Implant vs. Dental Bridge
An implant replaces a missing tooth independently, anchored in bone; a bridge replaces it by attaching to and relying on the two neighboring teeth, which usually need to be reduced and crowned to support it.
| Factor | Implant | Bridge |
|---|---|---|
| Effect on neighboring teeth | None — neighboring teeth are untouched | Adjacent teeth are reshaped and crowned to anchor the bridge |
| Bone preservation | Maintains bone at the site through chewing stimulation | Does not stimulate bone; resorption continues underneath |
| Typical lifespan | Post can last decades; crown often 10-15 years | Typically 10-15 years before replacement needed |
| Treatment timeline | Several months, including healing | Often completed in two to three visits over a few weeks |
| Upfront cost | Generally higher per tooth | Generally lower upfront, but tied to long-term cost of the anchor teeth |
Effect on neighboring teeth

Bridge

Bone preservation
Implant

Bridge
Does not stimulate bone; resorption continues underneath
Typical lifespan
Implant
Post can last decades; crown often 10-15 years
Bridge
Typically 10-15 years before replacement needed
Treatment timeline
Implant

Bridge
Often completed in two to three visits over a few weeks
Upfront cost
Implant
Generally higher per tooth
Bridge
Generally lower upfront, but tied to long-term cost of the anchor teeth
Implant: strengths
- + Doesn't affect healthy neighboring teeth
- + Preserves jawbone over time
- + Generally the longer-lasting solution
Limitations
- − Requires adequate bone and a healing period
- − Higher upfront cost
- − Involves a minor surgical procedure
Bridge: strengths
- + Faster overall treatment timeline
- + No surgical procedure required
- + Lower upfront cost in many cases
Limitations
- − Requires reducing healthy adjacent teeth
- − Doesn't prevent bone loss at the missing-tooth site
- − If an anchor tooth fails, the whole bridge is affected
Questions to ask your dentist
- —What condition are my teeth on either side of the gap in, and would they need significant reduction for a bridge?
- —Given my bone levels, am I a straightforward implant candidate or would grafting be needed?
- —How do the long-term costs compare once I factor in likely future replacements?
Frequently asked questions
Is a dental implant always better than a bridge?+
Not universally — bridges remain a reasonable option when neighboring teeth already need crowns anyway, when a faster timeline is a priority, or when bone or budget make an implant impractical.
Does a bridge prevent the bone loss that happens after losing a tooth?+
No — a bridge doesn't transmit chewing stimulation into the jawbone the way a tooth root or implant does, so bone at the missing-tooth site continues to gradually resorb underneath it.
