Short answer A tooth abscess is treated by removing the source of infection: the dentist drains the pus and then either cleans the inside of the tooth with root canal treatment or removes the tooth. Antibiotics alone do not cure an abscess; they are only added when infection is spreading or you feel unwell. Facial swelling that spreads, fever, or trouble swallowing or breathing needs hospital care the same day. Medically reviewed by [Prof. Nouran Abdel Nabi](https://elnabidentalclinic.com/en/dr-nouran-abdel-nabi/) · Last reviewed 19 October 2026 A tooth abscess (خراج الأسنان) is a pocket of pus caused by bacteria, usually from a dead or badly decayed tooth or from deep gum disease. It does not heal on its own, even when the pain suddenly stops. **The cure is to remove the source of the infection**: drain the pus, then either save the tooth with root canal treatment or take it out. Antibiotics can help in specific situations, but they do not reach the bacteria living inside a dead tooth, so on their own they only buy time. If you are reading this with a throbbing tooth or a swollen face, start with the red flags below. Then read on to understand your options calmly. ## When is a tooth abscess an emergency? Most abscesses need a dentist within a day or two. Some need a hospital emergency department **today**. Go to the nearest hospital emergency department (do not drive yourself) if you have any of these: - Swelling that is spreading quickly across the face, towards the eye, or down into the neck. - Difficulty breathing, swallowing or speaking, or swelling under the tongue or in the floor of the mouth. - You cannot open your mouth more than a finger's width. - A swollen or painful eye, or changes in your eyesight. - High fever, shivering, or feeling very unwell, confused or faint. These signs mean the infection may be spreading into the tissues of the face and neck, which can threaten the airway. UK guidance for dentists treats them as hospital emergencies, and the [NHS dental abscess page](https://www.nhs.uk/conditions/dental-abscess/) gives the same advice to patients. People with diabetes, a weakened immune system, or on chemotherapy or steroids should seek help sooner rather than later. ## Symptoms of a tooth abscess - Intense, throbbing toothache that can spread to the ear, jaw or neck, often worse when lying down. - Pain when biting, or a feeling that the tooth is "high". - A swollen, red gum, sometimes with a small pimple-like bump that leaks a salty or bad-tasting fluid. - A swollen cheek or jaw, and tender glands under the jaw. - Bad taste or bad breath, and sometimes a raised temperature. ### Tooth abscess vs gum abscess (خراج اللثة) A **tooth (periapical) abscess** starts at the tip of the root of a tooth whose nerve has died, usually from deep decay, a crack or an old injury. A **gum (periodontal) abscess** starts in a deep pocket between the gum and the root, usually in someone with gum disease, and the tooth may still be alive. The treatments differ, which is why an X-ray and a proper examination matter before anything is done. ## How a dentist treats a tooth abscess 1. **Examination and X-ray** to find which tooth is the source and how much bone is affected. 2. **Drainage** under local anaesthetic, either by opening the tooth or by a small cut in the swollen gum. Relief is often felt within hours once the pressure is released. 3. **Removing the source**, usually by one of three routes: - **Root canal treatment** to clean, disinfect and seal the inside of the tooth, so you keep it. Back teeth usually then need a crown. - **Deep cleaning of the gum pocket** for a gum abscess, followed by gum treatment. - **Extraction** when the tooth is too broken down or cracked to save. 4. **Review** to confirm the swelling has settled and plan the final restoration or replacement. If you are worried about root canal treatment itself, our page on [whether root canal treatment is painful](https://elnabidentalclinic.com/en/faq/is-root-canal-treatment-painful/) explains what it actually feels like. Details of the procedure are on our [root canal treatment](https://elnabidentalclinic.com/en/services/root-canal/) page. ## Do antibiotics cure a tooth abscess? No, not on their own. This is one of the most common misunderstandings in Egypt, where many people take a course of antibiotics from a pharmacy, feel better, and assume the problem is solved. The swelling settles, but the dead tissue inside the tooth is still there, and the abscess very often returns, sometimes larger. Current dental prescribing guidance says abscesses should be treated first by drainage and removing the cause. Antibiotics are added when: - the infection is spreading (facial swelling, swollen glands), or - you have general symptoms such as fever or feeling unwell, or - drainage cannot be done straight away. When antibiotics are needed, the dentist or doctor chooses the medicine and the duration based on your health, allergies and other medicines. Please do not take leftover antibiotics or ones recommended by a friend, and finish exactly the course you were prescribed. Unnecessary antibiotics also add to antibiotic resistance, which makes future infections harder to treat. ## What can I do at home until I see the dentist? Home measures can make you more comfortable, but they do not treat the abscess. An over-the-counter painkiller taken exactly as the pack label says (ask a pharmacist which one suits you, especially if you are pregnant, have a medical condition or take other medicines), soft lukewarm food on the other side, gentle brushing and sleeping with your head raised can help until your appointment. Children under 16 should not take aspirin. Our guide to [toothache at night](https://elnabidentalclinic.com/en/faq/tooth-pain-at-night-relief/) covers safe temporary relief step by step. ### What not to do - Do not put aspirin, garlic or strong chemicals directly on the gum; they can burn it. - Do not put a hot compress on a swollen face; dentists generally advise against heat on a dental swelling. - Do not try to pop or cut the swelling yourself. - Do not ignore an abscess because the pain has stopped; that can mean the nerve has died, not that the infection has gone. ## Can the tooth be saved? Often, yes. If enough healthy tooth remains and the root and surrounding bone are in reasonable condition, root canal treatment followed by a crown keeps the tooth working for many years in most cases. Saving a natural tooth is usually simpler and cheaper over time than extracting and replacing it. A tooth may not be worth saving if it is split, decayed below the gum line, or very loose from bone loss. In that case, extraction is the honest recommendation, and the gap can later be restored with an implant, a bridge or a partial denture once the area heals. See [implants vs bridge vs denture](https://elnabidentalclinic.com/en/faq/implants-vs-bridge-vs-denture/) for how those compare. ## How Prof. Nouran approaches an abscessed tooth When you are in pain, the last thing you want is to be rushed into a decision or handed a prescription without an explanation. Prof. Nouran examines you personally, reviews the X-ray with you, and explains whether the tooth can realistically be saved, what each option involves, and what it will cost before treatment starts. Because she is a Professor of Prosthodontics, she also thinks about the tooth's future: whether it will hold a crown well, and, if it must come out, how the space will be replaced so you can chew and smile comfortably.
