Infection of the Fenestration Cavity: Causes and Symptoms

A fenestration cavity is a pocket that forms between two teeth in the same jawbone. When bacteria invade these cavities, they can cause an infection, resulting in a range of symptoms and potential complications. In this article, we discuss the causes and symptoms of a fenestration cavity infection.


The primary cause of a fenestration cavity infection is bacteria. Bacteria can enter the pocket through a variety of avenues, such as from food particles and plaque that become trapped in the cavity, or from saliva or other fluids. Additionally, the pocket is likely to form because of earlier dental treatments, so treatments such as root canals or extractions may be the source of the infection.


Symptoms of a fenestration cavity infection depend on the extent of the infection and may include:

  • Swelling of the gum in the area of the cavity
  • Pain or sensitivity in the area of the cavity
  • Foul-smelling breath
  • Bleeding in the area
  • Drainage of pus from the cavity


If left untreated, a fenestration cavity infection can lead to other dental issues, such as gum disease or permanent damage to the bone and tissue surrounding the area. It is important to realize that a fenestration cavity infection can spread to other parts of your mouth, which is why it is important to have the infection treated to prevent further complications.


Treatment for a fenestration cavity infection typically involves antibiotics to help reduce the infection and clear the cavity. In some cases, a dentist may need to perform a minor surgical procedure to remove the infection. Additional treatments may include special medications to help reduce the inflammation or scaling to remove plaque buildup.


The best way to prevent a fenestration cavity infection is to practice good oral hygiene. Brushing your teeth twice a day, flossing daily, and using mouthwash as recommended will help reduce the risk of infection. Additionally, it is important to get regular dental check-ups and notify your doctor of any concerning symptoms.
