Crowns & Bridges

What is a dental crown?

A dental crown can be thought of as a cap covering your tooth to successfully restore its function, appearance, strength and ideal shape to its natural form.

A dental crown 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 improve the look, shape or colour of your tooth
  • Restore your ability to properly chew and speak by withstanding forces of mastication

All ceramic crowns

In recent years, porcelain crowns have been shown to have comparable strength and structural stability to that of metal crowns. These crowns have superb aesthetics and are most notably used for front teeth but have now become more common in the back molar teeth with the introduction of EMAX porcelain. Ask Dr. David chow what type of crown is best for you

What is a bridge?

A dental bridge is a dental restoration that ‘bridges a gap’ or a space of a missing tooth or teeth.  It is a fixed restoration because it is cemented into place and it is not removable. It is fabricated by preparing each tooth at either end of the gap for a crown (see What is a crown?) and having the laboratory construct the crowns at either end with the artificial tooth (called a pontic/pontics) in the middle.  Dr. David Chow can replace more than one tooth with a dental bridge.

When is a dental bridge necessary?

A bridge is generally recommended for those patients who either are going to lose a tooth or who have lost a tooth and do not desire to have a removable partial denture placed or wait for the healing time required for a dental implant. Dental bridges prevent the drifting of neighboring teeth, allowing you to chew and digest your food properly but they will not prevent the loss of jaw bone. If you would like a more natural, permanent restoration, consider dental implants. Crowns, bridges and dentures can all be supported by dental implants. Only dental implants can prevent bone loss which normally causes premature aging in most patients who do nothing about lost teeth.
