At Ottawa Dentistry, our dentists use porcelain dental crowns to help restore and protect damaged teeth.
What is a Dental Crown?
A dental crown is hollow, artificial tooth that your dentist places over an entire damaged tooth to restore and protect it. It reconstructs a tooth to its original size and shape, restoring your smile.
At Ottawa Dentistry, we use porcelain dental crowns which can be easily matched to the shape, size and colour of your natural teeth.
Porcelain crowns are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced.
Reasons for Crowns
Dental crowns fully cover the entire visible part of a tooth. If your tooth is damaged, a filling with tooth-colored composite material is often not strong enough to withstand your chewing force. In these cases, a crown is highly indicated. There are a number of situations in which your dentist may use one, including:
- To protect weak teeth from breaking
- To hold together and restore an already broken tooth
- To cover a tooth after a root canal
- To cover crooked or discoloured teeth
One Visit Crown Ceramic Restorations
Traditionally, restorations like crowns require at least two visits. In the first visit, after the tooth is prepared for a ceramic restoration, multiple impressions are taken and then sent to a laboratory for fabrication. In the second visit, the restoration is then cemented to your tooth. Usually, local anesthetic injections are done in both visits.
With today's CAD/CAM technology, we at Ottawa Dentistry can fabricate your ceramic restoration right in our office. An optical impression of the prepared tooth is taken then send wirelessly to our milling unit and a crown is milled from a manufactured ceramic block. It is then glazed and cemented to your tooth.
The quality of the CAD/CAM ceramic restoration is parallel to the laboratory fabricated one. There are numerous advantages in this technique. Some of them include: local anesthetic only being applied once and only if needed, and there being no temporary acrylic crown required between your two visits.
