How long does swelling last after an apicoectomy?
Cited to 4 sources. Reviewed 2026-08-25.
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.
- Swelling peak
- 48 to 72 hours
- Mostly resolved
- Day 5 to 7
- Bruising appears
- Day 2 to 3
- Bruising fades
- 1 to 2 weeks
What to expect, step by step
Swelling begins. The lip or cheek over the surgical site starts to feel tight and full, often more noticeably in the evening than right after surgery.
What to do: Ice on the outside of the cheek, 20 minutes on then 20 minutes off, repeated through the day. Keep your head elevated, including on extra pillows overnight.
Peak swelling. Your face may look visibly asymmetric. Bruising can surface now, and can travel downward with gravity toward the jawline or up toward the eye on upper teeth.
What to do: Stop ice once the swelling has plateaued and switch to gentle warm compresses, which help the trapped fluid and bruising clear. Keep eating soft food and stay off the gym.
Steady improvement. Swelling should be smaller each morning than the morning before. Bruising changes color from purple to green to yellow as it breaks down.
What to do: Continue warm compresses, gentle salt water rinses, and normal hydration. Call your endodontist if the swelling is growing again rather than shrinking.
Swelling should be gone or nearly gone. A firm, slightly tender ridge over the surgical site can persist for longer as the tissue remodels.
What to do: Resume normal brushing around the area. Report any swelling that has returned, which is a different problem from swelling that never fully left.
Why swelling peaks two days later instead of right away
Swelling after an apicoectomy is inflammatory, not a sign that anything went wrong. Lifting the gum flap, removing infected tissue, trimming the root tip and placing sutures all provoke a normal inflammatory response, and that response takes a day or two to reach full volume. The American Association of Endodontists describes some discomfort or slight swelling while the incision heals as normal for any surgical procedure.
The practical consequence catches a lot of people off guard: you can feel fine leaving the office and look worse two mornings later. Swelling that is still increasing on day 2 is expected. Swelling that is still increasing on day 4 is not, and is worth a call.
Ice first, then heat
The two tools do different jobs and the order matters. Cold narrows blood vessels and limits how much fluid collects, so it is useful only while swelling is still forming, which is roughly the first 24 to 48 hours. Standard dental surgery guidance is an ice pack wrapped in a clean towel against the cheek for 20 minutes on, 20 minutes off, repeated several times a day. Never put ice directly on skin.
Once swelling has stopped growing, cold no longer helps. Gentle warmth increases circulation to the area, which helps clear the pooled fluid and speeds up how fast bruising breaks down. Warm, not hot, and on the outside of the face.
- Ice: first 24 to 48 hours, 20 minutes on and 20 off, wrapped in a towel
- Heat: after the swelling plateaus, usually starting day 2 or 3
- Head elevated on pillows for the first two nights
- No strenuous exercise for the first 48 to 72 hours, which makes swelling worse
- Do not pull your lip or cheek out to look at the site, which stretches the incision and adds swelling
Bruising is common and usually looks worse than it is
Bruising happens because a small amount of blood leaks into the soft tissue during surgery and then tracks along tissue planes under the skin. On upper teeth it can appear on the cheek or under the eye. On lower teeth it tends to slide down toward the jaw and neck.
It typically shows up a day or two after the surgery, not immediately, and moves downward as it resolves, which is why a bruise can appear in a place you were not even operated on. Expect the standard color sequence over one to two weeks. Bruising that is spreading rapidly, or is accompanied by increasing pain and firmness, should be evaluated rather than waited out.
Call your dentist or oral surgeon if
- Swelling that increases after day 3 rather than decreasing
- Swelling that returns after it had already gone down
- Fever of 100.4 F or higher, chills, or a general unwell feeling
- Pus, foul taste, or drainage from the incision
- A swollen area that is hot, hard and increasingly painful to touch
- Swelling spreading toward the eye, under the jaw, or into the neck
- Difficulty swallowing, opening your mouth, or breathing (seek emergency care immediately)
Related questions
Is it normal to have no swelling at all after an apicoectomy?
Yes. Front teeth and small surgical sites often produce very little visible swelling, especially if you iced consistently on day 1. Little swelling is a good sign, not a sign the surgery was incomplete.
How long should I use ice after an apicoectomy?
Roughly the first 24 to 48 hours, in 20 minute on and off cycles. Ice only helps while swelling is still forming, so continuing it past the peak adds nothing.
Why do I have a bruise under my eye after surgery on a back tooth?
Blood that leaked into the soft tissue during surgery travels along tissue planes under the skin, so the bruise often surfaces somewhere other than the surgical site. It is not a sign of a complication by itself.
Can I take ibuprofen for the swelling?
Over the counter pain relievers are commonly recommended after endodontic procedures, but follow the specific instructions your endodontist gave you and check with them before adding anything to your existing medications.

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.
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.
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.
Non-dissolving apicoectomy stitches are typically removed at a short follow-up visit within the first week, often between 2 and 7 days after surgery. Some endodontists remove them as early as 48 hours because the gum flap seals quickly. Dissolving sutures are left alone and usually break down and fall out within one to two weeks. Removal itself takes a minute or two and rarely needs anesthetic.
