A dental crown is a way to fix a cavity that requires drilling. The crown is a tooth-shaped piece that is designed to fit over the tooth in order to fix the tooth’s size and shape. If the tooth is in bad shape, it helps the appearance of the tooth. Crowns need to be cemented into place, used in situations such as a weak tooth that is decaying. Dental Crowns are also necessary to restore a broken tooth that’s worn down. Sometimes there isn’t enough of a tooth left when a large filling is needed. Caps hold a dental bridge in place as well. Crowns can cover oddly shaped teeth or teeth that do not look white enough.
Dental crowns are often used cosmetically as well. There are teeth that get very damaged by decay and cannot withstand a filling. Permanent crowns can be made of metal or porcelain, or porcelain that is sealed together with metal. Metals used to make a crown can be made of metal alloys or two combinations of different metals such as nickel-chromium. Metal crowns can better withstand the chewing process. Porcelain fused to metal dental crowns can look like most normal, white teeth look.
Crowns made of all resin, are not as costly as other kinds of crowns. Temporary crowns can be made at the dental office while more elaborate ones need to be made in a lab. Getting a crown involves multiple visits to the dentist. X-rays are necessary to take because the measurements need to be exact. Root canals have to be prepared before the crown is placed, only because the tooth has to be drilled a certain way to make room for the crown. To measure the affected tooth, paste or putty is used for an impression. The dentist will have to choose the shade of the tooth that most fits the other teeth around it.
The dentist then removes the temporary crown, while putting in the permanent crown. It is best to avoid sticky foods during this time because the crown might come out. You have to minimize the use of your mouth in order to make sure that you chew on the unaffected side. You can’t chew hard foods like raw vegetables or pizza crust either. You have to slide not lift dental floss since dental floss can cause difficulty with your filling coming out. You have to use toothpaste for sensitive teeth and if you bite down, the crown is too high on the tooth.
Dental crowns can occasionally get loose also, causing discomfort. A chipped crown is another hazard and temporary fix. If the crown falls out, you need to clean the crown and the front of the tooth. Your dentist can re-cement the crown after this happens. Some people can have an allergic reaction to the metals or porcelain. A normal crown covers the whole tooth while onlays and ¾ dental crowns cover the underlying toothless than a full crown. A crown can last between 5 and 15 years, later on requiring a replacement.
