What should I do in the first 48 hours after an apicoectomy?
Cited to 4 sources. Reviewed 2026-08-25.
For the first 48 hours after an apicoectomy: ice the outside of your cheek 20 minutes on and 20 minutes off, keep your head elevated, eat cool soft foods, and do not lift your lip or cheek to inspect the stitches. Skip strenuous exercise, smoking and straws. Do not chew, drink hot or cold liquids, or smoke for the first hour. Start gentle salt water rinses only when your endodontist tells you to, and never spit forcefully.
- Nothing by mouth
- First hour
- Ice cycle
- 20 minutes on, 20 off
- No strenuous exercise
- 48 to 72 hours
- Never do
- Pull your lip out to look
What to expect, step by step
Still numb, gauze possibly in place, light oozing from the incision.
What to do: Nothing to eat, drink or smoke. Keep any gauze in place with gentle pressure. Go home and sit down.
Numbness fading, soreness starting as the anesthetic wears off, swelling beginning to build.
What to do: Start the ice cycle. Take pain medication as directed before the numbness fully wears off. Cool soft foods once you can feel your lip. No rinsing or spitting.
The site feels tight. Sleeping flat makes swelling worse by morning.
What to do: Sleep with your head elevated on extra pillows. Put a towel on the pillow in case of light oozing. Keep taking medication on schedule rather than waiting for pain.
Swelling near its peak, possible bruising appearing, pain usually starting to ease even while the face looks worse.
What to do: Continue ice while swelling is still growing, then switch to gentle warmth once it plateaus. Begin gentle salt water rinses if instructed. Still soft foods, still no gym.
The one thing people get wrong: do not lift your lip
The most common self-inflicted problem in the first two days is inspection. It is a natural urge to pull your lip or cheek outward in front of a mirror to see the stitches, and it is the fastest way to cause trouble.
In an apicoectomy the gum was lifted off the bone and stitched back down. That flap reattaches over the following days. Stretching the lip pulls directly on the suture line, and it can tear the flap loose, open the incision, restart bleeding and add swelling. It also hurts.
Look with your mouth relaxed if you must look at all. Better yet, do not. If something feels wrong, call the office and let them retract the tissue properly.
The first 48 hours checklist
Everything on this list serves one of three goals: limit swelling, protect the clot and the flap, and keep the site clean.
- Ice the outside of the cheek, 20 minutes on and 20 minutes off, wrapped in a clean towel, never directly on skin
- Keep your head elevated, including with extra pillows overnight
- Take pain medication on the schedule you were given, ideally before the anesthetic fully wears off
- Eat cool or lukewarm soft foods, and chew on the opposite side
- Do not rinse, swish or spit forcefully on day one
- Do not use straws
- Do not smoke or vape, which is linked to poorer surgical outcomes
- No alcohol while taking prescription pain medication
- No strenuous exercise or heavy lifting
- Do not pull your lip or cheek out to inspect the surgery
- Brush your other teeth normally and stay gentle near the incision
Rinsing: gentle, and only when told
Rinsing too early or too hard is the second common mistake. In the first 24 hours the priority is leaving the site completely alone so the clot stabilizes and the flap seals. Vigorous swishing or spitting creates pressure that works against both.
Once your endodontist gives the go ahead, usually the day after surgery, rinse with warm salt water by tilting your head and letting the liquid move gently over the area, then letting it fall out of your mouth into the sink. No forceful swishing, no spitting.
Some endodontists prescribe an antimicrobial rinse instead, used the same gentle way. Follow whichever you were given rather than mixing both.
Bleeding, oozing, and what is actually normal
A small amount of oozing that tints your saliva pink for the first several hours is expected and is not bleeding in any meaningful sense. A little blood mixes with a lot of saliva and looks alarming.
Real bleeding is bright red, steady, and does not stop. If that happens, place a folded piece of clean damp gauze over the incision and hold firm, continuous pressure for 20 to 30 minutes without lifting it to check. Sit upright while you do it. If it is still flowing after that, call your endodontist.
Avoid anything that raises blood pressure in the first day: exercise, heavy lifting, hot showers, alcohol and bending over repeatedly.
Call your dentist or oral surgeon if
- Bright red bleeding that continues after 20 to 30 minutes of firm continuous gauze pressure
- Pain that is escalating rather than easing after the first day, or that your medication does not touch
- Swelling that is still growing after day 3
- Fever of 100.4 F or higher, or chills
- Pus, thick cloudy discharge, or a foul taste from the incision
- Numbness in the lip or chin still present 24 hours after surgery
- A rash, hives or itching after taking prescribed medication
- Difficulty swallowing, difficulty breathing, or swelling spreading into the neck (seek emergency care immediately)
Related questions
Can I rinse with salt water the day of my apicoectomy?
Usually not on day one. Leave the site alone so the clot and flap stabilize, and start gentle rinses when your endodontist tells you to, typically the following day. Let the water fall out rather than spitting.
Should I sleep sitting up after an apicoectomy?
Elevated, not upright. Extra pillows for the first two nights meaningfully reduce how swollen you wake up. Lying flat lets fluid pool in the face overnight.
When can I brush my teeth after an apicoectomy?
Brush your other teeth normally the same day. Stay gentle right at the incision line until the stitches are out, and let rinsing rather than brushing do the cleaning at the site.
Is it normal for my saliva to look pink?
Yes, for the first several hours. A small amount of oozing tints a lot of saliva. Steady bright red bleeding that does not respond to 20 to 30 minutes of firm pressure is different and should be reported.

Most people are back to normal activities the day after an apicoectomy. Swelling peaks around 48 to 72 hours, stitches usually come out within the first week, and the gum incision has closed over by about 2 weeks. The bone around the trimmed root end heals much more slowly, filling in over several months, which is why your endodontist checks it with follow-up X-rays rather than asking how you feel.
Swelling after an apicoectomy builds for the first two days, peaks somewhere around 48 to 72 hours, and then comes down over the rest of the week. Most people look close to normal by day 5 to 7. Bruising on the cheek or under the eye often shows up on day 2 or 3, after the swelling has already started, and can take one to two weeks to fade through the usual purple to yellow color change.
Stick to cool, soft foods for the first 24 hours after an apicoectomy, then soft foods you barely have to chew for about a week. Chew on the opposite side of your mouth the entire time. Avoid hard, crunchy, seedy or sticky foods, anything very hot, and drinking through a straw in the first days. Do not chew, drink hot or cold liquids, or smoke for the first hour after the procedure.
Most people return to normal daily activities the day after an apicoectomy, but strenuous exercise should wait about 48 to 72 hours. Raising your heart rate and blood pressure too early can restart bleeding at the incision and make swelling worse, and heavy lifting adds the same pressure. Ease back in with light cardio first, save maximal lifting and contact sports for after the stitches are out, and stop if the site throbs.
