A little swelling after tooth extraction is part of normal healing. Swelling that keeps growing days later and creeps towards your eye is different. It can mean an infection is spreading into the soft tissue of the face, and it needs prompt attention from an emergency dentist or a hospital team.
Infection after a tooth extraction is uncommon. A six-year review of extraction records found that only 1.4% of patients developed an infection, and giving antibiotics did not lower that number.
This guide explains how normal swelling after tooth extraction behaves, which signs point to infection, when antibiotics help, and what to do next.
How Long Does Swelling Last After a Tooth Extraction?
Swelling after tooth extraction is the body’s repair response. Extra blood and fluid flow into the gum and cheek to start healing the empty socket. That fluid shows on the outside of your face as puffiness.
This swelling usually builds over the first 48 hours and peaks around day two or three. After the peak, it should ease bit by bit and mostly settle within a week. A surgical or wisdom tooth extraction can take up to 10 days to settle fully.
Mild bruising, a stiff jaw, and a little blood in your saliva are common in the first few days and can all be part of normal healing. What matters most is the direction the swelling moves in. Healthy swelling shrinks a little each day after it peaks.
Signs of Infection After a Tooth Extraction
An infection usually shows up later than normal healing swelling. Infection-related pain and swelling tend to worsen around four to six days after the extraction. That’s when you would expect to be feeling better.
Bruising and infection can look alike at first, but they feel different. A bruise is usually flat, changes colour as it fades, and does not throb. Infected swelling often feels hot, tight and tender, and it keeps growing.
Other signs of infection include:
- throbbing pain that painkillers barely ease
- a bad taste or pus coming from the socket
- swollen glands under the jaw or in the neck
- a high temperature
Feeling generally unwell alongside the swelling suggests the infection may be affecting more than just your mouth.
Some extractions carry a higher risk of infection than others. In the same six-year review, complex extractions, such as those needing surgery, had about twice the odds of infection compared with simple ones.
Why a Tooth Infection Can Cause Swelling Near the Eye
Swelling that climbs towards the eye usually starts from an upper tooth. The roots of the upper back teeth sit close to the sinus above them. That sinus lies directly beneath the bony socket that holds the eye.
When infection from an upper tooth spreads through these spaces, it can reach the tissue around the eye. This condition is called orbital cellulitis. Research suggests that around 2 to 5% of orbital cellulitis cases begin with a dental infection.
Orbital cellulitis is rare, but delayed treatment can threaten your eyesight. So treat any swelling after tooth extraction that spreads toward the eye, closes the eyelid, or makes the eye painful as urgent.
When Facial Swelling After Tooth Extraction Is an Emergency
Some symptoms mean an infection may be spreading quickly and needs hospital care the same day. Call 999 or go to A&E if any of the following apply:
- Swelling reaching the eye: your eyelid is puffy, your eye hurts, or your eyesight suddenly changes.
- Breathing or swallowing problems: breathing, speaking, or swallowing feels harder than usual.
- Heavy swelling inside the mouth: the inside of your mouth is very swollen, making it uncomfortable to move your tongue.
- A jaw that will not open: opening your mouth wide enough to eat or talk has become difficult.
Do not drive yourself to hospital when your face or eye is swollen. Ask someone to take you, or call 999 for an ambulance. Bring a list of any medicines you take.
If the swelling is getting worse but is nowhere near your eye, and you can breathe and swallow normally, contact your dental practice the same day. If the practice is closed, call 111 for advice on urgent dental care. A GP surgery cannot provide dental treatment.
Do You Need Antibiotics After a Tooth Extraction?
Most tooth extractions do not need antibiotics afterwards, because normal swelling after tooth extraction is not caused by bacteria. Antibiotics are used when an infection is spreading, such as swelling that keeps growing across the face. They are also used when an infection is affecting the whole body, with a high temperature and feeling unwell.
Swelling that has spread up towards your eye counts as spreading, so antibiotics are likely to be part of your treatment. People with a weakened immune system, for example during chemotherapy, may also be given antibiotics sooner. For them, infections can turn serious more quickly.
Antibiotics rarely clear a dental infection on their own. A pocket of pus has very little blood supply, so tablets struggle to reach the bacteria inside it. That is why draining the pus and cleaning the area usually comes first.
Whether you are treated at a local clinic or by a private dentist, the decision to prescribe follows the same clinical rules. Those rules exist to keep antibiotics working for the times you truly need them.
When Antibiotics Will Not Help Swelling After Tooth Extraction
Normal swelling and bruising in the first two or three days come from healing, so antibiotics will not make them go down faster. Taking antibiotics at this stage only adds the risk of side effects, such as feeling sick, bloating and diarrhoea.
Dry socket is another problem that antibiotics do not fix. It happens when the blood clot in the empty socket breaks down, causing deep pain and a bad taste, usually with little swelling. A dentist treats dry socket by gently cleaning the socket and placing a soothing dressing inside it.
Why Leftover Antibiotics Can Make Things Worse
Taking tablets left over from an old prescription, or borrowing some from a relative, can seem like a quick fix. Leftover antibiotics may be the wrong type or the wrong amount for a dental infection. Meanwhile, the infection can keep spreading while you wait for them to work.
Using antibiotics without a proper check also helps bacteria learn to resist them. That resistance can make antibiotics less likely to work for you when a serious infection does need treating.
What Happens at an Urgent Dental Appointment for Facial Swelling
An emergency dentist will first ask when your tooth was removed and how the swelling has changed since then. This timeline helps tell normal healing apart from an infection that began a few days later. Mention any allergies, especially to penicillin, because this changes which antibiotic can be used.
Next, the dentist will look at the socket and feel your face and neck for tender or swollen areas. They may also check your temperature. An X-ray may be taken to look at the socket and the bone around it.
If pus has collected, the dentist may drain it under local anaesthetic, which numbs the area so you do not feel pain. If the swelling has reached your eye or is spreading fast, you will be referred to a hospital team who specialise in the face, mouth and jaw. There, antibiotics may be given through a drip and a scan may be arranged.
How to Ease Swelling at Home While You Wait for Care
Home care can ease discomfort and swelling after tooth extraction, but it cannot cure a spreading infection. Use these steps alongside getting help, never instead of it:
- Pain relief: paracetamol or ibuprofen can ease soreness. Follow the dose on the packet, because taking more will not make them work better.
- Warm salt water rinses: from the day after the extraction, gently rinse with a teaspoon of salt in a glass of warm water, up to four times a day, to keep the socket clean.
- Soft, lukewarm food: soup, scrambled eggs and mashed potato are easier on a sore jaw. Avoid very hot food and drink for the first two days, as heat can start the socket bleeding again.
- No smoking: smoking slows healing and raises the chance of dry socket, so avoid it for at least the first two days.
- A daily photo: take a photo of your face at the same time each morning. This makes it much easier to see whether the swelling is shrinking or spreading.
Know When Swelling Is Healing and When It Is Spreading
When healing goes well, swelling after tooth extraction follows a clear pattern: it rises, peaks within two or three days and then fades. Swelling that grows after that point, feels hot and tight, or creeps towards your eye is a sign of infection.
Antibiotics have a real place in treating that kind of infection, but they work best alongside treatment that clears the source. They should always come from someone who has examined you, never from an old prescription.
If the swelling is getting worse but is less severe, contact an emergency dentist today so the infection can be treated before it spreads further.
