I have been coming here for years and wouldn’t dare to go anywhere else! Doctor Moeinolmolki is amazing and the staff always takes such great care of me. She’s honest and trustworthy and the only dentist I have ever gone to were the experience is painless! I had three fillings down today and left with a smile on my face which is a rare experience for a dentist visit! I highly recommend giving Nu Smile a try you won’t regret it!!

10/10 best dentist ever. The staff is awesome and personable. I was terrified of the dentist, but now I love coming here. Painless, friendly, affordable, I don’t know what more you could ask for in a dentist.

I put dental care off for way too long, when I finally got the courage to go I was referred to NuSmile Dental Center by some friends. What a great experience, Dr. Moeinolmolki is very professional and made sure I felt comfortable before I sat in the chair. They offer a clean, friendly environment and their services are top notch. Now I go for regular check ups and only wish I had found them sooner. My smile looks better than ever, thanks to everyone at NuSmile Dental Center

I would recommend this dental office to everyone! I never went to the dentist growing up and I was so nervous to go as an adult. They were so comforting and kind. Now I am on a schedule for teeth cleaning and I have learned so much! You don’t realize how much you need to go to the dentist until you go! Check them out, Lily & Dr. Sepideh Moeinolmolki are who I go to and I love them!!!

Everyone here is very helpful and informative. They know what they are doing and let you know what is going on as well as what will be needed in the future and the options available. If you are looking for a dentist, as I was this is the one to go to. You will not be disappointed. I will be coming here for all of my future dentistry needs.

Everyone at NuSmile are awesome. I have a very real fear of dentists and they helped me feel comfortable. I would highly recommend them!!

Mike T. from Santa Ana, CA (Source: Yelp)


I won’t lie, I get nervous when i hear the word “dentist”, but Dr. Moeinolmoloki and the staff at Nu Smile really changed my mind about getting dental work done. She’s very fast, precise, and efficient in her procedures – not to mention painless. Best dentist ever!

Sina M. from Aliso Viejo, CA (Source: Yelp)


Dr. Moeinolmolki and the entire staff are absolutely wonderful. Dr. Moe is very caring and a very hard worker. She makes sure that her patients are 100 % satisfied. I went to Nusmile to get a Snap-on-smile. From taking my teeth impressions to working with Denmat (company that makes the Snap-on-smile), to making additional adjustments to my Snap-on-smile once it arrived, Dr. Moeinolmolki and the staff did a terrific and thorough job. The entire staff will make you feel right at home and they really take care of their patients! I couldn’t be more satisfied with my experience and my new Snap-on-smile! I would highly recommend Nusmile Dental Center to anybody.

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


I’ve always been scared of the dentist since I was little. But this is one of the best dental offices. Everyone is so nice and caring ! I’m glad my co-worker told me about this dental ! She told me it was one of the best dental she’s been too. Last dental I was in were rude and kept me waiting for ever ! And by the end of the day they would tell me they couldn’t see me. Which was awful. Nu Smile Dental is one the best I knew I was in good hands once I walked in. Dr. Moeinolmolki is awesome and funny she makes you enjoy the dentist. I recommend all my coworkers and family members here ! This is some where you will enjoy I sure do ! 😀

I had a wonderful experience taking my children for their dental care to Dr. S. Moeinolmolki.  She is patient and great with the kids, able to make them feel comfortable and at ease prior to performing her dental procedures.  I had a relatively short waiting time and was pleased with the office staff and their professional behavior.   Dr. Moeinolmolki is an excellent dentist and I would recommend her to all my friends and family.

I cannot say enough about the work Dr Sepideh and her staff do. I moved to California from across he country and was extremely nervous about finding a new dentist that I trusted to be knowledgeable, have he latest technology, and trustworthy. After multiple visits for cleaning and a couple cavities, I was interested in closing some gaps in my front teeth. Dr Sepideh and her staff took the time to walk me through every possible solution- time tables- and pricing for anything from retainers to Invisalign to veneers. After deciding on composite veneers (done in one hour!) I was SO HAPPY with the results. As a master of her craft and an artist by nature I would recommend this office for any sort of cosmetic dental work. Fantastic experience overall ! Highly Recommend !

Janice K. form Newport Beach, CA (Source: Yelp)


This is by far the best dental practice. Have no fear of “the dentist” anymore. As a matter of fact, I look forward to seeing the friendly staff. My gums have been healthy since I found Dr. Moeinolmolki and I wouldn’t chance it going to any other dentist.

All my life going dentist made me nervous beyond belief but they have found a way to make me feel comfortable. I have been going to this dentist for a few years and now it feels like I am visiting my friends when I visit and I look forward to it!

She is an incredible doctor. Highly skilled and very artistic. She speaks each situation in an easy way to understand for someone like me who is uneducated in the field.

Taylor C. from Costa Mesa, CA (Source: Yelp)


Dr. Moeinolmolki is an amazing dentist. I had spaces in my teeth from taking of braces to early and hated that me teeth were so pointy. Dr. Moeinolmolki shaved them down and filled in the gaps. My teeth look amazing I didn’t have my teeth cleaned at the time but ever since I got the work done every one has been commenting on the whiteness of my teeth! My confidence has boosted and I feel like smiling in pictures (which is a first) Thank you to you and your team Dr.Moe!!

Dr. Sepideh is professional, skilled, and speedily proficient.  This is especially helpful for things on the more unpleasant side, like unexpected fillings (my first visit here).  She is certainly the best dentist I’ve ever had, and I haven’t had any real dental issues since she took custody of my dental health.  I have been coming here since I changed jobs in 2007 and found them using my insurance plan (which they happily take). They use digital x-rays (quick), have TVs in the dental rooms, and I’ve never had to wait more than 5 minutes in the pleasant lobby.  The rest of the staff is friendly and courteous, and I certainly will be staying with this dentist as long as possible.  I’ve had several dental assistants do the cleanings over the years, but they were all fine and I always saw Dr. Sepideh each visit for a careful review.  She also remembers me well even though I’m only in every 6 months, and that adds to the friendly atmosphere since it’s obvious she values her patients. My favorite experience was that I once had a small spot cavity between two contacts, but instead of reprimands or accusatory questions about my dental hygiene, I was told that it’s OK, even dentists get cavities too sometimes.  No uncomfortable guilt trips here!

Summer M. from Santa Ana, CA (Source: Yelp)


The BEST dentist I’ve found so far.  Dr. Moeinolmoloki and her staff were amazing!!  From the front off to the back everyone was professional and friendly.  My daughter keeps saying “This side is shampoo and this side is conditioner.”  I loved them so much I decided to make an appointment for myself and ditch my current dentist.  Everyone at this office is so personable.  Really made an impression on me.

Tonya K. from Ripon, CA (Source: Yelp)


I have been with this dentist for about 2 years since they performed a root canal soon after I gave birth to my son.  I am an adult who has a very small jaw and needs to have a combination of adult and child-sized tools/equipment in order to get even routine x-rays done.  Dr. Moeinolmoloki and her staff have been awesome on both followup and regular visits.  After procrastinating on a cracked crown for nearly 6 months, Dr. Moeinolmoloki replaced the crown for FREE even though it was my fault for not having gone in sooner and would have otherwise needed to pay for a new crown in any other dentist’s office.  I have complained once or twice of pain since they don’t always remember to use child sized equipment on me, but changes are promptly made when I speak up and say something.  I also experience no pressure when it comes to getting things like whitening and Invisalign (two things I have been wanting to do for over 4 years now).  I am reminded of the benefits and discounts I can receive based on current promotions they have, but am NEVER pressured to buy anything.  I think they know that I’m the type who will do things when I am perfectly ready and willing.  Anyhow, I have plenty of dentist’s offices closer to home or work, but seriously, the service and quality of care here keep me coming back.
