CROWNs

dental crown is a tooth-shaped "cap" that is placed over a tooth -- to cover the tooth to restore its shape and size, strength, and improve its appearance.

 

The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.

 

Why Is a Dental Crown Needed?

 

dental crown may be needed in the following situations:

 

  • To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth

  • To restore an already broken tooth or a tooth that has been severely worn down

  • To cover and support a tooth with a large filling when there isn't a lot of tooth left

  • To hold a dental bridge in place

  • To cover misshapened or severely discolored teeth

  • To cover a dental implant

  • To make a cosmetic modification

  • Save a tooth that has been so damaged by decay that it can't support a filling.

  • Protect the teeth of a child at high risk for tooth decay, especially when a child has difficulty keeping up with daily oral hygiene.

  • Decrease the frequency of general anesthesia for children unable because of age, behavior, or medical history to fully cooperate with the requirements of proper dental care.

  • In such cases, a pediatric dentist is likely to recommend a stainless steel crown.What

 

What Steps Are Involved in Preparing a Tooth for a Crown?

 

Preparing a tooth for a crown usually requires two visits to the dentist -- the first step involves examining and preparing the tooth, the second visit involves placement of the permanent crown.

 

First visit: Examining and preparing the tooth

 

At the first visit in preparation for a crown, your dentist may take a few X-rays to check the roots of the tooth receiving the crown and surrounding bone. If the tooth has extensive decay or if there is a risk of infection or injury to the tooth's pulp, a root canal treatment may first be performed.

 

Before the process of making a crown begins, your dentist will anesthetize (numb) the tooth and the gum tissue around the tooth. Next, the tooth receiving the crown is filed down along the chewing surface and sides to make room for the crown. The amount removed depends on the type of crown used. If, on the other hand, 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.

After reshaping the tooth, your dentist typically will use a paste or putty to make an impression of the tooth to receive the crown. Impressions are made with a digital scanner. Impressions of the teeth above and below the tooth to receive the dental crown will also be made to make sure that the crown will not affect your bite.

 

The impressions or scans are sent to a dental lab where the crown will be manufactured. The crown is usually returned to your dentist's office in two to three weeks. Dr. Rez only does full porcelain and or Zirconia crowns as these materials are durable and aesthetically pleasing. A shade that most closely matches the color of the neighboring teeth will be selected. During this first office visit your dentist will make a temporary crown to cover and protect the prepared tooth while the crown is being fabricated. Temporary crowns usually are made of acrylic and are held in place using a temporary cement.

 

Second visit: Receiving the permanent dental crown

 

At the second visit, your temporary crown is removed and if everything is acceptable, a local anesthetic will be used to numb the tooth and the new crown is permanently cemented in place.
