Concern) Worry about gaps between teeth..

I am worried about the gap between my front teeth.

I am usually afraid to speak in front of others.
The reason is simple. When I was young, there was about a 1.5 millimeter gap between the front teeth that were replaced, and I didn't want to show it.
And among friends, stories about teeth, like how lucky someone is, are occasionally brought up.
It's just something I could ignore, but hearing that phrase once, twice, or multiple times made me become somewhat conscious of it.
I think that comment will come up again, so I try to keep my mouth shut and speak as little as possible.
This is a dental-related trauma that I have had since I was young.

Now that I have achieved a certain level of social status, I become even more conscious of this part of my teeth.
Everyone else is doing it, so I think about getting braces, but I can't because of various reasons, and after deciding to do it, I end up procrastinating and letting it pass.

Has anyone ever enlarged their teeth to cover gaps instead of pulling them left or right?
To get braces, I need to have wires in my mouth, and it seems like it will take a lot of time. I am considering this method and keeping it in mind.
How long does it take to do it this way, and do I need to worry about it being weak or fading?
Since there is no device placement after the test, we don't need to consider the duration separately, right?
What is the approximate price range?

I'm thinking it would be good to install this device now, so I'm posting my 고민글 (thoughts/considerations).
Please let me know if you have any experience to share.
Have a comfortable holiday~~
