Dental abscess
What it is
An abscess forms when infection collects at the tip of a tooth root or in the gum. It will not go away without treatment of the cause.
Common symptoms
- Severe, throbbing pain
- Swelling of gum or face
- A gum boil or pimple
- Bad taste
- Fever or feeling unwell
Possible causes
- Untreated decay
- Cracked tooth
- Advanced gum disease
When to seek care
Contact a dentist as soon as possible.
Swelling spreading to the eye, neck or floor of the mouth, difficulty breathing or swallowing, or high fever needs urgent medical care (hospital emergency department).
What treatment may involve
Draining the infection and treating the cause — usually root canal treatment or extraction. Antibiotics may be needed in some cases.
Your dentist will assess, relieve pressure where appropriate and plan definitive treatment.
What it may feel like & recovery
Relief often comes once pressure is released. The area is numbed for treatment.
Most people improve within a few days of treatment. Complete the treatment plan so the infection does not return.
An abscess needs professional care. Swelling can reduce temporarily but the infection usually remains until the cause is treated.
