The first impression is very fast, I think qualitatively. But I treated 1 tooth in the end, after the intervention of this doctor, I did two, the second was eventually healthy. And the one who was sick, she just didn't want to open it and redo it, after complaining that he was sick! then when I went to another dentist, they opened it for me and there was inflammation, they cleaned it badly for the first time, as it turned out. In general, I would not recommend this doctor. This is not a professional!
