Dear Self: BRUSH ALL THE WAY BACK. Do I have to time you?

I got my first cavity. My dreams for perfect teeth are ruined. ;w; There's even one developing on the opposite side... I'm 18! This shouldn't be happening! At least fillings aren't metallic like they used to be

DISCUSS. How bad will it hurt when they take it out? What does this cavity removing process entail? Is it time to start fearing the dentist? At least one of you guys must have had a cavity removed ;o;

( With that aside... )
