Extremely sore gums but no dental insurance...what can I do in the meantime?

I have a history of periodontal disease. I try to take care of my teeth as much as possible with brushing, rinsing and flossing. But unfortunately my bottom front teeth are quite crooked leaving somewhat large spaces for my gums to become more infected. Right now I do not have dental insurance and my gums are killing me! They are very inflamed and I have some prescription rinse but can only use it every so often otherwise it turns your teeth brown. Is there anything else I can do in the mean time to sooth my gums? Also, a weird thing too...I seem to get some sort of relief (or I'm just making it worse) by sticking my nail inbetween my teeth as if they're too scrunched together. Strange I know but I'm wondering if it's my teeth or it really is just my gums being inflamed.
