Installing dental crowns is one of the most common dental procedures a dentist performs on a daily basis. A fair question asked by many patients is whether they really need a crown. Here are some facts about dental crowns and what patients need to know before they walk into a dentist’s appointment.
What is a Dental Crown?
A dental crown, also known as a dental cap, is a fixed prosthetic object which is cemented onto a tooth for dental restoration. It is like a hat which covers all or part of a tooth that is above the gum line. A crown is only removed and fitted by a dentist. Its lifespan is 7-15 years with regular dental checkups and proper oral hygiene.
In preparation for fitting the crown on the tooth, the dentist numbs the area around that particular tooth and removes about 1-3 millimeters of the tooth from the back, front, sides, and the biting surface. As a result, a ‘mini-tooth’ is created, leaving space for the crown to be placed. Often, a temporary crown is placed on the impression before the dentist fabricates your crown.
Once the dentist completes making your crown, an appointment is scheduled to have it fixed. Upon installation, the crown is checked thoroughly and is cemented on the tooth.
What are Dental Crowns For?
Dental crowns are mainly recommended for teeth at risk of fracture such as those with large fillings or showing fracture lines. They cover damaged teeth to strengthen and improve the overall appearance and alignment of the teeth.
Types of Dental Crowns
There are several types of dental crowns. They include:
- Ceramic Crowns
This crown is mainly used for restoring front teeth as they blend with the natural tooth color. It is made up of porcelain-based material.
- Porcelain-Fused to Metal Crowns
This crown provides a stronger bond as compared to regular porcelain crowns, due to its connection to a metal structure. It is extremely durable as well as aesthetically pleasing.
- Gold Alloy Crowns
These crowns are very strong and reliable as they are made of a mix of gold, copper, and other metals. It does not fracture nor does it wear away the tooth itself.
- Base Metal Alloy Crowns
These crowns are made of non-noble metals which are highly resistant to corrosion and make a strong crown; hence very durable. This crown requires the least amount of healthy tooth to be removed prior to fitting.
When is it Necessary to Have a Dental Crown?
Different people have different reasons for getting dental crowns. Some of them include:
- Fixing esthetically crooked teeth.
- Covering stained teeth both in front and inside your mouth.
- To protect a weakened tooth.
- To strengthen a tooth which has undergone numerous dental procedures such as root canals; hence making it weak.
