⚠️ WHEN TO GO TO EMERGENCY DEPARTMENT — NOT THE DENTIST: If your tooth infection causes facial swelling spreading to the jaw, neck or eye, difficulty swallowing or breathing, severe lockjaw or fever above 38°C — go to your nearest emergency department immediately. A spreading dental infection can become life-threatening within hours. Do not wait for a dental appointment.

A tooth infection, also called a dental abscess, is a localised collection of pus — dead white blood cells, bacteria and tissue fluid — that forms as your immune system attempts to wall off a bacterial infection. Unlike most infections in the body, a dental abscess cannot drain and resolve on its own. Without treatment, the infection grows, spreads into surrounding bone and soft tissue, and can eventually reach the jaw, neck and airway.
Dental abscesses are among the most common dental emergencies seen in Australian emergency departments. An untreated dental abscess can be life-threatening — Ludwig’s angina (a spreading floor-of-mouth infection) and descending mediastinitis (infection spreading down into the chest) are rare but documented complications. Early dental treatment prevents this escalation entirely.
Paynless Dental provides same-day emergency assessment and treatment for tooth infections at all three Sydney clinics. Call (02) 8677 9094 now. If you have facial swelling, difficulty swallowing or fever — go to your nearest emergency department immediately.
For independent clinical information on dental abscess:
| Type | Where It Forms | Primary Cause | Treatment |
|---|---|---|---|
| Periapical Abscess | At the tip of the tooth root — inside the jawbone | Untreated decay reaching the nerve · failed root canal | Root canal treatment or extraction · antibiotics if spreading |
| Periodontal Abscess | In the gum alongside the tooth root · within the periodontal pocket | Advanced gum disease · food impaction in deep pocket | Periodontal drainage · deep clean · antibiotics · extraction if severe |
| Pericoronal Abscess | Around the crown of a partially erupted tooth (often wisdom tooth) | Food and bacteria trapped under the gum flap (operculum) | Irrigation · antibiotics · wisdom tooth extraction once resolved |
| Combined Endo-Perio Abscess | Involving both the root tip and the gum — more complex | Long-standing infection affecting both pulp and periodontium | Combination of root canal and periodontal treatment · sometimes extraction |
A periapical abscess is the most common type — caused by deep decay that infects the pulp, killing the nerve and allowing bacteria to accumulate at the root tip. Digital X-rays at Paynless Dental confirm the type and extent before treatment planning. Call (02) 8677 9094.
⚠️ A recurring pimple on the gum that drains and returns is a chronic abscess — the infection is active. The absence of severe pain does not mean the infection has resolved. Without treatment, bone destruction continues silently. Call Paynless Dental (02) 8677 9094.
| Stage | What Is Happening | Action Required |
|---|---|---|
| Stage 1 — Pulpitis | Nerve inflamed — throbbing toothache · sensitivity to hot/cold | 📞 Call dentist — root canal may save the tooth |
| Stage 2 — Pulp Necrosis | Nerve dies — pain may temporarily reduce · bacteria multiply at root tip | 📞 Call dentist — silent infection continues even without pain |
| Stage 3 — Periapical Abscess | Pus accumulates at root tip · severe pain · possible fistula on gum | 📞 Call dentist urgently — same day |
| Stage 4 — Spreading Cellulitis | Infection breaks through bone into soft tissue · facial swelling · fever | ⚠️ Emergency department — urgent IV antibiotics |
| Stage 5 — Ludwig’s Angina / Mediastinitis | Infection spreads to floor of mouth, neck, chest — airway at risk | ⚠️ Hospital emergency — life-threatening |
Most dental infections never reach Stage 4 or 5 — because patients seek treatment at Stage 2 or 3. The key is not waiting. Call Paynless Dental on (02) 8677 9094 the moment you notice symptoms.
About antibiotics and dental abscesses: A very common misconception is that antibiotics will cure a tooth infection. They will not. Antibiotics reduce the bacterial load and systemic spread — but the source of infection (the necrotic pulp or periodontal pocket) must be treated to achieve a cure. A tooth infection treated with antibiotics alone will recur. The definitive treatment is root canal or extraction. Call Paynless Dental (02) 8677 9094.

Direct answers to the questions Sydney patients most commonly ask about dental abscesses and tooth infection — symptoms, spreading, antibiotics, treatment, cost and when to go to hospital.
A dental abscess is a pocket of pus caused by bacterial infection — either at the root tip of the tooth (periapical abscess) or in the gum alongside the root (periodontal abscess). It is caused by untreated decay reaching the nerve, advanced gum disease, dental trauma or a failed previous root canal. A dental abscess will not resolve on its own and requires dental treatment — antibiotics alone are not a cure. Call Paynless Dental (02) 8677 9094. See Healthdirect — Tooth Abscess.
Severe, constant throbbing toothache — often worsening when lying down. Swelling of the gum or face. Pimple-like bump on the gum (fistula). Persistent bad taste or smell from the mouth. Tooth sensitivity to pressure. Fever. Pain radiating to the jaw, ear or neck. Go to your nearest emergency department immediately if swelling is spreading, you have difficulty swallowing or breathing, or fever above 38°C — these indicate a life-threatening spreading infection.
No — antibiotics will not cure a tooth infection. They reduce bacterial spread and systemic symptoms temporarily, but the source of infection — the necrotic pulp or infected periodontal pocket — must be treated to achieve a cure. A dental abscess treated with antibiotics alone will recur, often more severely. Antibiotics are used in conjunction with root canal treatment, drainage or extraction — not instead of them. Call Paynless Dental (02) 8677 9094 for definitive treatment.
Yes — rarely but documented. Untreated dental infections can spread via blood or direct extension to: the jaw and neck (Ludwig’s angina), the chest (mediastinitis), the sinuses (sinusitis), and in very rare cases the brain (cerebral abscess) or heart valves (bacterial endocarditis). These complications are almost entirely preventable with prompt dental treatment. If you have facial swelling, fever or difficulty swallowing with a tooth infection, go to your nearest emergency department immediately.
Yes — Paynless Dental offers same-day emergency appointments for tooth infections at all three clinics. Call (02) 8677 9094 as early as possible. Open Mon–Fri 9:30am–6pm and Saturday at all locations (Toongabbie until 4pm, North Ryde and Blacktown until 3pm). If you have facial swelling, difficulty swallowing or fever — go to your nearest emergency department, not the dental clinic.
Emergency consultation and X-ray at Paynless Dental from $80–$250. Root canal treatment (the most common curative treatment) from $900 — cost varies by tooth type and canals. Extraction from $180 if the tooth is unrestorable. Antibiotics additional if prescribed. Written itemised quote with ADA item numbers before any treatment. Most health fund extras cover emergency consultations. CDBS bulk billing for eligible children 2–17. Call (02) 8677 9094.
A toothache is a symptom — pain or discomfort from a tooth, which can have many causes including decay, sensitivity or gum problems. A tooth infection (dental abscess) is a specific condition — a localised bacterial infection with pus formation. A toothache often precedes an abscess. The presence of swelling, pimple-like bump on the gum, bad taste/smell, fever or constant severe pain suggests infection rather than simple toothache. Both require dental assessment. See our toothache page for comparison.
No. A tooth infection that stops hurting has likely progressed to pulp necrosis (the nerve has died). The infection is still active at the root tip — continuing to destroy bone — but the pain signals have stopped. This is called a chronic periapical abscess and is particularly dangerous because patients assume the problem has resolved. Without treatment, the infection continues silently and can re-activate acutely at any time. Call Paynless Dental (02) 8677 9094 even if the pain has stopped.
Emergency drainage and antibiotics can begin at your same-day appointment — providing relief within 24–48 hours. Root canal treatment takes 1–3 appointments spread over 1–3 weeks. Extraction can be performed at a single appointment. After treatment, the body gradually reabsorbs the abscess cavity and bone regeneration begins. A follow-up X-ray at 6–12 months confirms resolution. Call Paynless Dental (02) 8677 9094.
Yes — a pimple-like bump on the gum (called a fistula or sinus tract) is a strong indicator of an active dental abscess. It is the abscess draining externally through the gum tissue — providing temporary pressure relief, which is why the tooth may not always be severely painful. The presence of a fistula means the infection is active and treatment is required. Do not assume the problem is resolving because it is draining. Call Paynless Dental (02) 8677 9094.
Yes — most private health fund extras policies cover emergency consultations, X-rays, root canal treatment and extractions under general or major dental. Cover depends on your policy and annual limit. Paynless Dental has HICAPS on-the-spot claiming for all major funds. CDBS bulk billing for eligible children aged 2–17. Call (02) 8677 9094 to confirm your cover before attending.
Yes — open Saturday at all three clinics. Toongabbie 9:30am–4pm. North Ryde and Blacktown 9:30am–3pm. Dental infections do not wait for weekdays. Call as early as possible on Saturday morning. Book online 24/7 or call (02) 8677 9094. Remember — if swelling is spreading or you have a fever with difficulty swallowing, go to ED.
Yes — most dental abscesses are entirely preventable. Brush twice daily with fluoride toothpaste. Clean between teeth daily with floss or interdental brushes. Attend professional dental check-ups every 6 months — early decay is treated before it reaches the nerve. Do not ignore toothache or sensitivity. Address broken teeth and failed restorations promptly. CDBS covers preventive care for eligible children 2–17. Call Paynless Dental (02) 8677 9094 to book your regular check-up. See our routine dental check-ups page.

No — antibiotics alone cannot cure a dental abscess. They reduce bacterial spread and symptoms temporarily but the source of infection (necrotic pulp or infected periodontal pocket) must be treated with root canal treatment, drainage or extraction to achieve a cure. A dental abscess treated with antibiotics alone will recur. Call Paynless Dental (02) 8677 9094. See Healthdirect — Tooth Abscess.
Go to your nearest emergency department immediately if you have facial swelling spreading to the jaw, neck or eye, difficulty swallowing or opening the mouth, difficulty breathing, or fever above 38°C with dental pain. These signs indicate a spreading infection — potentially life-threatening. Do not wait for a dental appointment.
Yes — untreated dental infections can spread to the jaw, neck (Ludwig’s angina), chest (mediastinitis) and in rare cases the brain or heart valves. These are serious and potentially life-threatening complications. All are preventable with prompt dental treatment. Call Paynless Dental (02) 8677 9094 at the first sign of infection.
Yes — same-day emergency appointments available at all three clinics. Call (02) 8677 9094 as early as possible. Open Saturday at all locations. If swelling is spreading, you have a fever or difficulty swallowing, go to your nearest emergency department rather than the dental clinic.
No. A tooth that stops hurting may indicate the nerve has died while the infection continues at the root tip as a chronic abscess. This is particularly dangerous because patients assume the problem has resolved. The infection continues to destroy bone silently. Call Paynless Dental (02) 8677 9094 even if the pain has stopped.
