, cataracts, macular degeneration, color blindness, vision disturbances.
Stomach/digestive problems Leaky gut, candidiasis, malabsorption of essential minerals and essential fatty acids, blocked cellular enzymatic processes related to the ATPASE energy function and sulfur oxidation.

What Does It mean to You?

In these studies, the majority of people who took no other action than having their amalgam fillings removed experienced improvement in a significant percentage of their symptoms. It was also shown that participating in a mercury detoxification program after filling removal resulted in more significant health improvements. 


It’s my opinion that safely removing these poisonous fillings and participating in a mercury detoxification program should be regarded as essential treatment for chronic mercury poisoning. We also believe it is the only way you can determine which health effects are related to chronic mercury poisoning and which result from other factors.
