Cavitations in Dentistry: What They Are and How Holistic Dentists Treat Them

CAVITATIONS AND JAW HEALTH · LOS ANGELES

Jawbone lesions that conventional dentistry rarely diagnoses and almost never discusses.

Cavitations are areas of ischemic osteonecrosis in the jawbone, meaning tissue that has died due to inadequate blood supply. They often occur at old extraction sites, particularly wisdom tooth sockets, and can persist for years without showing up on standard dental X-rays. Patients with undiagnosed cavitations frequently report chronic facial pain, jaw aching, fatigue, and neurological symptoms that have no clear explanation. This guide explains what cavitations are, how they are identified, and what the current evidence does and does not support.

What Is a Cavitation and Why Does It Develop?

Cavitation, definition: in dentistry, a cavitation is a hollow or necrotic area inside the jawbone, most often at the site of a previous tooth extraction, where the bone failed to heal and regenerate normally. It is formally called NICO (Neuralgia-Inducing Cavitational Osteonecrosis) or FDOJ (Fatty Degenerative Osteonecrosis of the Jawbone), and you may also see it written as a jaw cavitation, a bone cavitation, or a dental cavitation. All of these describe the same finding.

Unlike a cavity in a tooth, which is bacterial decay on enamel, a cavitation is a problem inside the bone itself. That distinction matters, because the two are diagnosed and treated in completely different ways, and the word similarity causes a lot of confusion.

Cavitations most commonly develop when a tooth is extracted and the socket fails to heal completely. This happens when the periodontal ligament is not fully removed during extraction, the blood supply to the area is inadequate, or the patient has clotting disorders, certain medications, or nutritional deficiencies that impair bone regeneration.

The result is dead or dying bone tissue that does not remodel normally. The area can become an inflammatory focus in the body, producing cytokines and toxins that research has linked to chronic pain, immune dysregulation, and systemic symptoms in some patients.

Conventional dentistry does not routinely screen for cavitations. Standard 2D dental X-rays often miss them entirely. This means patients can carry these jawbone lesions for decades without a diagnosis.

Tooth and Jaw Cavitation Symptoms

Cavitation symptoms are frustratingly non-specific, which is exactly why the condition goes unrecognized for so long. Many cavitations produce no symptoms at all and are found incidentally during 3D imaging taken for another reason.

When symptoms are present, patients most often describe:

A persistent dull ache in the jaw with no visible dental cause. Facial pain or pressure that is difficult to localize, or that seems to move. Old extraction sites that remain tender years after the procedure. Recurring headaches with no clear trigger. An unpleasant taste or odor that does not resolve with cleaning. Trigeminal nerve pain in the affected region.

Some patients also report systemic symptoms including unexplained fatigue, brain fog, and patterns that resemble fibromyalgia or chronic Lyme disease. We want to be careful here: none of these symptoms are specific to cavitations, and many have other, more common explanations that should be ruled out first. The presence of these symptoms is a reason to investigate, not a diagnosis in itself.

This is also the honest limitation of the topic. Cavitations are recognized and treated within biological dentistry and documented in peer-reviewed literature, but the evidence base is still developing and the condition remains debated in conventional dental practice.

What a Cavitation Looks Like on an X-Ray

This is the single most common question about cavitations, and the answer explains why so many people go undiagnosed for years.

On a standard 2D dental X-ray or panoramic film, a cavitation frequently looks like nothing at all. A flat radiograph compresses the entire depth of the jaw into one plane. A hollow, poorly mineralized space that sits behind or beneath intact surface bone can be completely obscured by the healthy bone in front of it. Patients are told the film is clean, and the search for an explanation moves elsewhere.

On a cone beam CT scan, the same site can look entirely different. CBCT reconstructs the jaw in three dimensions, so the site can be examined slice by slice and from any angle. What clinicians look for is a region of reduced bone density, a poorly defined or absent socket outline at an old extraction site, and a trabecular pattern that does not match the surrounding healthy bone.

Imaging alone does not make the diagnosis. Findings have to be interpreted alongside history and symptoms.

How Cavitations Are Diagnosed and Treated

Diagnosis with cone beam CT (CBCT). 3D cone beam computed tomography gives a volumetric picture of the jawbone that standard panoramic X-rays cannot match. Changes in bone density, hollow areas, and signs of poor healing that are invisible on a flat X-ray become visible in 3D. CBCT is the primary diagnostic tool used to identify suspected cavitation sites.

Clinical correlation. Imaging findings are interpreted alongside the patient’s history. When did they have extractions? What symptoms have they experienced since? Do they have chronic facial or jaw pain that has never been explained? The combination of CBCT findings and patient history guides the diagnostic picture.

Surgical debridement. When a cavitation is confirmed, treatment involves surgically opening the site, removing the necrotic tissue, and creating conditions for the bone to heal properly. This is performed under local anesthesia, frequently with ozone therapy applied to the site, and alongside nutritional support to optimize healing. This is specialized oral surgery, and not every practice performs it.

Post-operative support. Treatment does not end at surgery. Nutrition, supplementation, and lifestyle practices that support bone regeneration matter throughout recovery, and follow-up imaging is used to confirm healing progression.

Where cavitations form
Wisdom tooth sites are the most common location, simply because those extractions are the most frequent and the sockets are the deepest. A cavitation can form at any site where a tooth was removed, and more than one site can be involved at the same time.

Who is most at risk
People with prior wisdom tooth extractions, patients who have taken bisphosphonate medications, people with a history of radiation to the jaw, and those with nutritional deficiencies in vitamin D, vitamin K2, and magnesium are at higher risk of impaired bone healing and cavitation formation.

Frequently Asked Questions: Cavitations in Dentistry

How do I know if I have a cavitation?

You cannot know from symptoms alone. Cavitations do not always cause pain and the symptoms they do cause (jaw aching, fatigue, facial pain, brain fog) are shared by many other conditions. Diagnosis requires CBCT imaging and clinical evaluation. If you have a history of extractions and have experienced unexplained chronic symptoms since those procedures, a jaw health evaluation with 3D imaging is the appropriate starting point.

What is the difference between a cavity and a cavitation?

A cavity is bacterial decay in the hard structure of a tooth, and it is treated with a filling. A cavitation is a hollow, poorly healed area inside the jawbone itself, usually where a tooth was removed, and it is treated surgically. The names are similar but the two conditions are unrelated.

Are cavitations recognized by mainstream dentistry?

Cavitations are recognized by the IAOMT (International Academy of Oral Medicine and Toxicology) and documented in peer-reviewed literature, though they remain controversial in mainstream dental practice. Many conventional dentists are unfamiliar with the concept or dismiss it. Biological and holistic dentists trained in IAOMT protocols are far more likely to screen for and identify cavitation lesions.

Can a cavitation heal on its own?

Once a site has failed to heal and necrotic tissue is established, it does not typically resolve without intervention. The underlying problem is inadequate blood supply to the area, and that does not correct itself. This is why treatment focuses on clearing the compromised tissue and restoring the conditions bone needs to regenerate.

Can ozone therapy help with cavitation healing?

Ozone has antimicrobial and tissue-stimulating properties, and it is commonly applied at the surgical site during cavitation debridement to reduce residual bacteria and support healing. Ozone is used across a wide range of procedures in biological dentistry. You can read more about how we use it on our ozone therapy page.

Where can I get evaluated for a cavitation?

Cavitation evaluation begins with 3D cone beam imaging and a thorough history. Because treatment is specialized oral surgery, patients are sometimes referred to a practitioner who focuses on it. Call our office at (818) 766-7776 and we can talk through your history, what imaging would show, and the right next step for your situation.
