A dental bridge usually lasts 10 to 15 years, and many last 20 years or more with good home care and regular checkups. Bridges don’t fail suddenly in most cases. They wear out slowly, most often because of decay or gum disease around the supporting teeth, which is a common and preventable problem. If your bridge feels loose, smells bad, or hurts when you bite, that’s a sign to have it checked, and our team can review all your options for removable dentures and fixed bridges at the same visit.
A lot of people worry that a bridge is a “temporary” fix. A well-made bridge is a long-term restoration, and its lifespan depends on the health of the teeth holding it up. The crowns that anchor a bridge are made with the same care as any other crown, and our single visit crowns and veneers technology (CEREC) lets us design and mill ceramic restorations right in the office.
If you’re comparing options for a missing tooth, it’s worth knowing how bridges stack up against dental implants, which don’t rely on neighbouring teeth for support. Both are good options, and they suit different mouths.
When something feels off with an existing bridge, don’t wait for it to fall out. You can use online booking to choose a time that suits you, and our dental clinic in Woodbridge is easy to reach from anywhere in Vaughan.
Dental bridge lifespan at a glance
- Traditional fixed bridge: about 10 to 15 years, often longer
- Implant-supported bridge: often 15 to 25 years or more
- Resin-bonded (Maryland) bridge: about 5 to 10 years
- Cantilever bridge: about 10 years, depends heavily on bite forces
What is a dental bridge?
A dental bridge is a fixed restoration that replaces one or more missing teeth by joining an artificial tooth (called a pontic) to crowns on the teeth next to the gap. Those supporting teeth are called abutments. The whole unit is cemented in place and doesn’t come out.
It’s called a bridge because it literally spans the gap, resting on the teeth at each end like a small bridge rests on its supports.
What are the main types of dental bridges?
- Traditional bridge: crowns on both neighbouring teeth hold a false tooth in the middle. This is the most common type.
- Cantilever bridge: supported by a crown on only one side. Used in specific situations where forces are low.
- Maryland (resin-bonded) bridge: a false tooth with small metal or ceramic wings bonded to the backs of neighbouring teeth. Needs very little tooth preparation, often used for front teeth.
- Implant-supported bridge: anchored to dental implants instead of natural teeth. Common when several teeth in a row are missing.
What affects how long a bridge lasts?
Research on fixed bridges consistently shows high survival rates at 10 years, often reported around 90%, with gradual declines after that. The biggest factors are things you and your dental team can control.
1. Health of the supporting teeth
Decay at the edge of an abutment crown is the most common reason bridges fail. Once decay gets under the crown, it can spread quietly until the tooth weakens or needs a root canal.
2. Gum health
Gum disease can loosen the supporting teeth by destroying the bone around them. A bridge is only as stable as the teeth holding it.
3. Cleaning under the pontic
Food and plaque collect under the false tooth. If that space isn’t cleaned daily, it leads to bad breath, gum inflammation, and decay on the abutments.
4. Bite forces and grinding
Clenching or grinding puts heavy stress on bridges, especially long-span or cantilever designs. Ceramics can chip and cement can wash out.
5. Material and fit
A precise fit at the margins (where the crown meets the tooth) seals out bacteria. Modern ceramics like zirconia and lithium disilicate are strong and natural-looking.
6. Length of the span
Replacing one tooth with a 3-unit bridge is more predictable than spanning 3 or 4 missing teeth.
What are the signs your bridge needs attention?
- The bridge feels loose or moves when you chew
- A bad taste or smell coming from under the bridge
- Pain, sensitivity, or pressure on one of the supporting teeth
- Swollen, bleeding, or receding gums around the bridge
- A visible gap or dark line at the edge of a crown
- A chip or crack in the porcelain
- Food packing under or around the bridge more than before
Some of these, like a loose bridge, need prompt attention. If the bridge comes off completely, keep it, avoid chewing on that side, and call the clinic. Don’t glue it back with household products.
How do you care for a dental bridge?
- Brush twice a day with a soft brush and fluoride toothpaste, angled toward the gumline.
- Clean under the pontic daily using a floss threader, superfloss, or interdental brush.
- Consider a water flosser to flush debris from under the bridge.
- Wear a night guard if you clench or grind.
- Avoid chewing ice, hard candy, and pen caps.
- Keep regular cleanings and checkups so the margins can be checked and X-rays can spot hidden decay.
- Limit sugary snacks and drinks between meals to protect the supporting teeth.
Dental bridge vs implant vs denture: how do they compare?
| Fixed bridge | Dental implant | Partial denture | |
|---|---|---|---|
| Typical lifespan | 10 to 15+ years | Implant often lifelong, crown 10 to 15+ years | 5 to 8 years |
| Affects neighbouring teeth | Yes, they’re crowned | No | Clasps rest on them |
| Removable | No | No | Yes |
| Bone preservation | Bone under the gap still shrinks | Helps preserve bone | Bone still shrinks |
| Treatment time | 1 to 3 weeks | 3 to 6 months | A few weeks |
| Surgery needed | No | Yes | No |
Bridges make the most sense when the neighbouring teeth already need crowns, when surgery isn’t a good option, or when you want a fixed result fairly quickly. Implants are often the better choice when the neighbouring teeth are healthy and untouched.
What happens when you get a bridge?
- Exam and X-rays to check the supporting teeth, roots, gums, and bone.
- Treatment planning, including material and shade selection.
- Preparation of the abutment teeth under local freezing.
- Digital scan of the area instead of messy impressions.
- Temporary bridge while the final one is made, or same-day design and milling for some ceramic cases.
- Fitting and cementing the final bridge, then checking your bite.
- Hygiene coaching on cleaning under the pontic.
How much of the neighbouring teeth is removed for a bridge?
For a traditional bridge, the abutment teeth are reshaped all the way around so the crowns fit over them, usually about 1 to 2 mm of tooth structure depending on the material. That change is permanent.
That’s why bridges are an especially good fit when those neighbouring teeth already have large fillings or need crowns anyway. If they’re untouched and healthy, an implant or a resin-bonded bridge may preserve more of your natural teeth. Your dentist should explain this trade-off clearly before you decide.
Can an old bridge be repaired, or does it need replacing?
It depends on what failed.
- Small porcelain chip: sometimes polished or repaired with composite.
- Loose bridge with healthy teeth: may be cleaned and re-cemented.
- Decay under a crown: usually means removing the bridge, treating the tooth, and making a new one.
- Cracked or lost supporting tooth: may need a longer bridge, implants, or a denture.
Common myths about dental bridges
“Bridges are outdated now that implants exist.”
Bridges are still a reliable, well-researched treatment and the right choice for many patients. Implants and bridges each have their place.
“If the bridge doesn’t hurt, it’s fine.”
Decay under a crown often causes no pain until it’s advanced. Regular X-rays catch it early.
“You can’t floss with a bridge.”
You can and should. Floss threaders, superfloss, and water flossers make it easy to clean under the false tooth.
“Getting a bridge is painful.”
Tooth preparation is done with local anaesthetic. Most people feel pressure and vibration, and mild sensitivity for a few days afterward.
Real patient situations
The 22-year bridge. A retiree had a 3-unit bridge placed in the early 2000s. With regular cleanings and daily threader use, it was still sound. Only minor polishing was needed.
The smell that wouldn’t go away. A woman noticed a bad taste near her bridge. X-rays showed decay under one abutment crown. The bridge was replaced, and the tooth was saved with a filling under the new crown.
The grinder. A man chipped the porcelain on his bridge twice. A night guard stopped the problem, and his new bridge has stayed intact.

Frequently asked questions
Can a dental bridge last a lifetime?
Some bridges last 20 to 30 years, but most need replacement at some point. Excellent cleaning, regular checkups, and protecting it from grinding give it the best chance.
Why does food get stuck under my bridge?
There’s a small space between the false tooth and the gum. Some food trapping is normal and is handled with daily threader or water flosser use. A sudden increase can mean the gum has changed or the bridge needs checking.
Is it normal for a new bridge to feel strange?
Yes. It can take a week or 2 to get used to the feel and bite. If your bite feels high or you have pain when chewing, the bridge may need a small adjustment.
Can you whiten a dental bridge?
No. Porcelain and zirconia don’t change colour with whitening. If you plan to whiten your natural teeth, do it before the bridge is made so the shades match.
Do bridges need to be replaced if the gums recede?
Not always. Mild recession may only expose a small edge. Recession that exposes root surfaces or causes sensitivity may mean the bridge should be redone for comfort and cleaning.
Conclusion
Most dental bridges last 10 to 15 years, and many last much longer.
The supporting teeth and gums decide how long a bridge survives, so daily cleaning under it matters.
Regular checkups and X-rays catch small problems before they cost you the bridge.
