Need help with emergency dental work

I live on Social Security an am barely getting by without major emergencies. I do not have dental insurance.

I’ve had 1 tooth break off at the gum line and the tooth next to it had an abscess. The abscess was throbbing. It looked like the dentist was going to have to pull both teeth which would have cost $8500 for everything. I had to go ahead and have the work done as I was in constant pain.

It turned out that the dentist pulled the tooth that broke, did the implant on the right side of the bone and a bone graft on the left side as that was needed. On the 2nd tooth he was then able to go into the root surgically and clean out the infection and fill that.

I now have to wait 6 months for the bone graft to heal before getting the crown.

So far the charges are $3900.
The crown will cost $1800
Subtotal is $5700.
Paid already: $1700

I need to raise $4000. I need $2200 of that ASAP as the work has already been done.  The $1800 for the crown is needed in 6 months. I will pay for the crown as soon as I get the funds. Every cent of what I raise will go to the dentist. (If I raise more money than I need, I will use it for non-emergency dental work that I've been putting off.)

If you can help I’d be forever grateful.
