After a particularly trumatic experience with an emergency dentist, I had some serious adult-baby issues to work out. After several especially embarassing appointments, I requested the gas. For an extra $30, it relaxed me completely. The best part is that the relaxing experience seems to have reset my mind, and I'm now much more comfortable at the dentist without it.
btw- you probably don't want to watch
