Losing a tooth raises a practical question fairly quickly: what, if anything, goes in the gap? Bridge or denture for a missing tooth is the choice most patients face, and neither is universally better. They suit different mouths, and the right answer depends on the teeth you still have as much as the one you have lost.

The essential difference
A bridge is fixed. The replacement tooth is attached to crowns or a wing bonded to the neighbouring teeth, and the whole thing is cemented permanently in place. It does not come out.
A denture is removable. A partial denture clips gently around your remaining teeth and is taken out for cleaning and overnight.
Everything else follows from that single distinction.
When a bridge suits better
- You want something fixed. Many people simply do not want anything removable, and that is a perfectly valid preference.
- The gap is small, typically one tooth, sometimes two.
- The neighbouring teeth are suitable anchors, either strong enough to carry crowns or, for an adhesive bridge, sound enough to bond to.
- Those neighbours would benefit from crowns anyway, perhaps because they are heavily filled.
- It is a front tooth. An adhesive bridge, which uses a discreet wing bonded behind the neighbouring tooth with little or no drilling, is often ideal here.
When a denture suits better
- Several teeth are missing, particularly if they are spread around the mouth.
- The gap is large, which is beyond what a bridge can reliably span.
- The neighbouring teeth are healthy and untouched. A partial denture usually needs no drilling of them at all, which is the more conservative choice.
- The neighbouring teeth are not strong enough to support a bridge.
- Cost matters. Dentures are generally the more economical way to replace several teeth.
- You may lose more teeth later. Teeth can usually be added to an existing denture, which a bridge cannot accommodate.
The honest comparison
Bridges: fixed and stable, nothing to remove, no plate covering the palate, and they feel closest to a natural tooth. Against that, the supporting teeth usually need reshaping for crowns, cleaning underneath requires a specific technique, and if a supporting tooth develops a problem the whole bridge is affected.
Partial dentures: conservative of the neighbouring teeth, capable of replacing several teeth at once, easily added to, and generally cheaper. Against that, they are removable, take some getting used to, and clasps may be visible depending on the design.
Our pages on dental bridges and dentures cover each in full, and our post on cleaning under a bridge explains the technique involved.
Could you just leave the gap?
Sometimes, honestly, yes. For a back tooth that does not show and is not affecting your chewing, leaving the space can be perfectly reasonable, and I would rather tell you that than fill a gap for the sake of it.
The caveat is what happens over time. Neighbouring teeth can tilt into an empty space, and the opposing tooth can over-erupt into it, which unbalances the bite and makes future treatment more complicated. Whether that matters in your case depends on which tooth and where.
It is worth having the conversation rather than defaulting either way.
Timing after an extraction
Gums and bone reshape considerably in the months after a tooth is removed, which is why permanent replacements are usually planned rather than rushed. Our post on healing after tooth extraction sets out the timeline.
Where several teeth are removed at once, an immediate denture can be fitted on the same day so you are never without teeth, with adjustments made as healing progresses. That is a genuinely useful option and worth asking about before an extraction rather than after.
How the decision gets made
At your appointment, the gap and the teeth around it are examined, usually with an X-ray to assess the roots and bone of any potential supporting teeth. Your gum health matters too, since neither option works well on unhealthy foundations.
Then you get the options laid out plainly, with the advantages, the trade-offs and written costs for each. The decision is genuinely yours; my job is making sure you have the full picture rather than steering you.

In summary
A bridge is fixed and feels most like a natural tooth, but asks something of the neighbouring teeth. A denture is removable, conservative and more economical, and suits larger or multiple gaps. Neither is better in the abstract; the teeth around the gap decide.
