Porcelain Crowns

Protect and Strengthen individual teeth for a stronger bite.

A crown or a "cap" is placed on an individual tooth to restore its shape, size, strength, and/or to improve its appearance. When bonded into place, a crown fully encases the entire visible portion of a tooth. Crowns can be made from different materials including porcelain, zirconia, gold or a combination thereof. The majority of the crowns placed at Dentistry at Vitality Health are all-porcelain (metal-free).

Why Is a Dental Crown Needed?

A 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 one that has been severely worn down
  • To cover and support a tooth with a large filling when there is little tooth structure remaining
  • To hold a dental bridge in place
  • To cover misshaped or severely discoloured teeth
  • To restore the tooth portion of a dental implant
  • To protect and strengthn a root canal treated tooth

What steps are involved in preparing a tooth for a crown?

We offer both CEREC in-office crowns as well as lab-fabricated crowns. Lab fabricated crowns usually require two visits to our office. The first visit involves examining and preparing the tooth, while the second visit involves placement of the permanent crown. 

CEREC AC Crowns are made and placed in a single appointment! This is possible through the use of a state-of-the-art digital CAD-CAM, milling system that allows scanning, design & manufacture of your crown all in the same appointment.

A Lab-fabricated crown is sometimes your best solution in certain circumstances.

At the first visit, Dr. Singh will first anaesthetize (numb) your tooth and the gum tissue around the tooth. Next, the tooth receiving the crown is shaped to accommodate the crown.

After reshaping the tooth, a restorative hygienist will use a special material to take an accurate impression of the tooth. A temporary crown is then places on the tooth.

The impressions are sent to our dental laboratory for fabrication of the crown. The crown is usually returned to our office in 10-14 days.

At your second visit, Dr. Singh will remove your temporary crown and check the fit and colour of the permanent crown. Once we verify that everything fits ideally, the new crown is permanently bonded in place.

What are CEREC porcelain restorations?

The CEREC CAD-CAM system can be used to make porcelain inlays, onlays and crowns in a single visit. They are the most aesthetic and compatible substitute for natural enamel. The porcelain is tooth coloured, non- metallic & contains no mercury. CEREC restorations have significantly less post-operative sensitivity and are much more resistant to wear as compared to composite resins.

CEREC porcelain restorations wear at about the same rate as natural tooth structure, are biocompatible, bonded to tooth structure and provide a perfect seal between the tooth and the restoration thereby minimizing the chance of recurrent decay. The bonding process also enhances the structural integrity of the tooth by strengthening the tooth, therefore making it less likely to fracture, chip or break under normal chewing forces. 

How is a CEREC porcelain restoration made? 

CEREC restorations only require one appointment. The procedure begins with local anesthetic and the placement of a rubber shield (rubber dam) around the tooth. Once the tooth is prepared, a thin layer of non-reflective powder is applied to the prepared surface. Using a special camera, a scan of the preparation is then taken and an "optical impression" of the tooth is created by the software. The CEREC machine works off this scan to design the restoration.  The porcelain is then milled to very exacting dimensions. Once complete, the porcelain restoration is bonded to the tooth and polished. The bite is adjusted as necessary and the procedure is complete.

NOTE: The traditional “goopy” impressions are completely eliminated!  An added benefit for those patients that have a strong gag reflex.

How long do dental crowns last? 

Crowns are a long-term, long-lasting restorative solution. The life span of a crown depends on the amount of "wear and tear" the crown is exposed to, how well you follow good oral hygiene practices, and your personal mouth-related habits (you should avoid such habits as grinding or clenching your teeth, chewing ice, biting your fingernails and using your teeth to open packaging).

Does a crowned tooth require any special care?

While a crowned tooth does not require any special care, remember that simply because a tooth is crowned does not mean that the root is not vulnerable to decay or gum disease. Therefore, continue to follow good oral hygiene practices, including brushing your teeth at least twice a day and flossing at least once a day and maintaining your prescribed professional cleanings.
