Dental Crowns

Dental Crown

Dental Crowns can:

 

  • Cover a tooth with a large filling that is unsupported by the amount of tooth structure remaining
  • Restore teeth that have cracks or fractures in them and/or the filling material
  • Restore a tooth that has undergone endodontic treatment (root canal)
  • Restore your smile and improving the cosmetics in arrangement, shape or color
  • Restore your ability to properly chew and speak by withstanding forces of mastication

 

Types of dental crowns

1) All Ceramic Crowns

In recent years, porcelain crown’s have been shown to have comparable strength and structural stability to that of metal crowns. These crown have superb aesthetics and are most notably used for front teeth .

2) Porcelain Fused To Metal Crowns

This crown looks like a natural tooth (porcelain) from the outside with a thin invisible metal layer underneath to provide added strength for patients who have grinding and clenching habits. Sometimes the metal underlying the crown can show through as a dark line usually at the gum line. They are mostly used on molar teeth.
3) Full Metal Crown (FMC)

Full metal crown’s are a gold-palladium alloy with a mixture of other metals. This type of crown is notably utilized for teeth that have limited tooth structure for retention. FMC crowns are found in the back teeth where aesthetics are not a concern.

How is a dental crown accomplished?

You will be given a mild anesthetic to numb the area, and then the dentist will remove/reduce the enamel to accommodate the thickness of the crown. When the tooth already have fillings, part of the filling may be left in place to help as a foundation for the crown. The dentist will then take an impression either digitally or with impression material, which will serve as the model from which the crown will be made. Digital impressions are taken for All Ceramic Crowns using Cerec technology to fabricate crowns in one appointment. Impression paste will be used for crowns (PFM or FMC) that require a dental laboratory to fabricate your crown. A temporary crown will be placed for you to wear while your crown is being made until your next visit. This temporary crown will serve to protect your teeth and gums. On your second appointment, the temporary crown will be removed. Your new permanent crown will be fitted and checked and adjusted for any bite discrepancies. Your new crown will then be cemented permanently to your teeth.
