TESTIMONIALS

What patients say about our specialists

  • Last Friday I went to Roberto for emergency treatment of my tooth. You immediately feel that you are being helped by very knowledgeable specialist. He exudes a high degree of expertise and takes the time to explain everything very well based on pictures taken. He is also a very pleasant person. Together with his assistant, he forms a highly skilled team that performs quick and painless treatment with great care for the patient. In short, a very good and pleasant experience that I can recommend to anyone needing root canal treatment.
  • Had an appointment with dr. Christescu following a root canal treatment that came back again (inflamed and in pain) after 2 years. Had been walking with fear of my own dentist for a while, my new dentist then referred me to Endo En Zo. Could drop by for an intake immediately the following week. dr. Christescu explained well what he was going to do and gave honest advice. Because as it turned out, what? My old dentist wanted to redo the root canal treatment, Dr. Christescu told me that this was pointless, because I could undergo another treatment after 6 months. The 3d photo revealed that there was a fracture in my molar because my previous dentist drilled my canals too wide. Only option is to pull the molar. But after a clear explanation and having avoided a root canal treatment, I am more than relieved! I recommend everyone to immediately request a consultation here when in doubt!
  • My own dentist had referred me to this practice because of its skill in root canal treatments. Friendly welcome, and because the one before me was running out of time, several staff members apologized. Had a very pleasant experience with Dr. Cristecu who clearly described all the steps and procedures before and during the treatment.
