Another day, another dentist attack! Got some more fillings, and a root canal. It took a lot longer. Possibly because I complained about my jaw aching from the bite-blocker, and they gave me several breaks. Also possible because they had to use microscopic files to excavate my teeth to a depth of about 1.1 meters. Took about ninety minutes for the two fillings and the root canal. They used temporary fillings on the root canal because some time is needed to tell if the results are good, upon which they'll clean that out and permanently fill and crown that tooth.
Feels pretty weird right now, and I have a headache I'm pretty sure from the jaw-torquing and whatnot. And the numbing.
