A missing tooth: implant, bridge, denture — or nothing?

When a tooth comes out — particularly a back one nobody sees — the obvious question is whether it needs replacing at all. It is a fair question, and the answer is not always yes.

What happens to the gap

Teeth are held in position by the ones around them. Remove one and the neighbours begin to tilt into the space, while the tooth opposite it gradually over-erupts because nothing is meeting it. Both processes are slow, neither is dramatic, and together they make the gap progressively harder and more expensive to restore later.

The bone that held the root also shrinks once the root is gone. That matters most if you might want an implant one day — the longer the gap is left, the more likely a graft becomes necessary first.

Bridge

A bridge replaces the missing tooth by anchoring to the teeth either side. It is fixed, comfortable, and quicker than an implant. The cost is that the neighbouring teeth have to be prepared — reduced in size — which is a significant thing to do to a healthy tooth. If those teeth are already heavily filled or crowned, that objection largely disappears and a bridge makes good sense.

Implant

An implant replaces the root itself and leaves the neighbouring teeth untouched, which is its main advantage. It takes longer, costs more up front, and depends on adequate bone and healthy gums. It is not suitable for everybody, and any clinic that presents it as automatically the right answer is not assessing your case.

Denture

A removable partial denture is the least expensive option and can replace several teeth at once. It is removable, which some people never get used to, and it needs adjustment over time as the mouth changes. For multiple missing teeth, or as an interim while bone heals, it is a sensible and honest choice.

And sometimes, nothing

If the missing tooth is the very last one in the arch and the bite is stable, leaving it can be reasonable. That is a judgement made by looking at your bite, not a general rule — and it should be reviewed, not forgotten.

How to have the conversation

Ask what each option involves, what it costs, how long it should last, what happens if it fails, and what the consequence of waiting a year would be. A straight answer to all five is the sign of a practice worth staying with.
