Where can I find affordable dental care? I went to a dentist and they want several thousand dollars to pull a few teeth & fit a top denture.

Living on ssl, I just can afford what they want to fit me with a denture so I can eat solid food again. I don’t have any teeth that line up to chew with. I've needed this for several years now and it's just hard to enjoy life not being able to chew or smile. The left side of my face is starting to droop causing me to drool down my face. I have problems with depression and anxiety when I go out in to public. It’s very hard having people looking at my mouth or trying to eat in front of people as well. I just want hide in my room that I rent from my sister. I dread leaving the house period. Thank you for your any answers you can afford me.
