Almost every week someone sits down in my chair having already been told, elsewhere, that they "need an implant". Sometimes that's right. Often the honest answer is that they have two reasonable options and nobody has explained the trade-off in plain terms. So here it is.
The difference in one paragraph
A bridge replaces the visible part of a missing tooth by crowning the teeth either side and suspending a false tooth between them. An implant replaces the root: a titanium post goes into the jawbone, bone grows onto it over three or four months, and a crown is screwed on top. Bridges involve your neighbouring teeth. Implants don't.
Why the root matters more than people expect
Jawbone maintains itself because a root pushes on it every time you chew. Remove the root and the bone in that spot slowly resorbs — noticeably within a year, significantly within five. That's why a denture that fitted perfectly in 2019 rocks today, and why a gap that's been empty for a decade often needs grafting before an implant can go in.
A bridge does nothing to stop that. The gum under the false tooth hollows out over time, which is usually what patients notice first: a dark shadow at the gumline that no amount of brushing fixes.
If you're choosing between them and the teeth either side of the gap are healthy, I'll almost always steer you toward the implant. Not because it's the bigger fee — because I don't want to drill two good teeth to fix one missing one.
The two cases where I recommend a bridge
First: when the neighbouring teeth already need crowns. If both are heavily filled or cracked, a bridge treats three problems with one piece of dentistry. Doing an implant plus two separate crowns costs considerably more for a similar outcome.
Second: when time or health rules out surgery. A bridge is finished in two visits over three weeks. An implant is four visits over three to four months, and uncontrolled diabetes, current smoking or certain bone medications genuinely raise the failure risk. A bridge that works beats an implant that fails.
What each actually costs here
Triangle-area pricing varies because quotes bundle different things. Ours, itemised:
- Single implant, abutment and porcelain crown: quoted at consult
- Bone graft, if the scan shows it's needed: quoted separately
- Three-unit porcelain bridge: quoted at consult
The sticker gap is smaller than most people assume — and it closes further over time, because a bridge typically needs replacing after 10 to 15 years while a well-maintained implant often doesn't. Many PPO plans cover a share of either, and a plan can be staged across a December–January boundary to use two annual maximums.
How to decide in one appointment
Bring the question, not a decision. A cone-beam scan takes ten seconds and answers most of it: how much bone you have, where the nerve sits, and what condition the neighbouring teeth are really in below the surface. From there you get both options written down with prices and your insurance benefit applied, and you go home and think about it.
If anyone quotes you an implant without scanning first, get a second opinion.
Three questions patients ask right after this
Not always. It's better for bone preservation and it doesn't involve the neighbouring teeth — but if those teeth already need crowns, a bridge does two jobs at once and costs less overall.
We quote both at the consultation, itemised. The gap is usually smaller than people expect, and it narrows further once you account for a bridge typically needing replacement after 10–15 years.
Usually yes, but the bone under the gap will have thinned in the meantime, so grafting becomes more likely. If you're leaning implant eventually, doing it first is cheaper.
