Dental Implant vs Bridge vs Denture
How the three ways to replace a missing tooth compare on longevity, bone health, feel and cost.
Quick answer · What's the difference between a dental implant, a bridge, and a denture?
A dental implant is a titanium root plus a crown that replaces one tooth on its own, lasts 20+ years, and is the only option that preserves jawbone. A dental bridge is faster and fixed but requires grinding down the two neighboring teeth and lasts about 10–15 years. A denture is the least expensive and non-surgical but is removable, less stable when chewing, and does not stop bone loss. For a single missing tooth in a healthy patient, an implant is usually the longest-lasting choice; dentures suit many missing teeth on a tighter budget.
Side-by-side comparison
| Dental Implant | Bridge | Denture | |
|---|---|---|---|
| How it works | Titanium root + crown | Crown anchored to 2 neighbor teeth | Removable prosthetic |
| Neighboring teeth | Untouched | Ground down | Untouched |
| Preserves jawbone | Yes | No | No |
| Typical lifespan | 20+ years / lifetime | 10–15 years | 5–10 years |
| Feels like a real tooth | Closest | Fixed, natural | Least — can slip |
| Surgery needed | Yes | No | No |
| Typical cost | $4,500–$6,500 / tooth | $2,000–$5,000 | $1,000–$3,000 / arch |
| Best for | One or few teeth, long-term | Gap between healthy teeth, faster | Many teeth, lower budget |
Frequently Asked Questions
Is a dental implant better than a bridge?
For a single missing tooth in a healthy patient, an implant is usually the better long-term choice: it lasts 20+ years, preserves bone, and leaves the neighboring teeth untouched, whereas a bridge grinds down two healthy teeth and lasts about 10–15 years. A bridge can still be the right call when the neighbors already need crowns or when surgery must be avoided.
Which is cheapest: implant, bridge, or denture?
A denture is usually the least expensive up front ($1,000–$3,000 per arch), then a bridge ($2,000–$5,000), then an implant ($4,500–$6,500 per tooth). Over 20 years an implant is often the best value because it rarely needs replacing, while dentures and bridges are typically redone once or more.
Do dentures cause bone loss?
Yes. Removable dentures and traditional bridges sit on top of the gum and do not stimulate the jawbone, so the bone slowly resorbs over the years, which can change facial shape and loosen the denture. Dental implants are the only option that transmits chewing force into the bone and preserves it.
How much more does a dental implant cost than a bridge over 20 years?
Up front, a Bay Area implant runs $4,500–$6,500 versus $2,000–$5,000 for a three-unit bridge — a gap of roughly $1,500–$2,500. Over 20 years the gap usually closes or reverses: a bridge typically needs replacing once or twice at 10–15 year intervals, and if a ground-down anchor tooth later fails, it can turn one missing tooth into two. An implant placed once commonly lasts 20+ years with normal hygiene.
