I have an anti-recommendation: Pin Ya Yi Clinic at 175 Cheng Gong Road in NeiHu (品牙醫診所 台北市內湖區成功路四段 175號). I went twice. (Once too many.) I do not remember exactly which service I got on which visit, so the chronology may be a bit off, but here's what happened.
On one visit, the dentist cleaned three or four teeth before he got around to mentioning that he was going to do a cleaning and was that okay? Okay, I said. One of my front teeth has a weak-looking cap, and I noticed that during cleaning he roughed it up several times. Guess he wanted to make sure that the cap would hold. It did.
When I showed up for my second visit, my appointment was nowhere to be found in their system. I should have taken the hint and left, but I didn't. I sat waiting for 45 minutes instead.
On the second visit he gave me a deep filling with no anesthetic. Rather painful since he was grinding right next to the nerve.
Another service I needed was to get a cap reglued. I produced the cap; the dentist said that he could reglue it, but there was no guarantee about how long it might hold. Faced with this lack of confidence, I started to tell him about the different kinds of dental cement, and that glass cement works fine and lasts a long time. I could tell pretty quickly that for some reason he didn't want to hear about it, so I went quiet. Maybe glass cement doesn't fit in with his business model. Anyway, he used his crappo glue and it held exactly 11 days, pretty much as he had predicted. I then went to a good dentist (Dentist Huang in YongHo, 黃牙醫， 永和市保福路二段101號 tel: 2922 7408), who uses good cement, and it has held for months, and counting. Dentist Huang, incidentally, is older, speaks Mandarin or Taiwanese, loves to explain what he's doing, and draws very nice diagrams to go with it. The guy's an artist. His prices tend to be lower, too. One slight shortcoming is that a nearby tooth may get whacked occasionally by some tool or other. No one's perfect.
Back to NeiHu, another thing I did not like about Pin Ya Yi was the one time he used English. While looking into my mouth he said, "God!" I would not hold this impropriety against him if everything else was going smoothly. With the right person, it might even be funny. But it wasn't.
Anyway, there is one very excellent thing about Pin Ya Yi Clinic.
I never have to go back.
