How to whiten teeth in a photo
Learn how to whiten teeth in photos without changing the smile. Choose a clear portrait, adjust tooth color and review edges, texture and lighting.
Step 1. Upload a clear person photo
Choose a portrait with visible teeth and a readable smile. Upload one JPEG, PNG or WebP up to 30 MB. A closed mouth leaves no visible teeth to whiten.
Step 2. Add instructions if needed
No prompt or reference image is required. The default gently reduces yellow tooth tones. Use Edit instructions for a subtler result or to identify one person in a group.
Step 3. Generate your preview
Check the displayed credits and click Generate. Each submission creates one image. Loading an example only fills the form and does not start generation.
Step 4. Check the smile, not just the shade
The goal is a small tooth-color edit. Generative editing can shift details, so compare the result with the original before keeping it. Check that tooth count, shapes, alignment and gaps still match the original. Look for retained enamel detail and shadows between teeth rather than a flat white strip. Compare mouth opening, lip corners and gum line. Whitening should not create a bigger smile. Check skin tone, scene warmth and any other person's teeth for unintended changes.
Choose a readable smile and modest adjustment
Use the original photo and describe the tooth-color change you want. Keep the request focused on whitening.

Start from the original and ask to retain tooth edges, gaps and alignment.
Texture and shadows
Look for retained enamel detail and shadows between teeth rather than a flat white strip.
Ask for subtler whitening and retained enamel texture and inter-tooth shadows.

Teeth whitening photo editor questions
How do I whiten teeth in photos?
Upload a clear photo with visible teeth. Leave Edit instructions blank for subtle whitening or describe the strength and target person. Generate, then compare the smile and tooth detail with the original.
Do I need a prompt or a reference image?
No. A Person photo is enough for the default edit. Edit instructions are optional, and this tool does not require a second image.
Will it change my smile or straighten my teeth?
The edit is instructed to adjust tooth color while retaining tooth shapes, gaps, alignment, lips and expression. It does not straighten teeth, add veneers or create a new smile. Review the result for unintended changes.
Can I whiten teeth in a group photo?
The default targets the most prominent person. For a specific person, name their position or clothing in Edit instructions, then check that other people's teeth stayed unchanged.
What if my mouth is closed or my teeth are blurry?
The tool is instructed to leave a closed mouth unchanged. Use another original with clearly visible teeth if the mouth is covered, tiny or blurred; whitening cannot reliably recover missing detail.
Can I make the whitening less intense?
Yes. Write 'Gently reduce yellow tones; keep a natural ivory shade and the shadows between teeth.' Compare at the original size before downloading.
Does this change my real teeth?
No. This is a digital photo edit, not a dental treatment or a prediction of treatment results.
Does loading an example use credits?
No. It only fills the form with the source photo and instructions. Generation requires a LumiYing account and uses the credits shown before you generate.
