Dental abscess treatment in Penrith.
A dental abscess at Bella Dental Penrith is treated with drainage of the pus, antibiotics if the infection has spread, and definitive treatment of the cause (root canal to save the tooth, or extraction if it cannot be saved). A dental abscess will not resolve on its own and can become serious if the swelling spreads to the face, jaw, or neck. We hold same-day emergency appointments for abscesses and provide antibiotics and pain relief while planning the next step.
What is a dental abscess?
A dental abscess is a pocket of pus caused by a bacterial infection in or around a tooth. There are 3 main types:
- Periapical abscess. The most common type. The infection starts inside the tooth (in the nerve) and spreads to the root tip and the surrounding bone.
- Periodontal abscess. The infection starts in the gum and bone around the root, often in a patient with existing gum disease.
- Gingival abscess. A localised infection in the gum, usually from a foreign body (a popcorn hull, a fish bone) stuck under the gum.
All three cause pain, swelling, and the risk of the infection spreading further.
What causes a dental abscess?
The most common causes:
- Untreated tooth decay that has reached the nerve
- Failed or incomplete root canal treatment
- A cracked tooth that has allowed bacteria into the nerve
- Advanced gum disease (periodontal abscess)
- A foreign body stuck under the gum (gingival abscess)
- Trauma that has killed the nerve, with infection developing later
What are the symptoms of a dental abscess?
The most common signs:
- Severe, throbbing toothache that may radiate to the jaw, ear, or neck
- Sensitivity to hot and cold (often with the tooth feeling better when cold water is held in the mouth)
- Pain on biting or chewing
- Swelling of the gum, face, or jaw
- A gum “boil” (small pimple) on the gum near the tooth, sometimes draining pus
- A persistent bad taste in the mouth or bad breath
- Fever and a general feeling of being unwell
- Swollen lymph nodes under the jaw or in the neck
- In severe cases, difficulty opening the mouth, swallowing, or breathing
If you have facial swelling that is spreading, a fever, or any difficulty breathing or swallowing, treat it as a medical emergency. Go to the emergency department of your nearest hospital, or call 000.
When should I see a dentist urgently for a dental abscess?
See a dentist the same day, if you have:
- A swollen face, jaw, or neck
- A fever
- Difficulty opening the mouth, swallowing, or breathing
- Severe throbbing pain that is not relieved by over-the-counter pain relief
- A draining gum boil with a bad taste
A dental abscess is one of the few dental problems that can become life-threatening if the infection spreads into the airway or the bloodstream. Do not wait for it to “settle down” on its own.
How is a dental abscess diagnosed?
At your emergency appointment we will:
- Ask about the pain and any recent dental symptoms
- Examine the tooth, the gum, and the face
- Test the tooth with cold and percussion
- Take an x-ray (periapical) to see the bone around the root
- Assess whether the swelling is localised or spreading
For complex cases, we may refer for a 3D CBCT scan or to an oral surgeon.
How is a dental abscess treated at Bella Dental Penrith?
Treatment happens in 3 steps:
Manage the infection.
Drain the pus, either through the tooth (during root canal) or through a small incision in the gum. Antibiotics are prescribed if the infection has spread beyond the local area, or if the patient is at higher risk (immunocompromised, diabetic). Antibiotics alone do not cure a dental abscess — they buy time until the cause is treated.
Treat the cause.
Either root canal treatment to save the tooth, or extraction if the tooth cannot be saved. The decision depends on how much of the tooth is left, the bone around the root, and your overall health.
Replace the tooth (if extracted).
Options are a dental implant, a bridge, or a partial denture.
We will give you a written treatment plan with item numbers and the cost of each step. We offer interest-free payment plans through Medipay.
How much does abscess treatment cost in Penrith?
Emergency appointment and x-ray;
$135 (often partly covered by health fund)
Antibiotics
$15 to $25 for a standard course
Root canal treatment (if the tooth can be saved)
$1,000 to $1,500
Crown (after root canal, on a back tooth)
$1,950 to $2,200
Extraction
$250 to $400 for a simple extraction, more for a surgical extraction
Implant (to replace an extracted tooth)
$4,000 to $6,000
The total depends on whether we save or extract the tooth, and which replacement option you choose.
Can a dental abscess go away on its own?
No. The infection does not resolve without treatment. Sometimes the pain and swelling settle temporarily when the abscess drains on its own, but the source of the infection is still there. It will flare up again, and the next flare can be worse.
A dental abscess is one of the few dental problems that can become life-threatening if ignored. The infection can spread to the airway (Ludwig’s angina) or the bloodstream (sepsis). Both are rare but serious.
How do I manage a dental abscess at home until my appointment?
Pain relief: paracetamol and ibuprofen together, taken as directed
Salt-water rinse: 1/2 teaspoon salt in a glass of warm water, swish and spit, 2 to 3 times a day
Cold compress: on the cheek for 15 to 20 minutes, 3 to 4 times a day
Soft diet: avoid the affected side
Sleep with the head elevated: extra pillow to reduce throbbing
Avoid smoking and alcohol
Take antibiotics as prescribed, if your dentist or GP has prescribed them
If the swelling is spreading, you have a fever, or you are having trouble breathing or swallowing, go to the emergency department immediately.

Questions We Get Often
Answers to Your Most Common Questions About Dental Care and Our Services
Still have a question?
Our team is ready to assist you with anything you need.
Is a dental abscess an emergency?
Yes. A dental abscess will not go away on its own and can become serious. Call us for a same-day emergency appointment, or go to the emergency department, if the swelling is spreading or you are having trouble breathing or swallowing.
Will antibiotics cure a dental abscess?
No. Antibiotics control the spread of the infection but do not remove the source. The cause (decay, dead nerve, gum disease) still has to be treated with root canal or extraction.
Can I pop a dental abscess at home?
No. Squeezing or cutting the gum at home risks pushing the infection deeper or into the bloodstream. We will drain it safely under local anaesthetic.
How long does a dental abscess take to heal?
Pain and swelling usually improve within 1 to 3 days of starting antibiotics and drainage. The tooth itself still needs root canal or extraction, and the gum heals fully within 1 to 2 weeks.
Can I prevent a dental abscess?
Most abscesses are preventable. Treat decay early with a filling, treat gum disease with regular cleans, see us promptly, if a tooth aches or is sensitive to hot, and book a 6-monthly check-up and clean.
