What is a dental crown

A dental crown is the common name for a dental prosthesis, a dental device that covers the prepared area of the tooth. The crown is ideally made of a durable material, such as metal or ceramic, used to cover at least two-thirds of the prepared tooth surface.Dental crowns are caps placed on top of damaged teeth. Crowns are used to protect, cover and restore the shape of your teeth when fillings don’t solve the problem. Dental crowns can be made out of metals, porcelain, resin and ceramics. They typically don’t require special care over time other than regular good oral hygiene.

There are many types of crowns that can be used on your teeth. Onlays and 3/4 crowns are types of dental crowns that don’t cover as much of your underlying tooth as traditional dental crowns. A traditional crown will cover your entire tooth. Onlays and 3/4 crowns may be appropriate when you still have a solid tooth structure. It’s considered a more conservative approach compared to full coverage of your crown. In this procedure, your dentist removes the affected area and performs a reshaping of the tooth to recMetal: There are several metals that can be used in dental crowns, including gold, palladium, nickel and chromium. Metal crowns rarely chip or break, last the longest in terms of wear down and only require a small amount of your tooth to be removed.

Porcelain-fused-to-metal: This type of dental crown can be matched to the color of the teeth that’s next to the crown. They have a more natural tooth color. However, sometimes the metal under the crown’s porcelain cap shows through as a dark line. Other cons include the chance of the crown’s porcelain portion chipping or breaking off and the crown wearing down the teeth opposite it within the mouth. This wear on the other teeth specifically affects the teeth that come into contact with the crown on the top and bottom of your mouth when it’s closed. Porcelain-fused-to-metal dental crowns can be a good choice for front or back teeth. (Source: my.clevelandclinic.org)

The costs of dental crowns can vary depending on where you live and the type of crown you pick. Porcelain crowns, for example, are typically more expensive than gold crowns, which are typically more expensive than porcelain-fused-to-metal crowns. In general, dental crowns can range in cost from $800 to $1,500 or more per crown. The cost of crowns is not usually fully covered by insurance. To be certain, check with your specific dental insurance company.Metals used in crowns include alloys that have a high content of gold or platinum, or base-metal alloys (for example, cobalt- chromium and nickel-chromium alloys).

Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color -- and the high price of gold -- is the main drawback. Metal crowns are a good choice for out-of-sight molars.Chipped crown. Crowns made of all porcelain or porcelain fused to metal can sometimes chip. If the chip is small, a composite resin can be used to repair the chip with the crown remaining in your mouth. This is usually just a temporary fix. If the chipping is extensive, the crown may need to be replaced. (Source: www.webmd.com)
