What are Dental Crowns / Caps?
A dental crown restores a tooth’s shape, size, and strength. It fully encases the visible portion of your tooth or dental implant. Once it is permanently bonded in place, only a Dentist or Specialist can remove it. With proper care and good oral hygiene, the life of a crown can range from 5 to 15 years.
When would I need a crown?
A crown may be prescribed by your dentist to:
- Restore and protect a tooth that is worn, decayed, cracked, or broken
- Protect and support a tooth after a very large filling or root canal treatment
- Cover a dental implant
- Hold a dental bridge or other prosthetic device in place
- Improve your smile by covering a misshapen or severely discoloured tooth
What to expect during Crown procedure:
Crown procedures usually require 2 visits to the dentist. At the first visit, Abbotsford Dental will prepare your tooth for the crown. In order to do so, your dentist will numb your tooth and surrounding tissues with a local anaesthetic. Then, the dentist will trim the surface of the tooth to make room for the crown. Once the tooth is the correct size and shape, your dentist will make impressions of your tooth and will send those impressions to a dental lab. The lab technicians will create a crown that is perfect for your smile. While you wait, you will be given a temporary crown.
When your new crown is done, you will come back to our office to get it placed. Your dentist will first check the fit and appearance of the crown and if it exceeds expectations, the dentist will permanently cement it into place.
What are the different types of crowns?
Abbotsford Dental will recommend the best type of crown for your dental restoration needs based on the chewing placement and structure of the tooth or implant that requires protection. There are three types of crowns. Each type has its own characteristics and qualities:
- Full Porcelain: Porcelain is attractive, strong, stable, and highly resistant to wear. It offers a high level of biocompatibility because it does not contain metal.A porcelain crown provides the best natural colour match to the rest of your teeth and is an excellent choice for front teeth.
- Full-Metal: Metal offers strength and endurance. A metal crown may be recommended for back teeth where the forces of biting and chewing are the greatest. A metal crown rarely chips or breaks. In addition, it requires minimal removal of tooth structure.A gold or other high-noble metal crown offers biocompatibility. A base metal crown is often the least expensive treatment options; however, it lacks biocompatibility and may cause allergic reactions or gumline discolouration.
- Porcelain-Fused-to-Metal: Porcelain-fused-to-metal offers the benefits of a natural surface colour that resembles the rest of your teeth and the strength of a metal substructure.While there are several advantages to selecting this type of crown, it requires the removal of more tooth structure than other types of crowns. This means that there is greater potential for patient discomfort during the treatment procedure.
