When patients lose multiple teeth — or face losing them — they're often presented with two options: dentures or dental implants. Both replace missing teeth. But they work very differently, and their long-term outcomes are not equivalent. Here's an honest comparison from a periodontist who places dental implants every day.
The Fundamental Difference
The most important distinction between implants and dentures is what they do — or don't do — for your jawbone.
Your jawbone is maintained by the stimulation of tooth roots pressing against it during chewing. When a tooth is lost, the bone beneath it no longer receives that stimulation. The body interprets this as a signal to resorb the bone — and it begins doing so within weeks of extraction. Over the first year after tooth loss, up to 25% of bone volume can be lost. This accelerates over time.
Dentures sit on top of the gum and bone — they do not replace the tooth root and provide no stimulation. The bone loss continues underneath them, which is why dentures that fit well initially often become loose over the years. Dental implants, by contrast, are placed directly into the jawbone and fuse with it through a process called osseointegration. They function as tooth roots, preventing bone loss entirely.
Comfort and Function
Dentures are removable prosthetics that rest on the gums. Lower dentures in particular are notoriously unstable, because the lower arch has less surface area to grip. Many patients find that lower dentures rock, shift, and limit their diet significantly. Adhesives help temporarily but don't solve the underlying instability. As bone continues to resorb, fit deteriorates further.
Implants are fixed in the jaw and function like natural teeth. Patients bite, chew, and speak without thinking about their teeth — because the implants behave exactly as roots do. There is no movement, no adhesive, no dietary restriction, and no removal at night. Most patients report that implants are indistinguishable from their natural teeth in everyday function.
Cost: The Real Comparison
Dentures have a lower upfront cost, which makes them attractive. But cost comparisons should account for the full picture:
- Dentures require relining as bone resorbs and the fit changes — typically every few years
- Poorly fitting dentures accelerate bone loss, potentially requiring more complex (and more expensive) bone grafting if implants are pursued later
- The longer a patient waits to pursue implants after tooth loss, the more bone is gone — meaning more extensive (and more costly) pre-implant bone grafting may be needed
- Implants, maintained well, last decades. The per-year cost over a lifetime is often lower than repeatedly replacing dentures
We understand that implants are a significant investment upfront, and we work with several financing partners to make treatment accessible. But patients should make this decision with full information — not just the initial sticker price.
Implant-Supported Dentures: The Middle Ground
For patients who want the stability of implants but at a lower cost than replacing every tooth individually, implant-supported overdentures offer a compelling option. Two to four implants are placed in the jaw, and the denture "snaps on" to them. The result is dramatically better stability than a conventional denture — and the implants prevent the bone loss that makes conventional dentures problematic over time.
For patients who are missing all their teeth, All-On-4 or All-On-6 full-arch implants provide a completely fixed bridge anchored to four or six implants. The result is a full set of teeth that do not come out — permanent, stable, and bone-preserving.
Who Is a Candidate for Implants?
Most healthy adults who have lost teeth are candidates for dental implants. The key requirements are:
- Sufficient jawbone volume to anchor the implant (if not, bone grafting can often create it)
- Healthy gums free of active infection
- No uncontrolled systemic conditions that would impair healing
Even patients who have been told they "don't have enough bone" for implants are often candidates after a bone grafting procedure. A 3D CBCT scan gives us the precise information needed to evaluate what's possible for each patient specifically.
Our Recommendation
For most patients, dental implants are the superior long-term solution. They preserve bone, function like natural teeth, and eliminate the ongoing complications of removable dentures. The question isn't really "implants or dentures" — it's "what type of implant solution is right for your situation and budget?" We're happy to walk through all the options at a consultation.
