Dr. Jason Cho is an exceptional endodontist and a true professional. Another endodontic office told me that my tooth could not be treated and would need to be extracted. Thankfully, I decided to get a second opinion from Dr. Cho. I am incredibly grateful because he was able to save my tooth. Instead of recommending extraction, he carefully evaluated my case and found a solution. Dr. Cho is knowledgeable, attentive, and genuinely cares about his patients. He explained everything clearly, answered all of my questions, and made me feel comfortable throughout the entire process. The treatment went very smoothly. I had no pain after the procedure, no inflammation, and no complications. Everything healed perfectly, and the entire experience was much easier than I expected. The office is modern, clean, and welcoming. The staff is friendly, professional, and made me feel comfortable from the moment I walked in. I highly recommend Dr. Cho to anyone who needs an endodontist. I will definitely be recommending him to all of my friends and family. Thank you, Dr. Cho, for saving my tooth! read more

Let me tell you with certainty , you will be in reliable hands with Dr. Cho, I was so relaxed. Thanks again to the team, I can't Thank you enough! Tina Buckley read more

Came in for a root canal and had the best experience ever. Dr Cho is very calm and super knowledgeable. He is also one of the friendliest people I have ever met. He explained every step of the process to ease anxiety and put numbing cream before the numbing injection so nothing hurt at all in my whole process. I don't want to get another cavity, but I know if I do I wont have to worry. I also dont have pain after currently. His front office staff and back staff were very welcoming. read more

I had to have a root canal during the holidays . While I had much trepidation regarding the procedure, there was necessity to take care of it as soon as possible. Dr Cho was recommended to me by my general dentist. I would highly recommend him to anyone in need of a endodontist. No matter where you live it's worth the drive to Irvine. He quickly sensed my apprehension. He had his wonderful RDA Emily put my mind at ease. They explained each and every detail as the process went along. From start to finish I knew what was happening. I'm so grateful to Ruby who kept me on her short call list for this opening. She went above and beyond to accommodate me. Mike who works in the front office stayed to help me checkout. This all took place several days before Christmas. I want to thank each and everyone who helped me enjoy my holiday. read more

Jason Cho, DDS - Modern Endodontics and Microsurgery - inside the waiting area ! - Endodontists Near Me - Irvine, California

Very impressed with the office and Dr Cho. They were very attentive to my needs and the procedure went better than expected.

I had a root canal and internal bleaching done by Dr. Cho, and I can confidently say he is one of the best endodontists I've ever encountered. As a dentist myself who has worked with many specialists, I don't say that lightly. Dr. Cho is incredibly skilled, calm, and gentle--with a soothing voice that instantly puts you at ease. His communication is clear and reassuring, and he truly makes you feel like you're in good hands. The office is top-notch, equipped with the latest technology, and his team are just as wonderful. They're attentive, professional, and genuinely care about patient comfort. I felt completely at ease throughout the entire process and wouldn't hesitate for a second to refer my own patients, friends, or family to Dr. Cho for any endodontic care. Thank you, Dr. Cho, for taking such great care of me. You're amazing at what you do. read more

In the distant past, my wife and I experienced difficult root canal procedures. This time, my dentist recommended Modern Endodontics. The name is appropriate because they have modern technologies that some endodontists might not have. Dr. Jimmy Pham was able to see what he was doing using a viewer containing what appeared to be microscopic lenses. I chose to pay extra for the GentleWave laser system for disinfecting the roots. He used a CT scan to guide his work. Do not assume that all endodontists have the latest technologies. The new ways of doing root canals are much less painful than the old ways. read more

I would highly recommend Dr. Pham if you need a root canal. This one was quite involved and required some additional dentistry prior for the procedure. He took care of the issue and completed the root canal. He and his staff do all they can to make the experience positive. read more

Very grateful to Dr. Pham and the team! I started experiencing aching tooth pain recently, and went to my dentist. He couldn't see anything on x-ray, and recommended that I visit an endodontist. But the endodonist he recommended had a lot of issues. E.g. that endodontist's office couldn't figure out my admittedly confusing insurance, and I noticed that the endontist had a tendency of going online and fighting with reviewers who'd left bad reviews - never a good sign. So. I hopped onto Yelp, and found Dr. Cho's office. His team was amazing. They squeezed me in to see Dr. Pham the following day, and worked late to figure out my insurance. (Seriously! I got an email from them at 6:00 PM!) Dr. Pham was incredibly thorough in testing my sore tooth, and very kind when he delivered the bad news: he recommended that I get a root canal. But he assured me he could get me in the following Thursday. On the day of, the office manager remembered that I had mentioned a neck injury, and got me situated in the room. The process was incredibly quick - I was in and out in an hour and a half, and left with no pain. Even after localized numbing agent wore off, I barely felt any pain. The day after, there was confusion with my dentist around my insurance, and the office manager at Dr. Cho's office went above and beyond to talk to my dentist's office on what they were billing, against my maximum allowance. They also explained my insurance to *me*, which was greatly appreciated! Thanks all - so appreciate you! read more

If you're worried about root canals (as I have been... a lot), I hope my experience puts you at ease. Today, Jul 2023, was my second root canal with Dr. Cho, and again, just like the 1st one a few years back, it was beyond expectations. Just like the first one, I was so surprised that my root canal can be so painless and smooth. His experience and expertise in my view is the best in Southern California, combine that with cutting edge modern technology that his office has invested in, and his IMPECCABLE bedside manner putting the patient at ease, makes my experience 5+ stars. My first root canal with Dr. Cho was years ago and I had a crown done by my dentist Dr. Yu, and together the tooth has had zero issues on pain, discomfort or functionality over the years. Dr. Cho is so genuine in ensuring patient comfort, checking in with you throughout the root canal, taking measures to ensure there is minimal discomfort, and ultimately and most importantly doing a fantastic job with the root canal itself. I would also be remiss to not mention my experience with Ruby, like attracts like and seeks the company of its kind, she too like Dr. Cho was so genuine, sincerely caring, thorough in explanation, and putting one at ease. During the initial consult, I walked away with extreme gratitude for Ruby. She's awesome. Also grateful for Jennifer today, she helped the anesthesia process go very smoothly. Thank you. There are two dental professionals in Orange County who I personally trust to do an exceptional job, true masters of their crafts, have impeccable bedside manners, and who are genuine, honest and SINCERELY caring about their patients, one is my general dentist Dr. Sean Yu in Orange County, the other is my endodontist, Dr. Cho. The quality of their work is absolutely exceptional. For anyone who doesn't like the sound of drills (I don't), I brought headphones / AirPods and listened to an Audible book. Today when he said the root canal was finished, I asked him twice if it was really over that fast, it felt like getting a cavity filled, completely painless and over fairly quickly in my mind. I was also appreciative that Dr. Cho numbed both sides of the tooth, instead of just one side. I asked for a little extra numbing gel beforehand, so that was super smooth. As someone who has drank lots of black tea and too many sweets that are not ideal for oral health, I'm grateful for folks like Dr. Cho and also his graciousness in answering all my questions so that I can build new habits that are more ideal for oral health. read more

Who will be not scared of going to a dental office, especially when you're facing a root canal, right? Well.. Dr. Jason Cho is the one you won't be. Part of my crown on #2 molar fell off during the pandemic and I just procrastinated visiting the dental office until it developed excruciating pain all of a sudden on last Thursday evening. I was referred to Dr. Jason Cho by my general dentist, Sean Yu, but I was very scared of carrying this pain over the weekend if Dr. Cho wasn't able to schedule me in sometime on Friday. I was panicking.. But Dr. Cho and his office ladies worked hard to squeeze me in and took care of my dental needs even thou their schedules were packed on that day. I visited the office 1145 and got out around 1:30. Dr. Cho didn't say anything but I think he skipped the lunch because of me.. The most wonderful part is his outstanding skills and treatment procedures. During two hours of treatment, I felt so comfortable enough to fell asleep.. twice... i am not joking.. lol Thanks to Dr. Cho and his staff, I'm completely out of pain this morning and feels like nothing happened. Pls look no further.. Dr. Cho is simply the best endodontist in town, ever!! Thank you again!! read more

Dr Cho has taken care of me, and several of my family members in the last couple of years. His bedside manners are fantastic, he is extremely skilled, and his staff is very accommodating. I've referred all of my friends to him for endodontics services, and he's the only one I would use in the area for any endodontic needs. We're fortunate to have his expertise here! read more

Overall really great experience. Dr. Cho is friendly and very professional. He made me feel confident in his recommendations and overall procedure. He took the time to explain my situation, which made me feel comfortable. Great staff as well. Ruby at the front desk is very accommodating and friendly. Highly recommend! read more

No one likes to have a root canal--yikes. But so grateful I was referred to this awesome Endodontics office. Dr. Cho and his professional staff are truly awesome. The office is beautiful and clean and they make you feel very comfortable and confident of their specialty. Thanks also to Dr. Cho's dental assistant, Mike and wonderful front office personnel. I highly recommend Modern Endodontics and Microsurgery. read more

I really do not appreciate the way the lady at the front desk named Heidi treated me today after going through a stressful procedure. She acts as if you don't matter and are less than her. Giving two stars because the rest of the staff were great. read more

Hands down the best! From scheduling to consultation to the actual day of procedure, Dr. Cho and his staff were very professional, easy going, and caring. ! I hate needles, but he was very gentle and also walks you through every step. I did not feel a thing! Watch all those videos on YouTube to get yourself knowledgeable or prepared about whatever the procedure your getting, be scared, if you get it done here it wouldn't even matter because they do such a great job! The office is modern, really clean, and updated! They also let you borrow their earphones if you forget yours:) I would definitely come back here if I need anything again! Thank youuuuu!!! read more

It was the day after New Years, everything was closed, and I was in excruciating pain. Dr. Cho was booked solid, but he somehow fit me in and took care of me. I highly recommend Dr. Cho! read more

I wish I could leave more than 5 stars for Dr Cho. I was referred to him, after seeing a new dentist as my former dentist retired. My new dentist was concerned about a tooth that had formerly had a root canal, but looked a bit off. Dr Cho was so kind and gracious, took a quick CT Scan and told me the tooth is fine, nothing needed from a dental perspective. However, he did tell me that he could see my sinus was inflamed and to see my ENT, which I did. My sinuses are greatly inflamed and infected, and I will be having a procedure in a week to have them drained. I would not have realized this, without his direction. So although he didn't do any procedures on me, his honesty and concern for something else, is greatly appreciated. If and when I need any root canal work, he will be my guy. read more

I am updating my review to 3 stars to be fair to the billing department. There was no explanation as to why it took them so long to call me back HOWEVER they admitted to billing me wrongfully and took care of the problem only after I posted a yelp review. I will update my review again if I ever let this dentist do any work on my teeth. read more

I had a root canal done by Dr Jason Cho a few weeks ago whom I was referred to by Dr Sean Yu of Irvine who afterwards has completed the crown work on the tooth. Everything went well and I feel very pleased with the result. Both these doctors did their best to save this tooth and they succeeded. Dr Cho called me on the phone a few days after treatment checking up the condition which was much appreciated. I really felt I was well cared for. The office staff and nurse seemed also well organized and very courteous. Dr Cho works with Dr Sean Yu very closely as a team which was very helpful. So, in conclusion I have a high recommendation for Dr Cho with no reservation! read more

Dr. Cho is a skill professional who takes pride in what he does. His staff are efficient, helpful and friendly. I have never had such a positive experience EVER with any dental office. Dr. Cho is gentle and reassuring and I am so appreciative for his help in a complex and somewhat negative dental situation. read more

I am very lucky to have Dr Cho do my root canal. I have chronic pulpitis for almost 5 years. He is super professional and gentle. His office is very modern and clean. When I talk to him about my symptoms and experience, he was listening to me carefully and patiently. He is very creative and helpful to discuss with me about the solution, plan, and the risk. His hands is very skillful and gentle. I do not even have any painful feeling when he numb my gum and conducting the surgery. 2 hours root canal was like doing a spa. Front desk Michelle is very nice to help me reschedule so I can get it done earlier. His assistant Mike is very nice and considerate. Thank you so much Dr Cho and your entire team for saving my tooth. read more

Dr. Cho was recommended by my general dentist, Dr. Yu. I was experiencing a shooting pain in my gum (nerve?). They were so kind and accommodating since I couldn't come in during normal business hours. Dr. Cho agreed to stay a little later and saw me at 5:30pm. Dr. Cho was very friendly and personable. He was extremely gentle when he used the instruments to perform tests to assess my pain. He thoroughly explained and walked me through each test he was doing. Dr. Cho and his assistant, Mike, worked very well together. The chemistry between the two made a world of a difference and helped me relax a little. Mike made me feel very comfortable and was very gentle when he took my x rays. He checked in with me here and there to make sure I was still doing fine throughout the whole exam. Turns out that I didn't need a root canal! Dr. Cho said the pain I was feeling was due to a sinus infection and that it would go away on its own. You can tell he genuinely cares for his patients and is an honest guy. I would highly recommend Dr. Cho if you need a root canal. read more

I'm writing this review for Dr. Cho on behalf of my mother who received treatment from him three days ago. She stated that Dr. Cho's skill as an Endodontist is impeccable. She felt no discomfort at all from numbing injection to procedure and after the procedure. She did not take any pain medication post op and stated she felt no discomfort. She is in her 70's and has undergone a wide range of dental procedures over the years including extractions, crowns, bridges, caps, implants and previous root canals. My mother said that she has never met a better dentist and feels sorry for dental patients who have no idea what an outstanding dentist and excellent care really can be and settle for less. Recommended highly. read more

EXCELLENT experience. Friendly, thorough, caring and knowledgeable. Every aspect of my experience with Dr Cho's office was top notch. Was kept very comfortable during the procedure itself and there was lots of communication about what to anticipate before, during, and after. Absolutely recommend. read more

I was very nervous going into my root canal procedure but Dr Cho and his staff did an amazing job from start to finish. I just had a cleaning done a few days before and that was actually more painful than the root canal. I didnt feel anything the whole time and the recovery itself was great! Now when i hear people talk about how horrible their root canal was i have no idea what heavy handed butcher they went to go see. Dr Cho's office was nice and clean and i will recommend them to anyone. read more

Dr. Cho is an incredible endodontist. I am so glad I was referred to Dr. Cho just in time. Dr. Cho is extremely talented, detail oriented and compassionate professional who goes over and beyond in making sure the individual gets the right treatment. I saw Dr. Cho recently for a root canal procedure and he demonstrated superior problem solving skills and took the time to walk me through the x-rays, process and pre/post treatment care options. Dr. Cho is supported by a well qualified, trained and soft spoken staff in his clean Irvine facility which adds to an overall positive experience. I highly recommend Dr. Cho for any endodontic treatment. Thank you! Dr. Cho and team. read more

Dr. Jason Cho was probably the best dentist I've ever been to... His office is clean and beautifully designed, his staff are friendly and professional. I'm a bit of a baby when it comes to the dentist and I needed a root canal and was quite nervous but he instantly put me at ease and perform the procedure without complication asking me all the time how I was doing, explaining the procedure in detail etc.... I would highly recommend Dr. Jason Cho for your dental work... Julia B. read more

Dr Cho + his staff for the win! Start of Labor Day weekend tooth goes from bad to worse and they can get me in Friday late afternoon! Now, I have had previous root canals with Dr. Cho so I knew it was going to go well. He takes care of things quickly- he got me out of pain ASAP and the actual root canal was painless! A clean, precise and thorough environment - you can just tell he truly cares about his patients! One of my best finds! Highly recommend! Thanks again Dr. Cho! read more

Update: I had another visit to Dr. Cho because I still felt sensitivity on my affected tooth and it also radiated to the adjacent tooth (this was two weeks after I had my procedure). Since I was scheduled to have my crown the next week, I wanted to make sure everything was fine prior to putting in the crown. So, I called the office and left a message to Michelle at the front desk. Dr. Cho then personally called me after business hour and scheduled me to come for another checkup right away to make sure there was no infection. I went in on Friday and he checked everything for me. He said that he didn't see anything wrong with the tooth and the sensitivity was normal because the body was still healing. Again, he was gentle and patient with my concern and ensured me that he will check again if I still feel pain after putting in the crown. I thought I was going to get charged for another checkup but he didn't charge me anything, which I truly appreciate! I had my permanent crown put in a few days ago and I have not had any issues with my teeth since then. Dr. Cho, thank you again for your excellent work and team! Truly appreciate everything you do! Also, not to mention that his office is really nice, clean, and modern! read more

I came to see Dr. Jason Cho after having a root canal that did not cure a sensitive tooth. He appeared to me as a thoughtful, humble, and kind person. I took his suggestion and let him perform a second root canal in the same tooth in which he discovered a root canal that was missed by my regular dentist. The sensitive problem has never gone away, so I came back to see him a few more times. At our last meeting, after perused the 3D Xray for sign of infection, he tested my bite and suggested that I check with my dentist for an overbite at the side of that tooth. He explained that the traumatized gum was never properly healed caused by the overbite at that tooth. I believed he was correct because of a new bridge that I had a few years before and how I felt ever since. I has already asked my dentist correct my bite and have been feeling better. Throughout his treatments and many diagnoses, he gave sensible advices, demonstrated his high professional competence in search for the right treatment, and was never afraid of being transparent. He's quite a gentleman who cares deeply for the well-being of his patients. I feel so fortunate for being one of his patients. read more

This was a great experience all around in a super clean h environment- Dr Cho and staff did an amazing job helping me out in crisis basically when you have tooth pain nothing else matters and the team really made it easy to understand the process get a pain free result and get back to living even during this pandemic which I'm incredibly thankful for ... thank you for the help your team and office are amazing - HIGHLY RECOMMENDED !!! read more

I saw Dr. Cho for 2 root canals. He was the most gentle dentist I have ever come across! It is a totally modern and up to date office with all the latest technology. The staff is amazing as well and totally puts you at ease. Even after the numbness wore off, I still didn't have pain. I did take a naproxen a few hours before the appointment and Michelle at the front desk offers another afterwards. I would highly recommend this office! read more

I had reconstructed root canal and I give this Dr a 5 star. Dr cares about my teeth health and professional

Went in for my first root canal. I was very nervous and in a lot of pain. I called to get more information and I got an appointment right away. Dr. Cho was very quick and professional explaining the process. I highly recommend him! read more

I cannot say enough about Dr Cho. I had 2 root canals done by a dentist and she messed up both of them. Both had infections but one had to be redone. In the past, whenever I go to the dentist either for a filling or a root canal, it would be painful each time. The worst part is when the needle is inserted into my mouth, I can feel the screeching pain. So when I had to redo the infected root canal, I was very fearful. However, when the day came and the procedure started, I was shocked to not feel any pain. I only felt some pressures. Dr Cho explained every step and was so gentle and patient! I cannot say enough about him. Then after the fact, I expected to be sore and in pain from the recovery. I did not feel a thing after. Thank you Dr. Cho. You are a miracle doctor and I will never go anywhere else if I ever need another redo. If you are reading this, read no more. I guarantee Jason Cho is the best in his class! I've referred him to all my friends and family read more

Went in for my first root canal dreading a painful experience, instead I found myself in a super clean and modern office with staff that were all super pleasant and patient answering all my questions. Dr Cho was also very patient and explained clearly what was going to do and what to expect afterwards. I'm very glad Dr Cho and his team were able to make my first root canal experience no worse than getting a filling fixed. Thanks Dr Cho and Mike. read more

I had a root canal with him when he was in Irvine Endodontist and he was the best specialist I ever had. I sent my boy when he had an accident. The doctor is gentle and nice. I am sending my husband! read more

I can't thank Dr. Cho and his staff enough for the wonderful treatment I received in their office. Dr. Cho came highly recommended by my dentist and his staff after a large filling replacement resulted in an irritated nerve and, finally, a root canal. Having never had a root canal and having heard unsettling stories about them, I was dreading the procedure. Looking back, I'm now amazed by how simple---and painless---it was. Dr. Cho is gentle, thorough, and patient. The office has a relaxing energy. The entire staff is kind and reassuring; I felt cared for, listened to, and valued. When I went back to my regular dentist this week for a crown on the tooth that received the root canal, he commented on how well the root canal had turned out and how great the tooth looks. I'm grateful to Dr. Cho and his expertise for saving my tooth. (This review was written by Erik's wife.) read more
