My mouth turns to the left side while smiling and talking. (Photo)

Thank you for sharing your question.  It would take a thorough in-person examination to offer the best advice but it is not uncommon to have one side of the mouth that is stronger, or pulls more, than the other while animating. This is totally normal and does not require treatment.  Hope this helps.

Hi Tabrez12,
Since you only have one photo, we really cannot evaluate your concern but generally, this can be caused by asymmetric pulling of the muscle on the angle of the mouth. It may be improved temporarily by botox injection.
