Dentures rest on the gums and come out each day. Implants anchor replacement teeth in the jawbone, and All-on-4 holds a full arch of fixed teeth on four implants. The right one depends on how many teeth are missing, which jaw, and how much bone is left.
Five Ways to Replace Several Teeth
Someone missing several teeth is really choosing among five options, not two:
- A partial denture, a removable appliance that replaces some teeth and usually clasps onto the teeth you still have
- A complete denture, such as a set of digital dentures, which replaces every tooth in an arch, is designed from a 3D model of your mouth and rests on the gums
- An implant-held denture, often called a snap-in denture, which still comes out but clips onto two or more implants so it moves less
- An implant-supported bridge, where a few implants carry a row of replacement teeth that stays in
- A fixed full arch, where All-on-4 implants hold one bridge of replacement teeth on four implants in the jaw
The American Dental Association notes that implants can give an overdenture the same support that remaining natural teeth can.
Start With How Many Teeth Are Missing
- When a few teeth are missing and healthy teeth surround the gap, a partial denture or an implant-supported bridge usually makes more sense than replacing a whole arch. One missing tooth is a separate question.
- When most of the teeth in one jaw are missing, or the rest are failing, a complete denture, an implant-held denture and a fixed full arch are all real contenders.
The jaw matters too. A lower denture covers about half the area of an upper one and sits against the moving tongue, so it tends to be harder to keep in place, and most research on implant support has focused on the lower jaw.
On the fixed full-arch route, any natural teeth left in that jaw are removed, and that cannot be undone. If some of your own teeth are worth keeping, say so, because it changes which options make sense.
What Happens to the Jawbone
After teeth are lost, the bone that held them slowly shrinks. A denture rests on the gums and puts no load on that bone, so the ridge keeps narrowing and a denture that fit well at first can feel loose years later. A reline restores the fit but does not slow the shrinking. An implant sits in the bone and loads it, which helps preserve it. If the bone is too thin for implants, a graft can sometimes rebuild it first, adding time and cost.
What the Research Says About Satisfaction
Most of the evidence comparing implant support with ordinary dentures comes from people with no teeth in the lower jaw. A 2009 meta-analysis that reviewed seven randomized trials in that group found implant-retained overdentures were rated more satisfying than new conventional dentures, at a level the authors called clinically relevant. The authors also noted that results varied widely between studies, so the size of the benefit is still uncertain. Expert consensus statements from McGill University in 2002 and from York in 2009 recommended a two-implant overdenture as the first-choice standard of care for a toothless lower jaw.
These trials compared removable dentures with and without implants, not fixed arches, so they are a reason to ask about implant support rather than a ruling for any one mouth.
What Each Option Costs
Dentures generally cost less up front than implant-based options, and the price of an implant-held denture depends on how many implants it needs. We do not publish a denture price, so ask for an estimate after your exam.
For the implant routes, Redondo Beach Dental Group’s typical prices are $3,000 to $6,000 for a single implant including the abutment and crown, and $20,000 to $30,000 per arch for All-on-4. The single-implant price applies to each implant, which is why several missing teeth are usually treated with an implant-supported bridge or a full arch rather than one implant per tooth.
Compare what a quote includes, since extractions, bone grafting, a 3D scan and a temporary set of teeth can each be in or out. A denture also has later costs, because its fit changes and it can wear or crack.
Dental plans vary widely in how they treat dentures and implants, and annual maximums apply. We accept PPO plans, so ask us how your plan applies to the option you are weighing. For the balance, we offer payment plans through Cherry, CareCredit and LendingClub, plus an in-office plan for patients without insurance.
Daily Life: Cleaning and Sleeping
Removable options come out. A complete or implant-held denture is brushed daily with a soft brush and a denture cleaner, kept in water when it is out, and usually taken out at night so the gums can rest.
Fixed options stay in. Only the dental team takes a fixed arch off, and food collects under it, so it needs daily cleaning with a water flosser or a similar tool. Gum infection around an implant, called peri-implantitis, can cause bone loss, so cleaning and checkups matter for every implant route.
Who Tends to Suit Which
A denture is often the better fit when:
- You want to avoid surgery, or your health makes it a poor idea
- Budget is the main limit right now
- You are comfortable with a removable appliance and its daily care
An implant-held denture is often the better fit when:
- A denture slips, particularly in the lower jaw, and you want it to stay put
- You want more stability than a standard denture for less than a fixed arch, and do not mind taking it out to clean
A fixed option, an implant-supported bridge or All-on-4, is often the better fit when:
- You want teeth that stay in, and you are ready for surgery and months of healing
- Your gums and general health are well controlled, and you will keep up cleaning and checkups
Reasons an Implant Plan May Need to Wait
Active gum disease has to be treated before implants. Diabetes that is not well controlled slows healing, smoking raises the risk of an implant failing to bond, and past radiation to the jaw and certain bone medications need to be discussed. Age on its own is not a barrier.
Frequently Asked Questions
What is the difference between false teeth and dental implants?
False teeth, or dentures, are removable replacement teeth that rest on the gums, while dental implants are small posts placed in the jawbone to hold replacement teeth. Dentures need no surgery and cost less up front. Implants need surgery and several months of healing, and they put load on the bone the way natural roots do.
Can you eat normally with implants?
Most people with implant-supported teeth can eat a wide range of foods, and many find them steadier than a denture. Soft foods are the rule while the bone heals, and very hard foods or ice can still chip a crown or bridge.
Which is better for seniors: dentures or dental implants?
Neither dentures nor implants are better for every senior, because general health, bone, healing and budget matter more than age. Implants can be a reasonable choice at 70 or older when health and bone allow, and dentures or an implant-held denture are less involved options worth comparing.
Can you sleep with implant dentures?
Whether you sleep with an implant denture depends on the type. A removable implant-held denture is usually taken out at night to rest the gums and be cleaned, though your dentist may advise otherwise for your case. A fixed full arch stays in at night, since only the dental team can take it off.
What do I wish I knew before dental implants?
People weighing implants are usually glad to learn early that the process takes months, that bone has to be checked first, and that cleaning around implants is a daily habit. Ask what a quote covers, since extractions, grafts and scans can be separate.
Is it cheaper to get dentures or implants?
Dentures are generally cheaper than implants up front. At Redondo Beach Dental Group a single implant typically costs $3,000 to $6,000 including the abutment and crown, and All-on-4 typically costs $20,000 to $30,000 per arch, so ask for an estimate on each option you are considering.
