This review is long over due!
Dr. Brian is an amazing dentist. He loves what he does, he listens to your concerns and explains everything to your understanding. He doesn’t rush you into making decisions you’re not comfortable with. I wish they were more dentists like him. The office is nice and clean. The staffs are super friendly. I made him my family dentist because of all the good attributes he has.

You can’t get a better dental visit than this place!! Highly recommend.
I haven’t been to the dentist in years? Why because who wants to pay money to be hurt. That’s all I remember from my last dental visit. This place is the exact opposite. I had a deep cleaning and a tooth pulled to prep for a bridge and I seriously didn’t feel anything, didn’t even know when he pulled the tooth. The office and equipment is very professional and clean. All the staff is very helpful and knowledgeable. Thanks to this place my view towards going to the dentist has changed.

I have had nothing but amazing care and service here at commonwealth dental. I am usually seen by Dr. Nguyen but was seen by Dr. Tadang for an emergency walk-in. They are both very professional and thorough dentists. They communicate what they are going to do before each procedure and discuss pricing as well so there are no surprises. I appreciate how calm and gentle they are and have always felt at ease in the dental chair. Their services and recommendations have made my teeth in the best shape ever and my last visit had proven so … Dr. Nguyen told me I had no cavities 🙂 therefore I wanted to treat myself to some whitening .. which they also offer!! And at a great price. The office is always clean and is modern and each chair has a TV to keep you occupied – which is a nice touch. I’ve recommended this dental office to all of my friends and family with no regrets.

I was having some pain in my back tooth (…) so I decided to check this place out. I had an awesome experience with Dr. Tadang! Glad I came in to take care of a small cavity before it got worse. It was a quick and relatively painless procedure. I think I found my new dentist, highly recommend!!

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


Great dental office with a wonderful team of knowledgeable staff.  I came in as a first-time patient with some nagging pain in my molar and got it fixed right away.  The staff were brilliant.  The whole process from x-rays to the treatment was efficient.   As with most people, I am very apprehensive about going to the dentist for check-ups.  After this visit, I will definitely go here more often for routine check-ups.

Connor R. from San Luis Obispo, CA (Source: Yelp)


I’ve been going here for the past month, I got a cleaning done with x rays with Brian and he had noticed I need a couple of fillings. He worked with me and my insurance to get me the best affordable price as well as worked around my schedule perfectly. Today I got the fillings done and was out in an hour with 4 fillings with no pain. Brian is a caring guy who’s really good at his job. 10/10 would recommend.

Marieke N. from La Habra, CA (Source: Yelp)


Dr. Brian does an awesome job, he has done a lot of work already and I haven’t felt any pain whatsoever, not even from the anesthesia. I have recommended some co-workers already and they love him as well. I would highly recommend anyone to go and see Dr. Brian.

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


(…) My veneer came off all of a sudden in the morning of Saturday, so I had to find any dental office that opened on Saturday. Commonwealth Dental came to my attention, so I called the office to let them know what I had had that morning. The staff was so kind to answer all my questions and concerns. I made an appointment and went there in about an hour to get my teeth treated.
During the entire procedure, Dr. Brian made me feel so comfortable with his professionalism, thoroughness, and great care. I really appreciate it, Dr. Brian! I highly recommend Dr. Brian to anybody who is looking for a reliable professional.

(…) Dr. Tadang’s service, on the other hand, has totally taken me off guard. For one, I was able to watch NETFLIX while getting work done, he’s careful about anesthetics, pays attention to detail, provides quality work, and gives honest non-pressuring dental advice. Best dental experience I’ve had so far. Highly recommend!

Habib C. from Norwalk, CA (Source: Yelp)


I was in a bind and needed immediate dental work, they were closing in 45 minutes, and he took me in, while other dentists would’ve turned me away. Definitely a fantastic dentist! Very attentive and careful, willing to accommodate any needs. Highly recommend going here. As long as he stays around, I won’t be going anywhere else but here for dental work.

Elisha C. from Huntington Beach, CA (Source: Yelp)


Highly recommend Dr. Brian,  he is friendly, knowledgeable, and has great integrity. He also has a friendly staff. Anyone looking for a new dentist or want to switch dentist, he is your man.

Chinh Tran (Source: Google)


I switched between a few dental offices within the last few years but this office, by far, has provided the best in class service. The space was tidy and immaculate, the staff is friendly, brand new equipment, and I got to watch animal planet while getting my teeth cleaned 🙂

Josette F. from La Habra, CA (Source: Yelp)


Dr Brian and (partner dentist) are amazing  I visited commonwealth Dental for a regular check-up when I first came into the office I immediately felt comfortable there Dental Assistant KAT was very nice friendly and fast and very accommodating making me feel at ease Dr Brian is fair Dentist I recommend all my family to him you will love all of them as well!

Daniel T. from Huntington Beach, CA (Source: Yelp)


Being in the dental field myself, I have my reservations with seeing other dental professionals. However, Dr. Tadang’s combination of knowledge and skill makes me feel at ease every time I come in. His chairside manners make even the most nervous patients rest assured. I’ll make sure to recommend Commonwealth dental to all my friends and family.

Brad C. from Placentia, CA (Source: Yelp)


Fortunately got the mailer about this office and took a chance. After getting my checkup and cleaning everything from start to finish was awesome. Dr Tadang was friendly, quick, and knew what he was doing. It had been 3 years since my last cleaning and even with that sensitivity in my teeth, the doc didn’t hurt me. BIG plus, you get to watch Netflix during the cleaning!

Sara L. from Pasadena, CA (Source: Yelp)


I’m so happy I live nearby and found this dental office. I underwent treatment with Dr. Kim. She is so polite and is an amazing dentist! Very attentive to any pain that the patient might be feeling and thoroughly explains every procedure. I got two crowns and some fillings done here and I’m so happy with the outcome! The prices here are very reasonable and they make sure that the outcome is aesthetically pleasing.

Jacki O. from Fullerton, CA (Source: Yelp)


I really like Dr. Brian as he was a great demeanor and was very good with my 93 year old dad. He’s def honest and of the mentality to keep your real teeth.  His prices are very fair also. I’m a fan!

Joe F. from Fullerton, CA (Source: Yelp)


Like most people, I’ve put off seeing a dentist for years, but I decided to check this place out after reading a few reviews. I’m glad I listened as this is the best dentist I’ve ever been to. I’ve been here a few times now.  Once for a cleaning,  once for a cavity,  and I even had some cosmetic work done.  I had a pleasant experience every time due to Dr. Tadang’s skill and professionalism.  The sessions are short and painless, and as a bonus, you get to watch TV while getting worked on!
I’ve recommended all my friends and family to Dr. Tadang and they all agree that this is the best dentist in town.

Monique P. from Placentia, CA (Source: Yelp)


I am so glad I found commonwealth dental! They offer affordable prices which is perfect for people with no dental insurance (me!). Dr Brian did a deep cleaning for me and also did my fillings. He made me feel so comfortable and did a great job! He answered all my questions in detail and made me feel confident about my oral health.
If you’re looking for a new dentist, I highly recommend Commonwealth Dental!

Romuel Dave C. from Irvine, CA (Source: Yelp)


(…) First off, everyone in the place is super nice… you can’t walk anywhere without them smiling and asking how you are doing. If this were some other sales business, I already bought it. That feeling of comfort and ease is something rare to see in many dentistry offices.
Secondly, Dr. Brian is very professional, truly knowledgeable, and wants to make sure that you are comfortable and aware of the treatment. Whether it be cleanings, fillings, or more in-depth dental work, Dr. Brian will take care of you in the best way possible (…).

Samantha S. from West Covina, CA (Source: Google)


Everyone is so friendly & the office is extremely clean & organized. Dr Brian helps tremendously with my anxiety surrounding dentists! I have had horrible & traumatizing experiences in the past and he’s very gentle and aware of it. If he senses the slightest bit of discomfort he stops. He also has quick reflexes! Between anxiety & sensitivity in my mouth I can tense up and/or move & I feel horrible but it’s like he has a sixth sense and is able to stop whatever he’s doing before any damage is done. He’s very kind and great at his job. My health insurance hasn’t provided many great doctors but they’ve given me a great dentist and I am so grateful for that. I’m eventually planning on bringing my baby here too once his teeth come in. The dental assistants are also very patient and kind. 1000% recommend him & his team!

Kimberly B. from Fullerton, CA (Source: Yelp)


Personally a visit to the dentist always puts me on the edge–Dr.Brian Tadang changed that for me completely! All my work was done thoroughly and efficiently, always a warm welcome and given the current pandemic very comfortable & safe. They require masks to be able to enter the building, as well as having your temperature taken before being seated! Having to pay for any type of treatment is also pleasant since they did accommodate a ‘payment plan’. This is also the first practice I have ever seen that’s so modern/clean, including having a TV set up streaming Netflix while you get your work done! Everything about this office is amazing, and of course the staff & Dr. Tadang make the experience THAT much better. Look forward to coming back in 6 months

This place is AWESOME. Dr. Brian is very professional and kind. He explained really well and kindly. Since we do not know that much about dental procedure, he explained well to understand. And the office is really clean and new! Highly recommend! Thank you so much Dr. Brian.

Robert I. from West Covina, CA (Source: Yelp)


I’ve been here a few times and have had a great experience!  Everyone was so friendly and the office was very clean.  Dr. Brian and Dr. Kim were very thorough in explaining the treatment which put me at ease. The assistant, Sam also made me feel very comfortable. I even referred one of my friends that didn’t have any dental insurance and they were able to help her out with reasonable prices. I would definitely recommend this office to anyone looking for a dentist!

Azarel C. from Santa Ana, CA (Source: Yelp)


Dr. Brian and his staff are very friendly. Always on time. My procedure is fast and easy. I’m usually very nervous around the dentist but Dr. Brian makes you feel comfortable every time. I would recommend this place to anyone looking for a good honest dentist.

(…) Dr. Tadang and (partner dentist) make the dental appointment very enjoyable! They are both very knowledgeable and are open to being asked questions. Best of all, they are straightforward with you and only recommend the services you need. Additionally, their office is very modern with the latest dental tools, and there are TVs for each patient to enjoy Netflix while their teeth are being taken care of. So you can continue your binge-watching of the latest season of your favorite show AND check off your semi-annual dental visit. Win-win! There are also a number of excellent restaurants nearby to test out your teeth after your appointment.

If you are in search of a new dentist, I highly recommend this office!

Thuy-Vy N. from Santa Ana, CA (Source: Yelp)


Dr. Tadang is very knowledgeable and made my dental exam and cleaning very comfortable. I really appreciated how gentle and thorough he was because we ALL know how scary and daunting a dental visit can be. On top of the awesome care, the office is clean, modern and updated, exactly how a dental office should be!
I highly recommend Commonwealth Dental! If you’re in the area and looking for a new dentist or just want a better one, come here! You won’t regret it… And you might actually look forward to your next dentist appointment 😉

Richard T. from Hacienda Heights, CA (Source: Yelp)


(…) The place and equipment looked brand new. I got (Dr. Tadang) and he was nice. The cleaning was painless and he found a few cavities. Decided to take care of them because he had the time and even that was a good experience. He took his time with all the procedures which meant little to no pain. Would go back and recommend.

Brenda W. from Fullerton, CA (Source: Yelp)


Dr. Tadang was very thorough, explained everything, and has a wonderful staff.  When I was reading his bio on the website, I was impressed that he has done work with the underserved in Las Vegas, and STILL continues to serve them one day a week.  This is a doctor with his heart in the right place!  I have a slight fear of the dentist, and he walked me through everything so that I knew exactly what to expect.  There are TV’s on the ceiling as a nice distraction while you’re having the work done, The office is bright, cheery and extremely clean.  I promise you will have a wonderful experience with Dr. Tadang.

Rica M. from Los Angeles, CA (Source: Yelp)


Husband and I have been going to Commonwealth Dental for a year now and the service has always been consistently great. The clinic is clean with a modern vibe, and you can watch a movie during procedures. Dr Tadang, (partner dentist) and their team are efficient yet thorough with their work, most importantly, they educate their patients during their visit. I highly recommend them.

Eddie Bryan (Source: Google)


Dr. Brian is the best. The staff is friendly and professional. The rooms are clean and the equipment looks new. I know I am in good hands.

Clay P. from Los Angeles, CA (Source: Yelp)


(…) Couldn’t have been happier to find Dr. Tadang’s office which was the exact opposite.  His office was bright and modern with a young and friendly staff which immediately put me at ease.  Dr. Tadang was fast, efficient, and very professional.  Already have my next appointment booked for a 6 month follow up, not going to wait until I break my mouth again!

Christine T. from Irvine, CA (Source: Yelp)


I just had my first appointment with Dr. Tadang this week. When I first walked in, I was greeted with a friendly smile from the staff. I noticed that the office was very organized and clean, which I appreciated! When Dr. Tadang went over my x-rays, he was very thorough so I could understand what was going on. Most of my past dentists don’t take the time to explain to me in as much detail, so I really appreciated that he did this! I would definitely come again and recommend anyone looking to check this place out!

Jocelyne M. from Downey, CA (Source: Yelp)


Dr. Brian has perfected the experience of fully enjoying seeing your dentist. His professionalism, friendly staff, and atmosphere exceeded my expectations. He guides throughout the procedure while making sure you are comfortable.
I would highly recommend seeing Dr. Brian and Dr. Brian for all types of restorations, extractions, and cosmetic work. I am very impressed with how natural my fillings look without any post sensitivity issues. Puts you at ease knowing dental work can get tricky! Thanks again for all your work, Dr. Brian!
