Dental AI X-Ray Analysis: A Guide for Practices

A patient sits in the chair while you review a set of bitewings. Software has already drawn boxes around three spots: a possible cavity, an area of bone loss and a shadow at a root tip. You agree with two of them.

That is dental AI x-ray analysis in practice. It does not read radiographs instead of you. It reads them alongside you, and it is now used widely enough that small dental practices are being asked whether they want it. This guide explains what it does, what FDA clearance actually means, and what to ask before you sign.

What dental AI x-ray analysis does

The software takes each dental x-ray your sensors already capture and runs it through an algorithm. These are deep learning models, a form of machine learning, trained on large sets of labeled dental radiographs. The image analysis then marks findings for the dentist to review.

Common detection targets include:

• Caries, including early lesions on bitewing and periapical images
• Bone loss, with measured bone levels that support periodontal charting
• Periapical radiolucencies that may point to infection at the root
• Existing restorations, calculus and other findings, depending on the product

Some products also enhance the image itself, adjusting contrast so subtle findings are easier to see. Different products cover different image types. Some handle bitewing and periapical images only. Others add panoramic images and CBCT scans. Check which of your image types each product actually covers.

What FDA clearance means here

Artificial intelligence that helps diagnose disease from a medical image is a medical device, so these products need FDA clearance before they are marketed in the US. Two early clearances show what that clearance covers.

Overjet's Dental Assist received what the company described as the dental industry's first FDA clearance for AI on May 20, 2021, for measuring bone levels. Pearl's Second Opinion was cleared on March 4, 2022 (K210365). It helps detect caries on periapical radiographs of permanent teeth, in patients 12 and older, as a second reader.

Two details in that clearance matter for every product you look at.

• "Second reader." The software is an aid to the dentist, not a replacement. The diagnosis and treatment planning stay with you.
• The indication is specific. A clearance covers particular image types, findings and patient ages. Using it outside that indication, such as on children's teeth before a pediatric clearance exists, is outside what was cleared.

Vendors have added clearances since, covering more findings and image types. Ask for the clearance numbers and read the indications yourself in the FDA's public 510(k) database.

Does AI replace the dentist's judgment?

No, and the clearances say so. These tools are cleared for use by dental professionals, as part of dentistry as you already practice it. The software flags and measures. A dentist decides what is real, what needs treatment and what to watch.

Image quality matters as much as the software. The analysis works best on high-quality images; a cone cut, an overlapped contact or an underexposed sensor image produces weaker results, just as it does for a human reader.

Expect disagreements. The software will mark things you do not agree with and miss things you see. That is how a second reader is supposed to work. Treat the overlays as a prompt to look again, not as a verdict.

How it fits your workflow

Dental AI tools typically connect to the imaging software or practice management system you already use. Images are sent to the vendor's service, analyzed, and returned as overlays in your normal viewer while the patient is still in the chair.

Before you buy, confirm three things:

1. Your imaging software is supported, by name and version.
2. Where the images go. Cloud analysis means radiographs leave your office, so the vendor needs a business associate agreement.
3. What happens when it is offline. Your diagnostic workflow should never depend on an internet connection.

Many dentists also use the overlays chairside. Showing a patient the marked image makes a finding easier to explain, which supports patient care and informed consent. Keep that honest: the overlay is a teaching aid, not proof.

The privacy and security side

Radiographs are protected health information. Sending them to an AI service puts that vendor inside your HIPAA obligations.

• A signed business associate agreement before any real image is uploaded
• A clear answer on whether your images are used to train the vendor's models
• Encryption of images in transit and at rest
• Access to the overlays limited to staff who need them

The imaging PCs themselves deserve attention too. They often run older software that sensor vendors are slow to update. Our guide to dental practice cybersecurity covers how to protect them. For judging an AI vendor's answers, see whether AI is HIPAA compliant.

What it costs

Dental imaging AI is sold by subscription, usually per location, and the main vendors quote prices individually rather than publishing them. Costs vary with the number of operatories, the features you want and whether you have more than one office.

To compare fairly, ask each vendor for:

• The monthly price per location, and what is included
• Any setup or integration fee
• Contract length and the cost of leaving early
• Whether chairside patient views cost extra

Get at least two quotes. Then decide what you are paying for: a second reader on every image, consistent periodontal charting, or a clearer conversation with patients. Each is a different reason to buy.

Questions to ask every vendor

1. Which FDA clearances cover the findings and image types we would use?
2. Which of our image types and patient ages are inside those indications?
3. Does it integrate with our imaging software and practice management system?
4. Will you sign a BAA, and do you train your models on our images?
5. What does it cost per location, and what are the exit terms?

Treat it like any other vendor that handles patient data. Our guide to vendor risk management covers the review, and an AI policy for your practice sets the rules for how the team uses it.

The bottom line

Dental AI x-ray analysis is mature, FDA-cleared for specific uses, and practical for a small practice to adopt. It works best as what it was cleared to be: a second reader that makes you look again.
