Yes, but only slightly. Most passport photo rules require a neutral expression (both eyes open, mouth closed), and many applications are rejected for toothy smiles, squinting, head tilts, or exaggerated facial expressions that change how your features appear.
In most countries, a small, natural smile is allowed in a passport photo, but big smiles, open mouths, or showing teeth often violate passport photo rules and can cause your photo to be rejected. To meet common passport photo requirements:
Passport smile rules exist because passport photos are used for biometric identification, and a neutral expression makes your facial features easier to measure and match.
Big smiles can change key markers: like the shape of your eyes, cheeks, and mouth, making facial recognition less reliable and increasing the risk of a rejected passport photo.
That’s why many passport photo requirements ask for a relaxed, neutral face, with both eyes open and mouth closed, so the image stays consistent across border checks, visas, and identity verification systems.
Allowed? A slight, natural expression may be accepted if your features aren’t distorted.
Not allowed: Teeth showing, open mouth, exaggerated smile, squinting.
