From Dentures to Fixed Teeth: Your All-on-X Options Explained

Dentures rest on the gum, and the jawbone underneath naturally shrinks over years without a tooth root to stimulate it — which is why a well-fitting denture often loosens over time. All-on-4 or All-on-6 replace that denture with a fixed bridge anchored to implants, so it no longer moves, clicks or needs adhesive. Switching usually means a CT scan, sometimes a bone graft, and osseointegration (~3–6 months) before the final fixed teeth — but many patients get fixed temporary teeth on day one.

A natural tooth root constantly signals the jawbone underneath to stay strong; once teeth are gone, that signal disappears and the bone gradually resorbs, especially in the years after tooth loss. Because a denture only rests on top of the gum rather than replacing the root, it can't stop this process — which is why a denture that fit well at first often becomes loose, requires more adhesive, or starts rubbing sore spots as the years go on. This is a normal, well-documented part of ageing without tooth roots, not a sign you're doing anything wrong. Implants are the only replacement option that stimulates the bone in a similar way to a natural root, which is why they typically stop this ongoing shrinkage where they're placed.

Moving from a removable denture to an All-on-4 or All-on-6 fixed bridge changes daily life more than most patients expect. The new teeth are anchored to implants rather than resting on the gum, so they don't move when you eat, laugh or speak, and there's no adhesive, no soaking overnight, and no risk of a denture slipping in public. Chewing force improves substantially too, since implants transmit bite force to the bone far more effectively than a denture resting on soft tissue — many patients find foods they'd avoided for years become comfortable again. The trade-off is that fixed teeth involve implant surgery and a healing period, rather than simply being fitted and adjusted like a denture.

The process starts the same way as any implant assessment: a free review of your photos or X-ray, then a 3D CT scan on arrival to measure exactly how much bone remains under your current denture. If years of bone loss mean there isn't quite enough to place implants safely, a bone graft is planned first — this is common for long-term denture wearers and is factored into your timeline, not a surprise added later. Once your bone is confirmed suitable, All-on-4 or All-on-6 implants are placed under local anaesthetic, and a fixed temporary bridge is usually fitted the same day where implants are stable enough, so you're not left wearing your old denture during healing. The final custom bridge follows on a second, shorter trip once osseointegration is complete.

A conventional denture is cheaper upfront than implant-supported fixed teeth, but it needs periodic relining or remaking as your bone continues to change, and it never delivers the same stability. All-on-4 in Turkey typically costs £3,000–4,500 per arch, which is a larger one-time investment than a denture but is designed to be a long-term, fixed solution rather than something you keep adjusting. If a bone graft is needed first, that's usually quoted separately based on your CT scan. Rather than comparing sticker prices alone, ask for a written quote that covers your specific case — implants, any grafting, and the bridge — so you can weigh the real total against a lifetime of denture adjustments.
