Know Which One You Can Live With Before You Commit
All-on-4 vs dentures comes down to one difference, since one stays in and the other comes out every night. Dr. Heber Strobel, DDS, trained at Louisiana State University School of Dentistry and focuses on restorative care. His father, Dr. Dirk Strobel, DDS, trained at Creighton University School of Dentistry. He has practiced in Rexburg for over 40 years. You’ll see how each choice changes eating, cleaning, and repairs, with the research numbers behind each one.
Maybe you’ve worn a lower denture for years and you’re tired of it moving. You fear paying for surgery and hating the result. Money is only part of what’s at stake when you choose between the two. A fixed arch is anchored in your jawbone. That makes it far harder to undo than a denture you can set aside.
Can you take All-on-4 out at night?
No. An All-on-4 bridge screws onto 4 implants in the jaw and stays put, day and night. You don’t take it out yourself, which is the part long-time denture wearers find strangest at first. Many patients expect something closer to a snap-in denture.
A denture works the other way around. It lifts out at night, gets brushed in the sink, and sits in water while you sleep. Some people find that nightly routine comforting, since they can check and clean the whole thing by hand. Others have spent twenty years resenting the cup on the nightstand, and they want it gone for good.
Neither choice wins by default, and your jaw, your health, and your habits all weigh in. Our page on All-on-4 dental implants in Rexburg covers the procedure, the timeline, and what it costs here. What follows is how the two differ once you’re living with them.
What changes day to day when your teeth are fixed?
Five things change, and most show up in the first few months. Patients expect the eating difference. The rest tend to surprise them, and not always in a pleasant way, so hear all five first. Here’s the list, in the order most people notice it.
- No adhesive, no soaking cup, and nothing to lose on a camping trip
- Nothing shifts or clicks when you talk or laugh
- Surgery and healing come first, before the final teeth go in
- Cleaning moves from the sink to a daily routine under the bridge
- Very hard foods still need care, since a chipped bridge means a repair visit
Every patient weighs this trade a little differently, and it runs both ways. You give up the freedom to take your teeth out, and you gain teeth that stay put all day. Most people know quickly which side they’re on.
How do All-on-4 and dentures compare side by side?
A fixed arch is anchored by 4 implants, and a full denture has none. That one fact drives most of the rows below. Bite force is the row people ask about most, and the research there is thinner than many ads suggest.
| All-on-4 | Full denture | |
| Comes out at night | No, fixed in place | Yes |
| Implants per arch | 4 | None |
| Surgery | Yes, plus healing time | None |
| Bite force | Not measured in the 2025 study | About 55 N with dentures in both jaws |
| Bridge repairs over 12 years | 55.9 percent of patients had one | Not part of the 12-year study |
| Daily cleaning | Under the bridge, in place | Out of the mouth, in the sink |

The row to think hardest about is the one missing from the table, which is undoing it. A denture can go in a drawer if you change your mind. Implants stay in the bone either way. Be sure before you commit, because there’s no easy way back.
How much bite force do dentures give up?
About nine tenths of it. A 2025 study measured maximum bite force in 198 adults across seven groups. Complete dentures in both jaws averaged 55 newtons. People with a full set of natural teeth averaged 547, roughly ten times as much.
The same study did not test implant-supported full arches, so it can’t tell you where All-on-4 lands. Be wary of any All-on-4 bite force number quoted without a study. What the research does show is how much a full denture gives up, which is a lot. For many people, that alone explains the urge to switch.

What goes wrong with a fixed arch over time?
The bridge itself needs repairs far more often than the implants holding it fail. One 12-year study followed 111 patients. Their 532 implants survived at a rate of 92.5 percent, while the bridges survived at 96.2 percent. Repairs were common, though.
Mechanical problems with the final bridge reached 55.9 percent of patients over the 12 years. Counting the temporary bridge, 94.6 percent had one. Problems with the gums or bone around the implants reached 36 percent of patients. Those numbers sound alarming at first.
Most are chips, loose screws, and worn parts, so they mean visits rather than lost teeth. Ask any office how it handles those repairs and what they cost before you commit. None of that says the treatment fails. It says upkeep is part of owning one, so plan time and money for it. Results vary with every patient.

How do you clean teeth you can’t take out?
Differently than you’d guess, because a toothbrush alone won’t reach the gap under the bridge. The bridge sits a little above the gum, where food collects. Plan on 4 habits at home, plus regular checkups and professional cleanings with your dentist.
- A water flosser aimed under the bridge, every day
- A soft brush along the gum line where the bridge meets the tissue
- Floss threaders or small interdental brushes a few times a week
- Regular checkups so the area under the bridge gets cleaned well
Skipping this is how gum and bone problems start around the implants. Those are harder to fix than a chipped tooth. If that sounds like a lot, our page on implant-supported dentures covers the removable middle option. Some people find it easier to keep clean. Whether you live by Smith Park or out in Parker, it starts with an exam. Our office sits on Professional Plaza, off South 2nd East.

What Else Do Rexburg Patients Ask About All-on-4 and Dentures?
Will I taste food better with All-on-4?
Often, yes, especially with an upper denture. An upper denture covers the roof of your mouth, which can change how food tastes and feels. The NIDCR, part of the NIH, lists denture problems among causes of taste disorders. A fixed arch leaves the roof of your mouth open, though results vary from person to person.
Does the bridge ever need to come off?
Yes, but only your dentist removes it. Cleveland Clinic notes a fixed implant denture can’t be removed at home, but a dentist can remove it for maintenance. That visit lets the underside get cleaned. It also lets the implants and screws get checked, and then the bridge goes back on.
Can I get All-on-4 if I smoke?
Sometimes, though the odds shift with smoking, and you deserve to hear that plainly before you decide. Mayo Clinic notes smoking may play a part in implant failure. In the 12-year study above, implant survival was 71.4 percent for patients who smoked. It fell to 44.5 percent for smokers with a health condition. Ask about quitting before surgery.
Will dentures need adjusting over time?
Yes, and that’s normal. The ADA notes dentures usually need follow-up visits so the fit can be checked and adjusted. Your gums and jawbone slowly change shape over the years. A denture that once fit well can start to rub or slip around in your mouth. Call if a sore spot lasts more than a few days.
