A dental bridge does exactly what its name suggests — it bridges the gap left by one or more missing teeth, using an artificial tooth anchored to the natural teeth (or implants) on either side. It's one of the oldest and most established tooth-replacement options in dentistry, and for the right situation, it's still one of the best.
Below, our Sudbury team explains the different types of bridges, what getting one actually involves, and where a bridge makes more or less sense than an implant or a denture.
1 What Is a Dental Bridge?
A dental bridge is a fixed (non-removable) dental restoration that replaces one or more missing teeth. It consists of an artificial tooth — called a pontic — fused between two crowns that fit over the natural teeth on either side of the gap, called abutment teeth. Once cemented into place, the whole structure functions as a single, solid unit that isn't taken in and out the way a denture is.
Bridges have been used in dentistry for well over a century, long before implants existed, and they remain a well-established, predictable option today — particularly when the teeth next to a gap already need crowns for other reasons, which can make a bridge a genuinely efficient solution rather than a compromise.
2 Who's a Good Candidate?
A bridge tends to make the most sense when a few specific conditions line up:
- ✓ One to three missing teeth in a row, with healthy, strong teeth (or dental implants) available on both sides to anchor the bridge.
- ✓ Abutment teeth that are structurally sound or already need crowns — reducing them for a bridge is a much easier decision when they aren't otherwise pristine, untouched teeth.
- ✓ A preference for a fixed, non-removable option over a removable partial denture, without wanting the longer timeline or surgery an implant requires.
- ✓ Healthy gum tissue around the abutment teeth, since a bridge relies on those teeth staying stable for years.
If the teeth on either side of the gap are otherwise perfectly healthy, we'll often walk through an implant as an alternative too — since a traditional bridge does require permanently altering those healthy teeth, which is worth weighing carefully.
3 Types of Dental Bridges
Not all bridges are built the same way — the right type depends on where the gap is, how many teeth are missing, and the condition of the surrounding teeth.
Traditional Bridge
A crown on each side of the gap anchors the pontic. The most common type, and the most durable.
Cantilever Bridge
Anchored by a crown on only one side — used when there's just one adjacent tooth available. Less common, since it places more stress on a single abutment.
Maryland Bridge
Metal or porcelain wings bond to the back of adjacent teeth instead of full crowns — far less tooth reduction, but less durable under bite force.
A fourth option, an implant-supported bridge, replaces multiple missing teeth using two dental implants as the anchors instead of natural teeth — it avoids putting any load on your remaining teeth at all, and we cover it in more detail in our dental implants guide.
4 The Process, Step by Step
Compared to an implant, a traditional bridge is a relatively quick process — typically completed over two visits spaced a couple of weeks apart, with no surgery involved.
- ✓ Visit one: the abutment teeth are reshaped to make room for their crowns, impressions are taken, and a temporary bridge is placed to protect the prepared teeth while the permanent one is fabricated.
- ✓ In the lab: your permanent bridge is custom-made to match the shape, size, and shade of your natural teeth — this typically takes two to three weeks.
- ✓ Visit two: the temporary bridge is removed, the permanent bridge is checked for fit and bite, and it's cemented securely into place.
Compared to an implant's multi-month timeline, a traditional bridge is usually complete within three to four weeks from your first visit — one of its clearest practical advantages.
5 Advantages of a Dental Bridge
"Bridges get overshadowed by implants in a lot of dental marketing, but they're still the right call for plenty of patients — especially when the teeth next to a gap already need crowns, or when someone wants a fixed solution without the longer implant timeline."
Dr. Derek Lewis, DDS — Long Lake Family Dentistry- ✓ Fixed in place — unlike a removable partial denture, a bridge isn't taken out, so it feels closer to a natural tooth day to day.
- ✓ Restores full bite function and stops neighbouring teeth from drifting into the empty space over time.
- ✓ Faster overall timeline than an implant — typically complete in a few weeks rather than several months.
- ✓ No surgery required for a traditional or Maryland bridge, making it accessible to patients who aren't candidates for or don't want implant surgery.
- ✓ Often a lower upfront cost than an implant, particularly a single-tooth traditional bridge.
6 Disadvantages & Limitations
A bridge's biggest trade-offs come from what it relies on: the health of the teeth next to the gap.
✅ Where Bridges Win
- Fixed, non-removable, natural feel
- Faster treatment timeline
- No surgery for traditional/Maryland types
- Efficient when abutment teeth need crowns anyway
⚠️ Real Trade-Offs
- Requires reducing healthy abutment teeth
- Doesn't stop jawbone loss under the gap
- A problem with an abutment tooth can jeopardize the whole bridge
- Shorter typical lifespan than an implant
That second point is worth explaining: because nothing is placed inside the jawbone itself, a traditional bridge doesn't stimulate the bone the way a tooth root — or an implant — does. Some bone loss under the missing tooth's gap can continue slowly over time, which is one of the main clinical differences from an implant.
7 How Long Do Bridges Last?
With good care, a traditional bridge commonly lasts 10 to 15 years, and many last considerably longer. Implant-supported bridges tend to last the longest — often 15 to 20 years or more, since they don't rely on natural teeth that can develop their own problems over time. Maryland bridges, because they're bonded rather than fully cemented over a crown, typically have a shorter lifespan of around 5 to 10 years.
Traditional Bridge
~10–15 years with good care and regular checkups.
Implant-Supported
~15–20+ years — typically the longest-lasting bridge option.
Maryland Bridge
~5–10 years — shorter due to its bonded, less retentive design.
A bridge's actual lifespan depends heavily on how well the abutment teeth are cared for — since those teeth are doing the structural work of holding the bridge in place, decay or gum disease affecting them can shorten the bridge's life significantly.
8 Caring for a Bridge
The trickiest part of caring for a bridge is cleaning underneath the pontic — the area where a normal floss strand can't easily reach, since the artificial tooth is fused to its neighbours rather than having a natural gap around it.
- ✓ Use a floss threader, pre-threaded "super floss," or a water flosser to clean underneath the pontic daily — plaque trapped there is a leading cause of problems developing at the abutment teeth.
- ✓ Brush normally, paying extra attention to the gumline around each abutment crown.
- ✓ Keep up with regular checkups — we check the fit and the health of the abutment teeth at each visit, since a bridge's lifespan depends entirely on them.
- ✓ Avoid using the bridge to bite into very hard foods — ice, hard candy, or popcorn kernels can chip a pontic or crack a crown.
9 Bridges vs. Implants vs. Dentures
A bridge sits in the middle ground between the two other common options — more permanent than a denture, but faster and less invasive than an implant.
- ✓ Choose a bridge when you want a fixed solution on a faster timeline, without surgery, and the adjacent teeth are healthy enough to support it.
- ✓ Choose an implant when you want the longest-lasting option and don't want to alter the healthy teeth next to the gap.
- ✓ Choose dentures when several or all teeth need replacing and a non-surgical, more budget-friendly option is the priority.
We cover implants and dentures in their own dedicated guides, linked above, if you're weighing more than one option before your consultation.
10 Warning Signs Something's Wrong
A well-fitted bridge shouldn't cause ongoing discomfort. Here's what shouldn't be ignored:
A bridge that feels loose
May mean the cement has broken down or an abutment tooth has developed a problem underneath the crown.
Bleeding or swollen gums nearby
Often a sign plaque has built up under the pontic or around an abutment crown.
Pain when biting down
Can indicate the bite is off, or that an abutment tooth needs attention.
Persistent bad taste or odour
Sometimes points to decay developing under the bridge, which isn't always visible.
A bridge that has come loose or fallen out entirely should be seen promptly — the exposed abutment teeth are vulnerable in the meantime.
See Emergency Care →11 Quick Checklist
A bridge is worth discussing with us if:
- ✓ You're missing one to three teeth in a row, with healthy teeth on both sides of the gap
- ✓ You want a fixed, non-removable option rather than a partial denture
- ✓ You'd prefer a faster timeline over an implant's multi-month process
- ✓ The teeth next to your gap already need crowns, or you're comfortable having them reshaped
- ✓ You're prepared to clean under the pontic daily to protect the abutment teeth long-term
An exam will confirm whether your specific gap and the surrounding teeth are a good match for a bridge, an implant, or a partial denture.
