Questions About Dental Crowns

Uncategorized

A dental crown is an artificial tooth that is fabricated to be fitted over your existing tooth after it has been trimmed and shaped. It covers the visible portion of the tooth down to the gum line and restores the shape, size, color, and function of your tooth. 

With proper care and maintenance, crowns can last 15-20 years. The PFM crown is fabricated with very durable material that has superior strength and load-bearing capacity and can last a long time. 

Why would I need a dental crown?

A dental crown can be given by your dentist for several reasons, such as:

  • Protecting a fragile tooth 
  • Restoring a severely worn-down tooth
  • Loss of significant tooth structure where a simple filling won’t last long enough
  • To improve the shape, size, or color of natural tooth
  • Covering a dental implant.
  • Covering a root canal-treated tooth
  • To repair a fractured or cracked tooth.

Caring for a new dental crown

Care for a dental crown just like you would for a natural tooth. Maintain good oral hygiene and don’t forget to visit your dentist every six months for a routine checkup and cleaning. 

Do I need some downtime after my crown placement appointment?

There is no downtime required after your crown is placed. It is a non-surgical treatment and there is no serious pain or discomfort and one can continue with their day-to-day routine immediately.

Onlays and 3/4 crowns

Onlays and 3/4 crowns are more conservative crowns that don’t cover as much of your underlying tooth as traditional dental crowns. They are a more conservative approach that might be appropriate when there is still a significant solid tooth structure present. It’s considered compared to full coverage of your crown. What are dental crowns made of?

Dental crowns can be fabricated out of different materials, such as 

Metal: Several metals can be used in dental crowns, They rarely chip or break, require a small amount of tooth structure to be removed, and are durable and long-lasting. The only drawback is the metallic color, making them a good choice for molars.

What will happen at my dental crown appointment?

During the first visit, your dentist will evaluate the tooth and its surrounding structures. Once it’s decided to be crowned, the tooth will be reduced a small amount, to make space for the crown itself. After preparing, an impression of the tooth is taken which is then sent to a dental laboratory. Meanwhile, your dentist will make a temporary crown to cover and protect the prepared tooth till the permanent crown is made.
