can a tooth infection go away by itself?

i have an infection on one of my back teeth. but its not a wisdom tooth. i want to know if theres a way to get rid of it without consulting a dentist. i have no dental insurance

There is no way that it's going to go away by itself. If you are talking about a cavity and you don't get it fixed soon it's going to turn into a root canal which is going to be a lot more expensive. So contact your dentist asap.
