All-on-X vs Dentures: Which Is Right for You?
Dr. Nav Atwal
All-on-X is a fixed set of teeth anchored to dental implants, while dentures are removable and rest on the gums. All-on-X stays put, preserves jawbone, restores far more chewing power, and on the upper jaw leaves the palate uncovered — but it costs more upfront and requires surgery. Dentures are cheaper and non-surgical but can slip, allow continued bone loss, and limit what you can eat. For most people seeking stability and a long-term result, All-on-X is the more functional choice.
Key Takeaways
- All-on-X is fixed to implants; dentures are removable and rest on the gums. - All-on-X preserves jawbone, while conventional dentures allow bone loss to continue over time. - All-on-X restores far more chewing power and doesn't slip or need adhesive. - Upper All-on-X leaves the palate uncovered, so taste and comfort are better than a full denture. - Dentures cost less upfront and need no surgery; All-on-X costs more but is a fixed, long-term solution.
All-on-X and dentures both replace a full arch of missing teeth, but they do it in fundamentally different ways. Dentures rest on the gums and come out; All-on-X is fixed to dental implants and stays in. That single difference cascades into everything that matters day to day — how securely you can eat, how the treatment affects your jaw, and how the result feels over the years.
Stability and Fit
A conventional denture relies on suction and the shape of the gums to stay in place, and over time it can loosen, shift, or click during eating and speaking. All-on-X is anchored to implants, so it doesn't move, doesn't need adhesive, and lets you bite and laugh without a second thought.
Jawbone Health
This is one of the most important distinctions. When teeth are lost, the jawbone beneath begins to resorb, and a denture resting on the surface does nothing to stop it — which is why long-term denture wearers often develop a sunken facial appearance. Implants transmit chewing forces into the bone, helping to preserve it and maintain facial structure.
Chewing and Diet
Dentures restore only a fraction of natural biting force, and many foods become difficult or off-limits. Because All-on-X is implant-anchored, it restores a far greater share of chewing power, returning most foods to the menu.
Comfort and Taste
A full upper denture typically covers the palate, which can dull the sense of taste and feel bulky. An upper All-on-X bridge leaves the palate uncovered, so food tastes as it should and the mouth feels less crowded.
Maintenance
Dentures are removed daily for cleaning and need periodic relining or replacement as the gums change shape. All-on-X is cleaned in place like natural teeth, with professional removal and cleaning at maintenance visits.
Cost
Dentures are less expensive upfront and require no surgery, which makes them accessible. All-on-X is a larger initial investment but offers a fixed, durable, long-term result — and avoids the ongoing costs of relines and replacements.
Which Is Right for You?
Dentures can be the right answer where surgery isn't suitable or budget is the priority. But for most people who want stability, preserved bone, natural chewing, and a result they don't have to think about, All-on-X is the more complete solution. Many denture wearers also choose to convert to an implant-supported option later.
The best way to decide is an assessment of your bone, your health, and your goals together. In my practice, I walk patients through both paths honestly so the choice fits the person, not just the procedure.

Frequently Asked Questions
Is All-on-X better than dentures? For most people seeking stability, preserved bone, and natural chewing, All-on-X is more functional because it is fixed to implants. Dentures remain a valid option where surgery is unsuitable or budget is the priority. Do dentures cause bone loss? Yes. A denture rests on the gums and does not stimulate the jawbone, so bone resorption continues, which can lead to a sunken facial appearance over time. Implants help preserve the bone. Does All-on-X feel more natural than dentures? Generally yes. Because it is anchored to implants rather than resting on the gums, All-on-X is stable, doesn't need adhesive, and feels closer to natural teeth. Are dentures cheaper than All-on-X? Yes. Dentures cost less upfront and require no surgery, while All-on-X is a larger initial investment that provides a fixed, longer-term result. Can you convert dentures to All-on-X? In many cases yes. Existing denture wearers can often move to an implant-supported or fixed full-arch solution, subject to a clinical assessment of bone and health. Does upper All-on-X cover the roof of your mouth? No. Unlike a full upper denture, an upper All-on-X bridge leaves the palate uncovered, which improves taste and comfort.
