Emergency assessment
Swelling often needs prompt review to identify the source and whether infection risk is increasing.
Facial or gum swelling
Swelling in the gum, face or jaw may be linked with dental infection and should be treated as urgent, especially with fever or spreading pain.

My gum, face or jaw is swollen. Is this urgent?
Swelling can indicate inflammation or infection around a tooth, gum or jaw. Because infection can change quickly, swelling should be taken seriously, especially if it is spreading or associated with fever, severe pain or feeling unwell.
What you may be worried about
- The swelling may be caused by an infection or abscess.
- The problem may spread or become harder to manage.
- You may not know whether antibiotics, dental treatment or medical care is needed.
- The tooth causing the swelling may or may not be saveable.
Possible causes
- Infection from a tooth nerve, deep decay or a cracked tooth.
- Gum infection or food trapping around a tooth or wisdom tooth.
- An abscess draining through the gum.
- Trauma, irritation or inflammation around existing dental work.
When to treat this as urgent
Urgency level: emergency
- Swelling in the face, jaw, gum or under the tongue.
- Fever, feeling unwell, or pain that is spreading.
- Difficulty swallowing, breathing or opening your mouth.
- Swelling that is getting worse quickly.
- A bad taste, pus, or a pimple-like swelling on the gum.
What to do now
- Start the urgent assessment pathway if swelling involves the gum, face, jaw, or under the tongue.
- Seek medical emergency care now if breathing, swallowing, opening your mouth, or general wellness is affected.
- Note when swelling started, whether it is spreading, and whether fever or a bad taste is present.
What to avoid
- Do not try to drain swelling yourself.
- Do not wait for swelling to become painful before asking for help.
- Do not rely on antibiotics alone without identifying the dental source.
When to arrange a dental assessment
- Swelling should be assessed promptly, especially if it is spreading, painful, recurrent, or linked with fever.
What a dentist may need to assess
- The source of infection, the involved tooth or gum area, spread of swelling, X-ray changes, and whether medical escalation is needed.
Options that may be considered
Treating the source
Depending on the cause, treatment may involve drainage, root canal treatment, extraction, gum care or other management.
Medication when appropriate
Medication may sometimes be part of care, but it does not always remove the source of a dental infection.
Medical escalation
Severe or spreading swelling, difficulty swallowing or breathing, or systemic illness may require urgent medical care.
What we would consider before recommending treatment
- Where the swelling is and whether it is spreading.
- Whether there are fever, breathing, swallowing or mouth-opening concerns.
- Which tooth or gum area is the likely source.
- Whether the tooth can be predictably treated.
- Whether the safest pathway is dental care, medical care or both.
If it were our own teeth
If it were our own mouth, we would not ignore facial, gum or jaw swelling. We would want to know the source and whether the infection risk is increasing before deciding on treatment.
A sensible next step
Start the emergency assessment if there is swelling in the gum, face or jaw, especially with fever, severe pain, spreading discomfort or feeling unwell.
Possible next steps
- Drainage, root canal treatment, extraction, gum treatment, medication, medical referral, or review may be discussed depending on severity.
Choosing the next step
Use the emergency pathway only when the problem may need urgent review.
For routine, planned, or unclear but non-urgent concerns, book a normal appointment. For swelling, trauma, severe pain, bleeding, or a broken tooth that cannot wait, use the emergency assessment instead.
Common questions
Is gum swelling always an emergency?
Not always, but swelling can indicate infection and should be assessed promptly, especially if it is worsening, painful or associated with fever.
Will antibiotics fix dental swelling?
Antibiotics may sometimes be used, but dental swelling often needs the source of infection identified and treated.
When should swelling be treated as medically urgent?
Difficulty breathing, swallowing, opening the mouth, rapidly spreading swelling or feeling very unwell should be treated as urgent.
