When I was a child I believed cavities were things that happened around the time that my mother was a child, and no child had cavities in modern times. This happened because people back then didn't know how to brush their teeth, and in modern times everyone was smarter. I believed it until I was 15, and had my first cavity. I felt really bad and asked the dentist if he did fillings in young people.
