Dental Abcess

A dental abscess is a pocket of pus that forms due to a bacterial infection in the tooth or surrounding gum tissues. It can be excruciatingly painful and, if left untreated, may lead to serious complications. Understanding the different types of dental abscesses, their causes, symptoms, and treatment is crucial for managing and preventing them.

Types of Dental Abscesses

  1. Periapical Abscess: This type affects the tip of the tooth root and usually occurs when bacteria invade the dental pulp through a cavity or crack.
  2. Periodontal Abscess: This affects the gums around the tooth and is often linked to advanced gum disease.
  3. Gingival Abscess: Involves the gum tissue and can arise from injuries to the gums by foreign objects like food particles.


  1. Tooth Decay: Untreated cavities can allow bacteria to reach the inner dental pulp, leading to an infection.
  2. Gum Disease: Advanced gum disease can cause pockets to form between the tooth and gum, which can harbor bacteria.
  3. Injury or Trauma: Cracks or fractures in the tooth or gum tissue can serve as entry points for bacteria.
  4. Weakened Immune System: Conditions like diabetes or treatments like chemotherapy can reduce the body’s ability to fight infections.


  • Pain: Sharp, throbbing pain that can radiate to the jaw, ear, or neck.
  • Swelling: In the gums, face, or neck.
  • Fever: An elevated temperature can indicate a spreading infection.
  • Sensitivity: Pain when chewing or sensitivity to hot or cold food and drinks.
  • Swollen Lymph Nodes: Particularly around the jaw or neck.
  • Bad Breath: A foul odor can arise from the infection.
  • Pus Discharge: In some cases, pus may leak from the infected area.


A dentist will diagnose an abscess through clinical examination and imaging like X-rays. The X-rays help locate the infection and assess its severity. This is not only a great way to treat the area, but to also create a plan to lower the chances of future dental abcesses.
