So, if I have this straight, to fix a cavitation, one has to:

"After scraping out the inside of the tooth the dentist will attempt to disinfect the tooth and the canals to eliminate any source of infection. The canal is then filled with a combination of cement and Gutta Percha in an attempt to completely occlude these canals. This is supposedly to prevent any microorganisms from entering the tooth either through the crown or the root. "

So they have to cut you open and clean you out and then pack you with stuff? I thought you said they weren't supposed to put anything in there?

How much does all of this cost and is it painful and how long does the surgery last?

Thanks a bunch, I appreciate the feedback.
