What are crowns and bridges?
Bridges and crowns are both fixed prosthetics that are cemented onto existing teeth or implants by a dentist. Crowns are used to cover damaged teeth. Bridges are false teeth that are held in place by the abutment teeth on either side of the gap.
When do I need a crown?
You can benefit from a crown when you have:
- A tooth that is fractured or damaged
- Decay that has weakened a tooth
- A tooth that is severely discoloured
- A misshapen tooth
- A dental bridge that needs an anchor
When do I need a bridge?
You may benefit from one or more bridges if you have a missing tooth or teeth that need to be replaced. It is also a suitable option for patients who find dentures too uncomfortable, unstable or aesthetically displeasing.
Procedure for inserting crowns
Firstly, your dentist will apply anaesthetic to numb the tooth, getting the crown and the surrounding gum tissue. We then use a dental drill and an abrasive bur to remove the outer surface of the tooth, creating enough room for the crown to be placed. Next, we make an impression of the tooth, which is sent to a dental laboratory that will manufacture the crown. A temporary crown is placed, while we wait for the permanent crown from the laboratory.
At your second appointment, we remove the temporary crown and insert the permanent one. The new crown is adjusted to properly fit your tooth and bite. We use a special cement to attach the crown to the tooth. When the cement sets, the crown is firmly attached to the tooth.
Although crowns and bridges may last a lifetime, they do sometimes come fall out or come loose. Practising good oral hygiene will help ensure the longevity of your crowns and bridges. Also, visit your dentist regularly for check-ups and cleanings. Avoid chewing hard foods, ice or other hard objects to prevent damage to your new crown or bridge,
