What Is The Cost Of Replacing A Dental Bridge?
A dental bridge is a durable and effective solution for replacing missing teeth. With proper care, a high-quality bridge can last for 10 to 15 years or even longer. However, like all dental restorations, it will not last forever. Over time, a bridge can wear down, become damaged, or the supporting teeth can develop problems. When this happens, the bridge will need to be replaced. This guide will explore the cost of replacing a dental bridge, the reasons why replacement is necessary, and the factors that influence the final price.
Understanding Why Dental Bridges Need Replacement
A dental bridge is a strong restoration, but it is subject to the same forces as your natural teeth. Several common issues can lead to the need for a replacement.
1. Recurrent Decay
This is the most common reason for bridge failure. A bridge is supported by the teeth on either side of the gap. These teeth are covered by crowns, which are cemented onto them. Over time, the margin where the crown meets the natural tooth can break down. If bacteria get under the crown, decay can develop on the supporting tooth. If this decay is not caught early, it can destroy the tooth’s structure, causing the bridge to fail.
2. Wear and Tear
The artificial teeth (pontics) and the crowns of a bridge are made of porcelain or ceramic. While strong, these materials can chip, crack, or wear down over time, especially in patients who grind their teeth.
3. Gum Disease and Bone Loss
If the gums around the bridge become diseased, the supporting teeth can lose bone support. This can cause the bridge to become loose. If the bone loss is severe, the supporting teeth may even be lost, making the bridge unusable.
4. Fracture of the Bridge
A hard impact or biting down on something very hard can fracture the framework of the bridge. This is especially true for older bridges with a porcelain-fused-to-metal framework, where the porcelain can chip away from the metal.
5. Aesthetic Concerns
Sometimes, a bridge is replaced for cosmetic reasons. The gums may have receded, exposing the margin of the bridge and making it look unsightly. Or, a patient may simply want to upgrade to a more modern, natural-looking all-ceramic bridge.
The Average Cost of Replacing a Dental Bridge
The cost of replacing a dental bridge is similar to the cost of getting a new bridge. The price depends on the material used, the number of teeth being replaced, and the condition of the supporting teeth.
In the UK, you can expect to pay anywhere from £800 to £3,500 or more for a replacement bridge.
- Porcelain Bonded to Metal (PBM) Bridge: This is a common and reliable option, costing between £800 and £1,500 for a three-unit bridge.
- All-Ceramic Bridge (Zirconia or E-max): These offer superior aesthetics and cost between £1,500 and £3,500+ for a three-unit bridge.
These are private costs, as bridge replacement for cosmetic reasons is not typically available on the NHS. The NHS will only provide a replacement if it is deemed clinically necessary to secure oral health.
Factors That Influence the Cost
The final cost of your replacement bridge is determined by several key factors.
1. The Reason for Replacement
This is the most critical factor. If the bridge simply wore out and the supporting teeth are healthy, the replacement process is straightforward. However, if the bridge failed due to decay or gum disease on the supporting teeth, those issues must be treated first. You may need a filling, a root canal, or even an extraction on a supporting tooth before a new bridge can be made. These additional procedures will add to the total cost.
2. The Type of New Bridge
As mentioned, the material you choose for your new bridge is a primary cost driver. A high-aesthetic, all-ceramic bridge will cost more than a standard porcelain-fused-to-metal bridge.
3. The Number of Units
A bridge is priced by the unit. A three-unit bridge (two crowns and one false tooth) is the most common. If you are replacing a bridge that spanned a larger gap, the new bridge will have more units and will cost proportionally more.
4. The Need for a Temporary Bridge
While your new bridge is being made in the laboratory, you will need a temporary bridge to protect the prepared teeth. The cost of this temporary restoration is usually included in the overall fee, but you should confirm this.
5. The Location and Expertise
The location of the dental practice and the skill of the dentist are standard factors that influence cost.
Cost Comparison: Replacing a Bridge vs. Alternatives
When a bridge fails, it is an opportunity to reassess your options. The best solution for you may not be another bridge. The table below compares the cost and value of replacing a bridge with alternative treatments.
| Treatment Option | Average Cost (UK) | Pros | Cons |
|---|---|---|---|
| Replacement Bridge | £800 – £3,500+ | No surgery required; faster than implants. | Requires support from adjacent teeth; may fail again. |
| Dental Implant(s) | £2,500 – £3,500 per tooth | Independent support; prevents bone loss; lasts a lifetime. | More expensive; requires surgery; longer treatment time. |
| Partial Denture | £500 – £1,800 | Most affordable option; removable. | Less stable; can be uncomfortable; not a fixed solution. |
Important Note: If your bridge has failed, your dentist will discuss all available options with you. A dental implant is often considered the gold standard because it is independent and does not put stress on other teeth. However, a new bridge is still an excellent and reliable option for many patients.
How to Save Money on a Replacement Bridge
Replacing a bridge is a significant investment, but there are ways to manage the cost.
- Join a Dental Plan: A private dental membership plan often provides a 10-20% discount on restorative treatments like bridges.
- Explore Finance Options: Most private practices offer payment plans, allowing you to spread the cost over several months or years.
- Prioritise Oral Hygiene: The best way to avoid the cost of replacement is to make your current bridge last as long as possible. Clean under the bridge daily with superfloss or an interdental brush, and see your dentist for regular check-ups.
- Get Multiple Quotes: Compare prices and treatment plans from different dentists.
What to Expect During the Replacement Process
The process of replacing a bridge is similar to getting a new one.
- Examination: The dentist will examine the old bridge and the supporting teeth, taking X-rays to assess the underlying bone and root health.
- Removal of Old Bridge: The old bridge is carefully cut and removed.
- Treatment of Supporting Teeth: Any decay or damage to the supporting teeth is treated. The teeth are then prepared for the new crowns.
- Impressions: Moulds of your teeth are taken and sent to the dental laboratory.
- Temporary Bridge: A temporary bridge is cemented in place to protect your teeth.
- Fitting: Once the new bridge is ready, the temporary is removed, and the new bridge is tried in, checked, and cemented into place.
Frequently Asked Questions (FAQ)
Q: How long does it take to replace a bridge?
A: The process typically takes two to three weeks, spread over two main appointments. The first appointment is for preparing the teeth and taking impressions. The second is for fitting the new bridge.
Q: Is replacing a bridge painful?
A: No. The procedure is carried out under local anaesthetic, so you will not feel pain. You may experience some temporary sensitivity after the teeth are prepared.
Q: Can a broken bridge be repaired instead of replaced?
A: In some cases, a minor chip or crack in the porcelain can be repaired with a composite bonding material. However, for major fractures or if the supporting teeth are compromised, a full replacement is usually necessary.
Q: What happens if I do not replace a failed bridge?
A: Leaving a gap can cause the adjacent teeth to shift and tip into the space. This can lead to bite problems and make future replacement more difficult. A failed bridge can also trap food and bacteria, leading to further decay and gum disease.
Q: Will my dental insurance cover a replacement bridge?
A: It depends on your specific policy. Many policies cover a portion of the cost of restorative treatments like bridges. Check with your insurer to understand your coverage.

Conclusion
The cost of replacing a dental bridge in the UK is comparable to the cost of a new bridge, ranging from £800 to over £3,500. The final price is heavily influenced by the reason for failure and the condition of the supporting teeth. While managing the cost is important, a failed bridge should not be ignored, as it can lead to further dental problems. By understanding your options, you can invest in a solution that restores your smile and protects your oral health for the long term.
