A tooth infection occurs when bacteria reach the inner pulp of the tooth. Because infections rarely heal on their own, recognizing early signs is important.
‍

Common Warning Signs

• Persistent throbbing tooth pain
• Sensitivity to heat
• Pain when biting
• Swollen gums or face
• Bad taste or odor
• Darkening tooth color
  ‍

Why Infections Become Serious

The pulp contains nerves and blood vessels. Once infected, pressure builds inside the tooth, causing increasing pain and potential spread of bacteria.
‍

Temporary Care

• Keep area clean
• Avoid chewing on affected side
• Use cold compress for swelling
  ‍

Emergency Symptoms

Seek urgent care if you notice:

• Facial swelling
• Fever
• Difficulty breathing or swallowing
  ‍

Next Step

Treatment typically involves root canal therapy or extraction to remove infection and relieve pressure.
