What You Need to Know About Dental Crowns

Posted on: April 9th, 2014 by Sam Khammar
Dental CrownsIt is important when considering dental crowns to understand what exactly it is and why it is important. Fundamentally a tooth can be divided into two parts, equally important. The first is the root, which is covered by the gum and bone in the case of a healthy individual. The second part is known as the crown and is the part of the tooth that is visible in the mouth above the gum line on the lower teeth and below the gum line on the upper teeth. Essentially what laymen know as teeth are in fact the “clinical crown”. Anytime repairs are done to restore a partial part of this clinical crown or a cover is fitted to complete cover it, that cover is known as a dental crown. Dental crowns are often used to protect a tooth (one weakened by decay for example) from becoming cracked, chipped, or damaged further. Sometimes dental crowns simply hold pieces of a broken tooth together. In other cases the dental crown is used to restore an already broken tooth that has been severely worn down or to cover and support a filing when there is not enough natural tooth left. In children the dental crown may be used to protect the teeth of a child who has shown the be susceptible to a high level of decay or one that has a hard time keeping up with brushing, flossing, and other important aspects of oral hygiene. Crowns are also used to cover severely stained teeth and have a cosmetic application when they are used for cosmetic modification. A crown is one of the most versatile tools a dentist has at his disposal due to the fact that they have so many uses and come in a variety of materials. Stainless steel crowns are prefabricated crowns that are used, only on permanent teeth, as a temporary measure to protect a tooth or a filling while a permanent crown is made from another material. In pediatric dentistry, the stainless steel crown is used primarily as a temporary measure to make room for a permanent tooth. Gold teeth, once all the rage in some fashion circles, are an example of metals being used to make crowns. Other crown making materials include Porcelain fused to metal, which are long lasting but have the effect of wearing down other teeth that they come in contact with, All resin crowns which are a cheaper version of crowns but tend to break or fracture more easily, and All ceramic or All porcelain crowns which provide the best cosmetic value since they can be easily matched to existing tooth color. Getting a crown fitted can often be a long process, involving multiple trips to the dentist. Since a dental crown has to be fitted specific to, not just the individual, but the individual tooth the dentist will spend the first visit taking x-rays, filing down the tooth’s chewing surface to make room for the crown, and taking an impression of the space that requires the crown using putty or paste. This mold is then used by a dental laboratory to manufacture the exact dental crown requested by your dentist, including the shade, if you are getting a porcelain crown. Dental crowns allow dentists to do miracle work in tooth restoration and have strong application both in protecting the teeth and in replacing them when necessary.
