Why we photograph your teeth (and what those photos are really for)

They are not for social media. Photographic records are a diagnostic, comparison and communication tool: here is how we use them.

Almost everyone asks the same thing the first time: «why are you photographing me?». It is a fair question, and the answer has nothing to do with marketing.

A diagnostic tool, not a keepsake

A standardised clinical photograph shows details that escape the naked eye inside a mouth: an enamel crack, asymmetric wear, the exact level of a gum margin, the real colour of a tooth compared with its neighbours. Magnified on screen, the same situation reads far better.

Comparison over time: the real value

This is the most important and least intuitive use. Changes in the mouth are slow: gum recession advancing slightly each year, enamel wearing down, a tooth gradually rotating. Nobody notices day by day, not even us.

Two standardised photographs taken some time apart turn an impression into data. It is the difference between «it looks worse to me» and «look, this margin has moved by this much».

Communicating with you

Being told «you have recession on the canine» is abstract. Seeing it on screen, magnified, is another matter. Most people make better decisions when they see their own situation, and they also understand why a particular treatment is recommended.

Case planning

In orthodontics and aesthetics, photographs feed directly into the plan: the proportions of the smile relative to the face, the lip line, how much of your teeth shows when you speak. That information cannot come from a scan of the arches alone, because it concerns the relationship between teeth and face.

What about privacy?

Clinical photographs are personal health data and are treated as such: kept in your clinical record with the same safeguards as your other data.

One point we want to be explicit about: using your image for purposes other than your care — teaching or public communication, for example — requires separate, specific and revocable consent. It is not covered by consent to treatment. If you do not give it, absolutely nothing changes in your care.

What we ask during the shoot

Just a few positions: natural smile, mouth open, arches closed from the side. Retractors and mirrors are used — they are not comfortable but they make the photograph comparable over time. It takes a few minutes.

Frequently asked questions

Can my photographs be published?

Only with separate, specific and revocable consent, distinct from consent to treatment. If you do not give it, nothing changes in your treatment pathway.

Why do you use retractors?

They make all surfaces visible and, above all, produce images comparable over time: if the framing changes each time, the comparison loses its value.

Do photographs have to be retaken at every visit?

No. They are updated at useful moments: start of treatment, intermediate phases, completion, and later check-ups when a change needs assessing.
