Dr. Cohenca and all the staff at Prime Endodontics were excellent! From the initial consultation to my treatment, every person I had contact with was so polite, caring, patient and professional. Dr. Cohenca was extremely thorough, he took his time and explained my problem using advanced imaging and discussed my two potential treatment options in copious detail to the point where I had absolutely no questions left. Because of his expertise, I was able to have an old (approximately 17+ year old root canal which became infected) treated within few weeks of my initial consultation, using the more challenging technique for the doctor but better long term results for me. My procedure was a total success with zero complications. They were extremely calm, patient and accommodating during my slight panic attack after receiving numbing injections (this has previously occurred at my regular dentist's office during a filling and I am now realized that I have a sensitive to lidocaine with epinephrine and will plan accordingly for any future dental work). I was able to go grocery shopping and attended my dental cleaning appointments within few hours of my root canal repair with no pain, swelling or complications. They provided me with Dr. Cohenca's personal cellphone number just in case I had any post procedural complications and called to check in on me the following day. I have previously been referred to a different endodontist who told me that he would not touch my root canal unless absolutely necessary due to how old it was and how complicated treating it would be. I am so glad my dentist referred me to Dr. Cohenca who was able to perform this difficult repair without complications. I am forever grateful and would absolutely recommend Prime Endodontics to anyone in need. Thank you!

Swift response in getting an appointment set up for a suspected root canal. Procedure was relatively quick and very much painless.The staff were professional, friendly, and mindful in alleviating any discomfort felt during the ordeal. I half-joke that the most painful part of the procedure wasn't the nerves or sharp pointy objects, just the costs!

Dr. Cohenca and his staff are exceptional. They go out of their way to make the patient comfortable throughout their appointment. Without saying their expertise is second to none. Dr. Cohenca is an expert in his field of dentistry to which I will refer family and friends to him in the event they are in need of his help.

Prime Endodontics team and Dr. Cohenca are very caring and professional. I had a swelling in my cheek and I have been referred by my dentist to their office. I want to say I had the most amazing root canal - Yes, there is such a thing!! I am now recovering and grateful to the team

Dr. Cohenca saw me for an emergency root canal right before I was going on vacation overseas. I was terrified but Dr. Cohenca carefully explained what he planned to do and completely made me feel at ease. The procedure was painless and I was comfortable under blankets with noise canceling headphones. He was fantastic and I've had no issues with my tooth. Dr. Cohenca is outstanding and I highly recommend him.

Dr. Cohenca is so kind and patient. My son had a very traumatic experience at a previous Endodontist. Dr. Cohenca was patient and explained everything to him. He made my son comfortable and cooperative. I can't say enough good things. He made both my son and I happy and confident again.

Karen at the font desk was amazing and was able to get my in same day for my intense tooth pain. They didn't have time for a full root canal but were able to go in and clean it which helped with the pain. Doctor Cohenca was very kind, patient with me and explained everything. The assistants he had was also very kind and patient. Was a lot better experience then the first place I went for my first root canal. Excited I found them and would definitely recommend!

My dentist referred me to Dr. Cohenca to assess a toothache that I thought was related to a previous root canal from a different endodontist . He found that it was the tooth behind it causing the problem and so I needed another root canal! I was nervous to get this done again, but Dr. Cohenca and his assistant Beth were so calm and kind during the whole procedure. It really didn't seem like it took that long. I received a text the next day to check in and he even emailed me photos of my X-rays, before and after root canal. Their clinic is really nice and open too. Karen at the front desk is super helpful with the billing process as well. Thank you Dr. Cohenca and team at Prime Endodontics! I'm feeling a lot better!

I was referred to Prime Endodontics by my dentist and I couldn't have been happier. No one wants a root canal, but Dr. Cohenca and team do a wonderful job at making it easier and pleasant. Top notch service and experience.

Dr Cohenca performed a root canal surgery on me. I had a very bad toothache and my dentist recommended Dr Cohenca as one of the best endodontists in the area to take care of the tooth. I went in dreading a painful experience and was pleasantly surprised at how easy and pain free Dr Cohenca made it for me. He did some tests and took some X rays, confirmed that I needed the root canal surgery and explained the entire process of what to expect before starting the procedure. The only mildly uncomfortable part of the surgery was the local anesthetic administration, which was expected. After that it was 45 minutes of procedure when I did not feel a thing! He even has a monitor where you can watch exactly what is being done on your tooth as the procedure happens. I was given a blanket and an IPad with noise reduction earphones and Spotify app on it so I could listen to some relaxing music during the procedure. Post operative instructions were given on a handout after surgery. My toothache was totally gone and I did not even need any painkillers post surgery during the healing process. Since he operated on me on a Friday, Dr Cohenca gave his card with cell phone number so I could contact him if needed during the weekend. He also checked on me the next day to see how I was doing. Overall I was super happy with my experience. I strongly recommend Dr Conhenca and his practice for any endodontic needs.

I had a great experience. From the 1st day I met the staff I felt very welcomed and everything was handled very professionally. I had been holding off having the surgery for a couple of years. I am glad I had Dr Nestor Cohenca do the surgery. Everything went smoothly and was over before I knew it. I have had very limited swelling and have felt great. I have not needed pain medication. Amazing experience. Thank you Dr. Cohenca.
