The material in question, often referred to as amalgam, is a dental filling alloy composed of mercury, silver, tin, and copper. Its use in restorative dentistry has been widespread for over a century due to its durability and cost-effectiveness. Concerns regarding the mercury content have led to decreased usage in more recent times, but the cessation of its application is not a universal or absolute event.
Amalgam’s enduring popularity stemmed from its ability to withstand the forces of chewing and its relatively low cost compared to alternative filling materials. Its longevity in the oral environment made it a reliable option for restoring teeth damaged by decay. However, the visual contrast of silver amalgam with natural tooth structure, along with the potential for mercury release, has fueled debate and prompted the development of tooth-colored alternatives, contributing to a gradual shift in dental practice.
