Dental Infection and Swelling in East Brisbane
If you have facial swelling, gum swelling, pressure, pus, fever or a bad taste, it may be a sign of dental infection. These symptoms should not be ignored, especially if swelling is increasing or spreading.
Short Answer
A dental infection may cause toothache, gum swelling, facial swelling, pressure, pus, bad taste, fever or pain when biting. It often needs dental assessment because the source may be inside the tooth, around the gum or under the bone.
If swelling affects breathing or swallowing, spreads toward the eye, neck or throat, or you feel seriously unwell, seek hospital emergency care immediately.
When Is Dental Swelling Urgent?
Swelling is one of the most important dental symptoms to take seriously. It can be localised around the gum, or it can spread into the face, jaw, neck or throat.
Call a dentist urgently if
- You have gum or facial swelling
- You notice pus or a bad taste
- There is throbbing pain or pressure
- The tooth hurts when biting
- Symptoms are worsening
Seek hospital care if
- Breathing or swallowing is affected
- Swelling is spreading quickly
- Swelling involves the eye, neck or throat
- You feel very unwell, faint or confused
- There is severe fever or serious illness symptoms
If you are unsure
Phone our team and describe the swelling, where it is, how fast it is changing and whether you feel unwell. We can guide you on whether dental or medical care may be more appropriate first.
When a Dental Appointment May Not Be Suitable First
If swelling affects breathing or swallowing, there is major facial trauma, uncontrolled bleeding, chest pain, fainting, severe fever, confusion, or serious illness symptoms, hospital emergency care may be more appropriate first. Dental assessment can then follow once the immediate medical risk is managed.
Common Signs of a Dental Infection
Dental infections can present in different ways. Some are painful, while others may start as pressure, swelling or a small gum bump.
Facial swelling
Swelling in the cheek, jaw or under the eye may suggest infection is spreading beyond the tooth or gum area. This should be assessed promptly.
Gum swelling or abscess
A swollen gum, pimple-like bump, pus or bad taste can indicate an abscess or draining infection.
Throbbing tooth pain
Throbbing pain, pain when lying down or pain when biting may be linked with pressure from infection or inflammation around the tooth root.
Fever or feeling unwell
Feeling unwell with dental swelling can be a warning sign that the infection needs urgent attention.
Bad taste or pus
Pus, a bad taste or fluid from the gum may mean infection is draining. The source still needs assessment and treatment.
Difficulty opening the mouth
Limited mouth opening with swelling or pain may indicate a more serious infection pattern and should be checked quickly.
What Causes Dental Infection or Swelling?
A dental infection usually starts from a source that needs treatment. Antibiotics alone may not fix the cause if the infection is coming from a tooth, gum pocket or trapped infection.
Infected tooth nerve
Deep decay, cracks or trauma can allow bacteria to reach the nerve space inside the tooth. This may lead to pain, pressure or an abscess. You can learn more about tooth decay and dental caries.
Gum infection
Deep gum pockets, gum disease or trapped debris around a tooth can cause swelling, bleeding, pus or tenderness. If gum health is involved, our gum disease treatment page may help.
Wisdom tooth infection
Partly erupted wisdom teeth can trap food and bacteria, causing pain, swelling, bad taste and difficulty opening the mouth.
Cracked or broken tooth
A crack or fracture can allow bacteria to enter deeper areas of the tooth, leading to inflammation or infection. If the tooth has chipped or fractured, read our broken tooth guide.
What to Do Before Your Appointment
Helpful steps
- Call for urgent advice if swelling is present
- Rinse gently with warm salty water if comfortable

Important safety note
If swelling affects breathing or swallowing, spreads rapidly, or involves the eye, neck or throat, seek hospital emergency care immediately.
How We Assess Dental Infection
Our first goal is to identify the source of infection, check for safety concerns and explain the most appropriate next step.
1. Symptom history
We ask when swelling started, whether it is spreading, pain triggers, fever symptoms and relevant medical history.
2. Clinical examination
We check the tooth, gum, swelling, bite, abscess signs and surrounding tissues.
3. X-rays if needed
X-rays may help identify infection around tooth roots, deep decay, bone changes or wisdom tooth problems.
4. Source control
Treatment may involve drainage where appropriate, stabilising the tooth, root canal treatment, tooth removal or other care depending on the cause.
5. Medication decisions
Antibiotics are not always required. If they are appropriate, they are usually part of a broader plan to manage the source of infection. You can read more about antibiotics for dental infections.
6. Follow-up plan
Some infections need review or definitive treatment after the urgent symptoms are controlled.
Possible Treatment Options
The right treatment depends on whether the infection is coming from the tooth nerve, gum, wisdom tooth area or another source.
Root canal treatment
If the infection is coming from inside the tooth and the tooth can be saved, root canal treatment may be discussed. You may also find our article on the true value of a root canal helpful.
Drainage or stabilisation
In some cases, draining pressure or stabilising the area may help control urgent symptoms before definitive treatment.
Tooth removal if needed
If a tooth cannot be saved, tooth removal may be discussed, along with future replacement options if relevant.
Gum or wisdom tooth care
If infection is related to the gum or a wisdom tooth area, treatment depends on the position, cleaning access and whether symptoms keep returning.

Dental Infection FAQs
Is facial swelling from a tooth an emergency?
It can be. Facial swelling may indicate infection and should be assessed urgently, especially if it is increasing or spreading.
Should I go to hospital for dental swelling?
Go to hospital urgently if swelling affects breathing or swallowing, spreads toward the eye, neck or throat, or you feel seriously unwell.
Can antibiotics fix a dental infection?
Not always. Many dental infections need treatment at the source. You can read more about antibiotics for dental infections.
What causes a bad taste with swelling?
A bad taste may be linked with pus or drainage from an abscess. If bad breath or taste is ongoing, our bad breath treatment page may also help.
Can a dental abscess go away by itself?
Symptoms may settle temporarily, but the source often remains. Delaying care can allow the infection to return or worsen.
What if I have swelling but no pain?
Swelling without pain can still be important. Some infections drain or spread with less pain, so it is safest to arrange assessment.
