1. The dentist I had in my 20's was terrible.
    Exclamations of, 'what happened here?' are not cool and sound expensive.
  2. I have exceptionally large and wide teeth.
  3. There's a lot more blood involved then I remember.
    Maybe my old dentist was doing it wrong?
  4. I prefer dental work to hurt a bit.
  5. I am congratulated on my good hygiene, but...
    Bad things do happen to good flossers.
