What is when a guy says you have a beautiful smile?

When a guy tells you that you have a beautiful smile, it typically means that he finds your smile attractive and charming. It may also indicate that he is interested in you and wants to compliment you in a sincere and genuine way. This statement can boost your confidence and make you feel good about yourself. However, it is important to note that while compliments can be nice, they should not be the sole basis for your self-worth. It is important to love and appreciate yourself for who you are, beyond external validation from others.
