Whiten Teeth and Enhance Smile in Photo

📸 INPUT REFERENCE: Use the uploaded photo as the base — preserve the subject's exact facial structure, expression, pose, skin, hair, clothing and background precisely as they appear in the original 🦷 TEETH ENHANCEMENT TASK: Naturally whiten visible teeth by removing yellow or grey discoloration, while keeping a realistic off-white tone — never pure bright white, which looks artificial. Subtly correct minor visible chips, gaps or misalignment only if specifically requested, otherwise preserve the subject's real natural tooth shape and arrangement 😊 SMILE REFINEMENT (only if requested): Slightly soften an overly forced or tense smile into a more natural, relaxed expression, or enhance an already natural smile's warmth — without changing lip shape, mouth width, or facial structure 🔍 NATURAL DETAIL PRESERVATION: Maintain realistic tooth texture, natural light reflection and subtle tonal variation between teeth — perfectly uniform glossy white teeth look fake and must be avoided 💡 LIGHTING CONSISTENCY: Match the lighting direction, shine and shadow falloff inside the mouth area to the rest of the face so the correction looks seamless and unedited 🖌️ STYLE: Photorealistic natural retouching — subtle, magazine- editorial level correction, not an artificial filter look 🚫 IDENTITY PRESERVATION: Never alter lip shape, mouth width, jaw structure, or any other facial feature — teeth color and minor smile warmth only 📐 ASPECT RATIO: Preserve the original photo's exact aspect ratio and framing
