Me: “I’ve been using a water flosser for several months now. You showed me the x-rays you took before the cleaning and there were maybe two tiny spots of plaque under all of my teeth put together. While Denti-Cal now covers deep cleanings, I’m not going to do that when there’s absolutely no reason to. I’m sick and tired of being pressured and cajoled into all manner of questionably necessary, or flat-out unnecessary, procedures. No other dentist I’ve ever been to has ever behaved like this. I’m not coming back.”

(I actually didn’t come back this time, and when they called me six months later to remind me of my next appointment, I told them again that I was never setting foot in their door.)
