Dental crowns are used for repairing damaged teeth and they may also be used to support bridges. Ideally, dental crowns may also act as a crown to restore dental implants. They are made of ceramics and take the shape of a tooth. The type of crown used depends on the dental condition being treated and this is usually determined by the dentist.
There are various types of dental crowns. The metal ones are less popular due to their aesthetic problems. They are externally visible and are not quite appealing. However, they are advantageous in terms of functionality and this is because of their durability; they have a long lasting life. Metals used to make dental crows are usually gold, palladium, chromium alloys and nickel.
On the other hand, ceramic dental crowns are made of porcelain, synthetic resins and some other ceramics. A huge advantage of ceramic crowns is that they look similar to the teeth and just like the enamel, they are also slightly translucent and have the same distinct natural gloss as teeth. In recent years use of ceramic crowns has outstripped metal ones.
Here is a YouTube video explaining dental crowns:
Dental crown procedures often involves 2 steps:
First, your dentist will remove the thin layers of enamel from your tooth to accommodate the tooth. An impression is then made and a crown is prepared in the dental lab. In the meantime, temporary crowns are inserted for some few days and once the crown is ready the temporary one is removed and replaced with a permanent one which gets cemented in place.
Dental crowns costs, vary from dentist to dentist, and they also depend on the quality of the material used. Porcelain and ceramic crowns are more expensive compared to the metal ones. The fee charged by the dentist and screening costs can also significantly affect the total amount you are to pay.
