Desperate for dental work!!!

I am in real need of dental work. I'm 64 years old and my teeth are falling out as a result of the dry mouth side effects of a medicine I need and have been prescribed for two years now. My husband is 72 and retired and we are barely making ends meet. We have no money for dental work and as of recently it's become nearly impossible to eat solid foods. Please help me get my self-esteem back and be able to eat normal food. I am not a drug addict, just an older women down on her luck and very worried.

About a year ago I lost my first tooth. I was eating a hamburger. Within a month I lost the 2nd one. About 3 months later I lost the 3rd. Yesterday while I was talking to my son and his friend, the 4th one fell out. I don't know what to do!

If you can afford anything at all, I would really appreciate your help. Thank you so much.
