How we use your X-rays

A plain-English explanation of what happens when you contribute X-rays to help train our dental X-ray tool.

What happens to my X-rays?

When you contribute X-rays, we store them in a private storage area that only our systems can access. They are not shown to anyone else and are not published.

Before an X-ray is used to train our dental X-ray tool, we de-identify it. Until then, it is not used for training at all.

What does de-identified mean?

We remove the things that could tell someone the X-ray is yours:

  • Hidden file information (metadata), such as dates, device details and location.
  • Text printed onto the image, such as your name, date of birth, the date it was taken, or the clinic name. We black it out.
  • The file name. We rename every image with a random code.

If we can't remove the printed text from an image with confidence, we don't use that image for training.

De-identified images used for training are kept separately from your email address. The only link back to you is a random code, which we keep so that we can delete your X-rays if you withdraw.

Which X-rays are used?

Only bitewing and periapical X-rays from adults. Panoramic X-rays and photos of teeth are stored but never used for training. We never use X-rays of anyone under 18.

Who can see my X-rays?

A small number of toothcheck staff who run the training work, and licensed dentists working with us (in Spain) who mark up X-rays so the tool can learn from them. They see the de-identified image, not your name or email. We do not sell your X-rays or share them with insurers, advertisers or your dentist.

How long do you keep them?

We keep contributed X-rays for [RETENTION PERIOD], or until you withdraw, whichever comes first.

How do I withdraw?

Every email we send about your X-rays has a withdraw my X-rays link. Click it and confirm, and we delete the X-rays you contributed and remove them from our training data. You can also email support@toothcheck.io.

Withdrawing doesn't affect anything you've already received, such as our X-ray reading guide. If a version of our tool has already been trained, it can't "un-learn" your X-ray, but your X-ray won't be used in any future training.

Will you tell me what my X-ray shows?

No. Our AI X-ray scanner isn't live yet, and nobody reviews the X-rays you contribute. This is not a diagnosis. If you'd like a dentist to look at your X-ray, see our dental X-ray review.
