I chipped my tooth a few weeks back and Dr Tang was the only one who could fit me in last minute to evaluate it. I ended up getting a crown on the tooth and the whole experience was awesome. Dr Tang and his staff made me very comfortable and explained everything in great detail. I’ve never had a more pleasurable dentist visit in my life! Highly recommend.

This is what every dentist should aspire to! We have been patients for a number of years. Dr. Tang has a very friendly demeanor and a wonderful ‘bedside’ manner. He is extremely patient and takes the time to explain his findings, treatment options and is never pushy. His staff is so wonderful! They are easy to talk to, work with you to get the appointment that best suits your needs and are ALL very efficient. The best customer service!!! From the dentist to the hygienists as well as the front desk staff, my family and I cannot say enough great things about them. We highly recommend them all!

It took me years to find Dr. Tang. I’ve gone through so many dentist because either I didn’t trust them or I didn’t feel that they valued me as a client (making me wait a really long time). 2 separate friends recommended Dr. Tang to me so I thought I need to give him a try and I’m so glad I did. He’s great. His entire office is friendly and welcoming. I also trust him, which is really important to me. I’d recommend him to anyone.

Great reception and customer service. Very professional and efficient. The dentist Dr. Tang is very knowledgeable polite and kind and very professional. The staff is human, real people.

Great dentist and staff! We were not happy with our former pediatric dentist and finally switched to Dr Tang after hearing good things. So glad that we did. Now, Dr. Tang has been our family dentist for several years!!

Dr. Tang is a meticulous and thorough dentist. I recently went to his office as businesses are starting to reopen and was impressed with the level of care and precautions taken by himself and his staff (…). My family routinely goes to Dr. Tang’s office for all our dental needs, we have never been disappointed.

Briana R from San Francisco, CA (Source: Yelp)


I’m a new patient and just had my first appointment today, and it was just such a great experience. From beginning to end I felt very welcomed and comfortable. I’m used to my mom making all my appointments and her being there with me so I was a bit nervous “adulting” for the first time on my own. The women at the front desk were incredibly nice and answered every question I had. Dr Keith S. Tang helped me understand my teeth better and what I should be looking out for.

Jason L. from Costa Mesa, CA (Source: Yelp)


Dr. Tang is a wonderful dentist. I’ve been his patient for 10 years, and he has performed an array of procedures for me including routine cleanings, fillings and extractions. We’ve also discussed orthodontia, mouth guards, and teeth whitening. He is very personable, incredibly knowledgeable, and takes the time to thoroughly explain the problem and all options available. Best of all, he’s trustworthy, understands his limits with more complicated issues and doesn’t hesitate to refer you out to a specialist for another opinion if necessary. The quality of my dental health is much better since I’ve been a patient of Dr. Tang.

Carol B. from Lake Havasu City, AZ (Source: Yelp)


I have been going to Dr. Tang for about six years now. I’m very pleased with my experiences there. Very minimal waiting time in the lobby. Very professional. As he is doing a procedure he’s very careful to explain everything that he is doing, as well as checking in to make sure I’m doing okay every few minutes. Very pleasant receptionist and dental hygienists. Thank you Dr. Tang!

Ellen K. from Irvine, CA (Source: Yelp)


Dr. Tang was very thorough in his assessment of my 7-year-old daughter’s dental needs and very sensitive in his approach while using language my daughter understands. State of the art equipment and friendly staff. What a world of difference compared to our previous dentist. I wish I found him sooner.

Cynthia F. from Newport Beach, CA (Source: Yelp)


Dr. Tang and his staff are courteous, professional, and their customer service is excellent.  The practice has all of the newest digital technology for imaging your teeth and each treatment room has a flat-screen TV, which is a nice diversion if you’re getting a lengthy treatment.  I am a cash patient, so I have no comment to make on insurance billing, but the prices are lower than what I was paying at my last Dentist in Newport Beach.  I highly recommend Dr Tang.

Stephanie W. from Anaheim, CA (Source: Yelp)


My boss recently found Dr. Tang and had many nice things to say about him, so since I was looking to change dentists, I thought I would go ahead and see for myself just how fantastic Dr. Tang is. He was indeed very thorough and explained everything to me (even showing me pictures of my teeth). The front office staff, as well as his assistant, were also friendly and attentive. I am hopeful that Dr. Tang will prove to be a long-term dentist for me. Thanks so much for the cleaning…and I will be flossing two times a day from now on!

Young C. from Irvine, CA (Source: Yelp)


The family has been seeing Dr. Tang for over seven years now, and I can’t say enough positive things about him and his operation. Clean facilities, great staff, caring Dr., and wonderful service! I’ve been seen for everything, from a routine check-up to emergency broken cusp on the weekend. Each time, I know I’ve gotten the best care available.

Erica S. from Long Beach, CA (Source: Yelp)


Dr. Tang and his staff are just the best. I have such a crazy schedule, and I often postpone my dentist appointments because they are expensive and time-consuming. The staff always accommodates me, and Tony and Jasmine always help me out in whatever way they can. They are so kind and helpful. And  Dr. Tang is a really amazing dentist. I would recommend coming here if you are anywhere nearby!

Lori M. from CA (Source: Yelp)


Dr Tang and his staff are amazing! They always make sure you are comfortable and know exactly what to expect from your treatment or service. I went to a specialist he referred me to and he even took the time to call me and make sure everything was going well while under that doctor’s care. I was so impressed. He also is constantly learning and adding new services and technology to his practice and I love how he stays on the cutting edge of the industry to bring the best service to his patients.

Susan L. from Fullerton, CA (Source: Yelp)


Very nice, state of the art office.  Lots of operatories, easy instant x-ray developer, fancy tv screen that actually goes right above you while the dentist does his work but most importantly, Dr.Tang does the least invasive but necessary procedures.  I went to him for a second opinion regarding a crown and after doing several simple tests he adjusted the bite on my molars to take care of my molar sensitivities.  Making him my dentist!

(…) I have had some extensive work done and have been very pleased with the results. He and his staff are always very friendly, professional and most of all caring. They all communicate very well and are great with follow through and follow up. I especially like the new texting method of reminding me about my appointments. Regardless of my insurance benefits, Dr. Tang has me as a patient for the rest of my life! If you are looking for a dentist who is caring, compassionate, professional, and honest Dr. Tang is THE guy!

Ellen Gross (Source: Google)


Dr. Tang and his staff are amazing. Best dental office I’ve ever been to. Dr. Tang has very high standards and all of his associates are skilled, kind, and friendly. I’ve had several different dental insurance plans over the years and they’ve been able to work with all of them.

Adrianna G. from Moreno Valley, CA (Source: Yelp)


Dr Tang and his staff are just absolutely amazing. They are really good at taking their time and making sure you get the right care you need. I am extremely scared of dentists but not once did I feel uncomfortable there. It is super hard to find a good dental office so I’m super stoked I came across them. It was my first visit and I already felt so comfortable and welcomed by the staff. I’ll definitely be going back and recommending everyone to go there for services.

Craig U. from Laguna Hills, CA (Source: Yelp)


Keith employs the latest techniques and tools in the industry.  If you want to see someone who is always concerned about his patients well being, I would highly recommend him.

Dr. Tang has been our family’s dentist for over 11 years. My children have been going to him since they were 2 years old and they never mind going to the dentist because his office is very family-friendly. My wife has had a lot of major dental work done over the years, having had bridges and crowns replaced and she feels very secure with Dr. Tang and his office staff because of the high level of care. Dr. Tang is always using the latest equipment and technology, and his office staff is proactive with the paperwork and communicating the dental insurance coverage and explaining all of the financial aspects of care. Dr. Tang and his staff are professional, trust-worthy, caring and we would never go anywhere else for our family’s dental care.

I’ve been a patient of Dr. Tang’s for over 7 years now and am very happy with the care he and his team have provided to me and my teeth. I recommend Dr. Tang and his outstanding staff. I highly recommend Dr. Tang and his staff to anyone with any kind of dental phobia – as much as I dislike visiting “the dentist” I love visiting Dr. Tang’s office.

Kathy Pham (Source: Google)


I’ve been going to Dr. Tang for almost 9 years and have referred many of my friends & coworkers to him because that’s how much I like him and his staff. Dr. Tang is a caring dentist and his staff is a great reflection of him. They’re professionals who want to do a great job for the patience. I highly recommend Dr. Tang.

Pamela Bryan (Source: Google)


My dentist retired after going to him most of my life and I was at a loss to find another Dr I felt comfortable with. I took a chance and scheduled an appointment with Dr. Tang. I was worried because I’m very particular. I felt at ease when I met Dr. Tang and he explained everything and answered my more than 20 questions). I’ve been going to Dr. Tang for years now and I’m happy he’s young and not retiring anytime soon!!!!

Tiffany Y. from Irvine, CA (Source: Yelp)


After I found dark spots on my teeth, I panicked and could not wait 3 weeks until my next scheduled cleaning with my previous dentist. That other dental office was unable to reschedule me for a better time, which led me to Dr. Tang, and it ended up being one of the best dental visits I’ve ever had.

Marku U from Laguna Beach, CA (Source: Yelp)


I have been going to Dr. Tang for several years now.  Great Dentist.  Great Support staff as well.  Very accommodating in times of need to get you fixed up ASAP, like if you lose a filling or have any sudden issue with a tooth.  Dr. Tang takes pride in his work and his commitment really shows.  He also has some very good contacts/referrals in the event you need Oral Surgery as well.   I have recommended Dr. Tang any time I hear someone talking about needing a Dentist in the Orange County Area.

Charley H. from San Jose, CA (Source: Yelp)


This is hands down the best dentist I have ever been to. Dr. Tang is the most thorough and professional dentist I know. The work he has done on my mouth is sure to outlast any previous dentists. Normally when I have gotten a filling or a crown, I could always feel it and tell that work had been done to that tooth. With Dr. Tang, it’s totally seamless and feels amazing. I will be coming here for many years to come. He is a textbook dentist and if things weren’t done right with other dentists, he will work tirelessly to make it perfect.

Sean M. from Irvine, CA (Source: Yelp)


I’ve been to many dental offices over my lifetime but this is the most professional, most caring of all!  Dr. Tang personally does the cleaning with meticulous care and attention to every tooth,  measuring for recession and mobility as he cleans. His office is well-managed,  appointment times are honored and his staff is caring and efficient. He does not try to sell procedures you do not need but instead takes a personal interest in your dental hygiene,  recommending ways to keep your teeth and gums healthy.  I feel fortunate to have found such a great dental office in my area.

Garry Z. from Signal Hill, CA (Source: Yelp)


My experience with Dr Tang and his staff has been outstanding.   His staff of receptionists and dental assistants have always been extremely professional.  As a dentist, Dr Tang is extremely knowledgeable.  What I appreciate is that I have never felt like I was being up-sold or pressured to do anything other than what was needed.  During cleanings, he does a very thorough examination and monitors any changes from your prior visits.  I am very happy with Dr. Tang and his staff and recommend him highly!

Pamela S. from Irvine, CA (Source: Yelp)


Dr. Tang is the best dentist in Irvine. After my long time dentist retired, I didn’t know who to go to. After checking out many dentists and going to several for cleaning appointments I found Dr. Tang to be the best. Dr. Tang really cares and will always treat you well. I have referred friends who have been very happy with Dr. Tang. Thank you Dr. Tang for taking such good care of me.

Maricela M. from Cerritos, CA (Source: Yelp)


Second time at Dr. Tang’s office. By far the best dental office I’ve been too. The front staff is very friendly, kind, helpful the best. Back staff/Dr. Tang’s assistants also friendly, thoughtful, kind and helpful and Dr. Tang the best!!!!! My only regret, I wish I had known about Dr. Tang’s office many years ago I would of avoided all those other bad experience with all those other dental offices! Would definitely recommend this office to anyone looking for a great dental office.

Dr Tang has one of the best chairside manners I’ve experienced. Very nice office and the staff from the reception area to the assistants are wonderful. They are upfront about all the work and fees needed. Very happy and recommend to friends in the area!

Anthony R. from Irvine, CA (Source: Yelp)


I’ve been a patient of Dr Tang for over twelve years. Although I no longer reside in Irvine I drive up to 40 miles and will continue to be a patient of Dr Tang. He is a caring, trustworthy and displays the highest level of professionalism in his office that includes a great office staff. The office staff has made changes in dental coverage a smooth transition over the years. I myself work in the Health care industry and exceeding customers Dental care expectations is definitely #1 at this dental office

Always have a great experience. Dr. Tang is professional and attentive. Even cleaning is done by Dr. Tang. The wait is almost none esp. when appointment is made ahead of time. PLUS the dental office is equipped with TV and movies which helps in dampening down the noise from the grinding and providing distraction.

Dr Tang and his team do whatever it takes to take care of their customers. They stayed late and reapplied a crown from a previous dentist by fitting me into their schedule. He is a perfectionist, caring and ever helpful. A great team I would highly recommend to anyone.
