What to Expect on Your All-on-4 Surgery Day

Most of the anxiety about All-on-4 surgery comes from not knowing what's going to happen. Here's an honest, step-by-step account of surgery day — from the morning you wake up to the moment you walk out with your new teeth.

The Week Before: Prep That Actually Matters

All-on-4 surgery day itself is long — usually four to six hours in the chair. The week before is when you set yourself up for a smooth recovery.

• Fill your prescriptions early. You'll be prescribed an antibiotic (to start the day before surgery), an anti-inflammatory, and pain medication. Don't wait until the night before to pick them up.
• Stock your kitchen. The first week you'll be on a liquid and very soft food diet. Think protein shakes, soup broth, Greek yogurt, applesauce, mashed potatoes, smoothies. Cold foods help with swelling.
• Arrange your ride. You will not be driving yourself home under any circumstances. IV sedation means you need a responsible adult to take you home and stay with you for several hours. This is non-negotiable.
• Set up your recovery space. Extra pillows to keep your head elevated, a recliner if you have one, entertainment you can engage with passively. You won't feel like doing much the first two days.

Surgery Morning: What to Do (and Not Do)

Wear comfortable, loose-fitting clothes with short sleeves — the anesthesiologist needs easy access to your arm for the IV. Avoid jewelry, especially anything you'd be upset about losing. Leave the contacts at home; glasses are fine.

Take your prescribed antibiotic with the smallest possible sip of water if instructed. No other medications unless your pre-op instructions specifically say otherwise. When in doubt, call us the day before — it's never a silly question.

Arrive 15–20 minutes early. Your surgical team will go through a final health questionnaire, confirm your medication list, review the consent forms, and take pre-op photographs. We use these photos to document your starting point and monitor your progress over the months ahead.

What Happens in the Chair

Once you're settled in, the team places the IV and administers sedation. Most patients describe the experience as going from wide awake to completely relaxed within about 60 seconds. You'll drift into a calm, sleep-like state — aware that something is happening but not experiencing pain or distress.

While you're sedated, here's the sequence:

1. Any remaining teeth in the arch being treated are extracted, if needed.
2. The gum tissue is prepared and the four implant sites are precisely located using your pre-surgical 3D cone beam CT scan as the guide.
3. The four titanium implant posts are placed at carefully calculated angles — two upright in the front, two angled in the back to maximize contact with available bone.
4. Abutments (the connector pieces) are attached to the implants.
5. Your temporary arch — custom-fabricated in advance from your impressions — is screwed into place.

Total surgical time is typically three to five hours for one arch, five to seven hours for both arches in the same day. You won't experience any of it consciously.

The First Few Hours After Surgery

You'll wake up in a recovery area with one of our team members monitoring you. The sedation wears off gradually — most patients feel groggy, a little disoriented, and emotionally raw for 30 to 60 minutes. Crying is common. It's not pain; it's a normal neurological response to anesthesia wearing off.

The local anesthesia that was placed during surgery will keep you fully numb for several hours after you wake up. You may not feel discomfort until that evening. When you do, stay ahead of it: take your pain medication on schedule rather than waiting until the pain is severe.

Before you leave, we'll review post-op instructions with your driver — not just with you, because you may not retain everything clearly in the sedation recovery window. We'll send the instructions home with you in writing and by email.

The First 72 Hours: What's Normal, What's Not

Knowing what's expected makes recovery far less stressful. Here's what you should anticipate:

What you'll notice	Normal?	What to do
Swelling, especially cheeks and jaw	Yes	Ice packs, 20 min on / 20 min off for the first 24 hours. Peaks at 48–72 hours.
Bruising on chin, jaw, or neck	Yes	Normal. Resolves within 1–2 weeks.
Slight bleeding or pink-tinged saliva	Yes (day 1)	Bite gently on gauze. If heavy bleeding continues past 2 hours, call us.
Sore throat or difficulty swallowing	Yes	From the breathing tube used during sedation. Resolves in 2–3 days.
Implants feeling loose or "clicking"	No	Call us immediately.
Fever over 101°F after day 2	No	Call us. Could indicate infection — we'll want to evaluate you.

Keep your head elevated, even while sleeping. This reduces swelling significantly. Don't rinse, spit, or use a straw for the first 24 hours — negative pressure can disrupt the clots forming around the implant sites.

Your Temporary Teeth

You'll leave the office with a full set of temporary teeth already attached to your implants. They look like real teeth and function well enough for soft foods. Most patients are genuinely shocked — they expected to go through a phase of looking worse before looking better. The opposite is true: you'll look dramatically better immediately.

These temporary teeth are not your final restoration. They're designed to be gentler on the healing implants while osseointegration occurs — the biological process where the implants fuse to your jawbone. You'll eat soft foods, avoid anything hard or chewy, and be careful not to put excessive pressure on the implants for the first three months.

Timeline to Your Final Smile

The All-on-4 procedure in Los Angeles typically follows this progression after surgery day:

Milestone	Timeframe
Suture removal (if needed)	1–2 weeks post-surgery
Initial healing check	4–6 weeks
Osseointegration confirmed	3–4 months
Final impressions taken	4–5 months
Final zirconia or hybrid arch placed	5–6 months

The final arch — typically zirconia or a high-strength hybrid — is stronger, more natural-looking, and permanently fixed. It's the restoration you'll have for the rest of your life with proper care. The wait for it can feel long, but the temporary teeth are comfortable and functional enough that most patients forget they're temporary.

The best thing you can do on surgery day is show up prepared, have someone you trust with you, and lean on your care team for any question that comes up — before, during, or after. That's what we're there for.
