One tooth is missing and you have been offered two ways to replace it. The difference is not really about the tooth being replaced — it is about what each option asks of the teeth on either side of the gap.
What is the difference, in one line?
An implant replaces the root. A titanium fixture is placed in the bone where the root used to be, and a crown is attached to it once the bone has healed around it. Nothing is attached to the neighbouring teeth.
A bridge does not replace the root. It spans the gap with a run of joined crowns, and the teeth on either side carry the load — they are, as the American Dental Association puts it, attached to surrounding teeth for support.
What a bridge asks of the neighbouring teeth
To carry a bridge, the teeth on both sides of the gap have to be reduced in size so that crowns will fit over them. That is irreversible. If those two teeth are currently healthy and untouched, a bridge means treating three teeth to replace one.
That single fact is what most of the decision rests on. It is also why the answer changes depending on the mouth rather than the procedure.
When a bridge is the more sensible choice
There are several situations where it clearly is.
If the neighbouring teeth already need crowns — they are heavily filled, cracked, or already crowned — then a bridge asks for nothing that was not already needed, and the objection above disappears.
If there is not enough bone to hold an implant and you would rather not have grafting, a bridge avoids that surgery. If a medical condition makes surgery inadvisable, the same applies.
And time matters for some people. A bridge is completed in a shorter overall period than an implant, because an implant needs a healing phase between placement and the final crown. For a patient who is in Korea for a limited stay, that difference can decide the plan — see our guide to planning dental treatment around a visit.
When an implant is usually preferred
Where the teeth on either side are healthy, an implant leaves them alone. That is its main argument, and it is a strong one.
An implant also transmits chewing force into the bone in a way a bridge does not, and bone that is loaded tends to be maintained. Where a tooth has been missing for a long time, however, some of that bone may already have been lost, which is why an assessment starts with a scan rather than a conversation about preferences.
What each costs here
Our fees are published in full on the fee schedule, and they are the same fees quoted to patients in Korea — there is no separate rate for international patients.
An implant is three parts: the fixture that goes into the bone, the abutment that sits on top of it, and the crown you chew with. Our implant fees cover all three. What separates the price levels is mainly the crown — the lowest level carries a porcelain-fused-to-metal crown, which is more prone to chipping, and the levels above it carry a zirconia crown. Bone grafting, where it is needed, is charged separately.
A bridge is priced by the crowns it is made of. A crown in porcelain-fused-to-metal is ₩400,000. In zirconia, a back tooth is ₩450,000. For a front tooth there are two options: ₩450,000, where the shade is chosen from a set of stock shades, and ₩550,000 for a built-up zirconia crown, where the shade is built to match the teeth on either side of it. We generally suggest the built-up crown at the front, because a stock shade sitting next to your own front teeth is easier to notice.
What your own case costs depends on what the examination finds, so treat the schedule as the starting point and your written estimate as the number that counts.
How long does each last?
Neither is a permanent object, and anyone who tells you a figure without looking in your mouth is guessing. What determines the answer is largely the same for both: the health of the gums, how heavily you bite, and whether the area is kept clean.
The failure modes differ, though. A bridge fails most often because decay or gum disease reaches one of the supporting teeth, and losing a support means losing the bridge. An implant does not decay, but the bone around it can be lost to infection, which is why implants need the same cleaning and the same regular checks as teeth.
Frequently asked questions
Does an implant hurt more than a bridge?
Implant placement is surgery and a bridge is not, so the recovery is different — some swelling and soreness for a few days is usual after placement. The procedure itself is done under local anaesthetic in both cases. Preparing teeth for a bridge is not painless either; it is simply shorter.
Can I have an implant if the tooth has been missing for years?
Often yes. Bone that is no longer being used tends to reduce over time, so the question is how much is left, and that is answered by a CT scan rather than by how long ago the tooth was lost. Where bone is insufficient, grafting alongside placement is a common route.
How many visits does each take?
A bridge is usually completed over a small number of visits within a few weeks. An implant is spread over a longer period because the bone needs time to heal around the fixture before the crown is fitted. Your own schedule is set at the planning appointment, and if you are travelling it is worth raising your dates at that point.
Can a bridge be changed to an implant later?
Yes, though it is worth understanding what carries over. The bridge can be removed and an implant placed in the gap, but the two neighbouring teeth have already been reduced and will still need crowns of their own. The reduction is not undone by changing plan later.
If you are weighing the two, bring the question to the consultation rather than deciding in advance. The scan usually settles it faster than a comparison does.
