Dr. Tang explained everything in detail and the front desk lady was also very professional. There is not much pain during or after the root canal. read more

Dr. Tang is kind and soft-spoken. A root canal is no fun. However, Dr. Tang makes sure you are as comfortable as possible throughout the procedure. And, while it was uncomfortable, it was NOT painful. I truly appreciated Dr. Tang's thoughtfulness and genuine concern. read more

Beware of their undisclosed overcharges. I was referred by another dentist to Dr. Tang. He briefly spoke to me for 2 minutes and we agreed to not go through with the procedure. As I was exiting, the office admin did not talk to me about any costs and said I was good to go. A few weeks later, I receive a bill in the mail that my short encounter cost $171 out of pocket. I went to the office in person to pay the bill. I asked Dr. Tang and the office admin why I am being charged for a consultation when I did not receive an actual consultation. I reminded them I only talked to Dr. Tang for 2 minutes. They replied that "just speaking to Dr. Tang is the consultation." There are so many other great dentists in this area who provide affordable and helpful consultations that are most likely completely covered by your insurance. Don't get blindsided like me! read more

The girl in the front desk was not very friendly she was watching her dodger game on the computer. They couldn't help me. I was referred to this place cuz I needed a root canal. Need to look some where else. Get some nicer girls. read more

Thee best doctor who takes such care. He is not out to hurt you. Let him know when something hurts and he takes care of business. I recommend Dr. Tang to anyone in need of a root canal. Gentle professional and the staff is so kind and helpful . In the old days this seems to be the worst part of Dentistry. But if you have Dr. Tang it is a cloud in heaven. Thank you Dr. Tang thank you staff your the best! read more

I had an impacted tooth from a wisdom tooth that grew in sideways and I was told that I would need to get a root canal. My dentist referred me to Hong Kong Tang. I was dreading the root canal so I suffered through a week of pain before I gave in to make an appointment. It was a pleasant experience and so painless that I almost fell asleep. Doctor checked in with me to make sure I was doing okay. Thank you to the assistants and receptionist for the help as well. read more

I had initially went to a different office to have my root canal done and the service there was horrible; I felt uncomfortable getting my root canal done at the first location I went to. I took the CD of my CBCT scan I had paid for at the first location to Dr Tang and I am relieved to say that this office was the complete OPPOSITE of the first one. Here I DID feel WELCOMED, I didn't get attitude from anyone in the office and Dr Tang's aura was so warm and helpful and I definitely didn't feel like they were trying to charge me for something I didn't need. During the root canal procedure I had trouble breathing and I kind of freaked myself out with my claustrophobia but Dr Tang and his staff was so good at getting me through it. It's a 2 hour torture procedure that somehow they helped make it seem like a long lost bad dream. Dr Tang and his office staff smile and laugh with their patients...something that first office definitely lacked. I really hope I never have to have another root canal ever but if I do, I will definitely want Dr Tang to do it Thank you Dr Tang and staff! read more

I had a root canal procedure done yesterday by Dr. Tang and I cannot stress enough how pleasant my whole experience was. From the beginning when I called to make an appointment, I knew right then I had made the right decision. First off, his staff deserve a shout out. Everyone was so kind and it is honestly super rare for a receptionist at a medical office to be so kind. I was surprised at how informative she was and answered all of my questions without sounding annoyed (and I am sure I was annoying with so many questions haha). She made me feel welcome and I really appreciated it. I was originally only scheduled for a consult but when I decided I wanted to do a root canal right away, Dr. Tang went out of his way to do it for me, even when it was obvious there were other patients there. He was SO gentle during the procedure that I actually fell asleep quite a few times! That is freaking amazing. He made sure to calm my fears before starting and would ask me if I was okay during the whole procedure. This was the best experience I have ever had at a dental visit, no joke. Note: Care Credit is accepted. Thank you for everything, Dr. Tang and staff! I am forever grateful. read more

No phone call before a day in advance, in the day morning call back ask Dr Tsai questions, no response for over an hour. Asked in the store, the doctor said because other guests have already come, then what is the meaning of the appointment? same time booking more than two patients？It only takes a minute to return phone calls? she said don't have time. Probably just trying to make more money ，very disappointed ，btw，The reception was very poor and there was no Wi-Fi. read more

Hong-Ming Tang, DDS MS - Endodontists Near Me - Diamond Bar, California

If 5 star is the best, Dr. Tang deserves 10 stars! I was so terrified and stressed out about my root canal since day 1, then I met Dr. Tang! He is so gentle, super mellow, so pleasant. I didn't feel any pain during my procedure. Almost fell asleep listening to music while he worked on my tooth. He's very detailed, thorough and skilled . He took x ray during and afterward to make sure it's cleaned 100%. This is the most pleasant dental visit I've ever had, EVER! Highly recommended!! read more

See all

I highly recommend Dr. Tang for anyone who needs a root canal. I refer my friends and family to him and everyone has the best experience ever. I normally dislike dentist in general like everyone else, but Dr. Tang makes my root canal experiences positive. Yes, unfortunately I already had 3 with Dr. Tang. Each one of them went smoothly with no complication. So I am highly qualified to write a fair review, and yes, he is the one if you need root canal service. read more

Dr. Tang is okay. Problem is if they overcharge you, it takes forever for them to give you a refund.

I had root canals in both July 2021 and February 2022 with Dr. Tang, and had excellent experiences in Dr. Tang's office. Dr. Tang was very professional and gentle. He did excellent jobs. I recommend Dr. Tang to my family, friends, and any one who needs root canal. Recently, I received a refund check from Dr. Tang's office because my insurance paid more than expected. I respect this honest practice and am willing to testify here. Thank you very much, Dr. Tang! read more

I just had my 6 month follow-up for my apicoectomy and everything turned out fine. He is awesome! Dr. Tang and his staff were helpful throughout the procedure. They explained the steps as they were going through and made sure that I was feeling okay. I would definitely recommend him. read more

He is amazing. I went in to get a root canal done on a tooth that was pretty much hopeless. My dentist wasn't sure if it could be saved, but he had confidence that Dr. Tang might be able to do it. AND HE DID. It was a grueling procedure. Not for me, but for Dr. Tang. I actually, somehow, fell asleep on the chair. I think that says a lot about Dr. Tang if his patient can fall asleep during root canal procedure. He was as gentle as he could possibly be. Dr. Tang is a great doctor. He's also very kind and has a very soft speaking voice, which helps you calm down before the drilling begins. If anyone ever needs to get a root canal done, Dr. Tang is the best you can find in the area. read more

I have had two root canals done by Dr. Tang, one this year and one 12 years ago. He is extremely skillful and has a great bedside manner. His staff is second to none. They are very up front about costs and options. I have to drive about 45 minutes to see him, and do so without hesitation. His fees are very reasonable. This last time when I saw him, I had a little cough. He was very patient with me as I needed a couple of breaks. The staff gave me bottled water. It was a great experience. The office is very clean and modern. They have the very latest, state-of-the-art equipment. I highly recommend Dr. Tang. read more

I had to have a root canal done at the end of February of this year. My dentist , Dr. Tina Sun, told me that Dr. Tang is the one she wanted me to go to. Her entire office spoke so highly of him and I agree with them 1000%! I was So stressed from the pain of the cracked tooth I had, but he put me at ease. His partner, his wife, was fabulous as well. The procedure did not hurt at all. I had been told horror stories about getting a root canal done but honestly the experience was pleasant! He is so professional but very kind and a very calming spirit. I most definitely will go to Dr. Tang again if needed. His staff is wonderful!! Took care of all of my insurance needs and more. If I could give him 10 stars I would. Thank you, Dr Tang and staff! read more

Wow!! I've been a patient of Dr Tang's for over 10 years here in Diamond Bar, and all I can say is Wow!! His "chair" side manner is superb. His staff is friendly and knowledgable, and Dr. Tang's skill set is at the top of his game. I like the other Yelp reviewers actually "Fell Asleep" during a part of the procedure. I felt absolutely NO PAIN!!! I HATE PAIN..and I felt NONE....Thanks Dr. Tang for being a great doctor who really does care, and by providing such a state of the art facility to treat us so special.. Pretty cool "Doc"......pretty cool! Thanks again!!! read more

I am a terrible patient for any dentist let alone an endodontic specialist but Dr Tang is amazing! I broke a molar and needed a root canal. He explained everything he was doing and took great care of me! read more

If you need a RCT (root canal treatment) this is the office to go to. If you need a general dentist then see his wife Dr Tsai. These people are honest and ethical. I have worked in the industry for over 30 years. They are also great dentists! I would not go anywhere else. read more

Do not go to this dentist, we had an appointment last friday 3/20, they called and ask us to postpone because they cant reach our insurance company. So we postponed till tomorrow 3/27 3pm. The lady jessica called my wife this afternoon around 3:15 pm and ask us to either come in at 9 am or 12 pm. My wife called me so we agreed on 12pm. My wife called jessica back and said 12 pm is ok, however she said 12pm is not available now, she hang up on my wife after my wife told her that we can only do 12 pm or 3pm. My wife call her back and she doesn't answer her phone call. So I called and she kept telling me it is a rough time now and she need to accommodate people that have toothache. I try to explain to her that my wife been hurting all these days and took pain reliever, isn't she consider urgent too especially they already delayed the appointment for one week? In addition why would she try accommodate someone else without an appointment that are in the same urgent situation as my wife? She then hang me up a few weeks even after I called back. I even ask to speak to the dentist and she said she is the dentist, come on according to the name we know the dentist is a guy not a lady. Maybe she's the spouse however I do want to let her know that she shouldn't talk to her clients like this and hang them up even if you are the spouse of the dentist. read more

This dentist is truly amazing! I had gone to another dentist for a root canal for a period of 4 weeks. After 6 visits and tremendous pain I went to Dr. Tang. In one 2 hr appt he had my "complicated" tooth fixed. He and his staff were so kind and accommodating. They really care about your well being and are very professional. He has state of the art machines and knows the newest techniques. I will never go to another dentist for a root canal and I will refer everyone I know. read more
