Are they definitely rotten? Or is it where they're overlapping etc? He seems a nice guy, I think they're just awkward where they're each others firsts. Sometimes when he kisses her on the head its like it doesn't come naturally, and he properly goes for it like a cobra
Should have been picked up as a child and had braces imoBut he is in Scotland so there is a price cap on treatment that it can’t go over no matter how much you need done. This includes dentures. It can’t be just only cosmetic his teeth are rotten they will all need out soon anyway. He could also go to a dental hospital where they would do it for free. Plus all check ups are free.
