Fix teeth

I need 3 crowns done and one needs a root canal. Also I have 2 filling that in need to get. I had one filling fall out after I was a dentist so not sure what that needs. One tooth that need the root canal and crown hurt very bad and has got infected. Got meds for the infection from my DR. I though am on SSD and no money. Please if I can get money to pay for all this or at least half I will be greatful.

I went to a homeless free clinic but they will not take me since I have ins. I tryed to explain I have a medical problems that requires ins. The ins has dental but they change 1300 to 2300 for a crown and root canal even with ins.
