I was fitted for braces by Dr. Cohen in Jan. 2009 and wore them until spring 2011. I had an over reatained baby tooth Dr. Cohen assured me would not cause any problems and proceeded with treatment as nornal. At first I was very pleased with the results. However, just two years later after a checkup with my dentist followed by an appointment with a new orthodontist it became overwhelmingly evident I had been misinformed about my baby tooth. A month later and several thousand additional dollars in dental ware I am again fitted for braces. Needless to say I will never return to Dr. Cohen nor will anyone in my family who were previously under his care. I do not trust the professional opinion of this doctor.
