Nearly four hours after the last injection of novacaine, the feeling is returning to my lips. They're still rubbery, and trying to bring my teeth together feels like clacking castinets, but I think I've crossed the threshold.
I think it took this long due to getting a larger than usual dose. My upper teeth took longer to get numb, supporting my experience over a decade ago when a dentist ended up pulling one of my molars with almost no pain killer since he couldn't get the novacaine to work. Thankfully, this time there was enough effect that I didn't really feel the probes when she was planing the roots.
I have to go through this again next week for the right side, but then things should settle down again. Watching her 'inject' the militarized tetracyclin was a hoot. Little hooked turkey basters full of the drug, on the end of a big steel plunger. I nearly laughed when I saw that.
