Today I saw a new dentist, near my house, for the first time in over 25 years. My wife made the appointment, after waiting (and waiting and waiting) for me to set one up for more than a year. Recent distractions didn't make it more likely, so I'm glad she organized it. Good news all around. My teeth and gums are all fine, and I have still so far avoided a single cavity in my life.
My youngest daughter was remarkably patient, waiting by the chair for the entire hour. (The overhead TV, with headphones and remote control, sure helped.) The dentist told me that if my gums hurt a bit after the cleaning, I could take some Advil. I told her there was no need—I'm on something much stronger at the moment after my recent surgery, and in comparison to that, dental cleaning is like a walk in the park anyway.
UPDATE: Let's be clear. This is the first time I've changed dentists in over 25 years. The last time I went to the dentist was the fall of 2005, not so long ago. Sorry for the poor phrasing on my part, and to Tod and others in the comments for correcting me.
