Short answer
A bridge that is loose, cracked, painful or has decay under it usually needs to be removed and replaced, not just re-glued. Depending on the health of the supporting teeth, the new option may be another bridge, a single dental implant or a partial denture. Our self-pay price for a 3-unit bridge starts at $3,499, and we give you a written estimate before any work starts.
How long does a dental bridge last?
Many bridges last 10 years or more, and some last much longer. Lifespan depends on how well the supporting teeth and gums are cared for, how hard you bite or grind, and how the bridge was made. The weak spot is usually not the false tooth itself but the natural teeth underneath the crowns that hold it.
What are the signs a bridge is failing?
- The bridge feels loose or moves when you chew
- A bad taste or smell comes from under it
- Pain, pressure or sensitivity in one of the anchor teeth
- Visible cracks or chips in the porcelain
- A dark line or gap appears at the gumline
- Food packs under the false tooth more than it used to
- Swollen or bleeding gums around the bridge
Decay at the edge of an anchor crown is one of the most common reasons bridges fail. Because it hides under the bridge, it can grow for a while before it hurts, which is why regular exams and X-rays matter.
Can an old bridge just be re-cemented?
Sometimes. If the bridge came loose but the teeth under it are healthy and the fit is still good, we may be able to clean it and cement it back. More often, a loose bridge is a sign of decay or a broken tooth underneath. In that case, re-cementing would trap the problem, and replacing it is the safer choice.
What are your options for replacing a bridge?
| Option | Best when | Things to know |
|---|---|---|
| New fixed bridge | Anchor teeth are still strong | Anchor teeth are prepared again; from $3,499 self-pay for 3 units |
| Single dental implant | One tooth is missing and bone is healthy | Doesn’t rely on neighboring teeth; takes months to heal |
| Partial denture | Several teeth are missing or anchors are weak | Removable; from $1,399 self-pay |
| Anchor tooth repair first | An anchor tooth has decay or infection | May need a filling, root canal or extraction before a new bridge |
We place and restore single implants in our office. For a long span of missing teeth or very weak anchors, a partial denture is often the most practical fix. Full-arch implant options are not something we offer.
What happens when we replace a bridge?
- Exam and X-rays. We check the anchor teeth, gums and bone, and talk through your options and costs.
- Removing the old bridge. The tooth is numbed with local anesthetic and the old bridge is carefully cut off.
- Treating what’s underneath. Decay is removed and teeth are rebuilt. Some teeth may need root canal treatment first.
- Impressions and a temporary. We record your bite and shade, and you wear a temporary bridge while the new one is made at the lab.
- Fitting the new bridge. We check the fit, color and bite, then cement it in place.
Most replacements take two visits, with the new bridge placed about 5 days after the first visit, once it comes back from the lab. If an anchor tooth needs extra treatment, plan for more time. We do not make same-day crowns or bridges; our post on same-day crowns explains how our two-visit process works.
How do you make a new bridge last longer?
- Clean under the false tooth every day with a floss threader, super floss or a small brush.
- Brush twice a day with fluoride toothpaste.
- Wear a night guard if you grind your teeth.
- Avoid chewing ice, hard candy or pens.
- Keep regular cleanings so we can catch decay at the edges early.

Frequently asked questions
It depends on the teeth around the gap and the bone where the tooth is missing. An implant avoids reshaping neighboring teeth, while a bridge is quicker. We explain the trade-offs for your mouth at your exam.
Many PPO plans help pay to replace a bridge after a set number of years. We verify your benefits before treatment; see our insurance page.
You can, but nearby teeth may drift and the opposing tooth can over-erupt into the space. That can change your bite and make future treatment harder.
The area is numbed with local anesthetic, so most people feel pressure rather than pain. Some gum soreness for a few days afterward is common.
