I want to express my gratitude to Dr. Tsybulin I.! You are a professional! I had a terebration pain that kept me awake. I had a lot of cavities. To say I was scared is to say nothing! Of course, before the medicine was not like modern one that’s why it’s scary for me to treat my teeth. Now there is no fear! And also, I really liked the way you communicate with patients. I always pay attention to it, it is important for me! Thank you, Ivan Ivanovich!!!!!
