when i had general tooth cleaning with mischuk i had a great deal of pain. on simple fillings i had a lot of pain. But when I had a root canal with him I was put through the greatest amount of pain that I had ever experienced in my entire lifetime. He did not stop the procedure like any normal dentist would have. When I came back for the 2nd stage of the root canal I had tremendous anxiety. I have since moved on to a different dentist.
