Would I need to get braces again to fix my one crooked tooth or are there other options for me? (Photos)

After I had my braces taken off I had retainers but lost them after the first month. Consequently, my front left tooth as shifted forward. The rest of my teeth seem fine but I want to correct this one tooth. I'd rather not have to go through the hassle of braces again nor do I have the money for them. Any options or help would be appreciated!
