Metal dental crowns are made entirely from metal. Different metals that are used to make this type of crown are gold, platinum, copper, cobalt-chromium, and nickel-chromium. These are an ideal choice for replacing molars because they are very durable and not visible. Some downsides are that they have a metallic appearance and that they corrode over time.
- Porcelain-Fused-To-Metal Dental Crowns
Porcelain-fused-to-metal dental crowns (PFM crowns) have a more natural tooth color. This is ideal for those who need a strong replacement tooth, but don’t want the metallic look. They also cost less than a full porcelain crown, but they could cause wear on the other teeth and at the gum line, you may be able to see a grey line from the metal that is under the crown
- All-Porcelain Dental Crowns
All-porcelain or all-ceramic dental crowns are made from porcelain and ceramic materials. There is absolutely no metal in these types of crowns, so it is the perfect choice if you are allergic to any kind of metal. These give the look of a real tooth, but they are not as strong as the metal or PFM crowns and they have been known to wear done the teeth that are above it.
All-resin dental crowns are made from resin. This dental crown type is the most affordable and they can be color-matched to look like your other teeth. Even those this choice is cost-effective, they are not ideal as a long-term solution. They are not as strong as the other types of crowns and wear down over time.
Zirconia is a newer material that is used for dental crowns. They have become a more popular choice lately because of their strength, durability, and aesthetic appearance. They can also be cut in the same dentist’s office where your procedure is taking place, making it a less time-consuming process.
