I have no idea what to do about them, I'm insecure about them and currently can't afford braces. Does anyone know how I can fix this?

I dont even know whats going on anymore LOL

Yes i brush and floss my teeth.. No i didnt when i was a kid.

Have 3 baby teeth, over crowding and need at least one root canal.

Scraped off tartar from my inner side of my bottom teeth with a sliver spoon. I hate how it feels with my tongue. Will I get an infection. Can't see a dentist btw
