Dental Bridges: How They Work and When They're the Right Fix
restorativedentistry
A closer look at dental bridges — the types, how they're made, and when a bridge beats an implant for replacing a missing tooth.
A bridge spans the gap left by a missing tooth by anchoring onto the teeth on either side. Here's how they work and when they're a strong choice.
How a bridge is built
The two neighbouring teeth are shaped to receive crowns. A lab (or in some cases a chairside mill) creates a single piece: two crowns joined to a replacement tooth, called a pontic, in the middle. It's cemented in and functions as one unit.
Types of bridges we use
- Traditional bridge — crowns on both neighbouring teeth, pontic in the middle. The workhorse.
- Cantilever bridge — anchored on one side only, used in specific low-force situations.
- Maryland bridge — bonded with small wings, often for a front tooth with healthy neighbours.
- Implant-supported bridge — anchored on implants rather than natural teeth, for larger gaps.
When a bridge is often the better fit
- The neighbouring teeth already need crowns or have large fillings
- You want the tooth replaced in days rather than months
- Bone volume or health history makes implants less predictable
- Cost is a significant factor
What to know about care
Bridges can't be flossed normally — you'll use a floss threader or water flosser under the pontic. Regular cleanings keep the anchor teeth healthy, which is what makes a bridge last.
