Types of Dental Amalgam

  • Low-Copper Amalgam: Traditional type, which has about 5% copper.
  • High-Copper Amalgam: More commonly used today, with 13-30% copper, offers better durability and resistance to corrosion.

Properties and Benefits

  • Durability: Extremely strong and long-lasting, often lasting 10-15 years or more.
  • Wear Resistance: Withstands the forces of chewing.
  • Cost-Effectiveness: Generally less expensive than composite fillings.
  • Ease of Application: Simple to place, hardens quickly, and is less sensitive to moisture during placement.

Preparation and Placement

  1. Tooth Preparation: The dentist removes the decayed portion of the tooth.
  2. Mixing: The mercury and alloy powder are mixed to form a pliable amalgam.
  3. Placement: The mixed amalgam is placed into the prepared cavity.
  4. Condensation: The dentist packs the amalgam tightly to eliminate air pockets and ensure a good fit.
  5. Carving and Polishing: Once set, the amalgam is carved to replicate the tooth’s natural contours and then polished to reduce roughness.

Controversies and Safety

The use of mercury in dental amalgam has led to debates regarding its safety. Major health organizations, including the American Dental Association (ADA) and the World Health Organization (WHO), assert that dental amalgam is safe for most people. The mercury in amalgam is bound within the material, significantly reducing the risk of mercury exposure. However, certain groups, such as pregnant women, children, and people with kidney disorders, are advised to avoid dental amalgam when possible.
