Gold Dental Restorations

Gold alloys have been used in dentistry for centuries and are still considered by many professionals to be the benchmark for dental restoration longevity. Dental gold is not pure gold but rather an alloy containing gold, platinum, palladium, silver, copper, and other metals in varying proportions. These alloys are classified as high noble, noble, and base metal depending on their precious metal content. Gold restorations offer numerous clinical advantages including exceptional marginal adaptation, wear rates similar to natural enamel (protecting opposing teeth), resistance to corrosion and tarnish, and longevity often exceeding 20-30 years. Gold inlays, onlays, and crowns are fabricated using the lost-wax casting technique, allowing precise reproduction of tooth anatomy. Despite their superior functional properties, gold restorations have declined in popularity due to aesthetic concerns and the increasing demand for tooth-colored alternatives. Rising gold prices have also made them more expensive. However, gold remains an excellent choice for posterior teeth in patients who prioritize longevity over aesthetics, and gold is still used in some implant frameworks and precision attachments.
