How can i stop being so shallow with looks?

This guy is showing me a lot of interest and we are getting to know each other, but the only thing i don’t like is his teeth. I know its shallow but i can’t help it. I keep telling myself looks don’t matter but it beats me up inside. His teeth aren’t yellow or anything its like he has shark teeth or something its hard to explain but How can i make this work and stop worrying because he seems like the right guy for me so far? please don’t comment anything negative i’m being honest 😭
