Before-and-after photos, and what they do not show

This guide covers travel, process and cost. It contains no clinical advice.

Photographs are the most persuasive thing on a clinic's website and the least verifiable. Lighting, camera angle, lip retraction, head tilt and post-processing all change how a smile reads, and none of them involve dentistry. This does not make galleries useless — a large, consistent, honest gallery is a genuinely good sign. It means you have to read them as evidence of a certain quality rather than proof of an outcome, and there is one request that separates the two.

Six things to look at in any pair

None of these six means a clinic is being dishonest. Most clinics photograph the way every clinic photographs, and the flattering conventions are simply the conventions. The point is to read the images knowing that, rather than to treat them as measurements.

The one request that settles it

Ask to see a case photographed at twelve months rather than on the day the work was fitted. Gums recede and settle in the months after treatment, and a result that still looks right a year later is showing you something a fitting-day photograph cannot. Clinics that keep long-term records will have these; clinics that do not will say so, which is also information.

Ask alongside it for a case that started where you are starting. A gallery full of straightforward cases tells you nothing about how the clinic handles a difficult one, and if your case is difficult that is precisely what you need to know.

What a good gallery actually looks like

Unremarkable, mostly. Consistent framing and lighting between before and after. Cases of varying difficulty rather than a highlight reel. Some results that are good rather than dazzling. Occasionally a case with a note about a complication and how it was handled — which is the strongest single signal a gallery can carry, and almost nobody publishes it.

Read it the same way you read reviews: the pattern matters more than any individual entry, and uniform perfection is less convincing than honest variation.
