Am I being shallow?

Okay ladies - I 37F Went on a nice date with a recently separated father of 1, 38M. The date was good, conversation flowed well. I enjoyed the time with him. However - he has bad teeth. It looks like he hasn’t been to a dentist in 10+ years. He admitted to formerly being a smoker, an avid marijuana user and energy drink consumer. He sent me a picture of himself yesterday and I can’t get over the brown crud in his teeth. It’s a turn off and I’m struggling with this being the reason why i don’t go on a second date. He took me on the nicest first date I’ve ever been on and I’ve dated 10+ men in the last year. What would you do

Update: I told him that I did not want to proceed with a second date and he did not respond well. I dodged a fucking bullet. Thank you all for the support and reassurance. Onward to hopefully a dude with acceptable hygiene
