A crown is a dental cap that is put on a damaged tooth to help restoring its size, shape and strength, covering the entire visible part of the tooth.
There are many reasons for getting a dental crown:
- It restores a tooth that is already broken or worn out;
- Helps to shield a tooth from decay or cracking;
- It helps to anchor a dental bridge;
- It hides discolored or misplaced teeth;
- It hides dental implants;
- It acts as a protective cap in case the tooth had a root canal treatment.
Types of Crowns and their Specifications:
Lab-made dental crowns can be made of just metal, metal fused to porcelain, lithium disilicate, porcelain fused to zirconia or just zirconia.
Sometimes several metal alloys like gold and palladium or nickel-chromium alloy are used, being quite resistant and long lasting. Their only drawback is the metallic color. This is why they are mainly used for molars and pre-molars by most dentists.
Porcelain fused to metal crowns can be made to match specific tooth shades. Compared to metallic crowns, porcelain ones wear away faster than full metal crowns. Sometimes a dark patch of metal can be seen through the porcelain when it wears away. This occurs mainly on the biting surface.
Lithium disilicate crowns, also known as Emax crowns, have a beautiful translucency to them that resembles teeth better than any other material. It is stronger than porcelain but weaker than metal.
The strongest types of crowns are the full zirconia crowns. They are especially recommended for grinders because they are almost unbreakable. They are more opaque looking than Emax crowns but still match teeth very well and are metal-free.
Temporary Dental Crowns:
Temporary crowns can be easily created at a dentist’s office. They are either made of stainless steel or acrylic and are mainly used for restoration purposes, until the actual crown or permanent crown is ready. Temporary crowns are very delicate and need additional care. It’s suggested to avoid eating sticky or hard foods when wearing a temporary crown because these foods may dislocate or break it.
Cost of Dental Crowns:
The cost of a dental crown depends mainly on the type of material selected for crowning and it can vary from $800 to $2,500 in the US.
