Yep, get a second opinion Earl. And listen, I am not trying to scare you or anything but Jim eventually lost all his teeth due to medications and such. His teeth started receeding and exposed the pulp.
All I am trying to say is get a second opinion. For Jim it was salvage what they could as long as they could. But I do think your dentist is charging an enormous amount. That's almost a down payment on a house at the right price! Wow.
You could almost get implants for that price, not to mention false teeth that look very real. Ha!
