What are the types of Dental Crowns?
A dental crown is basically a cap for a weakened tooth. It can be fabricated from a variety of materials, including porcelain or metal. You could have a crown over a molar that rarely shows, or you may have a crown on a front tooth that was specifically designed to match your natural teeth. Once placed, a dental crown can strengthen the tooth, improving its overall functionality and appearance.
Why Would I Need a Crown?
You might require a crown for any number of reasons. If you have a large cavity that’s too big for a filling, it may be time for a crown.
You may also need a crown if your tooth is severely worn down, cracked or damaged and weakened. Dental crowns are also recommended after a root canal on a tooth because the tooth is fragile and needs protection.
You might be a candidate for a crown if you are missing a tooth, and your dentist needs to put in a dental bridge or an implant.
What Can I Expect When Getting a Crown?
Usually, two dental visits are needed to prepare a tooth for a dental crown to be placed. At the first visit the tooth is examined, x-rays taken, and the tooth is prepared by removing some enamel. An impression is made and sent to a dental lab for the fabrication of the crown. A temporary crown to protect the tooth is also placed.
In the second visit, after the crown is completed, the temporary crown will be removed, and the permanent custom-made crown fixed in place.
What Types of Crowns Are Available?
Permanent dental crowns can be made from a variety of different materials. Your dentist will advise you on which material, or combination of materials, will work best for you.
* Porcelain-fused-to-metal crowns- A porcelain-fused-to-metal dental crown is the most common option used. This type offers the best elements of both metal and porcelain. It will be stronger than a porcelain crown and it matches your natural teeth better than metal crowns. It can work well for front or back teeth.
* Metal or gold crowns- Metal and gold are the most durable material used for a dental crown. A metal crown can be made of different types of metal alloy, such as chromium and nickel-chromium. A gold crown is even more durable than metal-alloy. They both offer durability and can withstand the pressure from chewing, so they work great for molars. Metal and gold crowns are more noticeable since they are different than the natural shade of your teeth.
* Porcelain or ceramic crowns- A ceramic dental crown is the most appropriate for teeth at the front of the mouth since it can match the shade of your natural teeth. They are not as durable as metal or porcelain-fused-to-metal crowns, so they will not last as long if placed on back teeth used more for chewing.
Each type offers unique benefits, and the type that works best for you depends on your treatment goals and the position of the tooth that needs the dental crown.
