Facial Swelling

An infected tooth with an abscess (accumulation of pus) is a common cause of facial swelling (cellulitis). A deep cavity allows bacteria to enter the nerve of the tooth and travel through the tooth into the surrounding bone and tissues. If the infection remains localised an abscess will form next to the tooth. However where an infection spreads it can cause a facial swelling/cellulitis and appear on the skin as an area of redness and swelling which is hot to touch and often painful. Depending on which tooth is infected, the associated swelling can cause difficulty with swallowing, mouth opening or even swelling of the eyelids.

 

Often dental treatment is delayed until the facial swelling has resolved as local anaesthetics tend to be less effective. A course of oral antibiotics can be prescribed however for more severe cases IV antibiotics may need to be administered.

Facial swelling is a very serious condition. A bacterial infection can spread rapidly, entering the lymph nodes, bloodstream and spread throughout the body.

 

See your dentist immediately or head to the emergency department of your local hospital if you notice:

  • facial swelling around the eye
  • facial swelling around the throat area especially is there is difficulty swallowing or breathing
  • swelling that is associated with a fever, chills or vomiting
