Check out what some of our happy patients are saying about us:

Rebecca L. from Irvine, CA (Source: Yelp)


I had an accident which impacted 2 teeth about 20 years ago.  I tried to avoid the root canal procedure due to negative experiences shared by my family member and a friend. The discomfort and pain continued so I visited Dr. Yu who is a very knowledgeable and competent.  He conducted a thorough examination and identified the bacteria infection which warranted an immediate root canal procedure.  During the examination, he was very patient to answer all my questions and explained the details to ease my concerns and fear.  He conducted the root canal skillfully and I did not feel any pain or even discomfort during and after the procedure.  Although I am not familiar with certain terminologies regarding the infection, procedure, etc., Dr. Yu was able to communicate the details very well in Mandarin. Dr. Yu’s patience, professional care, and multi-language skills in English, Chinese, and Taiwanese and friendly staff are the reasons why I would highly recommend him to anyone who needs endodontics treatment!

Dr. Yu serves his patients in time of need. I needed an emergency root canal during COVID19 and he came through for me. I am forever grateful. He is everything that Yelp Review had said, “patient, skilled, gentle and friendly.” I would recommend Dr Yu at EndoCare Center to my family and friends.

Excellent! Very friendly, professional, and comfortable. Patients are very well cared for and the hardwork and dedication is very clearly shown. Such amazing customer service and a very clean, well lit and organized environment. A few years ago, I had some difficulties due to my root canal, and so I came here to get it checked up. To this day upon my recent visit to see Dr. Yu, it still remains perfectly healthy because of his help. That’s how confident I feel about his work and will gladly recommend this place to anyone.

I just had a root canal done by Dr John Yu. The whole experience was really pleasant. I liked how Dr Yu made sure that i was comfortable and well taken cared of throughout the entire process. The prices he charged me were very reasonable. The entire staff was friendly and attentive. I would most definitely come back again for any future dental needs and i can’t imagine how any customer could give him a bad review.

I had to have a repeat root canal because the bridge fell out and the root canal was infected again.  Fortunately, my dentist referred me to Dr. Yu.  I received first-class service from EndoCare Center.  Dr.Yu’s  office is modern and clean.  The staff is friendly and helpful.  Dr. Yu patiently explained my situation and answered all my questions before he performed the retreatments.  Dr. Yu made sure I was comfortable throughout the whole procedure.  Dr. Yu is very knowledgeable, gentle and skillful.  I would definitely recommend Dr. Yu and his office to those who have difficult teeth like myself.

I’ve been prolonging a root canal until couple days ago I had constant pain all night so I couldn’t wait any longer. I was hesitant because almost all yelp reviews are bad reviews for dentist. My dentist Dr. Kris Murakawa recommended me and I trust he whole fully so I scheduled an appointment with Dr. John Yu. He asked me some questions about pain I am in and got me in next day. Went over everything and best case and worst case scenarios. Pros and cons of everything and showed me exactly how much it would cost and I even paid before which is nice since you know there shouldn’t be any hidden charges. Went quick and painless and during the procedure he kept asking if i feel pain which I did not. All the staff was very friendly and place and equipment looked very new and clean. During these stressful times of COVID19 I would say you wouldn’t have to worry coming here. If anything bad happens I will update review but I doubt that. Thanks again for everything! Also I was hesitant of Sherry’s review but I looked she complains about everything mostly.

This was by far the best dental experience I’ve ever had. I know I am possibly one of the worst patients a dentist can have because of my extremely sensitive gag reflex, but Dr. Yu and his staff were very accommodating throughout the entire process. I had many complications with a cracked / chipped tooth and Dr. Yu was extremely patient and explained the entire procedure. I discovered I had an impacted tooth underneath the chipped tooth. My general dentist did a partial pulpotomy (essentially a half root canal) and I started to grow skeptical of my general dentist’s work since my brother started complaining of pain and he visited a specialist and was told that the general dentist’s work was outdated. So I kind of confirmed that with Dr. Yu. Its already been three months and I think the root canal was already starting to decay/rot/get infected. Dr. Yu told me that it was possible that the impacted tooth wasn’t even in the root canal and is simply resting against it but it wouldn’t be possible to know until a full root canal was attempted. I really hate getting things done but it was pretty painless this time around. My mouth was numbed with a series of shots. They put a rubber dam around my tooth/over my mouth to isolate it. It felt weird at first but I got used to it… turns out its an amazing invention. Having the rubber dam on meant no specks of amalgam flying into your mouth and making you gag… or disgusting bleach getting stuck at the back of your throat and then gagging and accidentally swallowing some (both things that have happened to me in the past). Also somehow even though they weren’t invasive at all with suction tubes, my mouth was completely dry. I’ve had problems with saliva build up with my general dentist even with their invasive suctioning. The whole procedure was painless and felt like it really flew by even though it really took about an hour. Dr. Yu explained what he did and what to expect afterwards. His staff even called to check up on me. This guy is great at what he does and I’ll be sure to refer him to my friends who might be in need of an endodontist.

Dr. John Yu did amazing job on root canal. Didn’t feel any pain at all except my jaw. Because I had to keep my mouth open all the way. Other than that, he did good job. I can tell he really enjoy fixing the tooth. Highly recommend him. If I need to get my tooth fix, I would not be afraid to go see him or try avoid going there. That’s how much I feel comfortable with him and his staff. Thumbs up to Dr. John Yu and his team!

Came here for root canal re-treatment, after having done my initial root canal procedure years ago at a different office. Before deciding on re-treatment, I had consultations for an apicoectomy and dental implant, but went with the re-treatment since there was possibility of saving the tooth. I recently had my 6 month follow up visit, and so far so good. Dr. Yu and the staff were professional. It was easy to make appointments through phone or text. And they’re timely in responding when I had follow up questions.

Betsy L. from Duarte, CA (Source: Yelp)


I was referred to Dr. Yu’s office by my new dentist. The ling term plan formy dental work started with a root canal and that’s why I’m here. First visit with Dr. Yu and I was extremely nervous. Not a fan of dentists. But after talking to him we decided a root canal was the right move and he fit me in that same day I was so well taken care of from the moment I walked in the door. Paperwork was ready and easy to take care of. Xrays were a piece of cake. Consult with Dr Yu was simple, thorough and he listened to all of my concerns. The dental assistant Iris was so kind and so understanding. Of course I left sore but lots of info, guidance, and every single one reminded me to call them any time with any questions. It was one of the best dental experiences I’ve ever had. Thank you to everyone at EndoCare Center in San Gabriel. I won’t hesitate even one second to recommend you!

Brandy M. from Sun Valley, Los Angeles, CA (Source: Google)


So glad I found Endocare !!! I was originally referred to another office for a root canal and explained I was in a lot of pain. They said the soonest they could see me was 2 weeks later. So I asked for another referral and was sent to Endocare. They were willing to take me in that same day(unfortunately I wasn’t able to make it), so they scheduled me for a consultation the very next day. I went in for consultation and was in a lot of pain. The Endodontist was very easy to talk and understood my concerns and wanted to help me especially because I was in a lot pain. I was able to come back that evening for a root canal. The staff is very nice and constantly checking to see how you are feeling and if you are feeling any pain etc … The next day they reached out to me asking how I was recovering, that was a first for me! I was soooooo happy at how they were able to accommodate me and the service they provided .. I truly appreciate it. THANK YOU ENDOCARE !!!!!

Jason K. from Rosemead, CA (Source: Yelp)


I’m one of the many patients that hate going to the dentist but going to see Dr. Yu really helps bring the anxiety down. I’ve come in for two root canals and a touch up already. I really like how he’s very detailed in his work and patient with you. He really takes the time to explain everything clearly. A lot of other dentists I’ve seen doesn’t even give me all my options and just goes to work. Not only Dr. Yu, but his entire staff has been really helpful and great as well. Thank you guys so much and keep up the good work!

Wen C. from San Diego, CA (Source: Yelp)


I was also referred to Dr. Yu’s office by referral, and I was amazed by the efficiency and fast availability in scheduling to help with my toothache. Dr. Yu for sure has very professional and extraordinary techniques for the treatment and the office staff are very friendly and patient. I also like how they keep on track of the patients after a few days after the treatment to just make sure the patients are doing ok. I am really grateful for receiving the quick and perfect quality of root canal treatment from Dr. Yu. Thank you again for the great techniques and fabulous service!

Montserrat G. from Walnut Valley, La Puente, CA (Source: Yelp)


This is the 2nd time I have had dental work at Endocare. The first time was for a root canal in 2017. The 2nd, was for an apicoectomy on another tooth just this week, January 6th, 2020. I was very nervous both times but Dr. Yu and his staff were so gentle, they put me at ease. Everyone at Endocare is very kind, pleasant and caring. They respond to all questions and concerns promptly esp. the aftercare questions that I have texted them about. I hope I have no further need to see an Endodontist but if ever I do, Dr. Yu will be my first choice. I have complete trust in him.

Wilson A. from Los Angeles, CA (Source: Yelp)


Dr John Yu is great Dentist, and their staff is great as well, the lady infront is kind and accommodating, and his dental assistants are awesome, they made my wife’s treatment no pain at all and they were very accommodating, a very kind and professional clinic, will definitely reccomend to family and friends.

Heidi F. from Pasadena, CA (Source: Yelp)


I was referred by my family dentist to see Dr. Yu for my toothache.  After consultation, Dr. Yu had to do a root canal on me.  He was very professional, very detailed oriented.  His staff was super friendly and explained to me all the steps so that I would have a heads up.  His did a fantastic job! Even though it was still scary, but the entire process was not painful I didn’t feel any pain at all.  Thank you Dr. Yu

Jingni Z. from Arcadia, CA (Source: Yelp)


Thanks a lot for Dr. Yu. I had been full of this treatment until the end of this treatment, and I realized that it was not uncomfortable at all.  Dr. Yu was very nice and gentle. I didn’t feel any anesthesia and didn’t feel any discomfort during the whole operation.  Awesome experience

Another endodontist had done my three molar root canals from two years ago and unfortunately was no longer answering his phone. I was having some pain underneath the crowns. My dentist referred me to Dr. John Yu. He skillfully identified that my bite was misaligned causing extra pressure to be exerted on the tooth roots and did an adjustment on the three crowns which were high. He also saw potential decay under the crowns on radiograph. I will follow up with my dentist on that. The pain has lessened from the procedure. If I need a root canal done, I would trust Dr. Yu to perform the surgery.

Kimmy W. from Rancho Palos Verdes, CA (Source: Yelp)


Dr. John Yu is the most professional and responsible endodontist I’ve ever met. Before I visited him, I had two other dentists to take the X-ray and checked on my #10 tooth. But neither of them can have such an acute insight as Dr.Yu. In addition, the way of his consultation made me worry-free and have total trust in him. During the procedure of root canal, I didn’t feel any pain or uneasiness at all. Dr. Yu definitely had superb technique for handling root canal in different conditions. I’m most impressed by his accuracy and efficiency. The office staff are also very patient and considerate. With no hesitation, I greatly recommend Dr. John Yu as the number one endodontist for your concern.

Claudia R. from Los Angeles, CA (Source: Yelp)


Endocare Center is the place to get a root canal, I came in to get a consultation with Dr. Au on my UL tooth because my dentist said i might need a root canal.  I had questions…  why i needed treatment, if i was not in pain. What i didn’t know was that i had infection on the tooth.  Dr. Au explain to me the cause and she also answer a few questions i had about my tooth.  Dr. Au was very nice and understandable.  I didn’t have to pay a lot of money like other endodontist that charge for consultation $115 and a separate fee for root canal.  I only paid for the root canal.  Dr. Au was very gentle when she was putting anesthesia and afterwards i didn’t feel a thing.  The staff was very nice as well.

The office is in the 2nd floor of the building. I like this office! They offer very polite and nice services, and highly professional treatment for root canal! They texted me beforehand, telling me what paperwork I need to prepare, and reminded me before the appointment. Dr Yu saved my tooth by fixing a bad root canal I did in the past. Although the remaining tooth is very small I don’t want to do implant. Thank you Dr Yu and all the staff in the office! I will definitely recommend this office to my friends, and am willing to endorse with my own experience anytime!

Dr. John Yu and his staff are so incredibly friendly and professional. I had a terrible tooth ache and needed a root canal fast, and they got me in to see him super fast. Dr. Yu was fantastic! He explained everything and put me at ease. He is a very skilled endodontist. I experienced very little pain during the procedure and little to no pain after. I was very happy! He was also readily available for questions after I left. I highly recommend him!

Sophia S. from Baldwin Park, CA (Source: Yelp)


About 2 years ago I had the worst pain and I went to two dentists. They both didn’t find anything and disregarded my pain. I finally went to my regular dentist and he referred me to Dr. Yu. Dr. Yu was able to get to the root (pun intended) of the problem! Even though root canals are not fun, this is probably one of the top experiences of going to a dentist. He explained the whole process and answered all my questions. Him and his staff were extremely nice and comforting through the whole thing. I would highly recommend going to him!!

Kaichou F. from Berkeley, CA (Source: Yelp)


I had a great experience here! I like that the procedure and charges were clearly explained in advance, and they paid attention to small details to ensure comfort, such as a thorough numbing procedure, a large dental bib, and a protective eye shield for the patient. Dr. Yu performed the procedure skillfully and preserved much of my original tooth structure, patiently answering questions about my x-rays. The assistant, Maria, was very thorough about checking my comfort levels throughout.

I’ve had root canals done on back molars bilaterally in consecutive years. Dr. Yu is young, modern, professional, very caring and compassionate to your pain. I paid cash at the time and it was still pretty affordable and he got me in really quickly…. and his staff are nice too. Old building but very new and high tech office.

Andrea C. from Los Angeles, CA (Source: Yelp)


I have had the worst experiences with dentists ever since I was a child. That being said, I have neglected caring for my teeth for quite a while and finally gathered the courage to find a good dentist and get on track with my oral hygiene. Needless to say, I needed a root canal and was referred to Dr. Yu. He made me feel very comfortable, he was not judgemental, just very direct and to the point. He made sure I was comfortable throughout the procedure. I do not have dental coverage, but the self pay price was very reasonable. I hope I don’t ever need a root canal again, but if I do I will definitely ask to be referred here

Victor C. from Azusa, CA (Source: Google)


I was referred to Dr Yu for a root canal procedure due to some insurance issues at my primary dental office. I dreaded the notion of going to someone else to perform major dental work on me, but let me just say that Dr Yu and his staff are just every bit professional and caring as the people at my primary dentist. During consultation, Dr Yu explained to me very clearly what the situation was with my tooth and the procedure. I thought I was only going in for a consultation and I would have to reschedule for the work but he said he was ready to begin right away. Root canals for me have always come with a little discomfort even at my primary office because I’ve been told I have long roots, as Dr Yu also mentioned. When drilling time came he made sure I was as comfortable as possible and asked me if I was ok every once in a while. In the end, I am very satisfied with my experience and if you need similar work done, please don’t hesitate calling Endocare center. I highly recommend.

Dr. Yu is a knowledgeable dentist who gives great care and attention to his patients. The staff is friendly, helpful, and attentive to everyone’s needs. I was referred to come here for specialized attention, Dr. Yu clearly explained the issues I was experiencing and provided the solution to my (weeks long) pain. I would definitely recommend anyone looking for a dentist to come here. Thanks to the staff for a very pleasant experience!

Irene F. from Alhambra, CA (Source: Yelp)


let me start with the fact that a had a general dentist that supposedly did root canals and crowns. so, i booked an appt and for 8 LONG HOURS with my mouth open 4 hours at a time….she dug and dug and dug into my gums! she could not find the third canal and booked me for another 4 hours!!!! i was sitting in the chair waiting for her and i freaked out…i just COULD NOT sit there for another 4 hours while she poked me with needles!!! i jumped out of chair and left. my brother referred me to John Yu DDS a specialist. of course it was expensive because he is a specialist in root canals…and i was already freaking out. this dentist looks like he just got out of med school…but he didn’t…just looks very young. anyway…everything went smooooothly….no pain, no excessive torture…he knew what he was doing and finished the root canals!!! thank god…a great experience. i want to say he has a fantastic assist name Iris. she is excellent at her job…very knowledgeable and reassuring! she was a great comfort to me. The office staff are all very nice also. anyone with root canal problems should come HERE!!!

John C. from Los Angeles, CA (Source: Yelp)


I was referred to Dr. Yu for a consultation for a root canal under a crown which had started to hurt and turned out to be infected. Dr. Yu and his staff were very professional and attentive, and took an x-ray to confirm the diagnosis and determined that I needed retreatment of the root canal. I set up an appointment, went in for the first visit, and went back to complete the procedure 2 weeks later. Everything went well, I had no pain or discomfort during the procedures (good application of local anesthetic), and they provided a sheet with clear post-procedure instructions. Everything went smoothly and without a hitch. A day later they called me to make sure I was doing alright (they put a temporary filling until I can go back to my regular dentist). It’s also a good thing that I got a text the day before each procedure asking me to confirm the appointments. I am very satisfied with the whole experience and would gladly recommend EndoCare Center.

Cheung S. from Los Angeles, CA (Source: Yelp)


Dr. Yu and his staff are wonderful! Dentist visits always scare me, especially I have heard people saying that root canal treatment would hurt a lot. First time I went in for consultation, Dr. Yu explained everything in details and answered all my question to make sure I understand the whole procedure. Second time I went in for the treatment, at first I was so nervous and scared, but the staff and Dr Yu were very patient with me and ensured me that it would fine and I wouldn’t feel anything after the anaesthesia injections. Unexpectedly, it really didn’t hurt at all! Mine was a tough case, so I had to go back in two weeks. Scheduling was easy and I love that they will send you text reminder a day before the appointment. And you can also change your appointment time by text which is very convenient!! Today, I went in to finish my treatment, again Dr Yu and his staff were super helpful and patient. They took the time to work on my teeth to make sure everything looks good. And even now after the anaesthesia wore off, my teeth doesn’t hurt or bother me at all! Thank you everyone in the office for making this whole process stress free! 🙂 Would definitely recommend Dr Yu to friends!

I was referred here by my general dentist and it was confirmed that I needed a root canal. Dr. Yu was great in explaining the process and the receptionists were lovely and so hospitable! They helped me move my appointment earlier because I couldn’t tolerate the pain. The procedure was not fun but Dr. Yu and his assistant made sure I was comfortable throughout the procedure.  Overall a great experience!

Liane H. from El Monte, CA (Source: Yelp)


My fiance was referred here by his dentist for a root canal. He was in a lot of pain but Dr. Yu and his staff made him feel really comfortable and he was able to do the consultation and treatment the same day. The staff was very friendly and even gave us a number to text if my fiance had any problems afterwards. Once the root canal was done, the pain was alleviated and he was finally able to get a good night sleep
