If you have had a root canal, your dentist will likely recommend that you get a crown over the tooth. The reason to do this is that your tooth is going to need to be protected because the root canal will have weakened it. Putting a crown on it will also disguise any kind of damage or decay as well. There are several materials that a crown can be made of, and what one gets used in your situation depends on where the tooth is located in your mouth, how much use that tooth will get, and other variables. So, what are some of the materials that a dental crown could be made out of?
Metal is most commonly used when it comes to teeth that aren't going to be seen. If you have a molar that no one is going to see, your dentist may suggest that you go with metal because it can stand up to a lot of use, and since no one is going to see it, the fact that it is metal isn't going to be a drawback. The metals used can include gold, nickel, and palladium.
If you are worried about any kind of metal allergies, make sure that you talk to your dentist and tell them your worries because they may be able to switch what metal they were going to use. For example, if you have a nickel allergy, your dentist would want to make sure that they don't use nickel or anything with a nickel alloy.
2. Porcelain-Coated Metal
These crowns are made out of the same metal as a metal crown would be, but instead of having the bare metal as a finish, the crown has dental porcelain fused to the outside. The porcelain can be tinted so that it matches the rest of your teeth, so it works well in a visible place in your mouth. The dentist may actually go with a shade that is slightly brighter than the rest of your teeth because the metal can cause the porcelain to look a little darker than it really is. The metal is durable, but the porcelain might chip during use, so you will have to watch for that.
If you are going to get a crown, your dentist is going to tell you about all the different kinds of materials that they can use. There are a lot of variables that go into deciding which one they will use for you.
