A dental crown is a type of dental restoration which completely covers a tooth. A dental crown is often used to protect a tooth that has been weakened from decay, or after a root canal. Dental crowns are also used to cover dental implants, to keep a dental bridge in place, and to cover discolored or misshapen teeth. Dental crowns are held into place with a dental cement. These crowns need to be custom made to fit the exact shape and size of the tooth.
A dentist must start preparing your tooth for the crown cautiously. The dentist usually takes x-rays on the tooth, and carries out a root canal if required. This particular root canal might help prevent an infection in the tooth’s pulp. The dentist then files down the tooth, to create place for the crown. Any important areas of your tooth missing should be built-up, or filled up, like a hole. The dentist then simply makes an impression of your tooth, with a dental impression composite. The dentist typically creates a temporary crown in his/her clinic that you should use, and a model of the tooth is delivered to an outside lab to produce the final product. The production of the final crown normally takes about three weeks.
Dental crowns are made from many different materials. Metal crowns are very affordable, but are normally only used for the very back molars, since not many people find metallic looking teeth attractive. All-resin crowns are also available, but wear down quickly and are more prone to breakage than other types of crowns. All-porcelain crowns offer one of the best color matches to the natural tooth, however, they are prone to wearing down the opposing tooth, and are also not very strong. This type of crown is best suitable when a crown for a front tooth is needed. Porcelain-fused-to-metal crowns are deemed as the best overall dental crown to use. They are literally a metal crown covered in porcelain. This gives you the strength of the metal crown and the tooth-matching color of the porcelain crown. The porcelain on these crowns can chip, exposing the metal underneath, so there is no true perfect crown out there.
These kinds of crowns may range in cost depending on the content it is made of, amongst other things, including the fees the dentist charges for his professional expertise in preparing your tooth and setting up the shape of the dental crown. Prices do range from as low as $500, up to $3,000 a tooth. The porcelain-fused-to-metal variety can be one of the most affordable. All-porcelain and all-resin varieties are normally the most expensive, because of the bigger ability associated with making, and color-matching them.
