A root canal becomes an emergency when severe pain or infection threatens your oral health. Knowing the warning signs can help you seek timely treatment and prevent tooth loss.

Signs You May Need an Emergency Root Canal

1. Intense, Persistent Tooth Pain

If you’re experiencing severe, throbbing pain that doesn't go away with painkillers, it may indicate an infected or dying tooth nerve.

2. Swelling in the Gums or Face

Swollen gums, a tender jaw, or facial swelling suggest a spreading infection that needs immediate attention.

3. Sensitivity to Hot or Cold

Prolonged sensitivity to hot or cold foods—even after the stimulus is removed—is a sign of nerve damage.

4. Darkening or Discoloration of a Tooth

A greyish or blackish tint on your tooth can indicate severe decay or a dead tooth nerve, requiring urgent treatment.

5. Pimple-Like Bump on the Gums

A recurring bump on the gum near the affected tooth (dental abscess) is a clear sign of infection and must be addressed immediately.

What Happens During an Emergency Root Canal?

During an emergency root canal, your dentist will:
✅ Remove the infected pulp
✅ Disinfect the tooth’s interior
✅ Fill the space with a biocompatible material
✅ Seal the tooth to prevent reinfection

In severe cases, additional treatments like an incision to drain an abscess or antibiotics may be required.

Preventing Dental Emergencies

???? Maintain good oral hygiene by brushing twice daily and flossing regularly.
???? Visit your dentist every six months for checkups.
???? Avoid chewing hard foods or using your teeth as tools.

If you experience severe pain, swelling, or other signs of infection, seek emergency dental care immediately. Delaying treatment can result in tooth loss or systemic infections. Early intervention ensures better outcomes and preserves your natural tooth.
