Tooth Abscess Treatment: How the Infection Is Cleared

What a Tooth Abscess Actually Is
An abscess is a pocket of pus from a bacterial infection. With a tooth, it usually starts when bacteria reach the pulp (the nerve inside the tooth) through a deep cavity, a crack, or a filling that has failed, and the infection spreads out of the root tip into the bone and gum. The body walls it off, and that walled-off pocket is the abscess.
It shows up in a few ways: a deep, throbbing ache, a tooth that's sore to bite on, a pimple-like bump on the gum that may leak a salty or bad taste, and sometimes a swollen cheek or jaw. Our guide to a tooth abscess covers how to recognise one. The pain can ease for a while if the pocket drains on its own through that gum bump, but the infection is still there. It doesn't heal without treatment.
How a Tooth Abscess Is Treated
Treatment does two things: it drains the pus and it removes the source of the infection. Draining releases the pressure, which is what takes most of the pain away. Removing the source is what stops it coming back, and there are two ways to do that:
- A root canal, to save the tooth. The infected pulp is cleaned out of the canals inside the root, the space is disinfected and sealed, and the tooth stays in your mouth. This is the usual route when the tooth is still sound enough to keep. Our page on an emergency root canal walks through it.
- An extraction, to remove the tooth. If the tooth is too broken down or cracked to save, taking it out clears the infection with it. We'll tell you honestly which side of that line your tooth is on rather than push a root canal that won't hold; our guide to a root canal versus an extraction lays out the trade-off.
Antibiotics often come alongside treatment, especially when the face is swollen, but they are not the treatment. They can bring the swelling down and buy time, yet they can't reach an infection sealed inside a tooth, so the pain and the abscess return once the course ends. Our guide on why antibiotics alone don't cure a tooth infection explains why the tooth itself still has to be opened.
What the Visit Looks Like
The first step is getting you numb and comfortable, then an X-ray to see where the infection sits and how much bone it has affected. From there we drain the abscess and start clearing the source, either opening the tooth to clean out the pulp or removing the tooth. Draining and opening the tooth is usually what settles the pain, often the same day, even when the root canal is finished at a follow-up visit.
If you're bracing for the worst, it's usually not what the reputation suggests. A patient we'll call Mrs. Esther had a root canal here and asked us to pass on her thanks afterward; her mother, a dentist herself, saw the photos from the procedure and was impressed with the work. People walk in expecting the horror story and are surprised. The tooth almost always hurts more before treatment than during it, because clearing the infection is what relieves the pain.
What to Do Until You're Seen
An abscess needs treating, but you can take the edge off while you arrange to be seen:
- Take an over-the-counter painkiller you normally tolerate, at the dose on the packet. Our guide to painkillers for a toothache covers what tends to help.
- Use a cold compress on the outside of the cheek for swelling. Cold, not heat, since warmth encourages an infection to spread.
- Rinse gently with warm salt water a few times a day. If the gum bump is draining, this keeps the area clean.
- Keep your head propped up, including at night, since lying flat makes the throbbing worse.
Don't try to pop or squeeze the gum bump, and don't hold an aspirin against it, which burns the gum and does nothing for the tooth. And don't read the pain fading as the problem going away. With an abscess, quiet usually means the pocket has drained a little, not that the infection has cleared.
An Abscess Won't Wait It Out
Waiting to see whether an abscess settles on its own is usually the more expensive choice, not the cheaper one. The infection doesn't resolve without the tooth being treated, and left long enough it spreads through the bone, which can turn a tooth a root canal could have saved into an extraction, and then you're paying to replace the tooth as well. Dealing with it early is what keeps the tooth in the save-it column. Our guide on how far a tooth infection can spread covers why it isn't something to sit on.
When It's a Hospital Emergency, Not a Dental One
Most abscesses are miserable but safe to treat in a dental chair over the next day or two. A small number are not, and these belong in a hospital emergency room, not here. Go straight to a hospital if you have:
- Swelling spreading up toward your eye, or down into your neck.
- Any difficulty breathing or swallowing, or a change in your voice.
- Swelling on the floor of the mouth that is pushing your tongue up.
- A high fever with chills, or feeling seriously unwell with it.
Those signs mean the infection is moving into spaces where it can threaten the airway, and a hospital can give intravenous antibiotics and manage it in a way a clinic cannot. It's rare, but it's exactly why an abscess isn't something to leave for weeks. Our guide to facial swelling from a tooth infection walks through where that line sits.
Getting Seen in English in Beit Shemesh
If your Hebrew is fine for the shops but not for words like abscess, drainage, and root canal, you can do the whole visit in English here. Dr. Joel trained and qualified in the United States, so telling us what the tooth has been doing, hearing whether it can be saved, and asking whatever you want to ask all happen in a language you're comfortable in. When you're in pain and trying to decide fast, not having to translate for yourself is a real relief.
We're in Ramat Beit Shemesh and see patients from across the wider area, not only local residents, and you don't need to be registered with us in advance.
If you have a tooth that's throbbing, sore to bite on, or a bump on the gum with a bad taste, call or WhatsApp us at 055-985-8845 and send a photo if you can. We'll tell you how soon you need to be seen, give you the cost before anything starts, and if it can safely wait, we'll say so. We're in Ramat Beit Shemesh, open Sunday to Thursday 8:00 AM to 8:00 PM and Friday 8:00 AM to 2:00 PM, with after-hours emergency treatment outside those hours. Our dental infection treatment, emergency dentist, and root canal pages explain how we handle urgent visits.
For guidance from sources with nothing to sell, the ADA's MouthHealthy explains what a dental abscess is, and the American Association of Endodontists covers root canal treatment and the symptoms of an infected tooth.
