IAOMT Fequently Asked Questions about Biological and Mercury Free Dentistry

What is biological dentistry?
Biological dentists recognize the impact of toxic materials and relate it to dental and physiological health. These dentists are concerned with the integrity of the oral cavity and use materials and procedures in their practices that are systemically compatible.

Is there a concern about the use of mercury in dentistry?
Many people do not realize the "silver" amalgam fillings are 50% mercury. A large filling may contain as much mercury as a thermometer. Mercury vaporizes easily at room temperature, and in this state, is odorless, colorless and tasteless. Inhaled mercury vapor is readily absorbed into the bloodstream. The World Health Organization has concluded that dental fillings contribute more mercury to a person's body than all other sources of mercury combined. Mercury is a powerful poison. Published research demonstrates that mercury is more toxic than lead, cadmium or arsenic. No amount of exposure to mercury vapor can be considered harmless. Especially considering its cumulative effect.

Is there an associated health risk?
Mercury is the most toxic, non-radioactive element on the earth. Most medical and scientific researchers have called for a ban on the use of mercury in all products. However, the potential harmful effects of mercury fillings have been ignored by the U.S. Government. Due to its poisonous nature, mercury can adversely affect the immune, urinary, cardiac, respiratory and digestive systems. Under laboratory conditions, mercury has produced brain cell deterioration identical to that seen in victims of Alzheimer's disease.

Should I have my mercury fillings removed?
The IAOMT believes you should (unless you are pregnant or lactating). Mercury vapor is continuously emitted from dental fillings and accumulates in the body over time. The damaging effects of this exposure may not manifest for years or even decades. Studies repeatedly demonstrate that even low levels of mercury cause measurable adverse health effects. Mercury in the tissues of a fetus or infant correlates significantly with the number of dental amalgam fillings in the mother. Newborns may be at risk for learning disabilities because of mercury their mother absorbed during pregnancy. Many physicians are testing their patients for mercury toxicity and referring them to biological dentists. Across scientific disciplines, health professionals are realizing that mercury may adversely impact patient health.

Should I take supplements prior to mercury filling removal?
Most biological dentists work in conjunction with physicians, who may prescribe supplements prior to the removal of mercury fillings. It is imperative that chronically ill patients seek advice from a physician knowledgeable in mercury toxicity issues.

Is there a proper way to remove mercury fillings?
To prevent additional mercury exposure, find a biological dentist properly trained in mercury filling removal. Patients should inquire about the following amalgam removal protocols:

• Utilizing an efficient suction system in the oral cavity with a special tip or its equivalent to contain amalgam particles and mercury vapors.
• Operating a vacuum system at maximum efficiency.
• Applying copious amounts of water to the filling during removal.
• Removing the amalgam in large segments to minimize the generation of mercury vapor and amalgam particulate.
• Providing the patient and dental staff with a mercury-free source of air.

Where can I find a dentist trained in these techniques?
The IAOMT is a group of dentists, physicians and researchers involved in peer-reviewed scientific research, education and the promotion of biological dentistry. The IAOMT encourages the use of biocompatible materials and the development of appropriate protocols to ensure whole-body patient health. The tenets of a good dental practice should be based on peer-reviewed research - not on conventional wisdom. Most importantly, the materials and procedures used in dentistry should not adversely affect the rest of the body. Dr. John Johnson, DDS is a proud member of the IAOMT.

The IAOMT and its members are very concerned about excess exposure to mercury when old amalgam fillings are removed. The process of drilling out amalgam fillings liberates quantities of mercury vapor and fine particulates that can be inhaled and absorbed through the lungs. We have developed some simple methods for reducing this exposure, which all members of the IAOMT should be aware of. Accredited members, Fellows and Masters are all certified as being proficient in safe amalgam removal techniques. For more information, see the article, “Safe Removal of Amalgam Fillings” in the Featured Articles section of this website.

If your dentist is not an Accredited IAOMT member, ask these questions:

What is your position on the mercury issue? How much knowledge do you possess about mercury?
If a dentist is knowledgeable about the mercury issue and understands mercury biochemistry, it is likely they will take the removal process seriously. Be concerned if you hear, "I don't think the mercury in fillings is a big deal, but I'll take it out if you like. This is probably a dentist that isn't very concerned about removal protocols.

Do you use a rubber dam when removing amalgam?
The rubber sheet greatly reduces the amount of particulates that go down the throat.

Is your suction system powerful and efficient? Do you use a special tip (such as "Clean Up," available from IAOMT) or its equivalent?
Utilizing an efficient suction system in the oral cavity with a specialized adaptor or its equivalent is necessary to contain the mercury vapor and amalgam particles.

Do you apply copious amounts of water to the filling upon removal?
Large amounts of water help contain the mercury vapor and fine particulate matter, as well as, cool the filling.

Do you remove the mercury/amalgam filling in large sections?
By using a very thin bur and reducing the amount of drilling, the amount of mercury and fine particulates is minimized.

Do you utilize alternative air sources and/or equipment to reduce mercury inhalation?
The dentist should employ one or more methods to prevent the patient from inhaling the mercury vapor and fine particulate matter.
