A dental crown or “cap” is a non-removable shell that covers the entire outer surface of a tooth. Crowns can be made of tooth-coloured porcelain or gold and are utilized to reinforce teeth or to improve their appearance. Patients have crowns placed to strengthen teeth compromised by:
- Cracks or fractures
- Large fillings
- Large or deep cavities
- Previous root canal therapy
A crown prevents future damage to a tooth and limits the growth or extension of cracks through the tooth. Root canal treatment leaves a tooth more brittle and susceptible to fracture and so a crown prevents unrestorable cracking and tooth loss.
A dental crown may also be placed for esthetic reasons to improve the appearance of teeth that are:
- Misshapen or mispositioned
- Stained severely
- Discoloured following root canal treatment
Crowns provide a smooth and uniform tooth-coloured surface to correct the colour and shape defects that are present. They can be designed to match the exact colour of neighboring teeth. Your crown will be made to have a shape that fits your smile perfectly.
What is involved in having my crown made?
First, your tooth is prepared by removing any decayed or weakened portions. During this preparation, your tooth is shaped so that the crown can fit properly. We then take a highly accurate impression to capture the shape of the prepared tooth. Next, we place a temporary crown on your tooth to protect it until your second appointment. At your second appointment, the temporary crown is removed, and the permanent crown is seated for a “try-in”. The try-in allows me to ensure that:
- Your bite is comfortable
- Your new crown is sealed properly to your tooth
- You approve of both the shape and colour or “shade” of the crown
Once we are satisfied with the crown and you approve the colour and shape, we can bond the crown to the tooth. You will be instructed to avoid heavy chewing on the new crown for 72 hours. You will also be advised to avoid flossing around the crown for 72 hours.
If you have broken or cracked a tooth or are experiencing sharp biting pain, you may benefit from the placement of a dental crown. Please contact us to book a free consult appointment with Dr. Kyle Hornby.
