How Does A Cavitation Form In Bone?
Cavitations form when the bone fails to heal correctly after an injury or a dental procedure. The process begins with necrotic bone or tissue becoming trapped in the area, leading to poor blood supply, inflammation, and the accumulation of abnormal tissue. Over time, this creates a pocket of irregular tissue in the jawbone, disturbing its normal structure and function.
How Does a Cavitation Form?
A cavitation forms when the normal healing process in the jawbone is disrupted, leaving behind a pocket of unhealthy or abnormal tissue instead of healthy, mineralized bone. This can happen due to a combination of factors, including trauma, infection, poor blood flow, or incomplete healing after dental procedures. Explanations of how a cavitation may form in the jawbone are
Tooth Extraction Can Result In A Cavitation
Cavitations often begin with an event that damages the jawbone, such as a tooth extraction, infection, or jaw trauma. For example, after a tooth is extracted, the socket where the tooth once sat is exposed to the oral environment. This exposure may heal poorly leading to bone resorption and pathological cells filling the hole instead of healthy bone.
Unhealthy Bone and Tissue Accumulate In The Jaw Bone
Normally, the body breaks down unhealthy bone and tissue during the healing process after a dental extraction. However, if the unhealthy pieces of bone and tissue remain trapped in the socket, they can interfere with the bone’s ability to heal properly. It is speculated that these trapped necrotic pieces can create a lesion that becomes filled with irregular tissue instead of bone.
Lack of Blood Supply Can Result In A Cavitation
Healthy bone requires good blood flow to deliver nutrients and oxygen for repair and regeneration. In cavitations, the blood supply to the affected area may be insufficient, preventing the formation of new, healthy bone. Instead, the area becomes filled with abnormal tissue, such as fat cells, inflammatory cells, or pathogens, which further impairs healing.
Chronic Inflammation or Infection Can Cause A Cavitation
If bacteria or other pathogens are present, they can cause chronic inflammation, which may contribute to the formation of a cavitation. Inflammation can prevent the body from properly repairing the damaged area.

What Is In A Cavitation?
Over time, the poorly healed area may become a pathological pocket of unhealthy tissue within the jawbone. This tissue might include:
Fat cells, which are not normally found in the jawbone.
Inflammatory cells, indicating an ongoing immune response.
Dead or infected tissue, which can harbor pathogens or toxins.
Changes in Bone Structure Can Cause A Cavitation
To compensate for the weakened area, the outer layers of the jawbone (the cortical bone) may thicken, while the spongy inner bone (cancellous bone) remains poorly mineralized and weak. This imbalance creates further structural instability in the jaw. The weakened area may need to be opened up, cleaned and grafted with bone-stimulating material to heal with normal, strong bone.
Delayed or Incomplete Healing Can Cause A Cavitation
The longer the abnormal tissue remains in the jaw, the harder it becomes for the body to replace it with healthy bone naturally. The lesion may persist as a cavitation, creating a chronic site of weak bone. Placing bone-stimulating grafting material in a tooth socket after a tooth extraction encourages healthy bone formation.
What Are The Risk Factors for Forming A Cavitation:
Incomplete removal of diseased tissue during tooth extractions.
Failure to fill the empty extraction site with bone-stimulating graft material.
Chronic infections, such as those from untreated or improperly treated root canals.
Reduced blood flow or underlying conditions that impair healing, such as diabetes or autoimmune diseases.
Trauma or clenching in areas of high stress, like the bone around molars and wisdom teeth.
