Endodontics is the branch of dentistry that focuses on diagnosing and treating problems inside the tooth — specifically the dental pulp (nerve) and surrounding tissues. These emergencies often occur due to infection, trauma, or deep decay.
At Brisbane Emergency Dentist, we understand that dental pain can be unbearable. Our emergency team is available to provide immediate relief and save your natural tooth whenever possible.
Endodontic emergencies are generally classified into three main categories, depending on when they occur:
These involve acute pain or swelling before any root canal therapy has started. Common causes include severe tooth decay, pulp infection, or trauma exposing the inner tooth pulp.
These occur during a dental procedure — for example, accidental pulp exposure, flare-ups during root canal treatment, or an infection developing mid-treatment.
Sometimes, pain or swelling may occur after a root canal has been completed. This can happen due to overfilling, incomplete cleaning, or reinfection caused by cracks or new decay.
Recognising the signs early can help you seek timely treatment and prevent severe complications. Common symptoms include:
- Sharp, throbbing, or radiating tooth pain.
- Pain that worsens at night or when lying down.
- Sensitivity to heat or cold that lingers after exposure.
- Swelling in the gums, jaw, or face.
- A pimple-like bump (abscess) on the gums.
- Pain when biting or chewing.
- Fractured or cracked tooth.
- Fever or general feeling of illness.
In severe cases, the infection may spread to the jaw or facial tissues, leading to life-threatening swelling if not treated promptly.
You should seek emergency dental care immediately if:
- You experience sudden, intense tooth pain.
- There’s noticeable swelling around the gums or face.
- You suspect a tooth abscess or pus discharge.
- A tooth has fractured and exposed the inner nerve.
Delaying treatment can result in the infection spreading or even tooth loss. Our emergency dentists in Brisbane can provide same-day diagnosis and pain relief, ensuring the infection is controlled quickly.
Endodontic emergencies can often be prevented through good oral hygiene and regular dental visits. Follow these simple steps:
- Brush and floss daily to remove plaque and bacteria.
- Visit your dentist every 6 months for check-ups and cleanings.
- Avoid biting hard foods like ice or nuts.
- Treat cavities early before they reach the tooth pulp.
- Wear a mouthguard if you grind your teeth or play contact sports.
By maintaining routine care, you can catch small problems before they become painful emergencies.
At your emergency visit, our dentist will:
- Conduct a thorough examination and X-rays to locate the source of pain.
- Administer local anaesthesia to provide immediate relief.
- Drain any abscess or infection if present.
- Begin root canal treatment to remove the infected pulp and clean the tooth.
A temporary filling will be placed to seal the tooth, followed by a permanent crown or restoration in a follow-up visit to strengthen and protect it.
After your emergency root canal, it’s normal to experience mild sensitivity for a few days. Our dentist may prescribe antibiotics or pain relievers if necessary.
To restore strength and function, a permanent dental crown may be recommended once healing is complete. This protects the treated tooth from fractures and ensures long-term durability.
If you experience swelling, persistent discomfort, or pressure after treatment, contact our clinic immediately for follow-up care.
Tooth pain and infection won’t heal on their own. The sooner you receive endodontic treatment, the better your chances of saving your natural tooth.
