A dental crown refers to a type of dental cap, which completely
covers, or surround a tooth or a dental implant and is generally bonded
with the tooth with the help of dental cement. The crowns are generally
used for improving the strength as well as appearance of the teeth.
The traditional and the most common procedure for crowning involve taking an impression of a prepared tooth for fabricating the crown outside the mouth. Thereafter, the crown could be inserted at the subsequent point and restored with the help of dental cement.
Dental crowns are available in various varieties and made from various materials; and you can select the one, which best suits your requirement in accordance with the recommendation of your dentist. The following are some of the most popular types of dental crowns, which are available in the market:
1. Metal Crowns
Metal crowns may not have a very aesthetic appearance, but definitely they are more durable than most other types of crowns. Due this reason, they are not very much recommended for teeth, which are highly visible, such as incisors or canines, but are an ideal choice, as far as back teeth like molars are concerned. Metal crowns are made of gold alloy, nickel alloy, palladium, or chromium alloy.
2. All Ceramic Crowns
The all ceramic crowns are made of porcelain, resins, as well as dental ceramic materials. These crowns have a natural appearance and hence are typically used for front teeth. The ceramic material is translucent in appearance, just like teeth enamel and can be carefully matched with the adjoining teeth. However, they are not as durable as metal crowns and therefore are not recommended for back teeth.
3. Porcelain Crowns
Porcelain fused to metal crowns are more durable than the all-ceramic crowns and at the same time, carry a natural look as well. However they tend to wear over time and a thin metal band gets revealed alongside the gum line.
As it is, whatever type of crown you choose, it is always better to go by the recommendation of your dentist.
