British people, psychologically, what do you think of someone who never shows their teeth?

Not much...

I dont think anything. Not everyone goes out of their way to show their teeth lol

no teeth , dont matter ,if good person,

They got bad teeth

Not everyone's teeth naturally show.

They might have bad teeth or no teeth.....or they might just be self-conscious about their face & mouth.

they aren't going to attack you?

Japanese consider showing teeth as an animalistic sign of aggression

Me 💔😞
