A painful and potentially serious dental condition characterized by a collection of pus that forms in a localized area within or around a tooth.
A dental abscess is a painful oral condition in which a pocket of pus forms inside the tooth, at the root, or within the surrounding gum tissue. It is almost always caused by a bacterial infection and should be treated promptly to prevent serious complications.
What Is a Dental Abscess?
A dental abscess develops when bacteria invade the soft tissue inside a tooth or the gum area around it. There are two main types:
- Periapical abscess — occurs at the tip of the tooth’s root, usually because of untreated tooth decay or trauma that allows bacteria into the pulp.
- Periodontal abscess — forms in the gums beside the tooth, often associated with gum disease, injury, or trapped food debris.
Both types involve a buildup of pus, inflammation, and pressure that can lead to significant pain.
Why Prompt Treatment Matters
If left untreated, the infection can spread beyond the tooth and gums into the jaw, face, neck, or even the bloodstream. In severe cases, this can become life-threatening. Early dental care is essential to stop the infection, relieve pain, and prevent complications.
A dentist may recommend:
- Draining the abscess
- Antibiotics
- Root canal treatment
- Tooth extraction (if the tooth cannot be saved)
- Treatment for gum disease or decay
Symptoms of a Dental Abscess
The signs of an abscess can vary, but common symptoms include:
- Severe, throbbing toothache Pain may come on suddenly or gradually worsen and can radiate to the ear, jaw, or neck.
- Swelling of the face, cheek, or jaw The swelling may be noticeable and may feel warm or tender to the touch.
- Pain when chewing or biting Pressure on the affected tooth often intensifies pain.
- Fever The body may develop a low-grade fever as it attempts to fight off the infection.
- Sensitivity to hot or cold The affected tooth may react strongly to temperature changes.
- Bad taste or foul smell Pus and bacteria can create an unpleasant taste or odour in the mouth.
- Red, swollen gums In periodontal abscesses, the gums may be tender, inflamed, and visibly swollen.
- Draining pus If the abscess ruptures, pus may leak into the mouth, offering temporary relief but not resolving the infection.
When to Seek Help
Anyone experiencing symptoms of a dental abscess should seek immediate dental care. Early treatment protects both oral health and overall health, preventing the infection from spreading further.
