The fastest dental pick in all of Richmond.

I've always been slightly perturbed by how quickly my dentist looks at my mouth before considering it cavity-free; while I'm not in favor of my mouth containing cavities -- especially since it's currently unfillinged -- it seems as though he ought to spend just a bit more time making sure it's all a-okay. Today, I decided to time him. I started mentally counting a quick "one-one-thousand" after he told me to open my mouth, and by the time he had taken his tools out, I was only at "six-one-thou..." Am I crazy in thinking this is not enough cavity-searching time?
