Oral and Facial Swelling

What May Cause Oral or Facial Swelling?



  • Severe inflammatory response to virus or bacteria

  • Infection- most commonly caused by teeth

  • Allergy or hypersensitivity

  • Abnormal mass related to pathology

  • Bleeding in the form of a hematoma- this may occur following surgery or trauma.

  • Contusion or a simple bruise from trauma

  • Jaw fractures or other injuries related to trauma


How do I know if swelling is from infection?



  • Pain may be in one area or radiating in different directions

  • Warmth over the skin

  • Redness over the skin

  • Drainage of pus inside the mouth or on the face

  • Pain from a tooth or other sources preceding the swelling

  • Possible difficulty opening mouth

  • ‘Gum boil’- a small pimple-looking swelling over gum tissue


Managing Pain and Swelling from Infection:


If you are experiencing facial or gum tissue swelling with possible drainage of pus or difficulty opening mouth:

  • Take 400-600 mg ibuprofen (2-3 tablets of Advil) or 500-1000 mg of Tylenol every four to six hours.

  • Call your dentist immediately for evaluation or referral to an oral surgeon.

  • Begin antibiotic therapy immediately. If you cannot see an oral surgeon right away, ask your dentist to prescribe antibiotics and pain medication.

  • Extractions should be done as soon as possible, before the infection spreads and involves other areas of face with potentially life-threatening consequences. It is not necessary to be on antibiotics for a few days before surgery, as the condition can worsen quickly. This approach is outdated and no longer recommended.

  • Do not apply ice. It does not improve swelling caused by infection.

  • Do not place a heat pack on the face as it can draw the pus from the infection towards the skin and cause scarring.
