Best dentist I have been to thus far!
I have always been turned off by feeling pressure of being pushed into extra treatments and unwelcoming personalities and/or staff that just rushes through the process, but at Sunshine Smiles you feel so welcomed and they treat you as if you are family. I highly recommend this dentist to people of all ages. I also recently got my cleaning and impressions for whitening trays done and they had my trays ready in just two days! I am so happy with the outcome and look forward to my future dental experiences with Sunshine Smiles. My husband just had to get a root canal and they worked him in the last minute to fix it so he was no longer in pain.

This is a family-owned practice, mother, son & daughter-n-law and they treat their patients like family!!!  They care about their patients and they care about their work.  I have had everything from the basic cleaning, to bonding a chipped tooth and a crown and I have been extremely happy with all my dental work and the care I received.  If anything comes up, they are quick to get you in….no waiting a week or so.  You will love this family and the beautiful teeth they give you!!!!  Go to see them… will love them!!!!

One of the best dental offices I’ve ever been to! They take such great care of you here! I had cosmetic bonding done to my teeth and they are absolutely perfect! Not only do they take care of your needs/ teeth, but they have great payment plan options. Couldn’t have picked a better dental office!

I have only ever had the greatest experiences with all the dentists and staff at sunshine smiles. From helping me with last minute appointments to check on a concerned toothache to following up with me after having my wisdom teeth removed, just to make sure everything is okay, there is a reason I drive over an hour to come to this dentist. It’s worth every minute.

This was my first appointment here and I had a fantastic experience. The staff was friendly and everything looked clean and new. Having the option to watch Netflix during the cleaning/exam was great, especially for those who get nervous at the dentist. Dr. Arshia Kalantari was kind, personable, and very thorough. I felt that he was truly interested in my dental health and not in trying to sell me on a procedure.

We were very pleased with the facility, people and their sincerity willingness to go out of their way to make us feel comfortable with their methods and practice. When we left we felt we knew them and had been with them for years. The honesty in which they talked about our needs and the time taken to go over how they work and would work with us was very refreshing. You could tell they are about the patient and what is best for us and not about the money.

Al S. from Irvine, CA (Source: Yelp)


WOW talk about a new and refreshing dental experience, no pun intended. Amazing service from the staff and I must say, being able to watch tv with headphones while they clean my teeth was a great experience. First time and I can’t wait to go back. Great work, Dr. Kalantari. 🙂

I could not be happier with the care I’ve received from Dr. Kalantari. He explains everything he proposes for my dental care in such a detailed way that I know exactly what’s going on with my teeth. I then have 100% confidence in the procedures that we decide together to perform. He is also very careful & gentle.

Phong L. from Tustin, CA (Source: Yelp)


I thought I had a cavity for the longest time. I went to my regular dentist but they didn’t see anything on their x-ray. Months went by and was still having aches but one night it was extremely painful. My jaw was now hurting and my ear was ringing. I went in to see Dr. Arshia that morning. He took x-rays and found out that I had a couple cavities and one needed a root canal. Just finished up my root canal and just waiting on the final crown. The procedure was nice and smooth and painless as possible for a root canal (…). Super friendly and total professionals. Much appreciated.

Sunshine Smiles of Orange County provides excellent dental care in a beautiful office. They are very friendly and really care for their patients and help them maintain healthy teeth and gums.

The dentists and staff are all incredibly nice and they do excellent work. My husband and I have been coming here for about 2 years and we have been very happy with all the services we have received.

My whole family has been going to Sunshine Smiles for a couple of years now! It’s family-owned, and they make you feel like family! The doctors are honest and kind.

Ena K. from Irvine, CA (Source: Yelp)


This is the best dentist experience I’ve ever had. The staff is friendly and extremely knowledgeable; my exam and cleaning was painless and fast. There were no pushy sales for extra unnecessary procedures. I actually enjoyed my visit and highly recommend this office to anyone in Orange County!

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


I definitely recommend this dentist and here’s why: Front office staff are nice and efficient. Office is clean, modern and comfortable. Hygienist is very polite and kind. The dentist genuinely cares about your smile and wellbeing.
I left feeling well informed and not like someone had just pressured me into additional treatments like my previous dentist.

Faith Hommes (Source: Google)


I give my highest recommendation of Sunshine Smiles. This was my first time as a patient coming in for a cleaning. I felt so welcomed by all the staff and doctors. They are an amazing family that genuinely cares to get to know you. My cleaning was at 5 pm and I mentioned an interest in Invisalign. Instead of making me come back, they all stayed until 7 pm to help me get started with Invisalign. I can’t wait to continue my treatment at Sunshine Smiles!!

Great Dentist! My wife had some bridges installed next to her front teeth, and the look afterward was AMAZING. There was a complication related to her new bite that was causing a lot of sensitivity, but after consulting with our dentist, a follow-up appointment was immediately scheduled and the bite was corrected. We will definitely continue to come here for all cleanings and any future dental work.

Forrest Wiederman (Source: Google)


(Partner dentist), Dr. Kalantari and their staff are amazing!! The comprehensive approach they take to Dentistry makes it easy to get everything done. My experience from the moment I stepped into the time I left with a clean healthy smile was the best I’ve had at a dentist. I will forever be a life long patient and trust the office with whatever they recommend for my dental needs! Thank you so much for giving me more confidence with my smile and making the experience comfortable and easy!

(…) Their office consists of state-of-the-art equipment, techniques AND staff. The care with which they treat their patients is world-class. I appreciate their professionalism, kindness and concern. (Partner dentist) and Dr. Kalantari have created something we don’t see very often these days. Personalized, gentle and excellent care. And every single person on staff is phenomenal! Taylor, Mina and Lauren…wonderful ladies! Again, such kindness and helpfulness. I think I can honestly say I look forward to going to MY dentists now!

This new office in Mission Viejo, CA has a beautiful atmosphere, friendly staff and great dentist to address your family dental needs. I met Dr. Arshia Kalantari to consult with him about what bothered me the most about my smile, he listened to me patiently and told me with the latest techniques he can solve the problem for me. He worked on my front lower teeth for over 2 hours, I did not feel any pain, he constantly checked with me on how I feel and if I am comfortable. The end result was amazing and I now love to smile even bigger. Thank you Dr. Arshia Kalantari.
I highly recommend this office and their dentist.

Great office, very welcoming. The front office is so helpful with those pesky insurance questions and it is clear that this is a family practice that truly cares. Great kids area and chairs that make that first scary dental experience so much easier. Would not hesitate to recommend.

I have been here for 3 crowns and all the other visits that came with those and a cleaning, and every time I come in I feel like I’m visiting family. Very happy with sunshine smiles, from staff to assistants and dentists. Friendly, clean honest and classy all the way, one of the best dentistry businesses I’ve ever been to. Don’t mind when I have to go in!

Miguel Ruiz (Source: Google)


Every time I visit I’m welcomed by the awesome staff. I will not go anywhere else, the work is always perfect and precise. I wouldn’t trust anyone else with my smile. I’m happy with my Invisalign.

Farah AlAttar (Source: Google)


The whole team is amazing. The kids just love to go there. Everybody is so kind and know how to deal with children. Thank you sunshine smiles for a great experience!

Sierra Garcia (Source: Google)


I’m honestly terrified of the dentist and they are amazing! They made the experience very relaxing and one of the nicest dentist I’ve ever been to. They truly care about helping you and fixing your dental needs! I have found my forever dentist!

Dr. Joseph D. from San Diego, CA (Source: Yelp)


This is a really great office, very friendly and professional, and excellent skills!  There is no hard sales, seams like other offices I have found that is not always the case.  Can’t say enough good about them.

Claudia G. from Mission Viejo, CA (Source: Yelp)


Such an amazing dentistry! Got two root canals done today and I can’t express how happy I am that I found such an amazing dental office. Such caring dentists and staff. From beginning to the end they were all so attentive and patient with me as I get very nervous and anxious during procedures. Dr. Kalantari was very gentle and attentive. He continued to ensure I was comfortable and pain-free throughout my procedures (…).
Thank you all very much!!!

The whole team was super friendly and they got me in and out quickly and did amazing work. Highly recommend sunshine smiles of Orange County.

Bruce Porfilio (Source: Google)


Never having had major dental work done before I was anxious and fearful. I was fortunate enough to be treated and cared for by the compassionate and intelligent staff at Sunshine Smiles of Orange County. Their patience, empathy, and sensitivity are remarkable. Before, during, and after my extensive work, I was cared for with exquisite personal attention. During the work, they did everything possible to mitigate physical pain and mental-emotional anxiety. They are excellent communicators who explain options masterfully. I never felt coerced or rushed to make any decisions. I give them my highest recommendation.

Haroon A. from Laguna Hills, CA (Source: Yelp)


Where do I even begin!? Sunshine Smiles of Orange County really changed my attitude towards visiting the dentist. As soon as I entered, the staff was so friendly and inviting that I found myself excited to be there! Not to mention, (partner dentist) and Dr. Kalantari are some of the most down to earth doctors I’ve ever met. I highly recommend visiting this office, as their work is amazing as well.

B. S. from Laguna Woods, CA (Source: Yelp)


Going to the dentist is NOT my favorite place to spend time, but I had my first visit at Sunshine Smiles of Orange County for X-rays and cleaning today and was so comfortable.  The office is new and beautiful, the staff is so friendly and  I actually enjoyed my cleaning!  I highly recommend this dental office.  Best dental experience I’ve ever had.

Haleigh W. from Tempe, AZ (Source: Yelp)


After having a bad experience at my previous dental office I was recommended to them and I am more than happy with my decision to switch. Jessica and Taylor at the front desk are so nice and welcoming and Jessica even called my insurance for me when I forgot to reassign dentist offices. Sunshine Smiles is family owned and they all genuinely care about you and providing the best care. They don’t try and up-sell you services you don’t need like my last dentist did. The whole experience was enjoyable and they even offer free whitening trays and gel with your first cleaning! 10/10 recommend Sunshine Smiles!

Brent Pickelsimer (Source: Google)


Absolutely painless visit! Dr. Kalantari is more than just a great Dentist, he is an extremely knowledgeable Doctor who understands the medical aspects of dentistry that interrelate with, and impact on, one’s overall health and wellness. He has a great bedside manner in that he can explain complicated medical terms in plain English. He gives straight forward treatment advice and does not “upsell” procedures that can be safely delayed until one can afford them. I loved the Big Screen tv ON THE CEILING because I caught up on my favorite Netflix show while my teeth were worked on!!

If you’re looking for a trustworthy, friendly, extremely skilled team of professionals then you must come here! I have a big fear of going to the dentist, but after my first visit, I immediately felt at ease and am looking forward to fixing the dental work I’ve been putting off. You feel like part of the family! The office is very clean and inviting, and as soon as you walk in you know you’re in good hands. I’ve been looking for a family dental practice for a long time, and very glad to have found it. Very happy with my experience!

Jake Futral (Source: Google)


Absolutely fantastic and I mean it wholeheartedly, I have never been one to go to the dentist unless I’m in unbearable pain but the team at Sunshine Smiles was so nice and friendly that I have no problem going in for check-ups and cleanings. They are truly the best.
