Cheap Root Canal/Crown

Hello, sadly I don't have insurance but really need like 2 root canals, one or both of them may need to be a crown now due to how long I waited.. but I'm just trying to figure out what to do. I'm 23 and have no parent to really teach me. I got told about Care Credit but that's just a credit card. I know that helps with payment plans but just need a good place to go to.
