Teeth Whitening Photo Editor

Stains gone, shapes kept, every other pixel where it was. Runs in the browser, free to start.

One laugh, two sets of enamel

A real run through the model this page uses, on a close-up where the smile fills the frame. Drag the divider and watch only the mouth move — the freckles, the hair and the light stay exactly where they were. Every output is AI-generated, so your result varies with your photo — treat this as a guide to what the tool does, not a fixed result you will get back exactly.

AI photo tool

What does this teeth whitening editor change?

It brightens the enamel in a photograph you already have and leaves the rest of the picture alone. It is a retouching pass on an image — nothing about it touches your actual teeth, and it makes no claim about them.

Image tool

Two failures are what make most attempts obvious. The first is the flat white block: paint the whole mouth one value and you lose the translucency at the biting edges and the soft shadow between teeth, and the smile stops looking like it belongs to a face. The second is bleed — brightness that spills onto the lips and gums, leaving a pale halo around the mouth that is visible from across a room.

Keeping the original tooth shapes, their small irregularities and the shading near the gum line is what separates a clean edit from an obvious one.

The pass runs on the Nano Banana editing model in the browser, with free credits to start. Upload the photo, the flow opens on image-to-image, and the credit estimate updates before you commit; a failed run is refunded automatically unless it broke the content policy. The source decides the ceiling: a shot where the mouth is open, in focus and lit well enough to see individual teeth gives the pass something to work with.

Teeth in deep shadow, a smile blurred by motion, or a face so small in the frame that the mouth is a few dozen pixels wide leave nothing to brighten cleanly.

How the retouch works

Upload a photo where the smile is in focus, say how bright you want it, and the credit estimate updates before you generate.

1 photo
Source shot in
No masks
To paint
Free retries
Failed runs

Shapes preserved

Same teeth, same positions, same edges and gaps — only the colour changes, which is why nobody can point at what was done.

Browser-based access

Runs in the browser with free credits — no retouching software, no brush masks, no account wall before you see a result.

The same targeted approach covers the rest of the mouth and the rest of the frame: straightening in the braces filter, a whole expression change in the AI smile generator, and damage repair in old photo restoration.

How to use

Clean up a smile in three steps

From one photo to a brighter frame, with the cost shown before you commit.

1

Pick a sharp smile

The mouth open, in focus, and large enough in frame that individual teeth are visible. That is the whole prerequisite.

2

Say how far to go

Ask for a natural shade that matches the light in the photo, or push brighter for a poster. Name it and the pass respects the ceiling you set.

3

Check credits and generate

Generate, then export. A failed run is refunded unless it broke the content policy, so a second pass at a different shade costs you nothing.

Who it's for

Who cleans up a smile

People with one good photo, people with a profile to fill, people printing something that will be looked at closely.

The one good photo

Everyone has a shot where the moment is perfect and the lighting turned the smile yellow. This is the pass that saves that frame instead of retaking the day.

Profiles and headshots

A work headshot, a team page, a dating profile — anywhere the picture is looked at closely, and a quick pass across the rest of the shot is worth the minute.

Prints and invitations

Wedding thank-you cards, graduation prints, a family photo going on a wall at A3. Print magnifies everything a screen forgives.

Answers

Smile retouching FAQ

Common questions about brightening a smile in a photo with Kavel.

No. This edits an image file — it brightens the enamel in a photograph you upload and gives you a new picture back. It is a retouching tool, not a dental treatment, and it says nothing about your teeth or anyone else's.

Only if you ask for a shade the light in the photo cannot support. The pass keeps the original tooth shapes, the gaps between them and the translucency at the edges, so a natural target lands cleanly. Push toward pure white on a warmly lit photo and the mouth starts to detach from the face — that is the ceiling to respect.

No — this pass changes colour only. Alignment is a different job with a different tool, and the [braces filter](/image/braces-filter) is the one that handles straightening while leaving the rest of the face alone.

It should not. The whole design of the pass is that everything outside the enamel comes back untouched — lips, gums, skin tone, hair, lighting, background. If a result shifts something else, run it again; the model is not deterministic and a second pass usually behaves.

An open smile, in focus, with the face reasonably large in the frame and light falling on the front of the teeth. What hurts: heavy shadow inside the mouth, motion blur, a face that occupies a tenth of a wide shot, and photos already crushed by heavy compression from a chat app.

Yes, and you can name who — say every person, or say the two on the left, and the pass follows. Larger groups mean each face occupies fewer pixels, so the practical limit is how big the mouths are in frame rather than how many people are standing there.

The estimate is on screen before you press generate and moves with the format and resolution you pick, so nothing runs unpriced. Failed runs are refunded unless they broke the content policy, and a new account starts with enough free balance to compare two shades on the same photo first.

It is the same retouch a photographer has done in the darkroom and then in software for a century, and it is expected at this point in commercial work. Where it gets sensitive is anything presented as documentary or evidential — a news photo, an ID document, a before-and-after in an advertisement — and those are worth leaving alone.
