A sinus lift is a procedure for the upper back jaw when there is not enough bone height for an implant: the thin membrane lining the floor of the sinus is gently lifted and bone graft material is placed underneath. How you look after yourself after sinus lift surgery matters almost as much as the procedure itself, because the graft needs to stay in place and turn into bone. In the first days and weeks, simple habits such as blowing your nose hard or drinking through a straw can put pressure on the sinus and disturb healing. This article explains what to expect, what to pay attention to in daily life and which symptoms mean you should contact your dentist.
What to expect in the first days after sinus lift surgery
The procedure is usually done under local anaesthetic, which wears off within a few hours. Afterwards, many people notice some of the following:
- Swelling: the cheek and sometimes the area under the eye may swell, usually peaking on day two or three and then easing.
- Bruising: bruising on the cheek or around the eye may appear and fade within one to two weeks.
- Tenderness and pain: mild to moderate pain is common and can usually be managed with the pain relief your dentist recommends.
- Slight nosebleed: a small amount of blood-tinged discharge from the nose is common for the first day or two.
- Blocked feeling in the nose: swelling in the sinus area can cause temporary congestion.
- Graft particles in the mouth: you may feel a few small, sand-like granules in the first days; a small amount is usually not a concern.
How strong these symptoms are depends on whether a closed (indirect) or open (lateral window) technique was used, the amount of graft and how your body heals. Swelling and bruising are usually more noticeable after the open technique.
Aftercare: what to pay attention to
The sinus membrane and the new graft are sensitive to pressure changes during the first weeks. Dentists commonly advise the following:
- Do not blow your nose: avoiding nose blowing for at least two weeks is often recommended. Gently wiping any discharge is enough.
- Sneeze with your mouth open: holding in a sneeze or sneezing with your mouth closed raises pressure inside the sinus.
- Avoid straws: sucking creates a pressure difference between the mouth and sinus.
- Skip strenuous activity: bending over, heavy lifting and intense exercise in the first days can increase swelling and bleeding.
- Flying and diving: because of pressure changes, wait for the period your dentist recommends before flying or scuba diving.
- Do not smoke: smoking reduces blood flow and can harm graft integration and wound healing.
- Keep your head raised: an extra pillow for the first few nights can help reduce swelling.
Cold compresses and medication
During the first 24 to 48 hours, a cold pack wrapped in a cloth and held on the cheek for 15 to 20 minutes at a time can reduce swelling. Your dentist may prescribe pain relief, antibiotics, a nasal spray or a decongestant. Take these exactly as directed, and do not add or stop medication on your own. Always tell your dentist about any other medicines you take.
Eating and oral hygiene
Soft, lukewarm foods are a good choice for the first days: yoghurt, soup, mashed potatoes, eggs and well-cooked vegetables all work well. Avoid very hot, hard, crunchy and spicy foods for a while, and try not to chew on the treated side. Drinking plenty of water and avoiding alcohol support healing. If swelling makes it hard to open your mouth, smaller bites and more frequent meals can help. If you have a long-term condition such as diabetes, regular meals and stable blood sugar are especially important during this period.
Good hygiene is part of healing, but the area needs a gentle touch:
- Avoid vigorous rinsing on the first day.
- From the following days, use the mouthwash your dentist recommends with gentle swishing.
- Brush your other teeth as usual, keeping the brush away from the surgical site and stitches.
- Leave the stitches alone and avoid pulling your lip to look at the area, as this can stretch them.
If you wear a removable denture, ask your dentist whether it presses on the treated area. In some cases it may need adjusting or should be left out for a while.
Healing and implant timing
Stitches are usually removed after seven to fourteen days, and the gum heals within a few weeks. Turning the graft into mature bone takes longer. After a closed sinus lift where the implant was placed at the same visit, a wait of three to six months is typical. After an open sinus lift, especially when very little bone was present, six to nine months or more may be needed before the implant is placed or loaded. You can read more about how healing times differ between the upper and lower jaws.
At follow-up visits your dentist checks how the wound is healing and, when needed, uses an X-ray or 3D scan to assess the graft. General information about the sinus lift procedure and bone grafting can also help you understand the process.
When to contact your dentist
Mild swelling and tenderness are expected, but contact your dentist without waiting for your next appointment if you notice:
- Pain or swelling that gets worse after a few days instead of better
- A fever above 38°C
- Foul-smelling, yellow-green nasal discharge or a bad taste in the mouth
- A nosebleed that does not stop or keeps returning
- A large amount of graft material coming from the nose
- Liquid seeping into the nose when you drink
- Stitches opening early
These signs can point to infection, sinusitis or a problem with the sinus membrane. Most of these can be managed when noticed early, although sometimes part or all of the graft does not take and the procedure needs to be repeated.
Frequently asked questions
When can I fly after a sinus lift?
This depends on the type of procedure and how you are healing. Many dentists advise avoiding flights for the first one to two weeks. If you have travel plans, discuss them with your dentist before the procedure.
How long does swelling last after a sinus lift?
Swelling usually peaks on day two or three and eases noticeably within five to seven days for most people. Bruising may take one to two weeks to fade. Contact your dentist if swelling increases or lasts longer than expected.
Will sneezing dislodge the graft?
Sneezing with your mouth open lowers the pressure in the sinus and usually causes no problem. Sneezing with your mouth closed and nose blocked can put pressure on the membrane. If you notice any worrying symptoms, ask your dentist.
When can I exercise after a sinus lift?
Light walking is usually fine after a few days. For heavy exercise, weight training and swimming, waiting one to two weeks is often advised. Your dentist will give you a timeframe based on your healing.
Final thoughts
The weeks after a sinus lift call for patience and care so the graft can mature into healthy bone. Whether you are in Kahramanmaraş or elsewhere, staying in touch with your dentist and keeping your follow-up appointments helps track your healing and plan the right implant treatment for you.
