All-on-4 recovery runs on two clocks. Swelling and soreness peak around day three and mostly settle within two weeks, which is when most people return to work and normal routines. Underneath, the implants need three to six months to fuse to the bone. The soft diet belongs to that second window, not the first, which is why it continues long after you feel fine.
Why does recovery run on two different clocks?
Because the part you feel and the part that matters heal on completely different schedules, and confusing them is the most common reason full-arch cases run into trouble.
Clock one is your comfort. Gums, cheeks and soft tissue. Swelling peaks around 48 to 72 hours, then falls away steadily. By day ten to fourteen most people look and feel normal.
Clock two is osseointegration. This is the process where bone cells grow into the microscopic surface of each titanium implant and lock it in place. It takes three to six months, it produces no sensation whatsoever, and you cannot tell by feel whether it is going well.
Think of it like a cast on a broken arm. The bruising fades in two weeks. The bone underneath is not ready at two weeks, and taking the cast off early because the arm no longer hurts is how people re-break things.
That mismatch is where All-on-4 patients get into difficulty. At week three you feel completely recovered, and the soft food restriction starts to feel arbitrary and slightly ridiculous. So someone bites into a bagel, and either fractures the temporary bridge or, worse, applies enough force to an implant that has not fully fused to disturb it.
The single most useful thing to understand about All-on-4 recovery: the diet restriction is not tracking your comfort. It is tracking your bone.
What do the first 72 hours feel like?
The worst of it, and it is more manageable than most people expect going in.
You will leave the appointment with a fixed set of temporary teeth already in place, so you never go out in public without a smile. You will also be numb, groggy if you had sedation, and you will need someone to drive you home.
What is normal in the first three days:
- Swelling that increases through day two and peaks around day three, often including the cheeks and sometimes under the eyes
- Bruising along the jaw and neck, which can appear a day or two later and can look dramatic
- Oozing rather than bleeding for the first several hours
- Aching that responds to prescribed or over-the-counter pain relief
- Difficulty opening wide
What actually helps:
Ice on the outside of the face, twenty minutes on and twenty off, for the first 48 hours. After that, switch to warm compresses, which help the swelling drain rather than keeping it in place. Sleep propped up on two or three pillows for the first three nights, because lying flat sends fluid straight to your face. Stay ahead of the pain rather than chasing it, which means taking medication on schedule for the first two days instead of waiting until it hurts.
Eat cold and soft. Yogurt, smoothies without a straw, cooled soup, pudding, mashed potato. No straws for at least a week, because the suction can disturb clotting at the surgical sites.
What about the rest of week one?
Steady improvement, and the point at which most people stop feeling like a patient.
Swelling drops noticeably from day four onward. Bruising changes colour and fades. If you were prescribed antibiotics, finish the full course rather than stopping when you feel better, and follow your dentist’s guidance on how long to take them.
Start gentle salt-water rinses after 24 hours, or a prescribed rinse if you were given one. Do not swish forcefully. Let it move around your mouth and let it fall out rather than spitting hard.
You can brush your remaining natural teeth normally from day one. Around the surgical sites and the new bridge, use a soft brush gently, and expect this to feel strange rather than painful.
Food widens slightly this week: scrambled eggs, flaked fish, well-cooked pasta, refried beans, anything that yields to a fork without pressure.
When can you go back to work?
Most people are back within three to five days for desk work, and one to two weeks for physically demanding jobs.
The honest variables are how many teeth were extracted, whether both arches were treated at once, and how visible your swelling is. Nobody is medically unfit to answer emails on day three. Plenty of people would rather not be seen on a video call with a swollen face on day three, and that is a legitimate reason to take the week.
Reasonable planning guidance:
| Type of work | Typical return |
|---|---|
| Desk-based, working from home | 2 to 3 days |
| Desk-based, in office or client-facing | 5 to 7 days |
| Physical labour or heavy lifting | 10 to 14 days |
| Both arches treated in one appointment | Add 2 to 3 days to any of the above |
Avoid strenuous exercise and heavy lifting for at least a week regardless of your job. Raising your blood pressure meaningfully in the first days increases bleeding and swelling.
Planning your time off around surgery?
Recovery is far easier to organize when you know which weeks need clearing. We map that out before surgery rather than after.

Why is the soft diet still on at week six?
Because clock two is still running, and this is the section worth reading twice.
By week six your gums have healed. You feel entirely normal. And your implants are somewhere in the middle of fusing to bone, which is a process measured in months and produces no symptoms at any stage.
Two specific risks make the restriction necessary.
Micromovement. An implant that shifts even fractionally under heavy load during integration may fuse imperfectly or fail to fuse at all. The bone needs a stable surface to grow against. Hard chewing introduces exactly the movement it cannot tolerate.
Provisional fracture. Your temporary bridge is acrylic. It is designed to look right and function reasonably, not to survive a crusty baguette. Fracturing it means an unscheduled repair appointment and, occasionally, time without fixed teeth while it is remade.
What to keep avoiding through the fusion window:
- Hard: nuts, ice, hard candy, raw carrots, crusty bread
- Sticky: toffee, caramel, chewing gum
- Tough: steak, jerky, anything requiring sustained tearing
- Anything you would have to bite into with real force at the front
You are not restricted to liquids. You can eat a genuinely good diet of ground meat, fish, eggs, cooked vegetables, pasta, rice, cheese, soft fruit and bread without crust. Protein matters here, because healing consumes it.
Smoking during this window does more damage than at any other time, since it directly compromises the blood supply the bone needs to grow.
When do the permanent teeth go on?
Between three and six months after surgery, once your dentist confirms the implants have integrated.
The final appointments involve new impressions or a digital scan, a try-in, and then fitting the definitive bridge. Compared with the temporary, the final bridge is made from stronger material, fits more precisely, and is contoured to let you clean underneath properly.
What changes when it goes on:
- You transition off the soft diet, usually over a week or two rather than overnight
- The bite gets adjusted carefully, and small refinements over a few visits are normal
- Speech settles within days if the shape has changed
- Cleaning becomes a permanent daily routine, built around a water flosser
The whole arc, from surgery to final bridge, matches the timeline for implant treatment generally, with the difference that All-on-4 patients have fixed teeth throughout instead of waiting with a gap.
At Forest Hills Dental, Dr. Gregory Mark plans these cases with 3D imaging and guided placement, and monitors integration at scheduled checks through the healing window. If something is not progressing as expected, the point of those appointments is to catch it early rather than at month five.
What’s not normal, and when should you call?
Most All-on-4 recoveries are uneventful. These are the signs that warrant a phone call rather than a wait-and-see.
| Sign | When it matters |
|---|---|
| Pain increasing after day four | Should be steadily improving by then, not worsening |
| Swelling worsening after day four | Peak is day three. Growth after that suggests infection |
| Fever above 101F | Call the same day |
| Bad taste, pus or foul odour | Infection until proven otherwise |
| Any movement in the bridge | Call immediately, do not test it repeatedly |
| Persistent numbness in the lip or chin past 48 hours | Report promptly, particularly in the lower jaw |
| Bleeding that does not settle with firm gauze pressure | Call rather than waiting it out |
If you are healing and something feels wrong, call. It is a five-minute conversation, and everyone involved would rather have it early.

TL;DR
- Two clocks run at once. Comfort resolves in about two weeks. Bone fusion takes three to six months.
- Swelling peaks around day three, then falls away. Ice for 48 hours, then switch to warmth.
- Most people return to desk work in 3 to 5 days, and physical work in 10 to 14.
- The soft diet tracks bone healing, not comfort, which is why it continues weeks after you feel completely fine.
- You have fixed temporary teeth the entire time. You are never without a smile.
- Final bridge goes on at three to six months, after integration is confirmed.
- Call if pain or swelling increases after day four, if you develop a fever, or if the bridge moves at all.
If you are already healing and something does not feel right, do not wait for your scheduled follow-up.

Frequently asked questions
How long are you without teeth with All-on-4?
You are not without teeth at any point. A temporary fixed bridge is attached the same day the implants are placed, usually within a few hours of surgery, and you wear it throughout the three to six month healing period until the permanent bridge replaces it.
Can you drive yourself home after All-on-4 surgery?
No. Full-arch implant surgery is performed under sedation or general anaesthesia in most cases, so you must arrange for someone to drive you home and ideally stay with you for the first several hours. Even with local anaesthetic alone, driving immediately after a long surgical appointment is not advisable.
Will you have a lisp after All-on-4?
Some patients notice a temporary lisp or altered speech in the first one to two weeks while the tongue adapts to the new shape of the bridge. This almost always resolves on its own. Reading aloud for a few minutes daily speeds up the adjustment noticeably.
How long should you stop smoking before and after All-on-4?
Stopping at least two weeks before surgery and staying off tobacco for at least eight weeks afterward is the general guidance. Smoking restricts the blood supply the jawbone needs to fuse with the implants, and it is the strongest lifestyle risk factor for implant failure during the healing period.
When can you exercise again after All-on-4?
Avoid strenuous exercise and heavy lifting for at least seven days, because raised blood pressure increases bleeding and swelling at the surgical sites. Light walking is fine from day one. Most patients return to a full exercise routine at two to three weeks, once swelling has fully resolved.
