Crowns

Just because some of your teeth may have suffered damage doesn’t mean they can’t be made to look beautiful once again. A dental crown is a tooth-shaped “cap” that is placed over a damaged tooth to restore its shape, size, strength and appearance.

 

Once cemented in place, the crown will fully encase the entire visible portion of a tooth. They can be either temporary or permanent. Temporary crowns can be made right in your doctor’s office, whereas permanent crowns are made in a laboratory.

 

On average, dental crowns last between 5 and 15 years, depending on the material used and the level of precaution taken by the patient.

Frequently

Asked

Questions

When is a Dental Crown Needed?

A dental crown may be needed to:

– Protect a weak tooth from breaking

– Hold together parts of a cracked tooth

– Cover and support a tooth with a large filling

– Hold a dental bridge in place

– Cover misshaped or severely discolored teeth

– Cover a dental implant

How Does the Procedure Work?

The crowning process typically requires two visits:

 

First Visit

 

During the first visit, your dentist may take X-rays to ensure the health of the root and bone associated with the affected tooth. The dentist will administer a local anesthetic before filing down the surfaces of the tooth. The amount removed depends on the type of crown used. If a large area of the tooth is missing due to decay or damage, your dentist will use filling material to build up the tooth to support the crown.

 

A mold is then taken of the tooth and the teeth above or below it. The impressions are sent to a dental laboratory where the crown will be manufactured and sent to your dentist in two to three weeks. If your crown is made of porcelain, your dentist will select the most appropriate shade. During the first office visit, your dentist will make a temporary crown to cover and protect the prepared tooth while the crown is being made.

 

Between your visits, you need to ensure you take care of the temporary crown. The doctor will go over this with you. Some precautions to follow include:

–  avoiding sticky, chewy or hard foods

– minimizing use of the side of your mouth with the temporary crown

 

Second Visit

 

At your next visit, we remove your temporary crown and permanently cement the final crown in place. Sensitivity and discomfort are not uncommon after the procedure. Increased sensitivity to heat and cold may also occur of there is a nerve in the affected tooth.

What are Dental Crowns Made of?

Permanent crowns can be made from metal, resin, ceramics or a combination of metal and ceramic.

 

– Metals used in crowns include gold alloy, other alloys such as palladium or a base-metal alloy like nickel or chromium. Compared with other crown types, metal crowns require the removal of less tooth structure. They withstand biting and chewing and take longer to wear down that other crown materials. The metallic color is the main drawback for patients. This makes metal crowns a great choice for out-of-sight molars.

– All-resin dental crowns are less expensive than other crown types, but they wear down quicker and are more prone to fractures.

– All-ceramic or all-porcelain dental crowns provide the best natural color match and are more suitable for people with metal allergies. However, they may wear down opposing teeth more than metal or resin crowns and are prone to chipping. Minor chips can be repaired, but serious ones may require replacement. All-ceramic crowns are a good choice for front teeth.

– Unlike metal crowns, porcelain-fused-to-metal dental crowns can be color-matched to your adjacent teeth. However, more wear occurs to the opposing teeth compared to other crown materials, and the porcelain portion can chip. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth, though the metal may show through the porcelain.
