To produce dental crowns doctors usually use the certain kinds of dental crowns materials which are metal, porcelain-fused-to-metal, resin and pure porcelain, or ceramic. Metal crowns and porcelain crowns are the most firm and have the longest time of service. Metal crowns have a serious disadvantage which is their look. They do not look like natural teeth and their difference from normal teeth is very significant. So metal crowns are very good for the teeth which are out of sight but people do not usually use them for front teeth. Porcelain crowns are much better-looking and not less firm. Such dental crowns look like a natural tooth and their color may be selected to suit the colors of other teeth. In spite of their very high price, porcelain crowns are the most popular and the most frequently chosen by dentist patients.

Dental crown materials are produced and kept in special dental laboratories, where crowns are made on demand of dentists. Dentists in their dental rooms do not have materials to make a permanent crown, but they have all the necessary equipment and dental crown materials to produce and put a temporary crown, which is used to protect a damaged tooth for some time until the permanent crown is ready and delivered from the laboratory.

Crowns made of any dental crowns materials need simple care to serve for a longer time. Temporary crowns made of not so firm dental crowns materials need special care. Temporary crowns are usually used for two or three weeks. During this time you must try to avoid chewing food, such as chewing gums and other food of this kind. Try also not to eat hard food which is difficult to bite. It may break your temporary crown. It is better not to chew and bite in the part of mouth where a crowned tooth is located. Temporary crown is much more tender than the permanent one, so it must be treated very carefully.

Permanent crowns are less sensitive and do not need special treatment. To take care of permanent dental crowns normal dental hygiene is excellent: brush your teeth twice a day, avoid eating and drinking too hot and too cold food and drinks, and visit your dentist regularly.

In dependence of dental crown materials used in the crown different problems may occur with a crown. Dental crown of any material may cause certain discomfort, especially if gums are sensitive or nerve has remained in a tooth. This problem may disappear by itself after a while. If it doesn't, the crown is likely to be put incorrectly. Contact your dentist in order to eliminate discomfort.

Dental crown can also break or crack. It is the most frequent problem for porcelain and porcelain-fused-to-metal crowns. Metal crowns break or crack rarely, because they are made of firm metals, such as gold and nickel. If your crown has broken or cracked you obviously need a new one. If a crown falls off you have a chance to save it and put again. It will cost you less than a new crown.

All dental crowns materials are good enough to serve for a long time. However, the more expensive crown you choose the more chances you have to avoid problems with it for a while. Dental health care is not the field to save your money.
