Gold Dental Crowns

Dental crowns are used for a number of reasons. Your dentist may recommend one due to loss of tooth structure or root canal treatment. You might also choose one for cosmetic improvement of your smile. 

There are many different types of crowns used to restore a tooth. Among those are gold crowns, which have been used in dentistry for a number of years.

Materials

In dentistry, there are three main categories of crowns, all metal crowns, all porcelain crowns, and porcelain fused to metal (PFM).

Gold crowns are a type of metal crowns. There is the option for a full gold crown made entirely of gold or a gold alloy. A gold crown may also come as a PFM, which is made from a combination of gold and porcelain.

In regards to the gold, three types of alloy are used for fabricating gold crowns:

• High Noble Alloy (Precious Metal): Made from a minimum of 60 percent high noble alloy. This includes gold, platinum, and palladium. If a crown uses a combination of these alloys, at least 40 percent must consist of gold.
• Noble Alloy (Semi-Precious Metal): A noble alloy consists of 25 percent precious metal.
• Non-Noble Alloy (Non-Precious Metal): Made from less than 25 percent precious metals, noble alloy generally is made from a combination of nickel, chromium, and gold.

Benefits

There are many reasons why your dentist may recommend a gold crown. For instance, gold crowns are able to withstand heavy forces from chewing and may be recommended if you exhibit heavy wear patterns on your teeth.

Additionally, these crowns are less susceptible to chipping or breaking, making them a long-lasting dental restoration. If a tooth with a gold crown breaks, it is generally because the underlying tooth structure has fractured or decayed. However, gold crowns may become loose, especially if you are eating foods and candy that are harmful to crowns and bridges.

Gold crowns also cause the least wear on the opposing tooth. For patients that grind their teeth or who have a heavy bite, a gold crown will typically cause the same amount of wear on the teeth, compared to the tooth's natural enamel. 

Since they do have a yellow or white gold color, gold crowns are used primarily to restore molars and premolars. Some people request gold crowns on their front teeth as well. This choice is often more of a fashion statement that was popularized by well-known rappers.

Allergies

If you have a metal allergy, such as a nickel allergy, make sure your dentist is made aware of it before a gold crown is fabricated. A high noble alloy that contains no nickel or other common metals that cause allergic reactions should be used carefully in these cases.

Cost

Many dentists have a specific base price for all of the crowns they offer their patients. However, because gold is a very expensive alloy, a gold crown may cost more than a porcelain crown. The increased cost is generally reflected in the laboratory charge, not your dentist's fee.

A Word From Verywell

Gold crowns are an excellent choice for patients who are not necessarily concerned about having an entirely white smile. Gold crowns are, in fact, an attractive restoration and offer long life. If you require a crown, speak to your dentist about the different crown options that are available.
