High Noble (Gold) Crowns

The best gold restorations are a high-noble alloy, meaning that at least 60% of the crown is made up of gold and other precious metals like platinum, palladium, and silver that are noted for their low-reactivity with human tissue and resistance to corrosion and oxidation.

Gold has been used for a long time in dentistry, and for good reason. Gold is extremely durable and has the least reactivity of all the metals in the mouth. It is also extremely gentle on the opposing teeth and is especially well-suited for molars in patients who clench or grind habitually. Gold remains strong and durable even when it is thin, allowing for more conservative crown preparations and the preservation of more healthy tooth structure. Additionally, gold works beautifully with glass ionomer cements that are often far less sensitive for many patients than the bonding techniques required for full-porcelain crowns.
