Urgent Dental Help Needed for a Caregiver

I am trying to get the money together for snap in dentures because my teeth are very soft and prone to cavities; i also have an infection that we’ll not go away despite two rounds of antibiotics so now mouth is a ticking time bomb; the reason I haven’t been able to save enough on my own is that my wife just had double transplant, so for the last 5 years I’ve been her lead care taker until now that she is finally starting to do better; I have asked family but no one can help and a loan is not the best option because it would be 10.99 interest rate over 12 years for me to afford it; my insurance will only cover 1,500 dollars because they have a cap; at this point anything helps; thank you.
