He is very nice to kids. We have Delta Dental Insurance of Massachusetts, which is supposed to have good coverage. However, for all the fillings did in his office, the insurance company said were beyond the coverage. We ended up paying very expensively for over 80% of costs out of our own pocket. The terms are so technical that it is hard to know why the treatments has to go so much beyond insurance coverage every time. Even with all the money, my kid is still bothered with her tooth a lot, especially the crown he put on her.
