It will be 'analgesia-inhal of nitrous oxid' so it's not 全麻. I didn't get the x ray but they showed me a copy of suggested treatment (and costs) with a diagram of the teeth, with indication which teeth need filling and which need crowning. It will take 2 visits to finish all the treatments.
I am so silly... I was thinking to show the paperwork to another dentist for 2nd opinion! It's better to just pretend taking my kid for check up as a new patient!
Thanks for your advices. BTW are you a doctor, Dr. Phil?
