Why Gold Is Still Used in Dentistry (and How Pure It Really Is)
Gold might seem like a relic of the past, but in dentistry, it remains one of the most reliable and long-lasting materials for dental restorations. From crowns to bridges, gold alloys continue to offer unmatched durability, biocompatibility, and precision — making them a smart choice for patients who value longevity and oral health.
Why Dentists Still Use Gold
1. Gold Is Incredibly Durable
Gold dental crowns can last 20 to 50 years or more, outperforming many modern materials like porcelain or composite resin. Its resistance to wear and fracture makes it ideal for molars and patients with heavy bite forces Garfield Refining. AZoM Materials Science
2. It’s Biocompatible and Safe
Gold is chemically stable and doesn’t corrode in the mouth, making it one of the most biocompatible materials available. Unlike some base-metal alloys, gold doesn’t release reactive ions that could irritate tissues or cause allergic reactions ddsdentalimplants.com. PubMed: Biocompatibility of Dental Alloys
3. Gold Offers a Precise Fit
Gold’s malleability allows dental technicians to craft restorations with microscopic precision, ensuring tight margins that reduce the risk of microleakage and secondary decay Garfield Refining.
4. It’s Gentle on Opposing Teeth
Gold wears similarly to natural enamel, meaning it’s less likely to damage the opposing tooth — a major advantage over harder materials like zirconia DentaGama.
5. It Preserves More of Your Natural Tooth
Because gold is strong even in thin layers, dentists can remove less tooth structure during preparation, helping preserve long-term tooth integrity DentaGama.
How Pure Is Dental Gold?
Contrary to popular belief, dental gold isn’t 24-karat. Pure gold is too soft for chewing forces. Instead, dentists use custom alloys that combine gold with other metals like platinum, palladium, silver, and copper to enhance strength and durability ddsdentalimplants.com Ivoclar Academy Gold
Typical Composition
Dental gold alloys typically contain 60–78% gold, depending on the type and application. According to industry standards, dental casting alloys must contain at least 75% noble metals, with 65% of that being gold ddsdentalimplants.com.
FAQs About Gold Crowns
