Teeth Whitening

ROLE
Act as a senior professional photo retoucher, portrait retoucher, beauty editor and AI image-editing specialist. Perform a controlled, production-quality dental appearance enhancement of the uploaded photograph. Treat the source image as the ground truth for the person's identity, facial anatomy, teeth, smile, skin, lighting and photographic characteristics.

EDIT
Naturally whiten and brighten the visible teeth of the main human subject while preserving their exact original tooth shapes, sizes, spacing, alignment and smile. Reduce yellow or dull discoloration and create a cleaner, brighter enamel appearance without making the teeth unnaturally pure white, artificial, redesigned or veneer-like. Preserve everything else in the photograph.

PRIMARY OBJECTIVE
Execute the requested "Teeth Whitening" edit convincingly and photorealistically. The finished image should look like the exact same person with naturally brighter, professionally whitened teeth rather than digitally painted white teeth or a completely redesigned smile.

The improvement should be clearly noticeable in a direct before-and-after comparison while remaining believable under the original lighting conditions.

EDITING PRIORITY
1. Preserve the exact shape, position, alignment and structure of every visible tooth.
2. Produce a clearly visible but natural whitening improvement.
3. Preserve realistic enamel texture, translucency, highlights and shadows.
4. Preserve the person's exact facial identity, lips, mouth and expression.
5. Leave everything outside the teeth completely unchanged.

QUALITY CONTROL
Before finalizing, inspect the entire image and verify that:
- the subject remains exactly recognizable;
- the smile and expression remain unchanged;
- every visible tooth retains its original shape, size, position and alignment;
- the teeth are noticeably brighter than in the source image;
- the final shade remains naturally believable rather than pure white;
- realistic enamel texture and translucency remain visible;
- natural shadows between teeth are preserved;
- highlights correspond correctly to the original lighting;
- lips, gums and mouth structure remain unchanged;
- no teeth were added, removed, straightened or redesigned;
- no unrelated facial or environmental changes occurred;
- the result resembles professional photographic teeth whitening rather than digital white paint or artificial veneers.

OUTPUT
Return one polished final image only. Preserve the original identity, face, smile, tooth anatomy, expression, hairstyle, clothing, environment, framing, lighting and photographic characteristics. Modify only the visible teeth to create a clearly noticeable but naturally believable whitening result. Do not add captions, watermarks, borders, logos, interface elements or explanatory text.
