Check out what some of our happy patients are saying about us:

The women at the front desk were extremely helpful with providing not only the information for my current and future visits, but they also helped to keep my son from running around like a maniac. They provided him with some cartoons and fruit to eat. They were so helpful! Dr. Hsieh was very thorough with my initial visit and setting me up with the proper specialists to fix the current issues I have with my smile. I’m a little fuzzy on the oral surgeon’s name but the entire procedure was so quick that I was surprised I was only in the office for 45 mins or so. That includes filling out paperwork and extracting 4 wisdom teeth. Next was the endodontist, which I am currently working with to fix a tooth that is discolored due to trauma. I’m seeing such amazing results that can’t believe! Finally after 4 appointments and maybe one or two more, I’m on my way to the prettiest smile I’ve had in years. It’s a long drive for me since I’m about an hour away, but well worth the trips. Also, I absolutely love Robyn. She’s been with me the entire process and I couldn’t thank her more. It’s comforting knowing someone is there to listen to me and make sure my needs are met when it comes to finally being confident in my smile. I love this place and would recommend it to anyone. I will never be afraid of the dentist again.

Always helpful and greeted with a smile. Waiting room is fine for a dentist office with water and a tv. Dr. Hsieh is an excellent dentist who will make you feel extremely comfortable. It’s just a far drive for me. But worth it.

Very friendly and professional staff.
Dr. Hsieh sits and listens intently on a one-to-one basis. Exceptionally caring and friendly! ☆☆☆☆☆
Sharon, the office hygienist is super sweet which makes for a quick and easier teeth cleaning session.  Thank you everyone!!

I went to this office on Thursday for consult after having  a bad experience with my past dentist of over 20 years. I talk to Doctor John for awhile. He is a great guy super personality. Most import very skilled and talented dentist up to date modern technics with in an hour he repaired my teeth to far beyond expectations he did all the work himself while we sat and talked with him and the girls He truly likes what he does and takes pride in it was more like a social setting then a dentist office. Him and his staff are super people I highly recommend Doctor John and his staff and the prices are beyond reasonable .

Dr. Hsieh saved my life today. I’m a father of five and a hard-working man. I do my best to take care of myself and my family. I had an emergency root canal this morning, I contacted Rancho Cucamonga smiles at 8:30 this morning, and I was sitting in the chair by 10. I had a botched root canal done in 2011. Dr. Hsieh fixed it and gave me a play-by-play the whole time! Last night I had come to terms with just pulling the tooth. Many thanks to dr. Hsieh, and everyone on Rancho Cucamonga smiles Dentistry team!

Dr. Hsieh is fantastic, and members of my family have seen Dr. Manal. Really great. You can fill out paperwork ahead of time to save you time, but the staff is very pleasant and accommodating. I never seem to wait long when I show up for my appointments. Also, I don’t feel they’re trying to push costly treatment plans.

Jennifer S. from Rancho Cucamonga, CA (Source: Yelp)


I absolutely love this place.  The front desk staff is always very friendly and accommodating to my crazy schedule.  This office offers evening appointments which really helps out a lot.  Dr. Hsieh is awesome, he always makes me feel very comfortable.  I have recommended this Dental office to my friends, family and co-workers and they all love it too!

Ray-n-kimi H. from Rancho Cucamonga, CA (Source: Yelp)


First of all, we would follow Dr. Hsieh anywhere he went!  He is personable and takes pride in his work.  Honestly, my whole family looks forward to our visits!  His office staff is amazing — friendly and welcoming. His assistants make you feel so comfortable.  So, when people say they avoid the dentist, I am seriously shocked!  Our visits are enjoyable — and we get really good, quality care for our teeth.

Kimberly M. from Rancho Cucamonga, CA (Source: Yelp)


This review is long overdue! Rancho Cucamonga Smiles has been our family’s dental office for the past several years and we will never go anywhere else! We had tried other local dental offices and weren’t happy at all! I have real anxiety at the dentist office, but Dr. Manal immediately put my worries at ease! She is gentle, personable, kind, and caring! I could go on and on! She has changed my mind about going to the dentist! I love her! She and Dr. Hsieh have gifted hands as they have both worked on me, as well as my husband and daughter, and have always provided all three of us with virtually PAINLESS experiences!! The entire office is warm and friendly, filled with just great people! I encourage everyone to give this office a try, especially if you have any fears or worries about your dental visit. Just let them know you have anxiety about visiting the dentist and they will be 100% understanding! Thank you so much Dr. Manal and Rancho Cucamonga Smiles for being my forever dentist!

I’ve been following Dr. J. Hsieh for 10 years. My son and I have no complaints. He is professional yet friendly. He is interested in the long haul, not just the dental issue at hand. My son has been a handful in regards to dental hygiene and Dr Hsieh is patient and encouraging with him. He is also not pushy in regards to large procedures. At one point, I did not have dental insurance and he told me I could wait for my procedure until my new insurance kicked in. On the other hand, if you need a procedure, he gets it done that day. It may take some time because he does the work around his other appointments, but you don’t need to come back and waste another day to get the work done. Another thing I like is how socially responsible he is. He is involved with many charities. Yesterday the office was full of donations to charity. He also has specials, like now he has 20% off if you donate a gift to toys for tots.

I have had the best experience at Smiles Dentistry! From implants put in to cleaning to small cavities done. John and his staff are great. Natalie is the best and the girls up front are so accommodating even when I blow off my appointment.

Ivan D. from Fontana, CA (Source: Yelp)


Far beyond 5 stars. Me and my family  have been with Dr. John Hsieh and his fabulous team over 8 years . They provide  the best care every time. He Is a Dental wizard doing his work and taking time to answer in debt every question asked. Wish him and his team longevity and new highs in Dental medicine.

Takasta T. from Ontario, CA (Source: Yelp)


Excellent Dentistry!! My past dental experience’s have been sub par at best, however after coming to Smiles Dentistry that has changed. The staff were awesome! They were Very friendly and made me feel comfortable the whole time. Dr. John Hsieh was easy going and gave me some excellent feedback and consultation.

Diane F. from Rancho Cucamonga, CA (Source: Yelp)


This dentist office is wonderful! There have been times when I arrive and I have to wait 20 or 30 minutes but to me, it is worth the wait! Natalie is my hygienist and she is so quick and thorough, Dr. Hsieh if so knowledgeable and thorough explaining everything just totally took all my dentist anxiety away. My last visit I needed to see dr. Manal because of a sudden situation. She put on a new crown and I didn’t feel a thing she was so sweet throw the girls explained every little step that they were doing during the procedure.

Leesa C. from Fontana, CA (Source: Yelp)


First off I want to say how amazing this place is. The front office staff is very welcoming and super friendly. Leah checked me in and was so nice and kept me up to date on when I would be taken back to see the doctor. Karolina is always so upbeat and full of energy and makes the visit so easy. All of the front office staff members make you feel so comfortable like they have known you Forever. Dr. Hsieh is Amazing and explains all treatment in detail (which is very helpful when you don’t understand dental terminology) the easiest part is they make crowns there in office in only one visit which is very helpful when it’s hard to take time off of work. I found my new home at Rancho smiles dentistry!!

Beatrice P. from Fontana, CA (Source: Yelp)


I have been with Dr Hsieh for a few years and he and his staff are great. They are always smiling, kind and ready to help.  Carolina and Audrey keep me smiling in the lobby until I get called in. Dr Hseih has been a great dentist and takes good care of my teeth. He is pleasant and very thorough. His recommendations have helped me have healthier teeth and a more confident smile. Dyana is my hygienest and she doesn’t miss a thing in between my teeth. She does a great job and my mouth feels very clean. She is serious about her patients flossing  and  she is very nice.
Everything  is very very clean and always smells great.

First visit to the dentist in a long time. I was emailed a form to fill out for my dental history. The receptionist knew my name and greeted me as I walked in. I sat next to someone else waiting and asked how they felt about this location and they gave very good praise, that which made the receptionist blush a little. I spoke with John Hsieh, DMD and gave him a formal breakdown of the issues that I came in for. I was asked to take X-rays, in which I was greeted by Cassandra, of whom was very candid and a great conversationalist. We chitchatted throughout the X-ray procedure, after which I was taken to a side room after a brief wait for John Hsieh, DMD. Once John Hsieh, DMD was ready, we discussed the X-rays and the severity of the issues at hand. He was very clear in the descriptions of what he saw. I cannot stress the following enough: John Hsieh, DMD was VERY clear in explaining existing issues and future concerns with my teeth, and not once really ever disregarded a question nor made me feel like I should not have been there. He was very patient, just like the rest of the staff, and I was very happy with understanding what procedures would be involved upon my return. I am scheduled for an appointment on April 9th, 2014, in which I hope to finalize this review and upgrade them from 4-stars to 5.

Dr. Hsieh gave me the PEFECT SMILE.  All my life I have suffered with bad teeth and would never smile is pictures. Every doctor I ever went to never addressed my problem or even offered a solution.  Until Dr. Hsieh told me he could replace my six front teeth with crowns.  At first I was nervous about the crowns looking fake or that I would hate me smile even more.  He took the time to address my concerns and reassured me he would make me the perfect smile that also looked totally natural.  I went in and he replaced my six front teeth with temporaries while he sent out my crowns.  My temporaries were so much better looking then my original teeth. I was scared the temporaries would fall off yet again his team reassured me they were not going anywhere sure enough less than two weeks later my crowns were in and my temporaries were still holding on strong. As soon as I looked at them I knew I had made the right choice. It only took two visits to get the smile I had only dreamed of having.  I now smile in every picture and have so much more confidence.  I could never thank Dr. Hsieh and his team enough for being so amazing at what they do.  Now everyone compliments me on my prefect smile and I recommend everyone go see him.

I drive from Los Angeles to get all of my dental work done here. In Rancho Cucamonga. That’s how much I trust the folks at Rancho Cucamonga Smiles Dentistry. Upon arrival, I was greeted with a warm welcome and friendly smiles from the staff. I had a later afternoon appointment and was able to get started even before my scheduled time. (Score!) I’m not the best when it comes to my dental hygiene so I wasn’t surprised when I was offered the deep cleaning. Sharon was the hygienist who took care of me. She was all smiles too. (Everyone is super friendly here!) I was a bit nervous and was expecting a lot of pain but the whole process was a breeze, especially compared to my past experiences elsewhere. After my cleaning, I felt like I’d finally found a place that I wouldn’t have to DREAD coming back to for regular cleanings! (Ask for Sharon!)  Next up was Dr. Hsieh to take care of my cavities and crown. He knocked out the cavities pretty fast without almost any sensitivity. (That’s big for me as I have pretty sensitive teeth) When it came time for my crown, Dr. Hsieh removed my old/outdated crown and sent someone in to do a 3D mapping of area where my crown would be. I was pretty impressed when they told me that my new crown would be ready in 20 min or so. I was used to having an old school mold done and having to come back after 3 weeks for the fitting. This was when I realized that these guys are really on their “A” game with service AND high tech equipment. All in all, I’m a very happy camper and would highly recommend them (Already have referred several friends/family!) to anyone looking for some friendly, high quality dental care!


We try to provide a friendly and professional environment where the patient can feel comfortable. I always educate my patients about their dental treatment as if they were my own family. Every treatment is done with the utmost care and attention to detail. Our team always makes an effort to follow up on each treatment and ensure the patient's comfort. I feel even in the smallest situations I can make a big impact with a patient, and it doesn't have to be any cosmetics or full mouth reconstruction. I had a patient with a terrible dental phobia that came in last week and we only did one filling and her phobia was lessened. She is now considering coming back for some cosmetic dental work.
