Authoritative medical organizations (outside of dentistry) have independently reviewed the scientific literature related to neurological, degenerative, autoimmune and psychological syndromes looking at dental amalgam as a causative agent – and found nothing:

• Alzheimer’s Association
• National Multiple Sclerosis Society
• Institute of Neurotoxicology and Neurological Disorders (Autism)
• American Academy of Pediatrics

Many organizations outside of dentistry have also reviewed the scientific literature looking for any credible link between dental amalgam fillings and general health problems – and have found none:

• U.S. Food and Drug Administration
• National Institutes of Health
• U.S. Public Health Service
• U.S.P.H.S. Centers for Disease Control and Prevention
• World Health Organization and European Commission

Two prospective clinical trials (7 years) compared the neurobehavioral, neuropsychological and renal effects in children receiving dental amalgam versus resin-based composites. No adverse effects were found in either study, other than a higher re-treatment rate for children with resin-based composite fillings.

Dental amalgam is effective – no true direct filling “substitute” yet exists


Amalgam fillings are considered less expensive to place and generally last much longer than any other material directly placed as a filling. While plastic fillings (composite) provide satisfactory service for approximately five years they are replaced at higher rates and repaired at twice the rate of amalgam. Collins et al, reported twice the failure rate for composites as compared to amalgam by the eighth year. By 10 to 11 years, failure rates as high as 40% to 50% have been reported for composites. More recently, multi-surface resin-based restorations were reported to be replaced and repaired at nearly twice the rate of amalgam restorations in 2,780 U.S. Navy and Marine Corps personnel during their first five years of service.

Dental amalgam is not a major source of environmental mercury


Less than one percent of mercury released to the environment from man-made sources comes from dentistry, according to the Environmental Protection Agency. First, the vast majority of mercury in surface water is from coal-fired utility plant exhaust that travels through the air then falls back to the  
earth. Second, very little amalgam enters surface water, because standarddental equipment and wastewater treatment facilities capture approximately 95percent of waste amalgam. The American Dental Association and dentists acrossthe country are committed to recovering and recycling amalgam. To furtherprotect the environment, the ADA encourages dentists to meet with localregulators and discuss what’s right for their community when it comes toamalgam waste disposal.

No state that has examinedthe issue has banned or limited dental amalgam!
