Dental Amalgam Debate
Historical Use and Effectiveness
Many dental professionals favor amalgam for posterior restorations due to its strength and longevity. Research has consistently supported its reliability, especially in patients with high caries risk or limited access to dental care (Berry et al., 2014).
Health and Safety Concerns
Opponents of amalgam use argue that mercury exposure, even in small amounts, poses health risks. Mercury is a known neurotoxin, and some worry about its potential accumulation in the body. (U.S. FDA, 2020). Public pressure and environmental safety concerns have fueled further debate.
Environmental Considerations
Amalgam waste, when improperly handled, can contribute to environmental mercury pollution. Dental clinics must now comply with regulations requiring amalgam separators to reduce waste discharge into water systems. Environmental agencies advocate for reduced mercury usage globally under the Minamata Convention.
Support for Continued Use
Despite concerns, many experts argue that amalgam remains a valuable material in dentistry. It is more tolerant of moisture than composites and less expensive, making it essential in underserved populations. Studies continue to show no conclusive evidence linking amalgam fillings to systemic health issues in the general population (Gordon & Mjor, 2015). Informed consent and proper patient selection remain key to its ethical use.
