(20F) am feeling self-conscious about my teeth before my long-distance boyfriend (30M) visits. How do I handle this insecurity?

I’m feeling really insecure about my smile. My teeth are straight, but they aren't bright white and have some marks left from when I had braces. Even though I maintain good daily care, I still feel self-conscious about them and tend to cover my mouth when I laugh.

We’ve FaceTime’d many times over these 2 months, but I feel like the camera doesn’t show what they really look like in person. He’s always been good to me and gentle. I’m just scared he might be surprised or disappointed when he sees my teeth in person when he visits in 2 weeks

Looking for relationship advice on navigating this insecurity with him. What are the best ways to bring this up before his visit, or is it better to work through the feeling once he arrives?

TLDR: I’m feeling insecure about my teeth ahead of seeing my long-distance boyfriend in person. Looking for advice on whether I should mention it to him beforehand and how to handle the anxiety.
