An implant replaces the root of a missing tooth and leaves the teeth either side untouched. A bridge is faster and costs less up front, but it requires grinding down the two neighbouring teeth to carry the false one. The condition of those two teeth decides the answer more than anything else.
The one question that settles most cases
Look at the teeth on either side of your gap.
Are they healthy, untouched, with no large fillings? Then a bridge means taking two perfectly good teeth and cutting them down to stumps, permanently, in order to avoid one operation. That is a poor trade, and an implant is almost always the better answer.
Do they already have large fillings or crowns, or do they need them? Then the calculation flips. You were going to be crowning those teeth anyway. Carrying a false tooth between them costs you very little extra damage — and a bridge becomes the sensible, cheaper, faster answer with no shame attached.
That is genuinely most of it. The rest is detail.
What each one actually costs
NEEDS SIGN-OFF C-05, C-11, C-12 Costs stated here — three-unit bridge $3,500–$6,000; single implant, post+abutment+crown $4,000–$6,500; bone graft $500–$1,200. Approve as written, or give the correction.
Implant: $4,000 to $6,500 in this area for the post, abutment and crown together. A bone graft, if needed, adds $500 to $1,200.
Three-unit bridge: $3,500 to $6,000.
The gap is narrower than people expect, and it closes further when you notice that most dental plans contribute meaningfully toward a bridge and cover implants poorly or not at all. For an insured patient, a bridge is frequently the cheaper option out of pocket even when the sticker prices are similar.
Time
Bridge: two or three appointments over two to four weeks. You are finished inside a month.
Implant: three to six months, most of it waiting while bone fuses to titanium. Longer if a graft is needed first. You are not left with a visible gap in the meantime, but you are living with a temporary.
If you need the tooth for a specific date, say so. It changes the advice.
The bone
This is the argument for implants that nobody explains properly, so here it is.
The bone in your jaw is maintained by the force of chewing, transmitted down through the root of the tooth. Take the root away and the bone stops being loaded, and it thins. Fastest in the first year, then more slowly, but it does not stop.
An implant replaces the root. Force goes back into the bone, and the bone stays.
A bridge does not. It spans the gap. The bone underneath is unloaded and continues to shrink — which is why, ten years on, you can often see a hollow under a bridge where the gum has receded away from the false tooth. It is also why a bridge tends to look worse with age while an implant does not.
How each one fails
Both fail eventually. They fail differently, and this matters.
An implant fails when the bone around it is lost — peri-implantitis, caused by the same bacteria that destroy bone around natural teeth. It cannot decay. Your cleaning schedule matters more after an implant, not less.
A bridge fails when one of the two supporting teeth develops decay at the margin, or fractures under the extra load it is now carrying. And here is the sting: when a bridge fails, it often takes a supporting tooth with it. You started with one missing tooth. Now you have two, and a much bigger problem.
That asymmetry is worth sitting with. An implant that fails costs you the implant. A bridge that fails can cost you a tooth you still had.
When the honest answer is neither
Leaving the gap is a real option and we will not pretend otherwise — particularly for a back molar nobody sees, with nothing above it to drift down.
What you should know is what follows: the opposing tooth erupts into the empty space, the teeth either side tilt in, your bite changes, food packs into the new angles, and the bone thins. None of it happens next week. All of it happens.
The gap is cheapest to close on the day the tooth comes out. If money is the obstacle — and it very often is — ask about a bone graft at the time of extraction. A few hundred dollars now can save you a much larger graft in three years.
Questions people ask
Can I have an implant if the tooth came out years ago?
Usually, but the bone has been shrinking since the day it left, so a graft is more likely. The longer the wait, the more likely the graft — which is one of the more unfortunate ironies in dentistry.
Does a bridge feel different to a real tooth?
Slightly. You cannot floss between the units in the normal way; you thread underneath with a floss threader or a water flosser, every day, without exception. That daily habit is what decides whether the bridge lasts ten years or five.
Which lasts longer?
An implant, usually. Implants have around a 95% survival rate at ten years; bridges typically run ten to fifteen years before needing replacement.
Can I switch from a bridge to an implant later?
NEEDS SIGN-OFF K-01 Claims about the practice — Implants PLACED AND RESTORED in-house. Approve as written, or give the correction.
Yes, but you will have lost bone under the bridge in the meantime, and the supporting teeth have already been cut down. Going bridge-first is not a free option to try.
