By DentGen Editorial Team

An abscess is a collection of infection associated with a tooth or surrounding tissues.

QUICK ANSWER

How do I know if I have a tooth abscess?

Dental abscess symptoms can include severe tooth pain, swelling, tenderness, bad taste or fever, but only an examination can confirm the cause.

Warning signs

  • Increasing facial swelling
  • Severe throbbing pain
  • Fever
  • Bad taste or drainage
  • Tender lymph nodes
  • Difficulty opening the mouth

Reduced pain does not always mean the infection has resolved.

Difficulty breathing or swallowing, rapidly spreading facial swelling or systemic illness can require emergency medical attention.

Questions to ask at your consultation

  • Is drainage required?
  • What symptoms require immediate escalation?
