When is toothache an emergency?
Severe toothache rarely resolves on its own. Most true dental emergencies are driven by two underlying conditions — acute irreversible pulpitis (inflammation of the nerve inside the tooth) and acute apical abscess (infection that has tracked through the root and into the surrounding bone). Both are best managed with definitive endodontic treatment, not with analgesics or antibiotics alone.
You should seek urgent endodontic assessment if you have any of the following:
- Severe, unrelenting toothache that does not respond adequately to over-the-counter pain relief.
- Spontaneous, throbbing pain — particularly pain that wakes you from sleep.
- Prolonged sensitivity to hot or pain that lingers for minutes after a stimulus is removed.
- Facial or gum swelling originating from a tooth.
- A raised, tender bump on the gum (sinus tract / parulis) with or without pus discharge.
- A knocked-out or displaced permanent tooth after trauma.
- Severe pain or swelling following recent dental treatment.
- A tooth that feels raised or painful to touch and biting.
What to do right now
While you are organising an appointment, there are some sensible steps that can reduce pain and protect the tooth:
- Take over-the-counter pain relief in appropriate doses. Alternating ibuprofen and paracetamol is generally more effective than either alone (if there are no contraindications). Follow the package instructions and do not exceed the stated daily dose.
- Avoid heat — heat packs, hot drinks and hot food make pulpitis worse. Use cold compresses on the outside of the face if there is swelling.
- Chew on the other side and avoid hard or crunchy food on the affected tooth.
- Keep the area clean with gentle brushing and a warm saltwater rinse (half a teaspoon of salt in a glass of warm water) two or three times a day.
- Stay upright where possible — lying flat often increases pulpal pain by raising pressure inside the tooth.
For a knocked-out (avulsed) adult tooth, time is critical. If possible, pick the tooth up by the crown (not the root), rinse it briefly under cold running water if dirty, and place it back into the socket. If reimplantation is not possible, transport the tooth in milk or saliva (never water) and come in without delay. See our dental trauma management page for more detail.
What happens at an emergency appointment
The priority at the first appointment is to get you out of pain safely and to stabilise the tooth. A typical emergency consultation includes:
- History and examination — a focused history of symptoms, onset, and triggers, followed by clinical tests (percussion, palpation, pulp testing, bite tests).
- Imaging — a periapical radiograph, and CBCT imaging if complex anatomy or atypical features are identified.
- Diagnosis — we clearly explain what is causing the pain and what the treatment options are.
- Effective local anaesthesia — for teeth that are difficult to numb (the classic "hot" lower molar), supplementary techniques such as intraligamentary and intraosseous anaesthesia are used so the tooth is properly numb before treatment.
- Pulpotomy or pulpectomy — the inflamed or necrotic pulp tissue is removed under rubber dam, the canal system is disinfected, and in many cases the canals are shaped and medicated.
- Drainage of any abscess — through the tooth where possible, which is almost always the most effective way to relieve acute apical pain.
- Interappointment dressing — calcium hydroxide or an equivalent medicament is placed, and the access cavity is sealed with a temporary restoration.
Most patients leave the emergency appointment with dramatically reduced pain — often immediate relief. Definitive completion of the root canal treatment is then arranged at a follow-up appointment.
Will a single visit resolve it?
Sometimes — but not always, and that is not the priority in an emergency. In straightforward cases, the root canal treatment can be completed at the same appointment. In more complex cases (large periapical swellings, necrotic teeth with heavy bacterial load, patients with severe acute pain, difficult anatomy) a two-visit approach with calcium hydroxide dressing between appointments gives a more predictable result.
What matters most in an emergency is that the source of the pain is removed safely. Rushing a complex root canal treatment in a highly symptomatic tooth is not in the patient's interest. Our priority is pain relief first, predictable long-term outcome second.
Do I need antibiotics?
In most cases, no. The source of most dental pain and localised abscesses is bacteria inside the root canal system — and these bacteria are protected from antibiotics by the absence of a blood supply. Definitive treatment is drainage and removal of the source, which requires endodontic treatment or extraction, not antibiotics.
Antibiotics are genuinely indicated in specific circumstances:
- Spreading facial or neck infection (cellulitis).
- Systemic involvement — fever, malaise, tender lymph nodes.
- Patients who are medically compromised or immunosuppressed.
- Following appropriate drainage, where spread has already occurred.
Unnecessary antibiotic prescription delays definitive care, drives antimicrobial resistance, and exposes patients to side effects without addressing the underlying problem. We follow Australian Therapeutic Guidelines for antibiotic use and prescribe only where clinically indicated.
What about out-of-hours emergencies?
For emergencies occurring outside our practice hours:
- Attend the nearest hospital emergency department if there is significant facial swelling, difficulty breathing or swallowing, fever, or dental trauma involving multiple teeth. Liverpool Hospital (Elizabeth Street, Liverpool) is the closest ED to our practice.
- For severe toothache without those features, take appropriate analgesia, apply cold compresses, and call us first thing the next business day on (02) 9129 8806.
- For avulsed teeth, reimplant immediately if possible and present to a dentist or ED without delay — the first hour is the most important window.
Wollongong patients: Emergency endodontic appointments are also available at our sister practice, Wollongong Endodontics — the only specialist endodontic clinic in the Illawarra.
For referring dentists
We welcome urgent referrals from general practitioners. If you have a patient with uncontrolled pain, a hot lower molar that won't numb, a swelling that requires CBCT assessment, or trauma outside the scope of general practice — call (02) 9129 8806 for a pre-referral discussion. Where clinically appropriate, we will triage the case and offer a same-day appointment so your patient is not left in pain.
Written and radiographic referrals can be submitted via our online referral form. For urgent cases, phoning the practice ensures the fastest response.

Frequently Asked Questions
True endodontic emergencies include severe, unrelenting toothache that doesn't respond to over-the-counter pain relief; facial swelling originating from a tooth; a knocked-out (avulsed) permanent tooth; a tooth that has been displaced after trauma; and acute pain or swelling following recent dental treatment. Persistent throbbing pain, pain that wakes you from sleep, and visible swelling are all signs of acute pulpitis or acute apical abscess and should be assessed urgently.
Yes, where clinically indicated. We reserve time in our daily schedule specifically for emergency patients. Call our Liverpool practice on (02) 9129 8806 as early in the day as possible. We will triage your symptoms by phone and fit you in the same day where appropriate.
Take regular over-the-counter pain relief (ibuprofen and/or paracetamol) in the correct combined doses if you have no contraindications. Avoid heat application to the area, avoid hard chewing on the affected side, and keep the tooth as clean as possible. For an avulsed (knocked-out) adult tooth, place it back in the socket immediately if possible, or transport it in milk or saliva — and come in without delay. Bring a list of current medications and allergies.
Antibiotics are not a substitute for definitive endodontic treatment. Most toothache and localised dental abscesses are resolved by drainage and removal of the source of infection, not by antibiotics. Antibiotics are reserved for specific situations: spreading facial infection, systemic involvement (fever, lymphadenopathy), or immunocompromised patients. Over-prescription of antibiotics contributes to resistance and does not treat the underlying problem.
Not always. The first emergency appointment focuses on getting you out of pain — usually by opening the tooth, removing the inflamed or infected pulp tissue, draining any pus, and placing an interappointment medicament. Definitive completion of the root canal may occur at the same visit or at a follow-up appointment, depending on symptoms, anatomy and complexity. What matters most in an emergency is relieving pain safely and protecting the tooth from further damage.
For emergencies occurring after hours or on weekends, please attend the nearest hospital emergency department if there is significant facial swelling, difficulty breathing or swallowing, fever, or trauma involving multiple teeth. For severe toothache without those features, take appropriate analgesia and call us first thing the next business day on (02) 9129 8806 for an urgent appointment.
