Dr. Druian recently filled a few cavities for me. One of the cavities was quite deep and I was concerned that it may turn into a root canal. Luckily the procedure went smoothly and the nerve was not interrupted. He was so quick and had the most up to date technology. 1 week later and the cavities that have been filled are not giving me any problems at all. I have had no sensitivity from the very beginning. He works inside the the London Centre for Cosmetic Dentistry with Dr. Spektor who did an adjustment for me on one of my teeth and he also seemed very nice. Great receptionists up front as well. Highly recommend for cosmetic dentistry because they do an excellent job.
