A dental crown is a versatile restoration that has many uses in dentistry. Commonly known as caps, crowns cover up the entire visible part of a tooth. The crown protects the tooth against bite forces, acids, and bacteria in the mouth while restoring its appearance.Crowns can be made from a variety of materials, but porcelain…
What Materials Are Dental Crowns Made Of?
There are various types of dental crowns patients can choose from to restore the size, shape, function and appearance of a damaged or weakened tooth. Each type of material has its own benefits and potential disadvantages to consider, and the best option may strongly depend on the purpose of the crown and the tooth it is intended to protect.
Types of dental crown materials
There are several different types of dental crown material options for patients to consider so that they can get the most effective and appropriate treatment for them personally. The more common types of dental crowns include porcelain-fused-to-metal, all-metal, gold and ceramic.
Porcelain-fused-to-metal dental crowns are the most commonly recommended option by many dentists. This is because they combine the best elements of both metal and porcelain. They are stronger than porcelain crowns, but they also blend in with natural teeth better than metal crowns. They work well for front and back teeth. However, the drawback to porcelain-fused-to-metal crowns is that they are not as strong as metal crowns and the metal portion may partly show while smiling.
Metal or gold crowns
Metal and gold are the most durable material used for dental crowns. Metal crowns can be comprised of different types of metal alloy, including chromium and nickel-chromium. Gold crowns are even more durable than metal-alloy. They both offer superior durability and can withstand pressure from chewing well, so they work great for teeth further back in the mouth. However, metal and gold crowns are more noticeable as they are different than the natural shade of teeth, so they may not be the best option for teeth that are more visible.
Porcelain or ceramic crowns
Ceramic dental crowns are most appropriate for teeth towards the front of the mouth as they can match the shade of natural teeth. However, they are not as durable as metal crowns or porcelain-fused-to-metal crowns, so they will not hold up as well over time if they are placed on teeth that are used more for chewing and crushing food.
How to choose the best option
Each type of dental crown offers unique benefits, and the type that works best depends on the treatment goals and the tooth (or teeth) that needs the crown. Porcelain-fused-to-metal is often the most recommended type of dental crown as it is an ideal combination of quality appearance and good durability.
When durability is the primary concern, metal-alloy or gold dental crowns are likely more preferable, whereas ceramic crowns are often the most appropriate for patients whose issue is primarily cosmetic. Ultimately, the best way to decide is to discuss all options with a general dentist.
