What is a Crown?
- A crown, also known as cap,
is a dental restoration which covers and fits over the tooth and
restores it to its normal shape and size. A crown can make your
tooth stronger and also improve its appearance.
- there are a few types of crowns:
porcelain, porcelain fused to metal and all- metal.
When is a crown needed?
- A tooth is severely decayed and the
remaining tooth structure is weak
- After a tooth had root canal therapy
- A previously restored tooth which
had a large filling already and need to be replaced
- Fractures
- The tooth is used as support for a
bridge
- The above are only some of the
common indications for crowns
What does it involve?
- It usually takes at least two visits to complete a
crown.
- At the first appointment, the
tooth is prepared to receive the crown. An impression is taken and sent to a
dental laboratory where a dental technician will custom made the crown to
the shape and colour it needs. A temporary crown is fitted at the end of the
session.
- At the second appointment, the
temporary crown is removed and the final crown is adjusted and cemented onto
the tooth.
What is a bridge?
- A Bridge is a artificial tooth (pontic)
which is attached to a crown on each side. This is know as a fixed bridge
(as shown below).
- It is used to replace a missing tooth/teeth/space.
- There are also other types of bridges such
cantilever bridge (as shown by the pictures on the right) and Maryland bridge
