Approx. How much is teeth cleaning under general anethesia? see details...?

I'm 53 yrs old. It's been 10 yrs since I had my teeth cleaned, and they're AWFUL. No lectures please; but I'm heavy smoker, and drink gallons of coffee and merlot - yeah, ugly :( Last time, it took 7 shots of novocaine to each quarter of my teeth, and I still had skull-shattering pain. It took 4 agonizing sessions, too. I can't go thru that again (I'd rather get dentures!) Incredibly, I have no cavities that I'm aware of or can sense, have no fillings. I have no dental insurance, so how much would it cost to have all my teeth cleaned in one session AND under general anethesia? Can it even be done this way? Thanks so much for your input. This would be in the N. Ohio area, if that's pertinent?
