So the dentist I went to for over 10 years was just some fraud? Hmmm, I should get the crown she put in looked at then, since the all-knowing edog said she's not worth her salt.Any dentist worth his salt should laugh in your face if you ask for nitrous for a teeth cleaning. That's like asking a dr to put you under so he can take your blood pressure.
Just because *you* have not encountered a dentist who understands fear and anxiety does not mean they do not exist.
And to top it off, your analogy is poor. It's more like being mildly sedated to draw blood.
