Do teeth need to be perfect for them to be cute/attractive?

I have teeth with cavities on them, but I'm more asking because of other people who have insecurity about their teeth. Like my friend has a gap in their front teeth, but I think it's unique and looks cool. My boyfriend has some slightly twisted or abnormal teeth, I think they're so ridiculously cute & make him more attractive.

I've also seen in Japan it's a trend to make your fang teeth poke out? Other people say bad stuff about it, but I think it's cute tbh.

This isn't the first time I like traits that make people look unique, or traits commonly considered unattractive. So I'm just curious about what everyone else thinks, what are attractive teeth?
