I'm seeking providers of dental services to the homebound. Any suggestions?

I would contact a skilled nursing facility and ask them for references, I have had good luck finding local resources using this route. After a few calls I took the staff a plate of goodies as a thank you. Now they all know me and are very helpful. Also remember to thank them for all they do in their jobs for everyone, it tends to be a pretty thankless vocation, even though it is such an important one. Good luck finding one that can do most everything at home.
