Bridges
Dental Bridges are false teeth that are anchored to one or two neighbouring teeth to ‘bridge’ a gap.
There are different types of bridges.
Conventional Fixed Bridges
This involves preparing the adjacent teeth so they can accept crowns or ‘caps’ which are made so they have an additional crown fixed to them to replace missing teeth. These are then cemented or bonded into place.
The advantages are:
1) They are fixed permanently in place unlike a denture.
2) They are stronger and more durable than adhesive bridges.
The disadvantages are:
1) They involve drilling and preparing one or two of the neighbouring teeth.
2) They make cleaning around the retaining teeth a little more difficult and require good oral hygiene.
Adhesive Bridges
These are false teeth that are bonded to one or two neighbouring teeth by small wings that fit discretely on the inside surface of the retaining teeth.
The advantages are:
1) Very little or no drilling of neighbouring teeth is needed.
2) They are more conservative than a fixed bridge.
The disadvantages are:
1) The bonding can sometimes fail allowing the bridge to come out.
2) Generally have a shorter life span than a fixed bridge.
3) Generally unavailable for back teeth or large gaps.
