I need dentures bad, am a sole provider for myself and cannot afford insurance.

I am 55 years old and have had extensive dental work all my life. When I was in my early 40's I was bitten by a dog in my face, which caused a lot of damage to almost all of my teeth on the right side (both top and bottom)>I went through several surgeries, infections, etc. All of this happened when I had dental insurance. Eventually my teeth started to break and fall out and because I haven't had insurance since 2005 (when hurricane Katrina hit our home town) I now have broken teeth to the gum, unable to eat very much and haven't smiled in years not to mention the pain and my face sinking in. I have no self esteem, especially when it comes to job interviews. This really hurts me because I am in the medical field as a care giver presently but want to pursue other avenues. I am not asking for a handout- I simply would like to find an organization or someone who can assist me in getting my smile back.
