A tooth abscess is a pocket of infection that needs treatment from a dentist or doctor, so contact a dental office as soon as possible. Facial swelling can mean the infection is spreading, which makes prompt care important. While you wait for your appointment, you can manage discomfort as a healthcare professional advises. Do not try to cut or drain the abscess yourself, because that can push the infection deeper and cause serious harm.
Tooth abscess and facial swelling. Most need a dentist soon, a few need the ER.
Swelling in your face or gums almost always means an infection that a dentist can treat soon, and a small number of cases need an emergency room tonight. This page helps you tell which one you are looking at.
Why this matters
This page received a dental billing and coverage review for how it describes coverage and costs. The safety information follows standard guidance for a dental infection.
This page is educational and is not medical advice or a diagnosis. A dental infection needs care from a dentist or doctor. For trouble breathing or swallowing, spreading swelling, or a high fever, call emergency services or go to a hospital emergency room. Do not try to drain or cut a swelling yourself.

Dentist or ER
A quick safety check.
Quick answer
A tooth abscess is a dental infection that needs prompt care. Most cases need a dentist within about a day, since infection does not clear on its own and antibiotics alone do not cure it. Go to a hospital emergency room or call emergency services for trouble breathing or swallowing, swelling spreading to the eye or neck or the floor of the mouth, a high fever, or feeling very unwell. Do not try to drain or cut a swelling yourself.
This is a safety check, not a diagnosis. It cannot see you or examine you. If you feel scared or unsure at any point, treat it as an emergency and get medical help.
Warning signs
Go to the ER now if any of these are true.
Think of these as a quick safety check, not a verdict. If any of them fit you, go to the emergency room now and let a dentist follow up after. A dental infection sits close to the airway and the spaces in the neck, so swelling that spreads there can become dangerous within hours.
Call emergency services or go to the ER for
- Trouble breathing or swallowing, or drooling because you cannot swallow your saliva
- Swelling spreading toward the eye, down into the neck, or under the tongue along the floor of the mouth
- A high fever, chills, or feeling very sick
- Swelling that is getting worse quickly, or that feels firm and hard
- Confusion, a racing heartbeat, fast breathing, dizziness, or cold clammy skin
An emergency room can protect the airway, give medicine through a vein, and drain the infection, but it usually cannot do the dental work itself, so you will still need a dentist to fix or remove the tooth afterward.
What it is
What a tooth abscess is, in plain words.
A tooth abscess is a pocket of pus caused by a bacterial infection in or around a tooth. A periapical abscess starts inside the tooth, at the tip of the root, when bacteria reach the soft inner tissue through a deep cavity, a crack, or older dental work. A periodontal abscess starts in the gum, in the pocket between the tooth and gum, and is often linked to gum disease.
The pain and swelling come from pressure. As the infection grows, pus builds up with nowhere to escape, which presses on nearby nerves and causes the deep, throbbing ache that can spread to the ear, jaw, or neck. A foul or salty taste often means the abscess has started to drain. A fever can develop when the infection is more active.
While you arrange care
What helps with the pain meanwhile.
These steps ease pain and swelling while you arrange care. None of them treat the infection, so they buy comfort only and do not replace seeing a dentist. A cold compress on the outside of the cheek, about 15 to 20 minutes on and off, helps with swelling. Warm salt water rinses a few times a day soothe the area. Keeping your head raised reduces throbbing. Sip fluids, stick to soft foods, and use over the counter pain relief as directed on the label. Do not place aspirin directly against the gum, since it can burn the tissue, and never try to drain, cut, squeeze, or pop the swelling yourself.
Most people feel the pressure and pain begin to ease within a day or two of starting real treatment. If swelling, pain, or fever keeps getting worse, treat it as an emergency and use the warning signs above.
At the dentist
How a dentist treats an abscess.
The goal is to clear the infection by removing its source, not just to quiet the symptoms. The dentist usually drains the pus, often with a small cut to let it out, then rinses the area clean. The part that actually fixes the problem is removing the source, which is usually a root canal to clear the infection from inside the tooth, or an extraction if the tooth cannot be saved. Antibiotics are added only when the infection is spreading, when there is a fever, or for people at higher risk.
The key point is that antibiotics alone do not cure an abscess. They can slow the spread and buy time, but the tooth still has to be drained and then treated with a root canal or an extraction. Once a dentist sees the swelling, they can usually start treatment the same visit. See how a root canal clears an infected tooth.
Do not wait it out
If the swelling goes down, the infection is usually still there.
A tooth abscess does not heal on its own. Waiting tends to make treatment harder, lowers the chance of saving the tooth, and raises the odds of ending up in an emergency room. Sometimes the swelling or pain eases on its own because the abscess has burst and drained, which relieves the pressure for a while. That does not mean the infection is gone. The source is almost always still there and can flare again. The safe move is to be seen the same day, even if you feel better for the moment.
The exam to diagnose it is usually covered at or near 100 percent with a plan, and a plan that pays toward major work shares part of the root canal or extraction. See coverage that can start fast.
Questions
Tooth abscess questions.
A tooth abscess will not heal on its own, because the source of the infection inside or around the tooth remains until it is treated. Pain may ease for a while if the abscess drains, but the infection is usually still present and can return or worsen. A dentist treats the cause through procedures such as draining the infection, root canal treatment, or removing the tooth. Seeing a dentist promptly is the reliable way to resolve it.
Antibiotics alone do not cure a tooth abscess, because they cannot remove the infected tissue at the source. A dentist may prescribe antibiotics to help control a spreading infection, but dental treatment is still needed to fix the underlying problem. Relying only on antibiotics often lets the infection come back. Plan to see a dentist even if antibiotics make you feel better for a few days.
Go to the emergency room or call emergency services right away if you have trouble breathing or swallowing, swelling that is spreading to your eye, neck, or floor of the mouth, a high fever, or you feel very unwell. These can be signs that the infection is becoming dangerous. The ER can stabilize you and manage the infection, though you will still need a dentist for the tooth itself. When in doubt about severe symptoms, treat it as an emergency.
No, you should never try to drain or cut a tooth abscess at home. Doing so can spread the infection into deeper tissues, cause heavy bleeding, or lead to serious complications. Draining must be done by a dental or medical professional using sterile methods. If an abscess bursts on its own, rinse gently with warm salt water if a professional advises it, and still see a dentist promptly.
You should aim to see a dentist within about one day for an abscessed tooth, especially if you have swelling, fever, or significant pain. Dental infections can progress quickly, so sooner is better. If you cannot reach a dentist and your symptoms are getting worse, seek urgent medical care. Timing estimates are general guidance, and your own situation may call for faster care.
