Braces?

I’m 27 years old, I’ve always hated my smile mostly because I have one ugly snaggle tooth (the one next to my top right front most tooth is about half way tucked behind the front most). I was told around 12 years old I should get braces, but my family was poor and we couldn’t afford it.

I’m getting married in September of this year. Should I get braces or should I get those invisible liners? I want to feel pretty on my wedding day, not like a teenager. But I heard braces work better and faster than the liners.
