Check out what some happy patients are saying about us:

Priscilla K. from Buena Park, CA (Source: Yelp)


The experience was already pleasant before I even went in. Both of the front desk ladies were polite and professional when answering the phones AND kept their promises. Sarah Garcia, at the front desk, went out of her way to answer all of my questions, and if she didn’t know the answer, she told me she would call me or email me when she found the answer… and she WOULD find out and call me or email me later. She made sure my files from my last dentist were sent over promptly and kept in contact with me daily, giving me updates and never left me hanging or made me feel like a nuisance. I really, really felt taken care of.
When I went into Healthy Smiles, I felt comfortable because it was clean and they had the latest equipment – the last dental office I went to had very old equipment, and the staff there was friendly, but almost too friendly and too laid back to the point where it was unprofessional. It almost felt like a room full of students/interns – maybe they were; I don’t know. Anyway, I didn’t feel this way at all @ Healthy Smiles. I felt like I was in a friendly, professional, and clean environment.
Dr. Lu is probably the best dentist I’ve ever been to. He made me feel safe. I went in to get some cavities filled, and I was super nervous because I hate needles…especially near my mouth. Dr. Lu could sense I was nervous and was very patient with me and explained everything in detail before he did anything…and he was actually GENTLE which isn’t something I’ve experienced with many dentists. He made me feel like an important person, not like a number, not like someone he wanted to get out of his hair. AND he called me about 2 hours later and asked me how I was feeling!!! Never have I experienced this top quality care anywhere. I will definitely be making Dr. Lu my primary dentist. Thank you Healthy Smiles for making me feel safe and taken care of!

Dr. Lu is an exceptional dentist. What I mean by exceptional is that he is non judgmental and offers suggestions on the best way to have a healthy smile! I have had several fillings lately and each time he is patient, kind and compassionate in his approach for me to find the best way to prevent cavities. I also had a crown done this week and he answered the phone after hours, scheduled my appointment the next day and was able to start the crown that same day! He was very sensitive to check in with me that I did not feel any pain during the procedure! I had absolutely no pain afterwards or soreness whatsoever! Remarkable, I am so grateful for his attentive staff and ease to not only schedule an appointment but for the highest level of care given through out the entire procedure. Dr. Lu even called me that same night to check up on me.

Dr. Lu is super nice and professional. My whole family see Dr. Lu for all of our dental appointments. We all had great experience here. Highly recommended!

Julie V. from Fountain Valley, CA (Source: Yelp)


I’m still a pretty new patient here but so far what I have to say is that the staff at Healthy Smiles Dental Center really know how to make a person feel comfortable and cared for in a setting that is usually associated with high pitched drills, cold halls and pain.

This office is far more calming than other places I’ve been to, and Dr.Lu has always been friendly and thorough with both his procedures and explanations for treatment.

Barbara M. from Pensacola, FL (Source: Yelp)


I have been very pleased with this office for several years and confident that when Dr. Lu took over the practice that I would be happy with the change.

Dr. Lu is knowledgeable and professional. I’m confident in his abilities. His chair side manner is incredible. His interest in me is genuine and he takes the time to explain each step of the procedure.  When I had a simple old filling replaced, he uncovered that I needed a root canal. I was surprised to learn that he could do it right then.  In the past I would have had to make an appointment with a specialist,etc. he could have asked me to come back another day. Instead, he did the root canal right then and I returned the next day for the crown work. He was able to work me in during his regular schedule the next day.

I highly recommend Dr. Lu as well as his team of Candace,Tina , Andrea and Faviola.

Thomas S. fro mSimi Valley, CA (Source: Yelp)


Really happy with the time they took to make sure my bite was right with my new crown, the meticulousness of their oral hygiene examinations and concerns about all of the little details. Dr. Lu and his assistant Lisa have been great

John D. from Monrovia, CA (Source: Yelp)


If you’re looking for amazing dentists with lots of knowledge, updated equipment, and a friendly staff then, you need to check out Healthy Smiles. Dr. Lu was very friendly and informative. Tina was my dentist that cleaned my teeth and she was amazing. Both her and Dr. Lu explained to me each step in my deep cleaning process. I felt at ease and the best part was that I didn’t feel any pain. My wife and I will definitely be coming back in the near future.

Dr. Dich Lu definitely exceeded my expectations. He loves what he does and he’s good at it! I’m usually not one that loves to go to the dentist, but I’ll definitely come back. I got my fillings done and it didn’t hurt at all. He would ask me if I am doing okay and make sure that everything went smoothly. The staff is also very friendly! When I walked into the door they would greet me. Now that’s what I call awesome service!

Cristiano B. from Huntington Beach, CA (Source: Yelp)


Thank you so much Dr. Dich Lu great job! I highly recommend his dental services always efficient and clean !

Angelique F. from Long Beach, CA (Source: Yelp)


Great service. Great staff. Clean and modern office. Dr. Lu is very thorough and gentle. He takes his time and doesn’t rush you. Everyone is friendly and helpful. Love the TV monitors at each chair. Appointments always run on time too. I never have to wait more than a minute or two upon arrival. I appreciate that before doing extra services, they check insurance and costs and ask for your approval before doing it. They also don’t pressure you into saying yes to those extras.

Matt B. from Santa Ana, CA (Source: Yelp)


For years my wife and I have had trouble finding a dentist we both felt good about. My wife has been going to Healthy Smiles for a while and encouraged me to try them. I’ve just finished my first (deep) cleaning and had a really good experience. Maybe this time I’ll actually make it a regular thing!

Monica Hernandez (Source: Google)


I always get good service. They pay a lot of attention to you and personalize it. They always give you the better choices for your smile. I recommend this office to everyone.

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


I have always dreaded going to dentists, but Dich Lu and his staff makes it as pleasant of an experience as possible.  Dich is extremely professional and knowledgeable.  Plus – he is a genuine all-around nice guy!.   He gives good advice and does a great job.  You can tell that he really cares about his patients as well as the quality of his work.  The location is very convenient, the office is as clean as can be.  Highly recommend!

Maritza G. from Costa Mesa, CA (Source: Yelp)


Dr. Lu and his wonderful staff make my visits to the dentist less scary. Dr. Lu walks me through everything that gets performed on me and makes sure I’m as comfortable as possible. I appreciate the staff checking in on a regular basis to ensure I’m not in any discomfort during my procedures. I’m very happy with the quality of treatment I’ve received at Healthy Smiles — thanks Dr. Lu!

Lesley B. from Carson, CA (Source: Yelp)


Dr. Lu and his team are amazing! I feel that Dr. Lu is passionate at what he does as he truly listens to his patients. I agree with the comments below. His bedside manners is top notch. I love that he’s meticulous and is a perfectionist. I can’t wait to go back and see the final result of my dental work. I’m glad I found Dr. Lu and I will definitely recommend him. He also makes sure to check up on you after your visit. That definitely sets him apart from others. He goes above and beyond to make his patients feel comfortable and helps me to make the right decision.

Dr. Lu and his staff are excellent. I had a chipped tooth over Christmas and luckily they were able to fit me in right away on the day after Christmas. The service was excellent with minimal discomfort. Dr. Lu made sure to explain what was going on with my situation and even called that night to check and make sure I wasn’t having any issues. I’ll definitely be going back.

Adriano F. from Riverside, CA (Source: Yelp)


My tooth had been infected for months, after visiting many different dentists, Dr. Lu took the time to explain my options and made everything possible to save my tooth and to treat the infection.
The assistant and front desk people are considerate, caring and great professionals.
Thank you Dr. Lu for calling me back next day to make sure I was doing fine.

There are too many nice things to say about this place! From the people at the front desk (Sarah!) to the dental assistant to Dr Lu. I couldn’t have asked for a better experience – They are utter professionals and made me feel comforted with my wisdom tooth extraction process and healing – Truly grateful we found you guys!

 Hank A. (Source: Google)


I do not normally enjoy going to the dentist but I definitely look forward going to see Dr. Lu and his staff. My family and I were patients of the former dentist and when she retired I was curious as to how things would go with the new guy. I was pleasantly surprised by his polite manners and his staff were fantastic as usual. This office has a unique feel to it and everyone from the front desk to the hygienist, Tena, to the assistants are amazing! They treated me for my sleep apnea problem by making me a small comfortable mouthpiece so I no longer have to use a C-Pap machine. I wish the new dentist best of luck!

Catherine L. from Bellflower, CA (Source: Yelp)


My husband and I both have been diagnosed with sleep apnea for about two years. Hubby didn’t want to either of us to use the traditional CPAP machine. He discovered Dr. Lu’s commercial on the radio, had me make an appointment for a consultation,  and we have stuck with Healthy Smiles since! Dr. Lu and his wonderful staff have taken care of all our dental needs along with resolving our sleep apnea with the oral device. Lucky for us, our insurance covers everything!

Jamie S. from Costa Mesa, CA (Source: Yelp)


Have you ever had your dentist call you at 7 pm as a courtesy to make sure your teeth felt good after a procedure?  I was shocked when I received the calls after 2 big appointments.  Dr. Lu is setting the bar for great service by a dentist.  He runs a very relaxed atmosphere, is super gentle and does a great job explaining every move he is making.  He has built my confidence high enough that I want to bring my children here for their first pediatric dentist appointments.

Kalo K. Los Angeles, CA (Source: Yelp)


Dr. Lu and his assistant, Lisa, worked together efficiently and seamlessly as a team. They definitely have this procedure well known, like clockwork working together.

Karen is so very compassionate, careful with detail, warm and welcoming! She took care of us, and found a financial plan that works best for us. People like her warms my heart of joy.

Dr. Lu did a perfect job on my husbands new smile, with Lumineers! 😀

Marcus X. from Irvine, CA (Source: Yelp)


I found Healthy Smiles through a lot of searching on the internet. I needed somewhere that accepted my university’s insurance, and had a capable/experienced dentist. There are so many clinics to choose from, and the reason I came here was because the reviews I found indicated he is not only a competent dentist but a friendly person.

I’m happy to say Dr. Lu fulfills all the criteria I deem important. He cleaned my teeth thoroughly, explained to me problems I have and may face depending on how I proceed to take care of my teeth (both by myself and procedurally vis-a-vis professional care). I did not think there was any misinformation, as I had experienced with other dentists elsewhere. My previous experiences with various dentists include those either completely incompetent/awful or simply didn’t care for anything other than how much they can charge.

Dr. Lu answered all of my questions concisely and precisely. He was courteous and treated me with the respect of an intelligent adult, which I appreciate. Furthermore, he gave definitive scientific bases for why certain procedures should be followed with regards to dental care, oral hygiene, and overall preventative measures to keep one’s mouth in good condition.

My impressions of Dr. Lu are such that he will be able to intelligently answer any questions/concerns I may have in the future. Any medical professional should be able to convey all the implications for any procedure the patient chooses to undergo or forego. After all, how can a patient make an informed decision if his doctor keeps relevant information away from him? Simply having a license is a necessary but insufficient condition to being a good doctor.

This has been my best dental experience so far.

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


Found this place through Zocdoc and the online recommendation didn’t fail. Dr.Lu and his office do stellar work. They are super on top of scheduling appointments and reminders. Whenever I come in I barely have a wait before being attended. After getting work done on my molars I am very happy with my results and much more comfortable with my smile. Their recommendations for future work are always well described and never pushy about it. The office is small and located around a shopping center in Santa Ana near the famous south coast plaza. I am glad I was able to find a new dentist that I can feel comfortable with and keep visiting for years.

Alice L. from Garden Grove, CA (Source: Yelp)


The staff and Dr. Lu are amazing. They are very friendly and professional. Dr. Lu is very diligent in his work. I can’t say enough. Highly recommended for anyone who is looking for a great dentist for cosmetic teeth work.

Richard Lopez (Source: Google)


I’m super stoked I made the choice to go here. Everyone is friendly, attentive and professional. I won’t be going to another dentist until I have to move out of SoCal. P.S. I got to watch Speed while getting worked on – rad!

Cristine M. from Orange, CA (Source: Yelp)


Dr Lu has been my dentist for 4 years now and I’ve always had a great experience. Just recently finished my Invisalign treatment and I’m very pleased with the results. I highly recommend Healthy Smiles Dental Center and Dr Lu.

Tim W. from Santa Ana, CA (Source: Yelp)


This dental office always feels like I’m visiting family. They are super friendly and make going to the dentist easy. The doctor is great at explaining things to you and he and his team sort of make me wish I could visit the dentist more often (although I’m glad I don’t actually have to do that). I highly recommend this office.

Suyue Z. (Source: Zocdoc)


I did my wisdom teeth extraction with Dr. Lu. He’s very calm and tentative to my needs. I was quite nervous, as I haven’t done any extraction work in adulthood. Thankfully, I am feeling good both during and after the operation.

Daniel W. from Santa Ana, CA (Source: Yelp)


Dr. Lu is perhaps the best dentist I’ve ever had. His entire staff is wonderful and he is obviously a superbly trained, quality dentist. I will never go to another dentist!

Jacqueline B. from Garden Grove, CA (Source: Yelp)


A family member recommended this office to me when I was having a brutal toothache that kept me awake all night.  This office was able to squeeze me in for an emergency appointment.  I had seen a previous dentist who referred me to another specialist to take care of my painful tooth which needed a root canal.  Luckily, this office does most procedures so I did not need to go to another doctor.  They even worked during their lunch time to get me out of pain and to make sure I could sleep that night with any throbbing pain.
Dr. Lu is a very compassionate and professional dentist. His entire staff exemplifies this manner and conduct. You will not find a better dentist nor an unbelievable staff. 🙂

Lisa R. from Santa Ana, CA (Source: Yelp)


Dr Lu and his team are Amazing!!! He is a fantastic Dentist, gentle, explains everything and is very knowledgeable and knows what he is doing.  I have had a issue with an implant that was installed by another Dentist and had complained for years that it was killing me and I just kept getting the same answer..there is no nerve there but Dr Lu took me seriously and is getting to the bottom of the issue and he is in the process of fixing it, Hallelujah!!!  Do yourself a favor and go to Dr. Lu you will not regret it I promise!!

Sarah G. from Costa Mesa, CA (Source: Yelp)


I had a temporary filling from another dentist fall out and I had no idea what to do! I called and they were able to take me the same day within the hour. I felt completely comfortable and the staff went above and beyond to fit me into the schedule! I’ve been back for fillings and teeth cleanings since.
Dentist visits can be scary….but I absolutely love seeing everyone here and I have complete trust in them.

Kate W. from Huntington Beach, CA (Source: Yelp)


Dr. Lu and his team helped me through my Invisalign treatment and it was an absolute delight working with them. They were very attentive through the whole process and always talked me through my options so I felt comfortable making each decision. With orthodontia behind me, I look forward to visiting Dr. Lu and his team for regular cleanings. I’ve never had a better dentist!

Brigitte R. from Santa Ana, CA (Source: Yelp)


Loved the atmosphere of this place. It’s very soothing and positive. Great for nervous patients. Front desk is very helpful and Dr. Lu is very thorough and attentive to the needs.
