Background: Dental amalgam has been a cornerstone in restorative dentistry for over 165 years due to its versatility, durability, and cost-effectiveness. Despite the ongoing debate surrounding its safety and health implications, dental amalgam remains widely used for its long-term performance in restoring teeth. Objective: This review aims to evaluate the effectiveness of dental amalgam as a restorative material in terms of longevity, durability, and impact on oral health outcomes. The study also seeks to explore the various types of dental amalgam available and their unique properties. Conclusion: Recent research indicates that high-copper dental amalgams can provide satisfactory performance for over 12 years, even in large restorations. While concerns exist regarding the potential health risks associated with mercury in dental amalgam, numerous studies have shown minimal release during placement and removal. Various types of dental amalgam, such as resin-coated, fluorinated, and bonded amalgams, offer additional benefits in terms of clinical performance and longevity. Overall, dental amalgam continues to be a valuable option for restoring teeth, contributing to caries prevention, tooth preservation, and maintaining oral health. The decision to use dental amalgam should be based on a thorough assessment of individual patient needs and considerations.
