Understanding Dental Abscesses

A dental abscess is a pocket of pus that forms in different parts of a tooth as a result of a bacterial infection. It can be very painful and can lead to more severe health complications if not treated promptly and appropriately.

Types of Dental Abscesses:

  1. Periapical Abscess: Forms at the tip of the tooth's root.
  2. Periodontal Abscess: Forms in the gums next to a tooth root.
  3. Extending to the surrounding structures: extends beyond the tooth towards the jaw bones, eyes, neck

Symptoms of a Dental Abscess:

  • Throbbing pain in the affected tooth or gum that may radiate to the ear, jawbone, or neck.
  • Sensitivity to hot or cold temperatures.
  • Swelling in the face or cheek.
  • Tender, swollen lymph nodes under your jaw or in your neck.
  • Fever.
  • A sudden rush of foul-tasting and smelling fluid in your mouth if the abscess bursts.

Complications with Extension to Adjacent Soft Tissue:

If not treated promptly, the infection from a dental abscess can spread to nearby tissues, leading to potentially serious complications.

  1. Eye: If the abscess is near an upper tooth, the infection might spread to the surrounding eye region, leading to swelling, pain, and potential vision problems.
  2. Neck: An infection can cause swelling in the neck, leading to pain and difficulty breathing or swallowing.


  1. Draining the Abscess: Your surgeon might make a small incision in the abscess to allow the pus to drain out. If severe, general anesthesia might be required with opening the abscess via the skin 
  2. Root Canal Treatment: This can help eliminate the infection and save your tooth.
  3. Tooth Extraction: If the tooth can't be saved, it might need to be extracted to prevent the spread of infection.
  4. Antibiotics: If the infection has spread to adjacent tissues or if you have a weakened immune system, you might be prescribed antibiotics


  • Maintain a thorough oral hygiene routine, including regular brushing, flossing, and dental check-ups.
  • Avoid sugary foods and drinks which can encourage bacterial growth.
  • Address dental issues promptly to prevent complications.

When to Seek Immediate Medical Attention

If you experience any of the following, it might indicate that the infection is spreading:

  • High fever.
  • Swelling in the face or cheek.
  • Difficulty breathing or swallowing.
  • Unbearable pain not under control with over-the-counter painkillers 

In such cases, it's crucial to seek immediate dental or medical attention or visit an emergency room.

Remember, a dental abscess won't go away on its own and can lead to life-threatening complications if not treated. If you suspect you have an abscess or are experiencing severe dental pain, consult your dentist or healthcare professional as soon as possible.
