How to Straighten Teeth in Photos (Free AI Tool)

Love the Smile, Fix the Alignment

You have a great photo — the lighting is right, the expression is genuine, the moment is captured perfectly. But you keep staring at the crooked tooth or the small gap. AI photo editing lets you subtly straighten teeth without making the smile look fake or over-processed. No orthodontist required, and the edit takes seconds.

What the AI Can Correct

The tool handles common alignment issues that show up in smile photos: a single crooked front tooth, overlapping teeth that cast shadows, noticeable gaps between teeth, teeth that are rotated or angled differently from the rest, and uneven gum lines that make aligned teeth look crooked. It repositions and reshapes the teeth to look naturally straight while keeping the overall smile authentic.

Fixing a Single Crooked Tooth

One tooth that sticks out or tilts sideways draws the eye in every smile photo. Upload the image and describe it: 'straighten the crooked front tooth on the left side.' The AI adjusts the angle and position of that one tooth to align with its neighbors. The rest of the smile stays exactly as it is. This is the most common fix and produces the most natural results.

Closing Gaps Between Teeth

A visible gap — whether it's a diastema between the front teeth or spacing further back — can be reduced or closed entirely. Describe the edit: 'close the gap between the two front teeth' or 'reduce the spacing between the teeth.' The AI shifts the teeth closer together and fills in the dark space naturally, matching the surrounding tooth color and texture.

Fixing Overlapping or Crowded Teeth

Overlapping teeth create shadows and uneven edges that are hard to ignore in close-up photos. Tell the AI: 'fix the overlapping teeth on the bottom row' or 'make the crowded front teeth look more even.' The AI separates and aligns the overlapping surfaces, removing the shadows and creating a cleaner tooth line. Works best on front-facing smile photos where the overlap is clearly visible.

Keeping the Result Natural

The goal is alignment, not perfection. The AI straightens teeth while preserving their individual character — slight size differences, natural color variation, and realistic edges. It does not produce a Hollywood-veneer look unless you specifically ask for it. The result looks like good genetics, not an obvious edit.

Tips for the Best Results

Close-up smile photos work best because the AI has more pixel detail to work with. If the teeth are small in the frame, crop to a headshot first. Be specific about which teeth to fix: 'straighten the two front teeth' is better than just 'fix the teeth.' For multiple issues (crooked plus gaps), address them one at a time for more precise control. And combine with teeth whitening if needed: 'straighten and whiten the front teeth.'
