In a dental office, an algorithm's finding can enter a chart before anyone checks whether it is right.
That risk is already part of daily practice. Dental teams use AI for imaging, charting, treatment planning, insurance work and patient apps, yet adoption is moving faster than professional understanding.
Overjet reports 11 FDA 510(k) clearances across its dental-AI products. Its CBCT Assist received FDA clearance in December 2025 and can identify, label and segment anatomical and restorative structures while measuring bone levels, airway dimensions and tooth positions.
Three roles create three different risks
In practice, AI can act as a source, a counterparty or an agent. As a source, it produces findings such as crestal-bone measurements, marked defects, furcation findings and risk scores. Its confidence does not show where it may fail, especially among patients who are poorly represented in its training data.
As a counterparty, AI becomes an adviser a patient consults before the appointment. It may offer reassurance that the clinician then has to challenge. As an agent, it can draft notes, code claims and start actions, so an incorrect instruction can move through the practice with little friction.
Speed does not make a wrong action safer.
The wider digital shift is also visible in an earlier imaging report. But wider adoption does not show that a particular clinical output deserves trust.
Large language models have shown materially unstable performance on a prosthodontics board examination. In 2024, ChatGPT-4 accuracy fell from 64.0% to 51.3% when the examination was repeated two weeks later, a statistically significant decline of 12.7 percentage points.
Polished answers can weaken scrutiny
The main danger is automation bias. When clinicians see a machine's answer first, they agree with it more often, including when it is wrong. They also search less hard for evidence that could disprove it.
A system that is usually accurate can teach users to stop checking at the moment an independent review matters most. Better software can create a more convincing failure.
Dentistry already applies a basic rule to other powerful tools: equipment may be easy to operate, but that does not make its user competent to use it safely. Radiographic equipment still requires training. Owning an implant kit does not prove surgical competence. AI should meet the same standard.
Competence must come before deployment
Before using an AI system, clinicians need to know how it was trained, what it is built to do and how it tends to fail. They also need to know what information it records or shares, which outputs need an independent check and which decisions must stay with a clinician. The machine may produce the finding, but the clinician remains accountable.
FDA-cleared dental AI shows where that line sits. Overjet's system outlines findings such as caries, calculus, periapical radiolucencies, restorations and bone levels. The dentist still makes the clinical decision. Its stated age limits matter too: caries detection begins at age 4, while periapical-radiolucency detection begins at age 12.
In the United States, regulated clinical software is subject to medical-device controls. The FDA 510(k) framework evaluates substantial equivalence to a legally marketed predicate device. That product-specific route is not one comprehensive standard for deploying dental AI in practice.
If an algorithm misses a furcation, understates pathology or produces an inaccurate clinical note, "The system flagged it" will not be a defence. The patient and the regulator will ask what the clinician concluded.
Implementation is therefore a professional process, not a purchasing decision. Dental schools, regulators, professional associations, vendors and practice owners all have a role in setting the order of education, validation and safeguards before deployment.
AI can support dentistry, but it cannot take over dental judgment. Clinicians may delegate selected tasks, never accountability. No practice should deploy an AI platform until its team can explain the system's limits as clearly as its benefits.
