Lymph nodes from bad teeth?!

Im 16 years old I have swollen lymp nodes under my jaw (more than one on each side), on like on my left jaw, 1 right under my chin, my throat on both sides, below my ears and a few scattered around the back and sides of my neck. Also recently felt like a few very small lymph nodes in my armpits and have had some in my groin area for a while now, more of them on the right side than the left. Im really scared that I could have all kinds of stuff going on. What scares me most is that I had chlamydia a while back and got checked for aids and came out fine but they said that I should get it done 6 months after I have not gone, hopefully it has nothing to do with HIV but ill have to go this month some time. They really arent painful at all but they are just there, they are hard and painless unless squeezed real hard or pressed on. This also scared me because I heard lymph nodes should not be hard and painless. Should be achey and tender, that hard nodes could be a sign of lymphoma. I have yet to get diagnosed, no money no insurance yet. I had 4 badly infected decayed teeth. 2 on each side, i got 2 removed from the left side now there is 2 left on the right side. I have had these serious infections in my mouth for years (probably 5or6) and never ever went to the dentist or a doctor till recently. Used to suffer from toothaches, but no more, their just rotten infected pieces of teeth. Hopefully Im on the road to oral health and hygiene. I also have super inflamed tonsils i have had them like that for a long time also probably 4 or 5 years. I had various abcesses that have been treated, do you think that highly infected decayed teeth and super swollen nasty looking tonsils can cause lymph nodes in the armpits and groin area? The neck and head area is obvious.
Thank you
