Mercury-Safe Dentistry


We practice mercury-safe dentistry.

The safety of amalgam fillings represents an increasingly controversial topic in world dentistry.   

  • All amalgam fillings contain 48-52% mercury, depending on brand, even those placed across America today.  Other metal components are copper, silver, tin, and zinc.
  • Mercury is the most neuro-toxic, non-radioactive element on the planet, more neurotoxic than arsenic or lead.
  • Dental researchers now concede that mercury vapor is released from unstimulated amalgam fillings 24 hours a day.  They do not agree on what this vapor release means for an individual's health.  Debate centers on (1) how much mercury vapor is actually released and (2) how efficiently different individuals bind and eliminate emitted toxins.
  • For some people, signs and symptoms of mercury posioning begin almost immediately upon exposure.  These individuals are said to be allergic to mercury; they are not genetically predisposed to eliminate neurotoxins and heavy metals efficiently.  Other individuals may experience an insidious onset of symptoms months or years later, and it is impossible to relate symptoms conclusively to amalgam fillings.  Still others are genetically predisposed to eliminate neurotoxins and heavy metals with considerable efficiency and seem to function well with amalgam fillings for a lifetime.
  • Chewing, brushing, temperature increases (hot liquids or foods), professional tooth polishing (if hygienist does not avoid amalgams), and clenching/grinding have been shown to stimulate the emission of mercury vapor.  There is substantiated scientific evidence that 80% or more of inhaled mercury vapor enters the bloodstream.  From the bloodstream, mercury is distributed throughout the body and stored in organs, glands, and tissues, rendering detection difficult through traditional hair, blood, or urine analysis. 
  • Some mercury toxicologists conclude that no amount of human exposure to mercury vapor has been found to be harmless. 
  • The FDA and the American Dental Association promote amalgam fillings as standard of care dentistry.  Dentists who place amalgam fillings do so in good faith, believing in the efficacy, safety, cost-effectiveness, and longevity of amalgams.  
  • Sweden, Austria, Denmark, and Norway have all banned amalgam fillings. 
  • In the United States, on June 4, 2008, the FDA reversed its previously pro-amalgam safety stand to warn on its website: “Dental amalgams contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses.”  The FDA revoked its 2008 warning in 2009.  


So...  Does the amount of mercury released into your body affect your health?




You must do your own research and draw your own conclusions. 


Regardless of which side of the amalgam-safety controversy seems most reasonable to you, our goal as dental providers is to offer the safest possible replacement as old amalgams break down. 


Dr. Lou, Dr. Wendy, and Dr. Matt are all accredited by the International Academy of Oral Medicine and Toxicology ( for mercury-safe dentistry. Dr. Matt also strictly adheres to the IAOMT's safe amalgam replacement protocol, and he is currently completing his accreditation.




 Meetinghouse Dental Care is also certified S.M.A.R.T. by the International Academy of Oral Medicine and Toxicology.




For OUR Safety


For us, exposure to ambient mercury is an occupational hazard.  Our rubber-based masks have two filters, an outer one to trap mercury particulates that can lodge in our lungs during amalgam-removal and an inner one to filter mercury dust and vapor.


For YOUR Safety


A NARROW, ROUND-TIP BUR sections old amalgam fillings in the largest chunks possible to reduce release of mercury vapor, particulates, and dust.


A NOSE HOOD with unidirectional continual-flow fresh air supply protects your nasal breathing space.


The ISOLITE INTRA-ORAL PROTECTOR connects directly to the high-speed vac to pull mercury vapor, particulates, and dust from your oral breathing space.  (We also have Clean-Ups. )  (Clinical trials indicate that mercury vapor passes through the latex rubber dam during mercury-amalgam removal .  The vinyl rubber dam provides more protection.)


Copious use of OZONATED WATER during amalgam removal suppresses mercury vapor, particulates, and dust, trapping amalgam debris in the Isolite suction system.  We also use ozonated water in our lines.


USP FOOD-GRADE, COCONUT-SHELL, ACTIVATED CHARCOAL SLURRY is processed to meet purification standards required for medical use.  Charcoal absorbs toxins, drugs and poisons from the human body.  Charcoal rinse/swallow prior to amalgam removal coats the oral mucosa and tongue with tasteless black powder to prevent absorption of mercury debris into soft oral tissues and the digestive tract.  (The slurry also absorbs birth control pills, antibiotics, chronic disease medication, etc. ingested two hours prior or two hours post.  To avoid charcoal absorption of prescription drugs, rinse only.  Charcoal does not absorb vitamin or mineral supplements.)


An ORA-SHIELD DENTAL DAM NAPKIN drapes facial skin.


LG-2 IONIZERS from AESI-Air Defense in the ceiling of each restorative operatory capture mercury debris that escapes the Isolite.  LG-2 Ionizers create a continuous electrophoresis effect, negatively ionizing ambient particles to drive them toward positively-charged field collectors that render them inert electrically.  LG-2 Ionizers have been shown to reduce recordable ambient mercury levels to zero instantaneously.  (LG-2 Ionizers have also been shown to trap and neutralize airborne and blood borne pathogens, bacteria, pollen, allergens, hydro-carbons, and elemental metals.  They neutralize particles too small for HEPA filters, even to .001 micron.) 


The flexible, self-supporting suction arm of the IQAIR DENTAL HG (MERCURY) FLEXVAC positions near your head to capture mercury vapor and particulates, reducing measurable ambient mercury debris (as well as drill aerosols, VOC’s, formaldehyde, glutaraldehyde, dust, viruses, bacteria, and microbial contaminates) to nearly zero. 


Meticulous maintenance of equipment maximizes the efficiency of our technology, and we use ozonated water in our lines. 


As post-removal protocol, we apply MEDICAL-GRADE OXYGEN-OZONE to the preparation site in the tooth from which we have removed decay in order to kill bacteria, fungi, and viruses prior to restoration. (Dr. Trovato is a certified participant in the national outcome study conducted by the American College of Integrative Medicine and Dentistry on dental applications of medical grade oxygen-ozone therapy.  Meetinghouse Dental Care is a registered research facility.  Medical-dental oxygen/ozone creates a therapeutic oxygen-rich environment that induces a multi-factorial positive biochemical/physiologic change in affected tissues.)


POST OP MOUTH RINSE options include charcoal, chlorella, and sodium ascorbate with N-Acetyl Cysteine.


Finally, we protect the environment with the AMALGAMBOSS MERCURY SEPARATOR installed on our wastewater lines.  The AmalgamBoss extracts and contains mercury-amalgam fragments before they are released into the public water system.  Pennsylvania does not yet require amalgam separators for dental offices, but approximately 64% of the mercury load on city wastewater management comes from dentistry.  The AmalgamBoss tests at a 99%+ capture rate to keep municipal sludge mercury-free.  (NOTE:  Research indicates that some 20 tons of mercury would not be discharged into the environment annually if every dental office had a separator installed on its water lines.)


We strive to maintain a quiet electromagnetic field as well.  We know mercury-compromised individuals can experience heightened sensitivity to EMF’s.  We’ve installed Stetzerizer GS-F110-A Filters and a Four Leaf Energy IC Unit to minimize the overall electromagnetic field.  Every fluorescent overhead light fixture has been converted to cleaner energy; ballasts/transformers are completely severed and mercury-free LED’s replace fluorescent tubes.  Grounding pads from on each operatory chair minimize bioelectric stress from dental technology.


If you are sensitive to EM fields, ask us how to reduce potential electromagnetic field pollution in your sleeping space while you undergo the process of dental revision.  Did you know, for instance, that an extension cord beneath your bed emits a constant electromagnetic field, even when all appliances are turned off?  If you experience insomnia due to EMF sensitivity, especially if you have silver fillings or metal crown or bridge work, eliminating the electromagnetic field around your bed can provide healing sleep to your overloaded central nervous system.  Investing in a grounding sheet for your bed ( can also provide relief.


When existing amalgam fillings are mechanically intact, it must be your personal choice to have them replaced with other materials, whether for health or aesthetic reasons


Replacing any filling material, for whatever reason, involves drilling out existing material, cleansing and drying the exposed area, and placing new materials.  A tooth that starts comfortable - especially if it contains an amalgam filling that is deep or larger than the remaining tooth structure - can be rendered sensitive or even painful during the replacement process, regardless of replacement material chosen or skill of your dentist.  If a tooth has been traumatized in the past, or if decay beneath the existing filling has drawn too near the nerve, it will become necessary to decide between (1) root canal therapy with oxygen-ozone to kill bacteria, virus, and fungus (root canalled teeth present their own health challenges to the body) or (2) extraction.  Patients with health issues and patients under the direction of biologic health practitioners may opt for extraction.  Upon rare occasion extraction may be required.


Finally, whether clinically necessitated or elective, removing amalgam fillings will produce a transient increase in a person’s exposure to mercury.  We minimize exposure to guest and team through physical barriers and advanced technology.  As mercury burden is removed from teeth, however, the body will begin to release certain amounts of stored mercury into the bloodstream in anticipation of elimination from the body.  That is, the body will retoxify in the process of detoxifying.  You must have your paths of elimination - liver, gallbladder, kidneys, skin, lymph - open in anticipation of this natural process.   A person who is mercury-toxic or sensitive may experience an increase in both physical and emotional symptoms for an unpredictable period of time following amalgam removal.  Nutritional and metabolic precautions can be taken, especially to support the paths of elimination.  If you believe that you are mercury toxic or sensitive, we suggest consultation with a nutritionist/naturopath/integrative MD/other health practitioner experienced in mercury toxicity. 







When I was looking for an alternative dentist, I had specific requirements due to my former mercury poisoning from my dental fillings.  First, it had to be a professional that did NOT use any toxid mercury in their practice and one that truly understood the neurological and neurocognitive damages that mercury causes humans.  Dr. Trovato uses composite fillings and is also well aware of tjhe different materials available for durability and color preferences.  He si very open to ciocompatibility presferences in the type of anesthesia and composite materials used.  I also enjoy the willingness that Drs. Loua nd Barb Trovato provide in securing material samples for biocompatiblilluyt testing, in addition to respect for one's time in that they never keep you waiting more than a few minutes.  Meetinghosue Dental Care employess are warma nd friendly and clearly display job satisfaction.  Mettinghosue Dental Care is that unique, Ia mwilling to drive 45-50 minutes for my appointments.

Dear Dr. Trovato: Words are so inadaquate when it comes to thanking you for all the extraordinary dental care and kindness that you and your staff gave to me last Thursday.  In my many years of going to dentists, I have never had such a painless, comfortable, almost enjoyable experience in the dental chair.  Your expertise with the state-of-the-art equipment you use, plus your patient answering of my questions, was so appreciated.  I have never had such a thorough oral exam in my life, and all that you did to my teeth was awesome.  I enjoyed meeting Anthony, the nutritionist, and he was very informative and helpful in what he taught me.  Barbara and your staff are so thoughtful and friendly, and I really felt like I was with caring family.  It was also a pleasure meeting Dr. Jose Alvarez.  Although I traveled five hours each way to come to your office, it was truly an honor to be there, and the distance did not matter.  I look forward with joy to my next visit.  In the meantime, thank you again for the BEST dental experience of my life!

Jeanne Ann Greist, Mansfield PA
