A dental bridge typically lasts between 10 and 15 years; with excellent home care and regular professional check-ups, a lifespan of 20 years or more is entirely achievable. At Fitzroy Dental Practice, a CQC-registered, five-generation practice at 14 Fitzroy Square in Fitzrovia, we treat patients from across London who ask exactly this question before committing to treatment. In the sections below, we cover realistic lifespan benchmarks, daily maintenance routines, the warning signs that a bridge may be failing, and when dental implants might be worth considering as an alternative.
What Is a Dental Bridge, and How Does It Work?
A dental bridge is a fixed prosthetic restoration designed to replace one or more missing teeth. It consists of one or more artificial teeth called pontics held in place by dental crowns that are cemented onto the healthy teeth on either side of the gap (the abutment teeth). Because it is fixed, a bridge can only be removed by a dental professional, which distinguishes it from a removable partial denture.
The most common types of bridge available at our London practice include:
- Traditional bridge crowns on both neighbouring teeth; the strongest option, typically used for back-of-mouth gaps.
- Cantilever bridge supported by a single abutment tooth; used where only one adjacent tooth is present.
- Maryland (resin-bonded) bridge ceramic or metal wings bonded to the backs of neighbouring teeth with minimal tooth preparation; commonly chosen for front teeth.
- An implant-supported bridge anchored to dental implants rather than natural teeth; it avoids preparing healthy adjacent teeth and preserves jawbone volume.
We assess each patient individually to recommend the most suitable bridge type for their clinical situation and aesthetic goals.
How Long Does a Dental Bridge Last? Realistic Lifespan Expectations
The longevity of a dental bridge depends primarily on its type, the materials used, and how conscientiously it is maintained. The table below provides an at-a-glance summary:
| Bridge Type | Average Lifespan | Key Longevity Factor | Bone Preserved? |
|---|---|---|---|
| Traditional bridge | 10–15 years (up to 20+) | Oral hygiene & abutment health | No |
| Maryland (resin-bonded) | 5–10 years | Wing bonding integrity | No |
| Cantilever bridge | 10–15 years | Load on a single abutment | No |
| Implant-supported | 15–20+ years | Osseointegration & bone density | Yes |
Factors that influence lifespan
Beyond bridge type, the following factors play a significant role:
- Oral hygiene, including daily flossing beneath the pontic and twice-daily brushing, is the single most important determinant of longevity.
- Material choice: All-ceramic bridges offer superior aesthetics; metal-ceramic options provide greater fracture resistance in high-load areas.
- Bruxism, or teeth grinding, places enormous stress on the bridge structure and its abutment teeth. A custom night guard from our Fitzrovia practice can significantly reduce this risk.
- Abutment tooth health decay or gum disease in the supporting teeth is the leading cause of early bridge failure.
- Diet hard foods (crusty bread, nuts, ice), sticky sweets, and chewing gum all place excessive load on the bridge cementation.
Regular dental check-ups and routine examinations allow early detection of problems before they escalate into costly failures.
How Do You Maintain a Dental Bridge to Make It Last Longer?
Daily home care
Standard dental floss cannot reach beneath the pontic, so a floss threader or interdental brush is essential for cleaning the area where the artificial tooth meets the gum. Water flossers (oral irrigators) are an excellent supplementary tool for flushing food debris from this hard-to-reach space. Brush with a soft-bristled toothbrush and fluoride toothpaste for two minutes twice daily, paying careful attention to the gumline around the abutment crowns. An antibacterial mouthwash can further reduce the bacterial load at the gingival margin.
Professional maintenance
Most bridge patients benefit from a dental check-up every six months, though those with a history of gum disease may require more frequent visits. At a bridge review appointment, our team at 14 Fitzroy Square will assess your bite, examine the abutment teeth for signs of decay, review gingival health, carry out a professional polish, and take an X-ray if clinically indicated. Patients from Fitzrovia, Bloomsbury, and Marylebone consistently tell us how valuable these reviews are in providing peace of mind.
Warning Signs That Your Dental Bridge May Need Replacing
Contact your dentist promptly if you notice any of the following:
- Pain or sensitivity beneath the bridge may indicate decay developing on the abutment tooth under the crown.
- A loose or rocking bridge cementation has failed; if left untreated, bacteria can rapidly colonise the exposed margins.
- Visible cracks or chips in the porcelain structural integrity is compromised, and the fracture can extend further.
- A dark line at the gumline, the metal substructure may be showing, often accompanied by gum recession.
- Persistent bad breath or an unpleasant taste, trapped plaque and food debris beneath the pontic are common culprits.
- A change in your bite, the bridge may have shifted, accelerating uneven wear on opposing teeth.
- Swollen or bleeding gums around the bridge are a potential sign of peri-abutment gum disease that requires prompt assessment.
Avoid over-the-counter dental cement as anything more than a very temporary measure; it can mask worsening decay and delay essential treatment. If you are based in London and experiencing any of these signs, our Fitzrovia practice offers prompt assessment appointments. Call us on 020 7387 3317.
Dental Implants and Bridges: Which Is the Better Long-Term Choice?
Both options can restore function and aesthetics after tooth loss, but they differ considerably in how they work and how long they last. The comparison table below summarises the key differences:
| Factor | Traditional Bridge | Dental Implant | Implant-Supported Bridge |
|---|---|---|---|
| Lifespan | 10–15 years | 15–25+ years | 15–20+ years |
| Bone preservation | No | Yes | Yes |
| Tooth prep required | Yes (abutments) | No | No |
| Relative cost | Lower | Higher | Highest |
| Recovery time | 2–3 appointments | 3–6 months | 3–6 months |
A traditional bridge may be the right choice when adjacent teeth already require crowning, when insufficient jawbone density rules out implant placement without grafting, or when a patient wishes to avoid surgery. A dental implant or implant-supported bridge is generally preferable when the adjacent teeth are healthy and should not be prepared unnecessarily, or where preserving jawbone volume over the long term is a priority. Many patients who began with a bridge later transition successfully to implants; having a bridge does not prevent future implant treatment.
How Much Does a Dental Bridge Cost in London?
Dental bridge costs in London vary according to bridge type, material, and the complexity of preparation involved. As a general guide, a traditional porcelain bridge typically ranges from £800 to £2,500 or more per unit; a Maryland bridge is usually lower, given the minimal tooth preparation required. Implant-supported bridges entail additional implant surgery costs and are the most expensive of the three options.
At Fitzroy Dental Practice, costs are also influenced by the number of pontics needed, whether any preliminary treatment (such as fillings or periodontal therapy) is required before bridge placement, and the material selected, zirconia, for example, offers exceptional durability and aesthetics at a premium.
NHS provision for dental bridges is available but limited in scope and material choice. Private treatment allows full porcelain options, a wider choice of design, and a fully customised aesthetic result. We also offer 0% interest-free finance spread over 12 months, with no upfront payment required and a straightforward online application. Full details and our current fee guide are available on the website.

Frequently Asked Questions
How long does a dental bridge last?
On average, 10–15 years; with diligent care and regular professional check-ups, 20 years or more is achievable.
How do you clean a dental bridge?
Use a floss threader or interdental brush beneath the pontic every day, alongside regular brushing with a soft-bristled toothbrush and fluoride toothpaste.
What is the difference between dental implants and bridges?
Implants replace the tooth root, preserve jawbone volume, and do not require preparation of adjacent teeth. Bridges span the gap using neighbouring teeth as anchors and are generally a lower initial investment.
Can a dental bridge be repaired?
Minor porcelain chips may be repaired chairside. Significant fractures or failed cementation usually necessitate replacement of the bridge.
Is a dental bridge available on the NHS?
Yes, though NHS provision is limited in material choice and aesthetics. Private treatment offers greater flexibility in design and materials.
