Any OT Experience with Grillz?

I've been thinking of getting some grillz for 2020. I'm asian-american, not hood, in IT and close to middle-age.

I always thought they looked cool and honestly want to get some to wear occasionally when hanging with friends and going out.

I'm debating about getting a set for fun, maybe spending maybe 5 or 6 hundred tops. Nothing real just some cheap gold and CZ. My main questions are about practicality, how they feel, how long do you leave them in etc.

There's a place here called Bling Bling that is supposed to be good but am scared to go in there as a noob. No one I know has ever worn them. Never seen anyone IRL wearing them either. Seems like it be fun to wear out a couple times a month.

Are these things comfortable at all? I boxed in high school and those soft mouth-guards kinda of sucked, I couldn't wait to take them out. I can't imagine a metal grill being comfortable.

Is a grill just something you wear for a few minutes while taking selfies or are they something you can actually wear on a date for several hours, can you eat and drink with them, can you talk with them in?

I realize the OT isn't really the demographic but maybe a few of you wore some as part of a halloween costume or something.

If you could actually just wear them like a retainer, maybe I'll get some but I don't want to go into the Bling Bling shop and get laughed off for asking this stuff.
