Before deciding how to replace one or more missing teeth, most patients face two options: a dental implant or a dental bridge. The price, the procedure, the longevity and the effect on the neighbouring teeth are entirely different. In this guide I honestly compare both solutions — without any sales pitch — so that you can make an informed decision.
The quick answer: which to choose?
In most cases the implant is the better choice. The reason: it does not interfere with the healthy neighbouring teeth and lasts decades longer.
A bridge only makes sense if:
- The neighbouring teeth are already damaged and will need to be crowned anyway
- You have contraindications for an implant (severe osteoporosis, bisphosphonates, acute bone loss)
- You have a strict short-term financial limit (although in the long run an implant is often cheaper)
What is a dental bridge?
A dental bridge is a prosthetic solution in which the missing tooth is replaced by an artificial tooth that hangs between two neighbouring teeth. The neighbouring (abutment) teeth must be ground down, and a crown is fixed onto them that holds the artificial tooth in the middle.
Types of bridges:
- Classic bridge — the most common (3 teeth: 2 abutments + 1 missing)
- Maryland bridge — bonded, without grinding (only for the front teeth)
- Cantilever bridge — with an abutment on one side only (less common)
- Implant-supported bridge — a combination of both (implants as abutments)
What is a dental implant?
A dental implant is an artificial tooth root made of titanium that is surgically inserted into the jawbone. After 3–6 months of osseointegration we place a crown on it that replaces the missing tooth.
The key difference from a bridge: the neighbouring teeth remain untouched. Each implant is independent — similar to a natural tooth.
Comparison: implant vs. bridge
| Criterion | Dental implant | Bridge | |----------|--------------|----------| | Price (1 tooth) | 900–1.040 € (implant + crown) | 800–1.200 € (3 crowns) | | Lifespan | 20+ years | 10–15 years | | Effect on neighbouring teeth | NONE — the teeth remain untouched | Grinding of 2 neighbouring teeth (irreversible) | | Hygiene | As with a natural tooth | Harder to clean (dental floss, special brushes) | | Feel | Like a natural tooth | Approximately natural | | Bone loss | NONE (the implant preserves the bone) | Gradual bone loss under the bridge | | Procedure | 1 procedure + 3–6 months of integration | 2 visits over 1–2 weeks | | Anaesthesia | Local (surgical procedure) | Local (grinding of teeth) | | Risk to neighbouring teeth | None whatsoever | Due to grinding: higher risk of caries, inflammation | | Long-term costs | ~50 €/year (1 tooth) | ~80–120 €/year (1 tooth, incl. replacements) |
1. You keep your healthy teeth
With a bridge, 2 neighbouring teeth must be ground down to become abutments. Even if they are completely healthy. This means:
- Permanent reduction of tooth substance (irreversible)
- Increased risk of caries under the crown
- Increased risk of root canal inflammation (3–12 % of teeth need endodontic treatment after grinding)
With an implant we do NOT touch the neighbouring teeth — they remain untouched.
2. You preserve the jawbone
A natural tooth with its root stimulates the bone and preserves it. Without a root (e.g. with a bridge) the bone gradually disappears — up to 25 % of its volume in 5–10 years.
An implant acts as an artificial root and stimulates the bone. Without bone loss.
3. Longer lifespan
Implants last 20+ years, many 30+ years. Bridges typically last 10–15 years, after which a replacement is needed (with further grinding of the teeth).
The difference in long-term cost: over 30 years of use you will replace the bridge 2–3 times. The implant once.
4. A natural feel
After integration, the implant behaves like a natural tooth — you can bite apples, nuts and meats. The bridge is also fairly natural, but not as perfect as an implant.
5. Easier hygiene
You clean the implant like a natural tooth (brush + dental floss). The bridge requires a special technique (dental floss under the pontic, special brushes) — which is why caries under the crown is more common with a bridge.
When is a bridge nonetheless a sensible choice?
Brutally honest: in specific cases.
1. The neighbouring teeth are already damaged
If the two neighbouring teeth already have large fillings or crowns (prepared for restoration), a bridge is more logical — you can add the missing middle tooth onto already-ground teeth without additional damage.
2. Contraindications for an implant
For patients who cannot have an implant:
- Bisphosphonates (osteoporosis medication) — risk of osteonecrosis
- Uncontrolled diabetes
- Active oncological therapy
- Severe bone loss where bone augmentation is not possible
3. An acute financial constraint
In the short term a bridge is cheaper (a single visit, without waiting for osseointegration). If you cannot afford 1.000 € right now, you can get a bridge for 800 €. In the long run, however, you will pay more (replacements, repairs).
4. A very elderly patient with various problems
For a very elderly patient (85+) with several health problems, a bridge means a faster solution without 3–6 months of integration. Quality of life matters more than a theoretical 20-year horizon.
Implant (1 tooth)
- Implant (Sweden & Martina): 650 €
- Crown (porcelain/zirconia): 250–390 €
- Total: 900–1.040 €
Classic bridge (3 teeth)
- 2 neighbouring crowns: 500–700 €
- 1 middle unit (artificial tooth): 300–500 €
- Total: 800–1.200 €
The price is almost the same. What differs: the long-term costs.
Long-term costs — a 30-year comparison
| Year | Implant | Bridge | |------|--------|----------| | Year 0 (initial cost) | 1.000 € | 1.000 € | | Year 10 | 0 € (the implant holds) | 0–80 € (repairs) | | Year 12 | 0 € | 1.200 € (replacement) | | Year 20 | 0–300 € (possible crown replacement) | 0 € | | Year 25 | 0 € | 1.200 € (second replacement) | | Year 30 | 0 € | 500 € (repairs) | | TOTAL (30 years) | 1.000–1.300 € | 3.900–4.000 € |
Over 30 years the implant is 3× cheaper than the bridge — if it integrates successfully (95–98 % success rate).
Effect on the neighbouring teeth — the most important difference
A bridge requires the irreversible grinding of 2 healthy teeth. Even if the teeth are completely healthy.
Consequences of grinding:
- Permanent loss of tooth substance (does not grow back)
- Fitting a crown = an endangered tooth nerve (3–12 % need endodontic treatment)
- Increased risk of caries under the crown (difficult cleaning)
- After 10–15 years: replacement = grinding again
With an implant the neighbouring teeth remain untouched. Even after 30 years.
Implant
- Cleaning like a natural tooth (brush 2×/day, dental floss)
- Annual check-up
- Professional cleaning 1–2×/year
Bridge
- Special dental floss (Superfloss or threading floss) to clean under the middle unit
- Special interdental brushes
- More frequent caries at the abutments due to difficult access
- More frequent professional cleaning (3–4×/year)
Patient experiences
"15 years ago I got a bridge over 3 teeth. After just 10 years one abutment tooth needed endodontic treatment, the other a caries repair. This year the bridge had to be replaced — grinding again. This time I chose an implant in a new location. I regret not doing it the first time." — Patient (54 years old)
"I wondered whether it was worth paying 1.000 € for one implant instead of 800 € for a bridge. When Dr Koderman explained the long-term calculation and the effect on the healthy neighbouring teeth, the decision was clear. After 7 years I am satisfied — not once has there been a problem." — Patient (41 years old)
Frequently asked questions
Can I keep the neighbouring teeth if I choose a bridge?
Not with a classic bridge. The Maryland bridge (bonded) is an exception, but it is only suitable for the front teeth and is less durable.
Will it hurt more with an implant than with a bridge?
The implant is a surgical procedure (30 min under anaesthetic), the bridge is grinding of the teeth (45 min under anaesthetic). Both under local anaesthetic, both practically painless. The implant causes mild swelling for 2–3 days after the procedure.
What if my implant does not integrate?
The success rate is 95–98 %. If it does not integrate within 3–6 months, we insert a new one free of charge. This is a rarity.
What is the price if I choose 3 implants instead of a three-unit bridge?
3 implants + 3 crowns = 2.700–3.120 €. That is an independent implant at each site where a tooth is missing. More than a three-unit bridge (~1.000–1.200 €), but the comparison is NOT fair — with 3 missing teeth you have 3 problems, not one.
Can I later replace a bridge with an implant?
Yes, but: the neighbouring teeth are already ground down. If they are in poor condition, you may need an additional procedure. It is better to choose an implant from the start.
What if I lose four teeth in a row — a bridge or several implants?
Here All-on-4 or several individual implants is a better choice than a long bridge.
