It has a mild bacteriostatic property as well which helps in decreasing the proliferation of Streptococcus mutans,...

Posted in Gold, Jewelry. If you’re thinking about selling a gold crown, filling, or old bridge, you may have wondered “Is dental gold real gold?”. The short answer is yes, as much as 67% of the gold in a dental crown could be real – although it is a bit more complicated than that.
As you may have already guessed, dental gold is not exactly the same as regular gold. Pure gold is very malleable, and is not ideal for use in the mouth, where the forces of chewing may deform the metal. For this reason, pure (24k) gold is not used for dental crowns or other dental work. Instead, an alloy of gold and other metals is used.
Dental gold is an often underestimated asset, but dental gold is in fact gold. Therefore, its value is based on the current gold price and the gold purity it contains. Do you know what happened to scrap dental gold from the 1970s – 1990s? Most scrap dental gold was not recycled; dentists and patients often just threw it away.
Dental gold, despite the name, is not always made of gold. This is one of the biggest risk factors associated with investing in dental scrap. Yellow gold dental scrap will often have a percentage of real gold. White dental scrap can be confusing, because it could either be very valuable or worthless.
Instead, dental gold is mainly comprised of an average of 16k gold alloy, which includes palladium, copper, silver, or tin. Together, these materials make for an incredibly durable dental implant, filling, etc., but sadly do not offer as high of a resale value as one may hope to gain from a single tooth.
Dental gold is rarely 100% pure gold. While the majority of dental scrap value comes from the gold content, precious metals are mixed in to increase strength and durability. Up to 30% of your dental gold could consist of platinum, palladium and silver. Most gold buyers pay only for the gold content (offering you nothing for the other metals).
That’s because some dental alloys contain gold and other valuable metals (typically platinum, palladium and/or silver). But at the other extreme, some are formulated with no precious metal content at all. Background – Dental alloy classifications. Dental alloys are divided into categories based on their level of precious metal content.
To perform this test to check if gold is real, make a light, tiny scratch on the item using a small nail file. Choose a spot that is not noticeable if possible. Use a dropper to apply a small drop of nitric acid to the scratch. If there is no reaction, then the piece is probably made from real gold.
