An abscess is a painful pocket of pus that forms when your body fights off an infection. You can treat it effectively, but the core treatment is always the same: the pus needs to be drained. For small abscesses, warm compresses may help them drain on their own. For larger or deeper ones, a doctor must make a small cut to drain the pus, and you will likely need antibiotics if the infection is spreading.
What Exactly Is an Abscess?
An abscess is your body’s way of walling off an infection. When bacteria get under your skin, your immune system sends white blood cells to fight them. These cells, along with dead tissue and bacteria, collect and form pus. The body builds a wall around this pus to keep the infection from spreading.
You can get an abscess almost anywhere on your body. Common spots include the skin, under a tooth, in the gums, at the base of a hair follicle, or around a foreign object like a splinter. A boil is a type of skin abscess that starts in a hair follicle.
The area becomes swollen, red, warm, and very tender. You may also feel a throbbing pain. Some people develop a fever, which means the infection is more serious.
How Can You Treat an Abscess at Home?
Only small, superficial abscesses are suitable for home care. If the abscess is larger than half an inch across, or if it is on your face, spine, or groin, see a doctor. Do not attempt to manage those at home.
For a small, surface-level abscess, the main home treatment is a warm compress. Soak a clean cloth in warm water, wring it out, and hold it against the area for 15 to 20 minutes. Do this three to four times a day. The heat increases blood flow to the area, which can help the body push the pus closer to the surface so it can drain on its own.
Keep the area clean and covered with a sterile bandage. Wash your hands before and after touching the area. If it drains on its own, continue using warm compresses and keep the wound covered until it heals completely.
There is one critical rule: never squeeze or pop an abscess yourself. Pressing on it can push bacteria deeper into your tissues or into your bloodstream. This can turn a local infection into a much more dangerous one, like sepsis.
When Do You Need a Doctor for an Abscess?
You should see a doctor if the abscess is large, deep, or getting bigger. You also need medical care if the pain is severe or if the area is very red or has red streaks spreading outward.
Red streaks are a sign the infection is moving beyond the abscess wall. A fever, chills, or feeling generally unwell are other warning signs. If you have diabetes, a weakened immune system, or poor circulation, see a doctor for any abscess, even a small one.
An abscess that does not improve after two days of warm compresses also needs medical evaluation. An abscess on your face, especially near your nose or eyes, requires urgent medical attention because infections there can spread to the brain.
What Does a Doctor Do to Treat an Abscess?
The standard medical treatment for an abscess is called incision and drainage. The doctor numbs the area with a local anesthetic, makes a small cut with a scalpel, and lets the pus drain out. After draining, they may pack the wound with sterile gauze to keep it open so it can continue draining over the next day or two.
This procedure is quick and usually gives immediate relief from the pressure and pain. It is the single most effective treatment for an abscess. Antibiotics alone cannot cure an abscess because the pus is walled off from your bloodstream, so oral antibiotics cannot reach the infection in high enough concentration.
After drainage, the doctor may or may not prescribe antibiotics. For a simple skin abscess in a healthy person, antibiotics are often not needed after proper drainage. However, antibiotics are usually prescribed if you have a weakened immune system, if the infection is spreading, if you have a fever, or if the abscess is in a high-risk area like the face or hands.
How Do You Treat a Tooth Abscess?
A tooth abscess is a dental emergency. It forms inside the tooth or in the gums and can cause severe, throbbing pain. Home treatment for a tooth abscess is limited to pain relief while you arrange to see a dentist.
Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage the pain. Rinsing your mouth with warm salt water several times a day may provide some temporary relief, but it will not cure the infection.
A tooth abscess requires professional dental treatment. The dentist will need to drain the pus, perform a root canal to remove the infected pulp, or in severe cases, extract the tooth. You will almost certainly need antibiotics for a tooth abscess because the infection can spread to your jaw, face, or bloodstream. Do not wait for a tooth abscess to resolve on its own — it will not.
What Happens if an Abscess Is Left Untreated?
An untreated abscess will not simply go away on its own in most cases. It can continue to grow, become more painful, and the infection can spread to surrounding tissues. This can lead to cellulitis, a deeper and more widespread skin infection.
In serious cases, the infection can enter your bloodstream. This condition, called bacteremia, can progress to sepsis, which is a life-threatening whole-body response to infection. Sepsis requires immediate hospital treatment with intravenous antibiotics and fluids.
Other complications depend on the location. An untreated tooth abscess can spread to the jaw bone or sinuses. An abscess near the spine can press on nerves. The bottom line is that an abscess is an active infection, and infections do not resolve without intervention.
How Can You Prevent an Abscess?
Prevention focuses on keeping bacteria out of your skin. Clean any cuts, scrapes, or punctures immediately with soap and water. Apply an antibiotic ointment and cover with a sterile bandage until the wound closes.
Do not share personal items like razors, towels, or washcloths. These can carry bacteria from one person’s skin to another. Good hand hygiene is one of the most effective ways to prevent skin infections.
If you have diabetes, keeping your blood sugar under control reduces your risk of infections, including abscesses. High blood sugar impairs immune function and slows wound healing. People with diabetes are also more likely to develop abscesses in areas of poor circulation.
If you notice a small, tender bump forming, start warm compresses early. This may help the body resolve it before it becomes a full abscess that requires drainage.
Frequently Asked Questions
Can you drain an abscess at home?
No. You should never attempt to drain an abscess at home by squeezing or cutting it. This can push bacteria deeper into your tissues and cause a serious bloodstream infection.
How long does an abscess take to heal after drainage?
Most abscesses heal within one to two weeks after professional drainage. The wound may need daily dressing changes and should be kept clean and covered until it closes.
Do you always need antibiotics for an abscess?
No. After proper drainage, a healthy person with a simple skin abscess often does not need antibiotics. Antibiotics are needed when the infection is spreading, you have a fever, or you have a weakened immune system.
Will a warm compress make an abscess go away?
For a small, superficial abscess, warm compresses can help it drain on its own. For larger or deeper abscesses, warm compresses are not enough and professional drainage is required.
