The day you think you know it all... you're in trouble!

From the Charleston (SC) Post and Courier, "Veterinary medicine is a humbling profession."

For context, here's a photo of the mouth gags to which the author refers (from Roots Vet Dental Supplies):

We do own some of these instruments, but they are sitting in a drawer somewhere, in a sterilization pouch, covered in dust. I remember when we stopped using them altogether- I believe it was before the 2014 study cited in the article, and as I recall, we made the change less because of empirical evidence and more because of an intuitive belief that they seemed unpleasant. I also remember hearing about that study and being excited that there was some support for our touchy-feely conclusion.
