Dental crowns are tooth-shaped caps that are cemented onto the teeth to restore their shape, strength, size, and improve their appearance. They completely cover the visible portion of the tooth that lies at or above the gum line. Think of them as a "cap" or a "jacket" for your tooth. But what exactly are they for? Let's delve into the various reasons why dentists recommend crowns.
What are the different types of dental crowns?
There are several types of dental crowns, each with its own advantages and disadvantages. The dentist will recommend the best option based on your individual needs and preferences:
-
Porcelain crowns: These are highly aesthetic, closely matching the natural color of your teeth. They are strong and durable, making them ideal for visible teeth. However, they may not be as strong as other options for teeth that bear significant biting forces.
-
Ceramic crowns: Similar to porcelain crowns, ceramic crowns offer excellent aesthetics. They are highly biocompatible (meaning they are well-tolerated by the body) and are a popular choice for those with allergies to metal.
-
Metal crowns: These crowns, typically made from gold, alloys, or base metals, are highly durable and can withstand significant chewing forces. However, they are not as aesthetically pleasing as porcelain or ceramic crowns.
-
Porcelain-fused-to-metal (PFM) crowns: These combine the strength of a metal base with the aesthetic appeal of porcelain. This is a popular choice because it balances durability and appearance.
What problems do dental crowns solve?
Dental crowns address a variety of dental issues, improving both function and aesthetics. Here are some common reasons why a dentist might recommend a crown:
-
Protecting a weakened tooth: A tooth that has suffered significant damage from decay, cracks, or fractures can be strengthened and protected with a crown. The crown prevents further damage and maintains the tooth's integrity.
-
Restoring a broken or chipped tooth: Crowns can effectively repair severely chipped or broken teeth, restoring their shape and functionality.
-
Covering a discolored or misshapen tooth: If you have a tooth that is severely stained, discolored, or misshapen, a crown can completely cover these imperfections and improve the overall appearance of your smile.
-
Supporting a large filling: When a tooth has a very large filling, it can weaken the remaining tooth structure. A crown provides added support and prevents the tooth from fracturing.
-
Completing a root canal: After a root canal, the tooth can become brittle. A crown protects the weakened tooth from further damage and maintains its strength and function.
-
Improving the appearance of a dental implant: Crowns are used to cap dental implants, providing a natural-looking and functional replacement for a missing tooth.
-
Covering a tooth after an injury: Teeth damaged by trauma may need to be restored with a crown.
How long do dental crowns last?
With proper care, dental crowns can last for many years, even decades. However, the lifespan of a crown can vary depending on several factors including the type of crown, the oral hygiene practices of the patient, and the amount of biting force placed on the tooth. Regular dental checkups and good oral hygiene are crucial for maintaining the longevity of your crowns.
What is the procedure for getting a dental crown?
The process typically involves two appointments. The first visit focuses on preparing the tooth by removing a layer of enamel, taking impressions, and possibly placing a temporary crown. The second appointment involves fitting and cementing the permanent crown.
How much do dental crowns cost?
The cost of a dental crown varies greatly depending on the material used, the location of the dental practice, and other factors. It's advisable to discuss the cost with your dentist before proceeding with the treatment.
How do I take care of a dental crown?
Maintaining good oral hygiene is essential for the longevity of your dental crown. This involves brushing and flossing twice daily, using fluoride toothpaste, and visiting your dentist for regular checkups and cleanings. Avoid chewing on hard objects, as this can damage your crown.
