You know, I feel your pain. Two weeks ago, I went to the Dentist's office and had a cavity drilled and filled. Unfortunately, I think he did a bad job because now, my tooth hurts (the same one). I live in South Korea and am fluent in English and Spanish, but not Korean (low-beginner). I am scared as tomorrow I am going to a new dentist and am figuring out how to tell him the other one screwed up. Boy are my teeth sensitive right now!
