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

I whole-heartedly recommend Dr. Shireen – I’ve been a patient since 2012 and I will never need to look for another dentist again!

Sitting in the waiting room feels like visiting a spa. From the music to the comfy sofa and chairs, visiting Dr. Shireen is the most relaxing dental experience I’ve ever encountered. An added bonus: there are always plenty of great magazines to choose from if I arrive a bit early.

When I am in the chair, Dr. Shireen and her warm, friendly and amazingly talented staff make my visits a calm, soothing and enjoyable (gasp!) experience – from cleanings to fillings. Dr. Shireen is incredibly gentle with her drill, she continually checks in to be sure that I’m doing all right. Not only is she diligent about numbing my sensitive mouth, she keeps track of which teeth need a little extra love and will make extra sure I’m numb before she starts working. That’s just one of the extra service details that make me a happy, loyal client for life.

I love these guys!!!!!
I have had two dentists over the last five years that I hated. I always felt they were pushing me to do unnecessary work and never felt comfortable with them. I spent a long time researching dentists and found Dr. Shireen through Yelp. I was a little suspicious with every review being five stars but I decided to give them a try. After 4 appointments, I now see why they have such high reviews on Yelp. I love the office staff. They treat you like a friend from the first time you walk in the office. When it came time to have a filling, they were so gentle I did not have any discomfort at all. In fact when they gave me a shot of Novocaine, I was not sure if they were giving me a shot or not. That’s how gentle they were.  I love these guys!!!! I have now found a dentist that I will keep for life. Dr. Shireen is awesome. She makes you feel like she really cares and the staff really makes you feel at home. This may sound weird but I now enjoy going to the dentist. I would especially like to thank everyone in the office and give them my highest rating!!!!!!!!! I would give them six stars if I could.

Seriously, i love my dentist… words i have never said before!!

if you’re looking for the most professional, kind, friendly, honest and gentle dentist, look no further.  dr. shireen just did a thorough exam of my teeth and gave me the facts.  she showed me the areas of concern in easy to understand terms and photos, and made my decision to proceed with her recommendations easy.  

i had teeth cleaning done today and i feel great. i was squeezing the arm rest in anticipation of pain and misery, but before i knew it, i wasn’t even feeling anything. she knows how to do her work while keeping the patient’s comfort in mind.  i walked out of her office thinking “hey, you know… i could get used to going to the dentist more often!”

highly recommend dr. shireen.

Gentlest most professional group ever. Dr. Shireen knows her stuff.

C. B. from Laguna Beach, CA (Source: Yelp)


I’m scared to death of going to the dentist – start worrying about it the night before and usually have myself worked into a frenzy by the time I walk in their door.  But  Dr. Shireen and her staff are great – not only do they do top notch dental work but they have real compassion for my deep rooted fears and do whatever it takes to get me through the appointment with the least stress.  It’s a good place to go for a visit none of us particularly looks forward to.  I would recommend this dental office without hesitation.

Matt H. from Orange, CA (Source: Yelp)


I’ve been coming here for 4 years now, Dr Shireen and staff are incredible. I had a veneer placed on my front tooth and it looks very natural. The dental hygienist really knows her stuff and I always come away feeling like I got a great cleaning.  I always recommend my family and friends to Dr Shireen!

Lani B. from Newport Beach, CA (Source: Yelp)


Absolutely love this place. I just came in for a cleaning. The staff was professional and the doctor was very knowledgeable. They are the most caring dental team I have ever worked with! I would highly recommend their services to anyone.

Brianna M. from Westminster, CA (Source: Yelp)


This review is long overdue! I love the entire team! I am always greeted with a sincere hello and the waiting room smells like apple cinnamon…truly a warm welcome 🙂

I actually look forward to my appointments! I know, sounds crazy but it’s true!
I have never ever felt judged for waiting so long to get back on schedule for cleaning etc. That is probably why I always feel so comfortable there.

They are really good about calling you right away if there is an opening due to a cancellation. I take advantage of this because sometimes they are booked for awhile (probably because they are so amazing!).

Dr Shireen and her entire team are great! I have been seeing them for over 5 years now and am so much happier than I was with my previous dentist.

West N. from Myrtle Beach, SC (Source: Yelp)


I made an appointment after reading the reviews on Yelp and was not disappointed.  Dr. Shireen and her staff are top notch!  Through the entire process they explained everything that was happening in ways I could understand and were very comforting.

It had been a very long time since I’ve been to a dentist but the only concern of everyone in the office was getting me back on track.

Andy P. from Santa Ana, CA (Source: Yelp)


Dr. Shireen offers quick, efficient service while also providing an excellent staff that makes you feel at home every visit. I’ve gone for routine cleanings and always leave with a clean fresh smile.

Sheri T. from Costa Mesa, CA (Source: Yelp)


This is the best dental office I have ever been to. My 18 year old daughter has been a patient here for about a year now. Kathleen who works the front desk is very nice, efficient, and she will go out of her way to help you with insurance and payment arrangements. Dr. Shireen is very pleasant and will discuss every matter with you before starting treatment.. The Dr. explains exactly what is going on with your teeth as she goes over the x-rays in detail for you. The atmosphere is very calm and casual. The office smells really nice and has soothing waterfalls.I would recommend this office for my family and friends or to anyone looking for a positive dental office experience. We are very happy and satisfied.

If there were MORE STARS I would ADD them!
the SIMPLE “Woohoo! As good as it gets!” is nothing!
They are SUPERB and are far beyond AWESOME at what they do!
The services at her place is far beyond words can explain!

Dr. Shireen and her staff are the BEST! I was EXTREMELY scared and feared by just the thought about having to see a dentist due to some previous bad experiences!
Dr. Shireen and her staff changed that!

Since the day I met her I was sure I was in good hands! She is absolutely the BEST at what she does! Words cannot explain the comfort and ease that she makes you feel, it is absolutely wonderful. Her staff as well is GREAT! They are the most professional ladies you can meet! GREAT JOB LADIES & and God Bless!

Lisa M. from Newport Beach, CA (Source: Yelp)


Something I never thought I would say: I love my dentist! Dr. Shireen is great, I’m so glad I found her. Everyone in the office is very nice and they do a great job of making you feel comfortable. I have already referred a couple people and I would do it again and again!

Jessica S. from Mission Viejo, CA (Source: Yelp)


I’ve been going here for about two years and Dr. Shireen and her staff are such great people! Always so welcoming. Recently I had an accident and got my chipped tooth and Dr. Shireen immediately was able to assist. Her work is amazing and I can’t thank her enough for helping me get back my perfect smile.

Miss J. from Newport Beach, CA (Source: Yelp)


Wonderful! Wonderful! Wonderful! Great staff, great customer service. They make going to the dentist not as scary as it really is! I have been a patient for a few years and would highly recommend Dr Shireen and her staff! They are amazing. Thanks ladies for all your hard work!

I am very loyal to my doctors and dentist and switched to Dr. Shireen a few years ago. I am so glad I made the switch. Not only is her office beautiful and peaceful, but the entire office staff is extremely friendly, knowledgeable, willing to help and go the extra mile. Most importantly, though, is the fact that I haven’t had to go back to have a procedure “fixed”. Dr. Shireen gets it right the FIRST time. Cleanings are easy and not painful but I’ve had two major procedures in her office recently that were executed to perfection which meant no additional visits. If you’re afraid of the dentist or have had work done improperly, I highly recommend you visit Dr. Shireen. You will be happy you made the switch!

Charlene J. from Santa Ana, CA (Source: Yelp)


My BIGGEST, BIGGEST fear is going to the dentist.  I rather get tattoos all over my body than go to the dentist. In the past 10 years I have gone to the dentist 3 times, I initially went to (a different dentist), but HATE THEM!!  I had 1 dentist for 18 years of my life, I am much more used to going to one office where there is one dentist working on you.   I needed 2 root canals desperately and my face gotten swollen and I found Dr. Shireen online and was right down the street from me and was able to squeeze me in that same day!!!  

Dr Shireen, Cat and Heidi were ALL so very encouraging, generous, reassuring, and so much more than I can say.  I, actually after 30 years, now don’t mind going to the dentist at all anymore!  They definitely feel empathy for you and make you as comfortable as possible!  I love them!

Tony S. from Santa Ana, CA (Source: Yelp)


They are number 1 for a reason. I came to them after having a toothache for days and was hoping it would get better by itself but it became worse. Anyway I’ve had bad experiences with dentist and was extremely nervous about getting a anesthetized and having a drill in my mouth. I explained to Dr. Shireen about my past experiences and she was very concerned and caring. They made me feel very comfortable and when i got anesthetized it was the best experience ever. I did not feel a thing and she was able to perform a root canal same day. Now I look forward to my next visit, Oh and the staff was great. I would highly recommend Dr. Shireen to anyone and everyone,  you won’t regret it.
Thanks, Dr. Shireen, Heidi and Cathleen.

Veronica Q. from Banning, CA (Source: Yelp)


I’ve been with Shireen Dejbakhsh for almost 7 years now, and I love her and her staff, they have taken very good care of me and my family. They are very caring and understanding.  My kids enjoy visiting the dentist thanks to her. Also whenever you need to see an specialist she will refer you only with the best. You cannot go wrong with her.
We drive from Riverside and it is worth it.

Thank you Dr. Shireen, Heidi, Lorena for taking great care of my teeth. Your bedside manner is gentle, kind and makes any dental procedure much more bearable. Thank you times a million and cheers (…).

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


Dr. Shireen and her staff are all incredibly friendly and helpful. I am incredibly glad to have found a dentist that I can trust and feel confident about.

Nikki F. from Irvine, CA (Source: Yelp)


I’ve always been terrified of going to the dentist but Dr. Shireen and her team make it a wonderful experience. The quality of her work is outstanding and the pricing is fair. I would recommend her to anyone.

Marissa M. from Fullerton, CA (Source: Yelp)


Dr. Shireen is awesome!  She was able to squeeze me in for a few appointments to get rid of a black stain on my front tooth from a previous dentist right before my wedding!  Her and her team were so flexible when it came to finding appointments to work with my crazy schedule all so that my teeth would be perfect for my wedding day!!  I highly recommend Dr. Shireen!

Noel A. from San Francisco, CA (Source: Yelp)


Dr. Shireen and her staff are awesome. I’m so happy I found her on (the internet)!

It’s been two years since my last cleaning/exam — been putting it off because I’ve had some bad experiences so when I read the reviews she sounded like exactly what I was looking for in a dentist.

Dr. Shireen was very gentle, kind, and best of all a true – honest – professional.  (The same can be said for her assistants who were all very sweet as well.)

I had an amazing pediatric dentist , whom I saw until I was 24, but since then I have literally gone through about 6 dentists which culminated in one of the most horrific dental experiences I’ve had to date. Thus, I’ve been dreading making an appointment ever since. It wasn’t until I was an adult that I “feared” my dentist so it’s so refreshing to know that I can get back into a 2X year routine without dread.

Highly recommend!

Qyna T. from Costa Mesa, CA (Source: Yelp)


Awesome service every time I walk in. Dr. Shireen and her team are very nice and helpful. I even got a blanket and view of the sunset while I was getting my fillings done! Always feel comfortable, welcomed and always leaving with great work on my teeth!

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


I used to be terrified of going to the dentist, then I found Dr. Shireen and her team. The ladies in her office are very sweet and helpful, Dr. Shireen greets you by name and makes sure you are happy with her work. She did a root canal on me and it was painless. Love this place!!! I wish I could give them more stars.

Brandon J. from Huntington Beach, CA (Source: Yelp)


Dr. Shireen and her team are the most amazing people. I have been going there for the past 3 years and each experience blows me away. Going to the dentist has never been anything I want to do, however she makes you feel so welcome. They take care of me like I am there only patient. I would recommend Shireen to anyone. I had to have emergency dental work as my filling fell out. I called her and she got me in the next day and fixed my problem in about 1 hour. I couldn’t be more grateful to her and Heidi. Thank you for everything you do Dr. Shireen!

Dr. Shireen is an amazing professional, she and her staff are the best in providing the information and service one would hope to have at the dentist.

Mark B. from Newport Beach, CA (Source: Yelp)


Let’s be honest, who really likes going to the dentist?  I hate it.  But, this is a great dental practice.  Dr. Shireen and her team are very personable and professional; they really go “the extra mile” to make everyone feel comfortable!  The office is a very nice, calming environment.  She gives patients without dental insurance a cash discount, which is reasonable and fair!  I highly recommend Dr. Shireen!

Jessica A. from Irvine, CA (Source: Yelp)


Dr. Shireen is so nice with excellent bedside manner. She seems to be very thoughtful and considerate with her patients. Of course no one prefers going to the dentist, but her, the dental assistants and front desk staff are all lovely and make it okay. The office is also very cute and clean. I’ve been here a few times now, and everyone always goes above and beyond to make sure I am comfortable and well taken care of.

Thank you so much for my Zoom teeth whitening appointment today! I’m soooooo happy with my results! You and all your staff are all so very nice!!!

Tracey V. from Costa Mesa, CA (Source: Yelp)


I LOVE Dr. Shireen and staff! I have been seeing her for about 5 years now. I have only had 3 dentists in my life: the one I went to growing up until I was about 23, the one who gave me an emergency crown when I had no insurance, and then Dr Shireen, who patiently cleaned up years of dental neglect. I’m not quite sure she knew what she was getting in a patient when I first walked through her door joking that the only reason my teeth were still in tact, “was because the tartar was holding them together!”

For me, going to the dentist has always felt like going to confession. “No, I haven’t been flossing; I know soda is bad, but…; I got the Sonicare that you recommended, but I haven’t been using it.” Dr Shireen will always reiterate what best practices are, but I have never felt guilty or anxious that I’ve been slacking. In fact, she makes me WANT to be a better dental patient. In fact, she normally only puts her younger patients on her Facebook ‘No Cavities’ Wall, but better believe when I finally had a cavity free check-up she willingly put me up on that wall too!  

There’s not much more that I can say about Dr Shireen and her staff except I truly look forward to when I get to escape work for a bit and visit people I consider friends…who just so happen to give me a beautiful smile while we’re catching up.

I’ve had to change dentist since my dental office was just not cutting it and plus them moving a lot further from me- as I was on my search for a new dentist. I decided to go with Dr Shireen after reading all the reviews and all that they had to say. She and her staff are stellar and have not disappointed me one bit. They’re courteous and efficient in their dental game. Try them out, you will not regret it. My teeth are always on point and am so grateful for Dr. Shireen and her amazing attentive staff.
Thank You Dr. Shireen and your amazing staff for making me feel right at home and not in pain each time I go in.

I drive from Los Angeles and back because Dr. Shireen is that great at taking care of me. She is the first dentist who ever listened to me and she adjusted to my fears of dentistry until I was comfortable. Now I look forward to my visits with Dr. Shireen, Heidi, and Kathlene. She is so patient and caring that I finally learned to follow what she kept advising me to do with daily habits and my teeth have NEVER been more healthy. Dr. Shireen really does want what is best for me and my teeth.
