It can be fixed. I have fixed my teeth, but it depends on how deformed your teeth are.

If it's the row of teeth in front of the door, I need to pull in two teeth in the innermost and top row of my mouth to make room for them, and then put on braces. Correcting teeth is a hard process. During that time, my digestion was affected, and I often had to clean up the food stuck to my braces, which was disgusting.
