An abscess on the tooth is usually pus caused by bacteria. It can occur anywhere on the tooth, for various reasons. The three main kinds of abscesses are:

  2. Periodontal abscess – on the gum next to the root of the tooth
  3. Gingival abscess – on the gums


  1. Pain in ear, jaw, neck
  2. Worsening pain when you lie down
  3. Pain during eating

  5. Swollen gums
  6. Sensitive tooth
  7. Loose tooth
  8. Discolored tooth
  9. Halitosis, foul taste in the mouth
  10. Tender lymph nodes under your jaw

Relieving pain if the dentist is unavailable

  1. Teeth can get very sensitive in this time so avoid hot or cold drinks
  2. Abscesses are sensitive to pH changes, so avoid acidic drinks
  3. OTC painkillers, like panadol, can help reduce the pain
  4. Floss between the teeth that hurt the most, so any food particles or plaque can be removed, so that there is fewer chances of a further infection
  5. Get a temporary filling from the pharmacy
  6. Sleep with an elevated head
  7. Rise regularly, with warm saline water


To diagnose the teeth, doctors usually tap the teeth, see if it is hollow. If they are unsure, they get CT scans and X-rays to examine the situation.
