Dental Implants vs Dentures in the UK: Which Is Right For You?

Dentures sit on top of the gum ridge and rely on suction, retention clasps to neighbouring teeth, or denture adhesive. Implants are surgically placed in the jawbone and fuse with bone through osseointegration. The resulting stability is dramatically different.

Implants preserve jawbone volume in the long run. Bone resorbs progressively under a denture because there is no stimulating chewing load transferred through the bone, which is why long-term denture wearers develop the characteristic sunken facial appearance. Implants transfer chewing load directly through the fixture and maintain bone volume.

A complete upper or lower denture costs around £600-£1,500 privately and is available on the NHS for around £319.10 at Band 3. A two-implant lower overdenture costs £4,800-£6,500. A full-arch fixed bridge on four implants costs £15,000-£22,000 per arch. The price difference reflects the difference in clinical outcome.

Over twenty years, dentures usually need replacement two to three times because the underlying ridge changes shape as bone resorbs. Implants last twenty years and beyond at survival rates around ninety per cent in well-maintained cases. The total-cost-of-ownership comparison narrows over time, though implants remain materially more expensive.

Dentures are still the right answer for some patients. Where medical history precludes implant surgery, where budget rules out implant work, or where dexterity for cleaning fixed restorations is limited, a well-made denture or an implant-retained overdenture is the better clinical choice than a fixed implant solution.
