I know I have a mess of cavities, but the last time I went to see the dentist I panicked. Things have changed since when I was a kid, the procedures seem different. They tilted the chair WAY back and that panicked me. I remember in the past they didn't tilt one back that far. I thought 'I will choke on my own saliva' and decided against doing this.

Also when I was younger nitrous was less expensive so I could afford to have nitrous. I can't see how anyone could sit there and do this stuff stone cold sober.
