Diamond Bar Smiles Dentistry

I’ve been going here for about a year now and I’ve always had a great experience. The staff are friendly and informative. Dr Ella always provides good care. I’ve spent hours at this office when I had major work done but the overall environment and genuine care from the people made the time pass as pleasant as possible.
I also trust that my teeth are in great hands and their new technologies make dentist visits quicker as they pinpoint problems with modern solutions.

Was hesitant to try this place out due to some of the negative reviews; but because of its location, decided to try this place out. Glad I did. This office has new technology and a friendly staff. Been coming here for a few years now. Dr. Chu is thorough, gentle, and has done a great job with my teeth.

I had an adverse reaction to the pain medicine prescribed. I went back and the dentist was annoyed. My brother had to call her in a new script. She didn’t know of the alternatives. This is a franchise type of dentistry where they have to milk the insurance for maximum amount they can bill then inform patients of the copayment after the fragments so you are stuck with a $ 1000 bill before you wake up from the fog.

I hate going to the dentist, seriously abhor every time I had gone any where else, but since coming here, I will not go anywhere else. They are always kind, very uplifting, and work with my schedule. They are also very giving-​at my work we were collecting care packages for the homeless and they donated oral care packages to include in my sets. I love this dental office!

I have been going to this dental office for five years. They have friendly staff and modern dentistry and great knowledgable Drs.
They have saved my gum from the periodontal disease, I had deeper scaling and laser done and ever since then my gum doesn’t bleed and my breath smells good. The periodontist told me I didn’t need any surgery. Now I just see my hygienist Andrina regularly to maintain it.
I am so glad they were able to save one of my tooth that my previous dentist in San Gabriel did a bad job on the root canal and open margin crown that caused infection. I was lucky that the Endodontist Dr Nguyen did a retreatment for me and Dr Chu made a beautiful custom fit Cerec crown for me on the same day. I have no pain ever since then. I love the fact that Dr Chu even called me the night after my appointment to make sure I am ok.
Even though I had to pay some money on top of my insurance, I think it is totally worth it. I rather save my teeth and have good oral health then cheap out on my health.

THESE PEOPLE ARE CROOKS! Friendly, professional staff, state-​of-​the-​art office but nonetheless crooks! In 2012 I was told many times that I needed «oral surgery with a bone graft» costing $ 1,500 (I have no insurance) by the periodontist, and that it just kept getting progressively worse by my inaction to get it done. So of course, their tactic worked and I decided to have the procedure in early 2013, a procedure that was not explained to me at all, just that it would last approx 1 ½ hrs. Well, the so-​called «surgery» lasted less than ½ hr from the time I stepped into the office; it seemed to me like such a minor procedure (a normal cleaning seems more thorough) that I never even realized there was an incision at all until I felt a small piece of string, which, btw, I had to cut off myself 3 weeks after the «surgery». I complained loudly and strongly about the cost, and eventually the office manager gave me a credit back of $ 600 saying she had checked around other offices and a refund was warranted, I was pacified. Shortly after, they started saying the same tooth needed a crown because the fit between the teeth was too large.
Recently, even though I take excellent care of my teeth, have no discomfort, bleeding, swelling redness etc, a different periodontist told me I now needed work in 3 out of the 4 quadrants of my mouth, including the original one from 2013; she called out several 7’s, 6’s and 5’s when doing her exam. Since I now had signed up for the «office plan», my co-​payment would ONLY be $ 5,300 instead of the $ 7,600 normal charge. When I told them they were crazy, the manager said that for the area that had previous work done, I would be charged $ 750 instead of $ 1,500. What a bargain!!! They seem to justify these exorbitant prices since the insurance companies pay them. So this time I went for a second opinion to a different periodontist that has good reviews on Unilocal (never told him anything about the diagnosis from this office), and law and behold… NO WORK NEEDED AT ALL. The worse number he called was a 4!!!
So if you want to pay thru the nose for unnecessary dental work (lasers, irrigations, antibiotic drops, deep cleanings, surgeries etc etc) this office is your place. As for me, I totally distrust them, feel they ripped me off, and will be changing offices right away.

Awesome experience! I knew I had some cavities I could feel it when I was eating sweets. Going in the office didn’t take long at all I was able to get X rays and treatment done in just one day! I was really nervous about getting a shot in my mouth but the assistant and doctor were super helpful in comforting me and explaining what I should feel and what was going to happen during my treatment I’m so impressed my mom and sister ate coming here as my referral! The front office is also amazing explaining the financial side of it. Overall very satisfied and will definitely be coming back!

DO NOT COME TO THIS PLACE, WORST DENTISTS I HAVE EVER BEEN TO, AWFUL AND GREEDY. THEY DO NOT CARE ABOUT YOU, THEY ONLY WANT TO DO UNNECESSARY AND TERRIBLE WORK TO TAKE YOUR MONEY!!! This place deserves zero stars because I was told I needed root canals, deep cleaning, a gum procedure of some sort, wisdom tooth removed, and fillings… ALL turned out to be unnecessary. They showed me an estimated bill for over $ 9,000 of work including insurance coverage!!! I said I don’t have that money, and had fillings done for $ 350 out of pocket and $ 878 taken for insurance.
Went to my old and reliable dentist in San Diego, turns out I didn’t need ANY of the work and the filling she did was done so poorly it was the reason my tooth was hurting.

I brought my kids here for a routine cleaning. The doctor told me that my daughter needed a root canal and sent me with a financial person to a separate room. They were charging me $ 1,800.00 co payment, I told them I don’t have that amount and my daughter has no pain so I think I have to wait, the doctor mistreated me and told me that I don’t care about my daughter, I had to pay $ 186.00 just for the x rays and cleaning plus the money they charged to my dental insurance… A few days later I took my daughter to another dentist and surprise!!! She didn’t need a root canal. It was only a cavity.

I was also in the chair when I was told I needed to sign off on $ 2,000 worth of gum care and $ 80 for xrays that had already been taken.
Very unprofessional and my wife and I will not be going back

Maybe it might cost me some money but I am really scared of going to the dentist from a bad experience I had. But the staff made my visit extremely smooth and comfortable. Thats what matters to me. Staff are really friendly and answers any questions.

They called me 5 minutes before my appointment to cancel, I was in the parking lot at the time. Then I was urged to wait several hours, no thank you. Setting up the initial appointment was nightmarish as they got it wrong several times.

AMBUSHED! Went here for a routine cleaning with a coupon for $ 60. While I was upside down with things in my mouth, the financial coordinator approached me for additional work that I have never had before — lasers, irrigation, etc. — saying it was required because I wasn’t flossing enough (I floss 2 – 3 times/​day religiously). Imagine my surprise when they said the cost was well over $ 2,000, which they would discount to $ 1,200. They did agree to a 10% discount for cash payment, but I’m pretty sure they are overcharging for unnecessary procedures. BEWARE!

I can Smile again.

The entire staff is very friendly and knowledgable. Every time I have an appointment I feel very comfortable and know that my teeth are receiving excellent care.

This place is excellent. Mi tooth was boyherin very much i called they put me in right away as in a emergency, made me feel very welcome very nice. doctor was amazing n explained everything she wus gonna do to take carw of mi pain inmi tooth. The doc assisent wus very nice sweet n kind very friendly. I wus nervous but she calmed me down and she had a great smile:) n the prices were good not over price. I would definitely come here again. THANK YOU

I have an appointment at 0700, the day before the appointment, I called the office to make sure the time of the appointment. I really don’t like the time cuz I need to take my kids to school. The response from office: you have to be here at 0700 cuz his schedule only works for 0700! So I came and turns out the dentist showed up at 0730 which is very unprof

My honest opinion: this place overcharges you and pressures and guilts you if you hesitate to accept their high-​priced recommendations.
My dental insurance sent me here, so I had no choice really. I will say that the office is very clean and modern, and their equipment is top of the line. The dentists and staff are very friendly to you, but I have decided to stop going here b/​c I believe they are ripping me off.
Admittedly, I’m not the best at flossing regularly… BUT my wife REALLY is. she flosses and brushes EVERY day very thoroughly. We have gone to the dentist several times a year for the past several years. For 5 – 6 years, we have ALMOST NEVER been asked to do any work outside of the routine cleanings, which usually are completely covered by insurance. Then we start coming here because we moved here. I would say we have paid maybe $ 500‑1000 on dental work in a year. «deep cleaning», «lasers», «antibiotic drops» all not covered by our insurance. When we hesitated about getting these services, they said that we would regret it, that we would pay more in the long run, the other services wouldnt be effective without the additional services, etc. It sounded like a trained sales pitch. The pressure was so high, we gave in.
Finally, I got fed up, I got a second opinion, and I was told that my wife and even I didn’t need ANY of these services, that the basic cleaning, covered by our insurance, was all that we needed.
I know this is pretty harsh and I do want to repeat that everyone was friendly. I actually think they are just doing their jobs as they are being trained to do. But I highly recommend that you find another place.

Like most of us, I don’t go to the dentist very often. Maybe when something bad is happening. Going in I was not very excited… I’m so impressed with Diamond Bar Smiles, I have to list all the amazing things about this place:
1. They did a deep clean with laser, which is just freakin great. My gums were red, receding and probably infected (I know pretty gross), but this procedure took care of that. Now they are pink strong, don’t bleed when I floss and THEY ARE COMING BACK. Every other dentist has been unable to do anything about this!
2. The staff here are so courteous and helpful! Dr. Peggy Chu is very experienced and professional! I’m not sure what other reviewers are smoking, but I had a great experience with her! The ladies at the front desk provide top quality customer service!
3. A ripoff? I don’t think so. You get what you pay for. There is high tech equipment, experienced and courteous staff and very high quality treatment.
4. I had all four wisdom teeth removed by their surgeon. I know the drawback is he only comes once a month, but trust me its worth it. No pain (I was asleep for the procedure), and the recovery time is great so far. It’s been one day, and I don’t even have to take pain killers! The whole surgery took less then 30 min!
5. My HMO from BlueShield covered most of the cost of each treatment.
This is as good as a dentist can get.
Thanks Diamond Bar Smiles!

DO NOT GO HERE!!!
1. The dentist, Peggy Chu, is greedy with money and over-​booked 4 clients at the same time.
2. Failed to confirm appointments for 2 services that were promised, and I had to come in the next day for the 2^nd service. Very inconvenient!
3. Due to her overbooking, she numbed my mouth and then made me wait for 25 minutes while she worked on her other patients.
4. When she returned to work on me, she failed to change her gloves and forgot to put any cover on my shirt.
5. Very unprofessional in appearance, looked like she just rolled out of bed!
