Losing a tooth does more damage than most people realise. The gap changes how you chew. Neighbouring teeth start drifting into the space over months and years. The bone underneath gradually shrinks. And the longer you leave it, the more complicated and expensive the fix becomes.
A dental bridge is one of the most established ways to deal with that gap. But it’s not the only way, and it’s not always the right way. At Conder Dental Centre, we’d rather give you an honest picture than a quick recommendation so here’s what’s actually involved.
KEY TAKEAWAYS
A dental bridge fills a tooth gap using crowns on neighbouring teeth as anchors, with an artificial tooth suspended between them.
The four main types are: traditional, cantilever, Maryland, and implant-supported, each suited to different situations.
Traditional bridges require permanently reducing healthy adjacent teeth. That trade-off is irreversible and worth understanding upfront.
Bridges typically last 10–15 years with good maintenance; implants often last 20+ years but involve surgery and a longer process.
Bone loss under the gap continues with a conventional bridge, only an implant (or implant-supported bridge) addresses this.
Cost is lower upfront for bridges, but that advantage narrows over 15–20 years when you account for replacements and adjunct treatment.
What Exactly Is a Dental Bridge?
A dental bridge is a fixed restoration — you can’t take it out. It spans the gap left by a missing tooth using three or more connected units: crowns that cap the teeth on either side of the gap (called abutment teeth), and an artificial tooth the pontic suspended in the middle.
Once it’s cemented in, a bridge looks and functions like natural teeth. You eat with it, clean around it, and forget it’s there for the most part. It’s a long-standing solution dentists have been placing bridges for well over a century and when planned correctly, it works reliably. Our restorative treatment covers the full range of options if you want a broader starting point.
The Four Types of Dental Bridges
Traditional Bridge
The most common type by far. The teeth on both sides of the gap are permanently reduced in size filed down to create a strong base for the bridge crowns. Those anchor teeth will always need crowns after this point; the reduction is irreversible.
Traditional bridges are strong, proven, and work well for most gaps in the back and middle of the mouth. They’re the right choice when the neighbouring teeth already need crowns for other reasons, or when there isn’t enough bone for an implant without additional surgery.
Cantilever Bridge
Used when there’s only one available anchor tooth beside the gap, usually at the very back of the mouth. Because all the force goes through a single support, it’s less commonly placed and carefully selected it’s not suitable for every situation.
Maryland Bridge
A more conservative option. Instead of full crown preparation, the pontic is held in place by thin porcelain or metal wings bonded to the backs of the adjacent teeth. No filing down required.
Maryland bridges work well for front teeth where bite forces are lighter. They’re not suited to back teeth, and they can debond over time. For the right patient in the right location, though, they’re a smart, tooth-preserving choice.
Implant-Supported Bridge
When multiple adjacent teeth are missing, or when you’d prefer not to reduce healthy neighbouring teeth at all, an implant-supported bridge is worth serious consideration. Dental implants act as the anchors instead of your natural teeth and they also stimulate the jawbone beneath the gap, which conventional bridges don’t do. If you’re weighing this option, our posts on dental implants in Canberra and how long dental implants actually last are worth reading alongside this one.
The Trade-Off You Should Understand Before You Decide
None of that means a bridge is the wrong choice. Sometimes it’s clearly the right one. But it’s a decision that deserves proper context — not just a quick plan because the bridge quote came back cheaper than the implant.
The situations where a traditional bridge often makes real sense: the neighbouring teeth already need crowns for their own reasons; there’s insufficient bone for an implant without a graft; a patient genuinely wants to avoid surgery; or time is a factor (a bridge can typically be completed in two visits, while an implant takes several months).
Dental Bridge vs Implant
The implant is self-contained. It sits in the jaw, doesn’t involve the neighbouring teeth, and maintains the bone underneath. A conventional bridge relies on adjacent teeth for support and leaves the bone under the gap to resorb over time which can eventually cause the gum to sink and affect the aesthetic result. Our guide on how dental implants improve overall health goes into more detail on the bone preservation side.
Cost-wise: a bridge is cheaper upfront. Over 15–20 years, that gap narrows when you factor in potential bridge replacement, any additional treatment the abutment teeth may need, and the long-term effects of bone loss. An implant placed well has a realistic lifespan of 20+ years with proper maintenance.
Neither option is categorically superior. The right answer depends on the specific teeth involved, your bone volume, your budget, your timeline, and what matters most to you. That’s the conversation we have at your consultation with X-rays in front of us, not hypothetically.
How Long Do Dental Bridges Last?
A well-maintained bridge typically lasts 10–15 years, sometimes longer. Three things determine longevity: the quality of the original placement, how consistently you clean beneath the pontic, and whether you grind your teeth at night (bruxism puts significant stress on bridges and shortens their lifespan). If you’ve been told you grind, it’s worth discussing that before any fixed restoration see our post on how dental crowns can save your smile for some relevant context on protecting restorations from grinding forces.
The most common reason bridges fail early is plaque buildup at the gum line where the crown meets the tooth usually because cleaning under the pontic gets skipped. A water flosser, floss threader, or superfloss used daily makes a real difference. We check bridge margins at every check-up, so if anything is shifting, we catch it before it becomes a problem.
For detailed guidance on daily maintenance once your bridge is in place, our post on caring for dental bridges and crowns covers exactly what the routine should look like.
Frequently Asked Questions
Does getting a bridge hurt?
The preparation is done under local anaesthetic, so there’s no pain during the procedure itself. Some sensitivity on the prepared teeth for a few days after is normal, that settles once the permanent bridge is cemented and seated properly.
Can I eat normally with a bridge?
Yes, after the initial settling-in period. Most people eat completely normally. Very sticky foods (like caramel or chewing gum) and extremely hard foods are worth avoiding, they can stress the bridge or the cement. Day-to-day eating, including chewing on that side, is absolutely fine.
How do I actually clean under a dental bridge?
Brushing around the bridge is necessary but not enough on its own, you also need to get under the pontic where it rests against the gum. A floss threader, superfloss, or water flosser all do the job well. We’ll walk you through the technique at your fitting appointment so there’s no guesswork.
Can a bridge still be done if the gap has been there for years?
Yes. But a long-standing gap means the bone and gum underneath have changed — the bone has shrunk and the gum contour may have receded. That can affect how the final result looks, particularly in visible areas. We’d assess this properly at your consultation and factor it into the plan. Sometimes additional shaping or tissue management is needed for a good cosmetic outcome.
