My current (private) dentist in Moscow has a way to assuade concerns like this which I find quite interesting. From the first visit on, you have a personal profile that you can open in an app and their website which contains a detailed (not dumbed down) log of everything they did, as well as high-resolution photos, videos and x-rays of the procedures. They're happy to do diagnosis and have you get a second opinion with the raw data they collected before doing anything.

I showed this to my mum who lives in a different country and has been having lots of trouble with dental surgery lately, and she was very surprised by it. I also haven't seen anything like this anywhere else before.

Another fun part was that while doing something they have a screen on the wall that shows the feed of the instrument-mounted tiny cameras, this lets the assistant see the view that the doctor has. They also have a ceiling-mounted screen you can see which was just showing random Youtube videos or TV or something, so I asked them if they can put the camera feed on the ceiling-mounted screen and the doctor immediately said "You work in IT, right? Only tech people ask for that."
