Root canal

I have a question. So my root canal is booked for June for a tooth that got filled two years ago. But the thing is I have a bump in my gums that hurts ontop of that tooth. And I feel like waiting until June is dumb and might cause a bigger infection or something. The dentist I’m going to is a public one which is why it’s at June. But should I just go to a private one and pay it full to get the root canal done earlier because I’m scared it might grow or something.
