I know I've been lucky with my teeth, very few problems, certainly mainly less than I deserved considering the care I've given them.
I hate dentists. When and where I grew up, one went to the dentist only when there was a big problem. I think I went once in my teens. Then came the Army and I had 2-3 small cavities filled. There was one trip to a dentist in my 40's, ruined by a young know-it-all hygenist who lectured me on tooth care. Sometimes I'm humble, but not that humble.
Finally in my 60's I finally had a crisis--bad wisdom tooth which had to come out. After that I started seeing a dentist every 6 months. He was my ideal dentist: had no hygenist, did his own cleaning, silent, we exchanged no more than a couple sentences each visit. He retired, right when my other wisdom tooth started acting up. After a couple years I finally arranged to see a new dentist. On the morning of my appointment, half the wisdom tooth fell out.
I was impressed by my dentist's setup--the x-rays were displayed on a tablet computer, as was each procedure with its (high) cost. Though I didn't like the switch from taking a sip of water to rinse one's mouth to having a suction tube setup. Anyhow, I got a referral to a specialist for the wisdom tooth, which I used this morning. My dentist's office was able to email the xrays to the specialist's office, so they were able to extract what was left of the tooth without a prior appointment; total elapsed time maybe 40 minutes from the time I walked in the door. That's impressive. Perhaps less impressive is the multiplication of jobs in the field of dentistry, but that's looking a gift horse in the mouth.
