Extractions and Dentures advice

I’m lost. I was dx with a progressive chronic illness and malabsorption while I was really ill destroyed my teeth. I saw a dentist when a front tooth broke. They only took an exray of my front teeth and were booking me for two root canals and crowns. I didn’t go back bc they would have sucked me dry one tooth at a time. I’m past the point and looking at the steps for dentures before I can’t eat at all. Can anyone recommend where to go? I have zero insurance 😔
