Dental emergencies have a way of happening at the worst possible time—a cracked tooth at dinner, sudden pain in the middle of the night, or swelling that appears out of nowhere. But how do you know when something is a true emergency?
At Pitt Street Dental Centre in Sydney CBD, we prioritise emergency cases, ensuring that patients in urgent need can be seen as soon as possible. Here are the key signs that you shouldn’t ignore and that require immediate dental attention.
1. Severe and Persistent Pain
A mild toothache might not be urgent, but if the pain is intense, sharp, or throbbing, and it doesn’t go away, this could mean:
- A deep infection in the tooth’s nerve
- A cracked or fractured tooth exposing the nerve
- An abscess, which could lead to swelling and serious complications
Severe pain is a clear signal that something is wrong. Don’t wait—seek immediate care.
2. Swelling in the Face or Jaw
Swelling may not always be painful, but it can be a sign of a serious infection. If left untreated, an infection can spread to:
- The neck, potentially restricting your airway
- The sinuses, leading to further complications
- The brain (in rare, severe cases)
If you notice swelling in your face or jaw, especially if it’s spreading, contact a dentist immediately.
3. Uncontrolled Bleeding
If your gums or mouth won’t stop bleeding, this could indicate:
- A serious gum infection
- Trauma to soft tissues
- An underlying health condition
Spontaneous or excessive bleeding that doesn’t stop requires emergency dental attention.

4. A Lump, Bump, or Ulcer That Won’t Heal
Sores or ulcers that last more than two weeks and don’t seem to heal should be checked. Warning signs include:
- Irregular edges
- No pain (painless lesions can be more concerning)
- Growing in size
Persistent lumps or ulcers may need a biopsy to rule out serious conditions like oral cancer.
5. Dental Trauma from Injury or Accidents
Whether it’s from a sports injury, a fall, or biting into something hard, any damage to your teeth needs attention. Even if your tooth looks fine, it might:
- Be cracked below the surface
- Have nerve damage
- Be slightly out of alignment
The sooner you see a dentist after an injury, the better the chances of saving your tooth.
If you’re experiencing any of these signs, don’t ignore them. Dental issues can escalate quickly, leading to more pain, more damage, and more complicated treatments if left untreated.
