How it works

Upload your portrait photo

Upload a clear, front-facing portrait. Good lighting on the face and visible facial features give the AI the best foundation for teeth alignment editing. JPG, PNG, WebP up to 7MB.

Expect: Simple corrections: 15-30 seconds. Complex gaps or overlapping teeth: may need 2-3 refinements to look natural.
Describe what you want

Type your instruction: 'straighten the teeth to look natural and even' or 'fix crooked teeth while keeping natural smile shape.' Be specific about maintaining natural appearance. No marking needed—the AI understands what 'teeth' means in portraits.

Tip: Add 'maintain natural tooth size and shape' to prevent the AI from making teeth look artificial or oversized

Quick answers

Do I need to mark the teeth before describing what I want?

No! For most photos, just describe what you want: 'straighten the teeth to look natural and even.' The AI understands what teeth are in portraits.

How do I straighten teeth in a photo for free?

Upload your portrait to EditThisPic, type 'straighten the teeth to look natural and even' in the prompt box, and generate. The AI automatically identifies and corrects tooth alignment while preserving natural appearance. Free to try with no signup required.

Is there a free teeth straightener that doesn't require login?

Yes. EditThisPic's AI teeth straightener is completely free to try with no account creation needed. Upload your photo, describe what you want, and preview the result free — purchased downloads are clean at full quality.

Will the straightened teeth look natural or obviously fake?

When you include 'natural' and 'realistic' in your prompt, the AI preserves authentic tooth characteristics like slight color variation and individual tooth shape. The key is not over-correcting—subtle improvements look more believable than perfect uniformity.

Can I straighten teeth in old photos or low-quality images?

Yes, but results depend on tooth visibility. If teeth are clearly distinguishable in the original photo, the AI can straighten them. Blurry or low-resolution teeth may have less precise results. Best outcomes come from well-lit photos where teeth are in focus.
