What Materials Are Commonly Used To Make Dental Crowns?
Posted on: 16 July 2021
Dental crowns are dental caps that are used to cover damaged teeth. Crowns protect the natural teeth by preventing further damage that otherwise may result in tooth loss. They are used to cover teeth that are cracked or chipped so that the damaged areas are no longer visible. These are some of the different materials that are commonly used to make dental crowns.
Metal Crowns
Metal dental crowns are usually made of gold, nickel, palladium, or chromium. Metal crowns are considered to be one of the strongest types of dental crowns because they can easily withstand biting and chewing and are rarely damaged with normal use. However, metal crowns are going to be the color of the particular metal they are made of. Therefore, many people prefer to only have metal crowns placed over their back teeth so they are less noticeable.
Ceramic or Porcelain Crowns
Dental crowns can also be made of ceramic or porcelain material. These types of crowns are often preferred because the color of the crowns can be easily matched to the natural teeth of the patient. This makes the crowns less noticeable so that they are even suitable for covering damaged front teeth. Ceramic or porcelain dental crowns are not as durable as metal crowns and may eventually need to be replaced.
Resin Crowns
Resin dental crowns are made completely out of resin and can be created in colors to match the natural teeth. However, resin crowns are not quite as strong as metal, ceramic, or porcelain dental crowns and will most likely need to be replaced over time. Because of this, resin crowns are also usually less expensive than other types of dental crowns.
Porcelain Fused to Metal Crowns
Another option that patients have are porcelain fused to metal dental crowns. These crowns are made of a metal base that fits over the natural teeth and is covered and sealed with porcelain to create a more natural appearance. These dental crowns are strong and durable, but it is possible for the porcelain finish to chip away over time.
When dental crowns are being installed, the damaged teeth need to be filed and shaped to fit snugly inside the crowns. A dental cement is used to seal the crown to the natural tooth so that it will remain in place. Regardless of which material is used for dental crowns, the damaged teeth are better protected from being further damaged than if no dental crowns are installed.
