3D CBCT Dental Scan: Beyond the Tooth

A patient arrives with a toothache. The immediate temptation is to identify the damage, relieve the pain, and repair or remove the failing tooth. Dr. Candida Castillo starts with another question: why does it hurt? The cause may be the tooth, but it could also involve inflammation or infection in the bone. A 3D CBCT dental scan can reveal what a traditional 2D X-ray cannot, including detailed views of bone, fractures, airway signs, and findings that require attention beyond the dental office.

The question that changed how Dr. Candida Castillo practices

Dr. Castillo's approach to biological dentistry began while she volunteered at a homeless shelter. The dentist beside her, then the only biological dentist in Rhode Island, encouraged her to consider the connection between the mouth and body. The lesson became concrete when patients returned with bleeding gums after treatment or developed cavities after months of dental work and conversations about brushing and diet.

The pattern exposed the limits of treating one tooth at a time. If the work was complete and the patient had received instructions, why did disease return? Dr. Castillo began asking whether pain came from the tooth, inflammation, or another issue in the body. She also paid closer attention to patients' sleep, energy, and ability to heal.

Her practice now uses PRF, ozone, laser technology, and the SMART protocol for safe mercury removal. PRF uses the patient's own blood to support healing. But procedures are only part of the work. Some patients have stayed with the practice for 15 years, while some hygienists have worked with Dr. Castillo for over 10 or 15 years. She says patients may forget which technology was used, but they remember being treated like family. That continuity helps the team recognize when healing does not proceed as expected.

What a 3D CBCT dental scan adds

A 2D X-ray is useful but limited. Dr. Castillo says 3D CBCT allows her team to analyze bone at the level of every millimeter. That view can matter when an infected tooth was extracted but bacteria or infection remained, encapsulated in the bone. The problem may not appear on a regular X-ray, not because the dentist overlooked it, but because the technology could not display it.

The scan may also reveal tooth fractures that are hard to detect on a 2D X-ray, as well as signs of a possible airway issue. A sign on dental imaging is not a medical diagnosis. It gives the dentist a reason to inform the patient and recommend further investigation, perhaps with a sleep doctor or physician.

A sign on dental imaging is not a medical diagnosis.

Dr. Castillo usually sends CBCT scans to a radiologist unless she is imaging a specific procedure for follow-up. Systematic review, respect for the limits of dental practice, and an appropriate referral process make the scan useful. Information that another healthcare provider needs should not remain buried in a dental chart.

When a dental image goes to the cardiologist

Dr. Castillo requests carotid evaluation in her radiology reports, some of which return with carotid plaque findings. She does not turn that observation into a medical diagnosis. Patients instead take the report to their cardiologists, who sometimes did not know about the finding. A scan ordered for a dental concern can raise a separate question requiring medical follow-up.

The same caution applies when patients report changes after treatment. John returned for a second extraction approximately two months after removal of his first infected tooth. His wife said he had been sleeping better and experiencing less anxiety since the earlier surgery. The observation matters, but it does not prove the extraction caused either change. Dr. Castillo was explicit: the tooth was removed because it was infected, and treating the site reduced a source of inflammation in his body.

Patients need not interpret their own scans, but they can ask practical questions. Does the dentist use 3D CBCT when clinically appropriate? Does a radiologist review the scans? If an airway sign, carotid finding, fracture, or bone infection appears, is there a process for explaining it and sharing the information with medical professionals? The value of the scan is knowing what it supports, what it cannot prove, and when another provider should take the next step.
