Dental Cavitations: What Patients Should Know
A Term You May Have Heard
A dental cavitation is a term for an area of poorly healed or hollow bone in the jaw, often at a past extraction site. It is also called NICO or FDOJ. The diagnosis is debated: there is no agreed-upon standard for identifying cavitations, and a 2026 review suggested that many of these areas may reflect normal healing. Atlanta Dental Wellness does not treat cavitations, but we can help you understand the topic.
What the Terms Mean
| Term | Meaning |
|---|---|
| Cavitation | A general term for a hollow or poorly healed area in the jawbone |
| NICO | Neuralgia-inducing cavitational osteonecrosis, a term linking cavitations with facial pain |
| FDOJ | Fatty degenerative osteolysis of the jawbone, a term used mainly in Europe |
Why It Is Debated
Most research on cavitations comes from observational studies and case series. A systematic review found no gold-standard diagnostic method. A 2026 review noted that areas of incomplete bone fill at former extraction sites may be a normal result of socket healing rather than disease.
How They Are Evaluated
Standard X-rays often cannot show these areas clearly.
Cone beam CT imaging can show bone density differences, but interpreting them is debated.
Symptoms, such as facial pain, have many possible causes and need careful evaluation.
What We Can Do
We do not diagnose or treat cavitations. We can review your history and current imaging, check for other dental causes of pain or infection, and refer you to a qualified provider if you want further evaluation.
