What Are Dental Crowns and Onlays?
A dental crown is a tooth-shaped cap which gets placed over a damaged or decayed tooth. Crowns are designed to emulate the tooth’s shape, size, strength, and appearance, effectively protecting it from further damage. Onlays are a more conservative crown that can be used when less tooth structure is missing. Onlays are usually used on back teeth, while crowns can be used on front and back teeth.
When Are Crowns Recommended?
- To cover and strengthen a tooth that has been weakened by decay over time or a root canal.
- To restore a tooth that has been chipped, cracked, or worn down.
- To cover and support a tooth with a larger filling when there isn’t enough natural tooth structure left.
- To improve the appearance of a discoloured or misshapen tooth.
The Process:
- Dr. Macdonnell will prepare the tooth by removing any damaged or decayed areas.
- A temporary crown is placed to protect the tooth while your custom porcelain crown is being made.
- Once ready, the permanent crown is carefully fitted and bonded to your tooth for a secure, natural-looking result.
What Are Dental Bridges?
A dental bridge is often used to replace one or more missing teeth at once. It is made of one or more artificial teeth (called pontics) held in place by crowns that are attached to the remaining natural teeth on either side of the gap. Bridges restore your smile, maintain the proper alignment of your remaining teeth and prevent them from shifting.
When Are Bridges Recommended?
- To replace one or more missing teeth.
- To prevent other teeth from shifting into an empty space from a missing tooth or teeth, which can lead to bite issues.
- To restore your ability to comfortably chew and speak.
The Process:
- The natural teeth on either side of the gap are prepared for crowns.
- An impression is taken to create a custom bridge that matches your bite and natural teeth.
- The bridge is placed and adjusted for a perfect fit.
