Fixed teeth vs dentures: is it worth it?
A full arch of fixed teeth on implants is the closest thing to having your own teeth back. It's also the biggest step. Here's an honest look at both sides.
Medically reviewed by Dt. Hüseyin Yavuz Özbek, implant surgeon · Updated October 2026Fixed teeth are a full arch of teeth screwed onto four to six implants in the jaw. They stay in all the time and feel closest to natural teeth for eating and confidence. Compared with dentures, they need more surgery, more bone, more careful cleaning and a bigger budget, and they're usually only available privately in the UK.
What "fixed teeth" means
Instead of a denture resting on your gums, a full arch of teeth is screwed onto four to six implants placed in the jawbone. The NHS describes implants as a fixed alternative to removable dentures. You don't take the teeth out at night or to clean them.
The three options compared
| Dentures | Clip-on dentures | Fixed teeth | |
|---|---|---|---|
| Implants per jaw | None | 2–4 | 4–6 |
| Comes out? | Yes | Yes, for cleaning | No |
| Covers palate? | Upper: usually | Sometimes less | No |
| Bone needed | None | Some | More |
| Cleaning | Out of the mouth | Out of the mouth, plus implants | In the mouth, under the bridge |
| Cost | Lowest | Middle | Highest |
The real advantages
- Nothing moves. No slipping, clicking or adhesive.
- Eating feels closest to natural teeth.
- No plate over the roof of your mouth, which many people find improves taste and comfort.
- Confidence when talking, laughing and eating with others.
The honest downsides
- More surgery. Several implants per jaw, sometimes with extractions or a bone graft.
- Healing time. The Oral Health Foundation says implants usually take around four months to heal and bond with the bone.
- Cleaning takes care. Food can collect under the bridge. You'll need special brushes or a water flosser, and regular hygiene visits.
- Cost. The most expensive option, and the NHS says implants are usually only available privately.
- Repairs. The teeth on top can chip or wear and may need repairing over the years. There's no lifetime guarantee.
Who fixed teeth suit
Fixed teeth are often considered by people who:
- really don't want teeth that come out
- have enough bone, or are willing to have a graft
- are in good general health
- can commit to careful daily cleaning and check-ups
If that doesn't sound like you, a clip-on denture may give you most of the security for less.
Thinking about treatment abroad?
Many UK patients look at fixed teeth abroad because of the cost. If you do, check the dentist, the implant brand, the guarantee and the aftercare carefully. Our sister guide, published by the same clinic, covers this in detail: All-on-4 and All-on-6 explained.

Common questions
How many implants do fixed teeth need?
Usually four to six per jaw. Treatments using four implants are often called All-on-4®, which is a trademark of Nobel Biocare. The right number depends on your bone.
Will I be without teeth during treatment?
With good planning, you shouldn't have to go out without teeth. A temporary denture or temporary fixed teeth are usually provided while the implants heal.
Can fixed teeth be taken out?
Not by you. They're screwed onto the implants and only your dentist can remove them, for example for a check-up or repair.
Is it worth it if I'm in my 70s?
Age alone is rarely the deciding factor. Your general health, bone, and how much your current teeth or denture affect daily life matter more. A clip-on denture can be a gentler alternative.
