After Tooth Care

What are the aftercare rules for the first week after a sinus lift?

Cited to 5 sources. Reviewed 2026-08-25.

Quick answer

The first week comes down to one idea: keep pressure off the sinus and keep the incision undisturbed. That means no nose blowing, sneezing with your mouth wide open, no straws, no smoking or vaping, no heavy lifting or strenuous exercise, sleeping with your head elevated, and soft cool food chewed on the opposite side. Ice the cheek for the first 48 hours. Most of these rules run longer than a week, so get your surgeon's end date for each.

Ice the cheek
First 48 hours
Sleep elevated
At least 1 week
No lifting over 10 lb
At least 2 weeks
No nose blowing
2-4 weeks (surgeon set)

What to expect, step by step

Day of surgery

Numbness for a few hours, then swelling starting. Pink drainage from the nostril on the surgical side. Grogginess if you were sedated.

What to do: Ice the cheek 20 minutes on and 20 off. Cool soft food. Take medication as prescribed. Rest with your head propped up. No rinsing, no spitting, no straws.

Days 1-3

Swelling and bruising peak. The cheek feels tight and full. Congestion is at its worst and there may be blood tinged drainage.

What to do: Keep icing through 48 hours, then switch to warm compresses if your surgeon suggested it. Stay off exercise. Sleep propped. Start the prescribed rinse only on the day you were told.

Days 4-7

Swelling falls, bruising yellows, and eating gets easier. Congestion often lingers after the swelling goes.

What to do: Ease back to light activity, not exercise. Keep chewing on the opposite side. Keep the no blowing and no straw rules going. Attend the follow up visit.

The pressure rules, and why every one of them exists

Your graft is loose particulate material sitting under a membrane that was lifted off the sinus floor days ago. Nothing anchors it. Anything that spikes the pressure inside your sinus can move it. That single fact explains most of the list:

  • Do not blow your nose. Dab and wipe instead. Complication reviews warn patients specifically to avoid raising pressure by blowing the nose after sinus augmentation
  • Sneeze with your mouth wide open. Cleveland Clinic gives this same instruction after sinus surgery. Never pinch your nose or stifle a sneeze
  • No straws. The suction pulls on a fresh incision line and the flap over the bone window
  • No heavy lifting. Cleveland Clinic advises against lifting more than 10 pounds for at least two weeks after sinus surgery
  • No strenuous exercise, bending over, or straining for the first week and often longer
  • No wind instruments. Reviews of sinus augmentation complications name them explicitly as a pressure risk
  • Ask before flying, and ask separately about scuba diving

Swelling, sleeping, and comfort

Swelling usually peaks around 48 to 72 hours and then falls. Ice the cheek in 20 minute cycles for the first 48 hours. Cleveland Clinic lists applying ice, eating soft foods, and elevating your head among the standard steps after a dental bone graft.

Sleeping elevated does two jobs at once. It reduces facial swelling and it eases congestion, which is the same reason Cleveland Clinic recommends an extra pillow after sinus procedures. Use a wedge or stack pillows so your head stays above your heart, and try to stay off the surgical side.

Take pain medication as prescribed rather than waiting for pain to build. Do not add aspirin or other blood thinning medication on your own, and tell your surgeon about anything you already take.

Keeping the mouth clean without disturbing anything

The incision runs along the gum above your upper back teeth. It needs to stay clean, but scrubbing or forceful rinsing is worse than leaving it alone.

Brush your other teeth normally and stay off the surgical area until your surgeon clears you. Use whatever rinse they prescribed, on the day they said to start, and let it fall out of your mouth rather than spitting. Cleveland Clinic specifically lists vigorous spitting among the things to avoid after a bone graft. Do not use a water flosser near the site and do not probe the area with your tongue or fingers.

Smoking is the one worth taking seriously

If you drop only one habit for this surgery, drop this one. A systematic review and meta analysis comparing smokers with nonsmokers after lateral maxillary sinus augmentation found a significantly increased risk of wound breakdown in smokers, and noted that combining smoking with onlay bone grafting significantly increased postoperative infection rates.

The broader implant literature agrees: cigarette smoking adversely affects wound healing and jeopardizes the success of bone grafting and dental implantation. Vaping is not an established safe substitute. This is one of the few variables in the entire timeline that you fully control.

Call your dentist or oral surgeon if

  • Swelling that gets worse after day 3 instead of better, especially with fever
  • Fever of 100.4 F or higher, pus at the incision, or a foul taste that keeps returning
  • Thick yellow or green nasal discharge with facial pain building over days: possible sinus infection
  • Sudden puffy swelling of the face with a crackling feel under the skin, usually right after a sneeze or nose blow: call the same day
  • Graft granules in your nose or mouth, or liquid passing between your mouth and nose
  • Bleeding from the nose that will not stop after 20 minutes of gentle pressure, or gum bleeding that will not stop with 30 to 45 minutes of gauze
  • Swelling around the eye, vision changes, or difficulty breathing or swallowing: go to emergency care

Related questions

When can I exercise again after a sinus lift?

Light walking is usually fine within a few days. Strenuous exercise and lifting raise sinus pressure, and Cleveland Clinic advises no lifting over 10 pounds for at least two weeks after sinus surgery. Get your specific clearance date from your surgeon.

Can I use a CPAP machine after a sinus lift?

Ask your surgeon and your sleep physician together before your first night back on it. CPAP delivers positive pressure into the nasal airway, which is the pressure route these precautions are built around. Do not change settings on your own.

Do I have to take antibiotics?

Many surgeons prescribe them around sinus augmentation because of the infection risk in an operated sinus. If yours did, finish the full course even once you feel fine. Do not start or stop antibiotics on your own.

When do the stitches come out?

Usually at a follow up visit in the first week or two, unless they dissolve on their own. Do not pull at loose stitch ends yourself. Report it if a stitch comes out early and the incision looks open.

What is the recovery timeline after a sinus lift?

Sinus lift recovery runs on two clocks. The surgical clock is short: swelling and bruising peak around day 2 to 3, and most people are back to normal daily life within 1 to 2 weeks. The biological clock is long: the graft under your sinus floor needs months to turn into real bone, and the American Academy of Periodontology says surgeons usually let it develop for 4 to 12 months before placing implants.

What can I eat after a sinus lift?

Start with cool or lukewarm soft foods for the first 2 to 3 days: yogurt, smoothies eaten with a spoon, applesauce, scrambled eggs, mashed potatoes, blended soup. Chew on the opposite side from the surgery. Skip straws, hot liquids, alcohol, and anything crunchy or sharp that could lodge in the incision. Most people are back to normal food by the end of week 2, though your surgeon may keep you soft for longer if the graft was large.

Why can't I blow my nose after a sinus lift?

Blowing your nose pushes pressurized air up into the maxillary sinus, and after a sinus lift the only thing separating that air from your fresh graft is a thin, recently lifted membrane. The pressure can shift or displace graft material, reopen the surgical window, or force air into the soft tissue of your face. Most surgeons ban nose blowing for at least 2 weeks and often 4, and case reports describe facial swelling appearing right after a patient blew their nose hard.

Can I sneeze after a sinus lift?

Yes, you will sneeze, and that is fine as long as you sneeze with your mouth wide open. Cleveland Clinic gives the same instruction after sinus surgery: always open your mouth to sneeze. A stifled sneeze, with your mouth shut or your nose pinched, sends the full pressure spike up into the maxillary sinus, where it can push graft material out of place or force air into your facial tissues. Never hold a sneeze in after a sinus lift.
