YOU'RE AT THE DENTIST'S; "And it looks like you're all good! No cavities whatsoever!"; "Except this big one right in the middle of your molar and it looks like its going to be a root canal, plus the gums nearby look really swollen so we won't be able to numb you and if we don't do something in the next 5 hours your other teeth will most likely need drilling as well."
