The GumScout app

Read the trend, not the mirror.

Are your gums actually moving, or is it just the light? GumScout helps you find out by comparing like with like, once a month. Free for 2 check-ins, no account.

Four guided photos a month

Front, with both arches showing and the lips pulled back. Left and right, with the side teeth biting together and the cheek pulled back. And the lower front teeth close up, with the lip pulled down, because that is where recession most often shows first. A faint ghost of last month's photo sits on the camera so you line up the same way every time. Use the camera or your library.

An honest read

• A GumScout stage from 0 (no root showing) to 4 (long roots on many teeth), as a range with a confidence level.
• A Gum Score from 0 to 100 for each zone, where 100 is a gum line sitting at the enamel edge, so you can see direction over months.
• Signs the AI can actually see, such as root showing, dark triangles between teeth, a notch at the gum line, redness, swelling, deposits along the gum, or a bump on the gum, each marked possible or likely.
• A comparison with your last check-in, zone by zone: better, same or worse.
• What to watch and the signs that mean a dentist, not another photo.

One clear verdict

Looks stable, Keep watching, Changing, or See your dentist. A safety layer can only raise the verdict, never lower it. A bump or pus on the gum, swelling with bleeding, or a change within weeks always ends in See your dentist. Your first check-in is a baseline, so it can never read Changing, and the app waits for a 3-month trend before it leans on a change. One month is noise: light, the angle, how far the lip is pulled back.

A timeline that stays on your phone

Every check-in is saved with its photos, read and notes. One optional reminder arrives four weeks after each check-in. Compare any two months with Pro: hold the photo to flip between then and now.

A report for your dentist

Pro makes a one-page PDF on your phone with stages, Gum Scores, signs and photos for the last 3, 6 or 12 months, plus a short neutral note written for a dentist. Show it in the chair or send it before the visit. A consistent before-and-after pair tells a dentist more than memory does.

Free and Pro

Free: 2 check-ins (a baseline and one comparison), the timeline and the guide. GumScout Pro: unlimited monthly check-ins, Gum Score trends by zone, compare any two months, and the dentist report.
