A dental abscess is a genuine infection, not just a bad toothache — and it needs treatment, not just painkillers. Here's how to recognise one, what causes it, and what to do next.
A dental abscess is a pocket of pus caused by a bacterial infection, usually starting inside a tooth or in the gum tissue around it. Unlike ordinary tooth sensitivity, it doesn't resolve with home remedies or over-the-counter painkillers alone — the infection needs to be drained and its source treated, or it can spread beyond the tooth.
This guide covers the two main types of dental abscess, what causes them, the symptoms to watch for, when it becomes a medical emergency, and how treatment actually works.
🦷 Periapical Abscess
Forms at the tip of a tooth's root, usually from decay or trauma that's allowed bacteria to reach the inner pulp.
🩸 Periodontal Abscess
Forms in the gum tissue beside a tooth, usually linked to advanced gum disease or trapped debris in a gum pocket.
Most abscesses trace back to bacteria finding a way into or around a tooth. Untreated tooth decay that's reached the inner pulp is the most common cause of a periapical abscess. A cracked or broken tooth can let bacteria in the same way. Advanced gum disease creates deep pockets where bacteria collect, leading to a periodontal abscess. Gum injury from something sharp, like a fish bone or food debris packed too deep to clean out, can also trigger one. Even a previous root canal that hasn't fully sealed the tooth can, in some cases, allow reinfection later on.
😣 Persistent, throbbing tooth pain
🔴 Swelling in the face, cheek or gum
🌡️ Fever or a general feeling of being unwell
🥴 A foul taste or bad breath from pus draining
🔵 A pimple-like bump on the gum
🍽️ Pain when chewing or touching the affected tooth
In rare cases, a dental infection can spread beyond the tooth and become dangerous. Seek emergency medical care immediately — not a routine dental appointment — if you notice:
Facial or neck swelling that's spreading or severe
Difficulty breathing or swallowing
High fever with feeling severely unwell
🩹
Drainage
A small incision releases the pus and relieves pressure, usually bringing quick relief from pain.
🩺
Root Canal Treatment
Removes the infected pulp inside the tooth and seals it, addressing the source of a periapical abscess.
💊
Antibiotics
Prescribed where the infection has spread beyond the immediate area, alongside — not instead of — drainage or the underlying dental treatment.
⚠️
Extraction
If the tooth is too damaged to save, removal clears the infection along with the source tooth.
🧼
Deep Cleaning
For a periodontal abscess linked to gum disease, thorough cleaning of the gum pocket is often part of treatment.
🔁
RCT Retreatment
If a previous root canal has become reinfected, retreatment addresses the underlying cause again.
👑
Restoration After Treatment
Once the infection is cleared, the tooth is often restored with a filling or crown to restore full function.
📋
Follow-Up Review
A follow-up visit confirms the infection has fully cleared and healing is on track.
Don't try to wait it out or rely on painkillers alone — an abscess doesn't resolve on its own, and delaying treatment risks the infection spreading. Don't attempt to drain it yourself; this needs to be done under proper clinical conditions to avoid pushing the infection deeper. And if you're prescribed antibiotics, they're generally meant to control the infection alongside dental treatment, not to replace the underlying procedure the tooth actually needs.
Get seen promptly at Dental Touch — we'll assess the infection, relieve the pressure, and treat the underlying cause so it doesn't come back.
Q1. Can a dental abscess go away without treatment?
No, not reliably. The infection may drain temporarily on its own or with antibiotics, but the underlying source — decay, a cracked tooth, or gum disease — remains and typically causes it to return.
Q2. Will antibiotics alone fix it?
Antibiotics can help control the spread of infection but generally don't remove the source. The tooth or gum area usually still needs direct treatment, such as drainage or a root canal.
Q3. Is a dental abscess dangerous?
Most are treatable without complication, but in rare cases the infection can spread to the face, jaw or beyond, which can become serious. Facial swelling, difficulty breathing or swallowing, or a high fever need urgent medical attention.
Q4. Does draining an abscess hurt?
The procedure is done under local anaesthesia, and most patients feel significant relief once the pressure from the built-up pus is released.
Q5. Can I prevent a dental abscess?
Regular checkups, prompt treatment of cavities, and good gum health go a long way — most abscesses trace back to decay or gum disease that had time to progress unnoticed.
