Single implants vs full-arch (All-on-4)
A single implant ($3,000 – $6,500/tooth) is right for one or a few missing teeth. Once most of a jaw is failing, full-arch All-on-4 ($15,000 – $30,000/arch) usually becomes the better value, one fixed price for the whole arch.

Single vs full-arch, compared
| Factor | Single implant(s) | Full-arch (All-on-4 / All-on-6) |
|---|---|---|
| Best for | One or a few missing teeth with healthy neighbors | Most or all teeth in a jaw failing or missing |
| Implants placed | One implant per missing tooth | Four to six implants support a full fixed bridge |
| Typical cost | $3,000 – $6,500 per tooth | $15,000 – $30,000 per arch (All-on-4); All-on-6 $20,000 – $40,000 |
| When it stops adding up | Replacing many teeth one at a time gets expensive fast | One fixed price covers the whole arch regardless of teeth missing |
| Result | A single tooth that matches the others | A full set of fixed teeth on one jaw |

A single implant vs a full arch, visually
A single implant replaces one tooth with its own post, abutment, and crown. A full arch replaces a whole jaw with one fixed bridge on just four or six implants, that's why the math changes as you replace more teeth.
Which one wins for you
Single implants scale close to linearly, each missing tooth is another post, abutment, and crown. Full-arch pricing is fixed per arch no matter how many teeth are gone.
Single implants win when
You're missing one or a few teeth and the rest are healthy. Each tooth gets its own post, abutment, and crown, and you keep your natural teeth in play at a lower overall cost.
Full-arch wins when
Most or all of a jaw is failing. All-on-4 is one fixed per-arch price no matter how many teeth are gone, so it usually beats replacing teeth one at a time on both cost and simplicity.
The more teeth you're replacing in one jaw, the more full-arch tends to win on cost and simplicity. One or two teeth with healthy neighbors? Single implants cost less overall.

Single vs full-arch FAQ
At how many teeth does All-on-4 beat single implants?
There is no single magic number, but as you approach replacing most of a jaw, per-tooth implants add up quickly while All-on-4 is a fixed per-arch price. Many patients missing or losing most of an arch find full-arch is the better value. A provider can run the exact math for your mouth.
Is All-on-4 the same as a denture?
No. All-on-4 is a fixed bridge anchored to four implants that you do not remove, unlike a conventional removable denture. Implant-supported overdentures are a separate, removable option.
Can I do a few single implants instead of a full arch?
Sometimes, if enough of your own teeth are healthy. If most teeth in the arch are failing, replacing them individually is usually more expensive and complex than a full-arch solution. This is exactly the trade-off to review with a provider.
