After years and years of no cavities, my dentist found one lurking in my backmost upper molar that was the size of the Grand Canyon. The novocaine ensured I didn't feel anything, but it was still really unnerving to hear the drill winding its way into my tooth, and then seeing the pictures after. This is the first dentist I've ever been to who gives you these hugely magnified video tours of your own mouth.
I found it fascinating, and I wonder why every dentist doesn't do this.
As bad as it looks ("Doctor, that's like 60% of my tooth gone!"), he reassured me it was a relatively minor filling. I shudder to think what other peoples' fillings look like, and I know this will definitely get me to floss more regularly.
