Bridge is a single word covering four quite different designs, and the real difference between them is how much of your healthy neighboring teeth they consume.
The four types
Which are realistic for you depends on the gap position, the condition of the neighboring teeth, and the bite forces on that part of the mouth.
| Type | How it is supported | Neighboring teeth | Best suited to |
|---|---|---|---|
| Traditional | Crowns on the teeth either side | Both are trimmed down | Neighbours that already need crowns |
| Cantilever | A crown on one side only | One is trimmed down | Limited cases; not for heavy bite forces |
| Maryland (resin-bonded) | Wings bonded to the backs of neighbours | Minimal or no preparation | Front teeth; conservative option |
| Implant-supported | Implants rather than natural teeth | Untouched | Longer spans; preserving healthy neighbours |
The question that usually decides it
Are the teeth either side of the gap already crowned or heavily filled? If they are, a traditional bridge uses teeth that already need work, and the main argument against it disappears.
If they are pristine, trimming them down to carry a bridge is a genuine cost — and that is the case where an implant most often wins. See implant versus bridge.
Living with a bridge
A bridge is one connected unit, which changes how it is cleaned and how it fails.
- Cleaning under the false tooth is essential and needs specific tools
- Decay at the margins of the supporting crowns is the usual failure mode
- If one support fails, the whole bridge usually needs replacing
- Regular checks matter because problems start where you cannot see
Common questions
What people ask before scheduling
How long does a bridge last?
Well-made bridges commonly serve for many years, with longevity depending on the supporting teeth, the bite and how well the margins are cleaned. No dentist can promise a number of years.
Is a Maryland bridge as strong?
It is more conservative but less suited to heavy bite forces, and debonding is its common failure mode. It is most often used for front teeth.
Can a bridge replace more than one tooth?
Yes, though longer spans place more load on the supports. Beyond a certain span, implants generally become the more predictable option.
What happens if a supporting tooth decays?
Usually the whole bridge has to be replaced, and sometimes the plan changes entirely if that tooth cannot be saved. This is why margin cleaning matters so much.
Is a bridge cheaper than an implant?
Often lower up front. Over a longer horizon the comparison narrows, particularly if the bridge needs replacing and the supporting teeth have been consumed. Compare the complete plan, not the first invoice.
