What are dental crowns?
Dental crowns or teeth crowns are one of the commonly advised dental procedures for severely decayed teeth. Commonly known as a cap, the crown is a tooth-shaped cover, which is placed over the damaged tooth. The procedure is referred to as dental crown procedure.
Why is it necessary?
The teeth are an essential part of our digestive system, which helps grind the food we eat. Teeth decay affects the strength of the teeth, and necessitates procedures such as fillings or teeth crowns, to strengthen the affected teeth.
What are the types of crowns?
Teeth caps are available in different forms and are generally formed in the dental lab, according to the tooth shape and size. These are made from different materials such as metals (gold, nickel, or chromium), resins and porcelain (often referred to as ceramic dental crowns). While metallic ones require lesser tooth trimming for the crown placement, they may not be suitable for the front teeth because of their metallic appearance. Porcelain ones on the other hand, can be matched to your teeth color, and are hence preferred over the metal caps.
What is tooth trimming?
Talking about tooth trimming, it is one of the most essential steps of the dental crown procedure. This involves reducing the width and height of the tooth that is selected to receive the dental cap.
What is the procedure?
During the crown procedure, the dentist trims your teeth using a drill. This may be done under local anesthesia, if you feel any pain or sensitivity during the procedure. The next part of the procedure is taking an impression of the trimmed tooth. A cast or a plaster model of the impression is then prepared and sent to the lab for forming the teeth cap. Once ready, the dentist fixes it with a special cement to ensure that it remains fixed.
How many days does it take?
Dental crown procedures often require 2 to 5 sittings, based on the amount of tooth destruction.
How much does it cost?
The cost of teeth crowns are mainly based on the type of the material and the number of units required. The cost may also vary in different regions.
How long does it last?
Once placed, the dental crowns may last for six months to 15 years based on the type of material used. Along with restoring the affected teeth, they can also be used to replace missing teeth. These are then referred to as a bridge.
The dental crowns have thereby become an essential part of the teeth saving procedures commonly followed by dentists all over the world.
