When are crowns used?
Crowns are used whenever the top portion of a tooth has been damaged or compromised in some way. If a tooth is chipped or broken, a crown can be attached to cover and protect the tooth and give the appearance of a healthy set of teeth. If a tooth has had several fillings or if a root canal has been performed, Dr. Nair may choose to place a permanent crown over the top of the tooth to prevent any more damage.
If a person chooses to have a dental implant put in place, the top portion of the implant will be a full crown or artificial tooth that is attached to the top of the post.
What are crowns made of?
Crowns are made of many different types of materials. In the past, gold or silver-based crowns were extremely common. They were permanent and lasted for many years with little wear.
Today crowns made of dental grade porcelain are the most common. They look and feel just like a natural tooth and will not discolor over time.
Ceramic and plastic resin are also used to make temporary crowns. Ceramic crowns are mostly used for root canals and to create the top portion of dental implants.
You may choose a long lasting, but less expensive crown for any back teeth that wouldn’t usually show when you smile.
What is the difference between a temporary crown and a permanent crown?
The main differences between a temporary crown and a permanent crown are the type of materials used and the amount of time they’re expected to remain in place. They’re not an exact fit like a permanent crown, but they serve the purpose of protecting the tooth until the permanent crown is ready to be installed.
Temporary crowns are normally made of a lighter weight material that’s not as durable, such as ceramic or hard, plastic resin. Most crowns made out of this type of material will begin to show wear rather quickly and are often only left in place a few months.
Permanent crowns, however, are meant to last several years. They’re normally made of dental grade porcelain, but gold or other metal alloys are also used.
