A dream about a patient's smile that stayed with me

Last night I dreamed I was cleaning a patient's teeth, and when I finished, they smiled—not a forced smile, but the kind that reaches your eyes. Their teeth were perfect, but that's not what got me. It was the quiet relief in their face, like they'd been holding tension for years and finally let it go. Woke up feeling like I'd actually helped someone, even though it was just a dream.
