All-on-4 vs. Traditional Dentures: Which Is Right for You?

If you’re missing all or most of your teeth, two of the most common solutions are traditional dentures and All-on-4 dental implants. Both replace a full arch of teeth—but the similarities largely end there. Here’s an honest, detailed comparison to help you make the right choice for your situation.

What Are Traditional Dentures?

Traditional dentures are removable prosthetics made of acrylic (plastic) teeth set in a gum-colored base. They rest on the gums and rely on suction and sometimes adhesive paste to stay in place. Upper dentures cover the palate; lower dentures are notoriously less stable.

What Is All-on-4?

All-on-4 is a dental implant system where four titanium implants are strategically placed in the jaw to support a full arch of fixed, permanent teeth. The prosthetic teeth are screwed into the implants—they don’t come out. You eat, speak, and smile with complete confidence, just like natural teeth.

Head-to-Head Comparison

Stability and Function

Dentures: Rest on gums and shift during eating and speaking. The lower denture is particularly unstable—up to 40% of lower denture wearers report significant discomfort and instability. Most denture wearers must avoid hard, sticky, or crunchy foods permanently.

All-on-4: Fixed, immovable. Biting force is restored to nearly 100% of natural teeth. You can eat steak, corn on the cob, apples—anything. No adhesives, no slipping, no embarrassing moments.

Bone Loss

Dentures: Accelerate jawbone loss. Without tooth roots to stimulate the bone, the jawbone resorbs (shrinks) at an average rate of 25% in the first year alone. This causes the “sunken face” look associated with long-term denture wearers, and dentures must be relined or replaced as the jaw changes shape.

All-on-4: Prevents bone loss. The titanium implants act like natural tooth roots, stimulating the jawbone and preventing resorption. Your facial structure is preserved for life.

Taste and Sensation

Dentures: Upper dentures cover the palate, significantly reducing taste sensation. Many patients report food “doesn’t taste the same” with dentures.

All-on-4: No palate coverage. Full taste sensation is preserved. Food tastes exactly as it should.

Longevity

Dentures: Require replacement every 5–7 years as the jawbone changes shape. Adhesives, repair kits, and relining add ongoing costs throughout your life.

All-on-4: Titanium implants can last a lifetime. The prosthetic teeth typically last 15–20 years before needing replacement—far longer than any set of dentures.

Upfront Cost

Dentures: Lower initial cost—typically $1,000–$3,000 per arch.

All-on-4: Higher upfront cost—typically $20,000–$30,000 per arch at 5D Smiles. However, financing from $149/month makes All-on-4 accessible for most patients.

Long-Term Cost

Over 20 years, dentures often cost MORE than All-on-4 when you factor in multiple replacements, adhesives, relining, and repairs. And that doesn’t account for the cost of bone loss—which may eventually require bone grafting or make future implants impossible.

Who Should Choose Dentures?

Traditional dentures may be the right choice if: upfront cost is the primary concern and financing isn’t an option, health conditions prevent surgery, or bone loss is too severe even for All-on-4 (though bone grafting can often address this).

Who Should Choose All-on-4?

All-on-4 is the right choice for most people who want: a permanent, natural-feeling solution; the ability to eat any food; prevention of bone loss and facial aging; and freedom from denture maintenance and embarrassment.
