When you lose one or more teeth, the first question is often this: a dental implant or a bridge? Both methods restore the missing tooth, but they work on completely different principles. A bridge leans on the neighbouring teeth; an implant stands on its own and replaces the root of the missing tooth. In this guide we compare the two options on jawbone preservation, impact on neighbouring teeth, lifespan, treatment time and cost, and explain when each one fits. The final choice is always made on the basis of an individual examination.
Why Restore a Missing Tooth?
A missing tooth is not just an aesthetic matter. Without chewing load, the jawbone at the empty site can gradually resorb; neighbouring teeth can tilt toward the gap, and the opposing tooth can over-erupt. This disturbs the bite and makes future treatment harder. That is why it is important to restore a missing tooth in good time — whether with a bridge or an implant.
What Is a Dental Bridge?
A dental bridge is a fixed prosthesis that rests on the teeth on either side of the gap. The healthy teeth next to the gap are ground down (reduced), and an artificial tooth (the pontic) is suspended between the supporting crowns placed over them. A bridge is made in a relatively short time, without surgery, and restores the appearance of the missing tooth. Its main drawback, however, is that it requires grinding down healthy neighbouring teeth, and the jawbone under the bridge is left without chewing load.
What Is a Dental Implant?
A dental implant is a titanium screw placed into the jawbone; it replaces the root of the missing tooth. After the titanium fuses with the bone (osseointegration), an abutment (support) and a custom-made crown are fitted onto the implant. The implant stands on its own without touching the neighbouring teeth, and transfers chewing load directly into the bone, helping it stay active.

| Criterion | Dental implant | Dental bridge |
|---|---|---|
| Neighbouring teeth | Untouched | Two adjacent teeth ground down |
| Jawbone | Chewing load preserves the bone | Bone can resorb under the bridge |
| Lifespan | Decades with proper care, often lifelong* | Usually 7–15 years* |
| Treatment time | Longer (osseointegration, months) | Shorter (weeks) |
| Surgery | A surgical procedure is required | No surgery |
| Hygiene | Cleaned like a natural tooth | Needs special cleaning under the bridge |
| Initial cost | Usually higher | Usually more affordable |
*Lifespan depends on individual hygiene, bone condition and materials. An accurate prognosis is given only after an examination.
When Might a Bridge Be Suitable?
In some situations a bridge is a sensible choice: when the teeth next to the gap already need crowns or large fillings anyway; when there is a health contraindication to surgery, or not enough bone for an implant and the patient declines bone grafting; or when a faster solution is needed. In these cases a bridge can reliably restore the function and appearance of the missing tooth. The decision is made after assessing the condition of the neighbouring teeth and the bone volume during the examination.
When Is an Implant Preferable?
An implant is preferable especially when the neighbouring teeth are healthy, because there is no need to grind them down. An implant also transfers load to the jawbone and helps prevent bone loss, and with proper care it can last a long time — often decades.
We compared the options for restoring a single tooth in more detail in our ‘Single tooth implant’ article. It should be noted that an implant requires a surgical procedure and a longer course of treatment.
What to Know About Cost and Timing
At the outset a bridge usually looks more affordable, while an implant requires a larger investment. Over the long term, however, the picture can change: a bridge may need replacing after some years, whereas an implant fixture, with proper care, lasts longer. The exact price depends on the system used, the materials and whether additional procedures (such as bone grafting) are needed, and is determined only after an examination. This article does not quote specific prices — a consultation is recommended for an individual estimate.
