How can I "delay" the infection in my tooth?

I'm pretty sure my last baby tooth (on the side, in the middle-ish) is in the process of getting infected. It's not realy loose yet, just kind of wiggly. I have had infected teeth before, and the pain is terrible, and distracting. It also hinders eating habits. I can't go to the dentist, as we don't have dental insurance (nor will we for 80+ days) How can I delay the infection untill we can get it taken care of?

I use raw garlic it is a natural antibiotic.it stings like hell only for seconds, but it helps the pain.and brings down swelling..but u will smell like garlic for the rest of the day,but then u can chew gum.. :)
