It could mean the girl finds him to be caring, and could even like him.
hey I'm pretty sure if he gives you half a smile then he thinks you're cute and might like you.
There could be something in your teeth or he could think you have a beautiful smile. If he says it kinda sarcastically then you should probably check your teeth in the mirror.
Obviously it means that he finds you cute. Most guys don't run around telling girls how cute they are, so if he tells you that it probably means he likes you a little more.
It means he really likes you or accepts you as a friend
If a guy tells you are pretty u are.
If they're cute- smile and wink back. if they aren't- just smile.
Depending on what kind of guy he is he either really fancies you or he wants to get you into bed.

Not a thing
When a guy tells you that your smile is a turn-on, especially if he likes you, he's expressing attraction and appreciation for your positive energy. It suggests that he finds you physically appealing and enjoys the way your smile lights up your face, which can create a sense of connection. This compliment often indicates that he feels comfortable around you and is interested in pursuing something more than just friendship.
