SIMPLY THE BEST YOU WILL EVER FIND!!! Dr. Zadeh absolutely excels in dentistry and her cosmetic dentistry skills are beyond par! My front tooth had begun to show a growing black spot - not only was she able to diagnose and treat the tooth, she was able to correct it and match the shape and color to PERFECTION! Truly an artist!

Dr Nina and her team are an absolute 10/10. I have a number of dental issues to address and she's pacing out a treatment plan that considers the urgency of care needed with the cost associated. She humanizes this experience well beyond it being a mere transaction. Excellent dental care begins with trust and I look forward to perpetuating this relationship. Gratitude! read more

I always dreaded going to the dentist until I found Dana Cosmo Dental (south county's best kept secret). Finally, a dental care group that prioritizes giving its patients the best care possible, instead of just making a profit. Dr. Nina Zadeh is a vetted expert in her field and is without a doubt the best of the best in Orange County! The staff at Dana Cosmo Dental never fails to go above and beyond for each patient, and they are as friendly as it gets when it comes to customer service. It never feels like a real trip to the dentist because they treat you like family here. I cannot recommend this place enough to anyone in OC looking for a superior dental care provider. BEST DENTIST EVER. read more

Unfortunately our experience here was not good. It's been a few years and I was frustrated so decided to wait on leaving a review. We had issues with billing that we never have had before or after with another dentist. My husband had a number of issues with the work that was done and went back because the crown wasn't seated correctly and continued to cause discomfort for months. We have since moved and today my husband went back to his prior dentist to find out that there was still a gap and that had caused infection and erosion under the crown that is now so severe that he will have to have an implant so I thought it was worth leaving a review since I chose that dentist based on Yelp reviews and can not recommend this dental office at this point. read more

I went in for a consult and Dr. Nina was so amazing. She was kind, compassionate, caring, and I wish I had known her from the first day I started going to a dentist. I will definitely be coming back to her for all my dental services. I highly recommend you visit her office and use her for your dental needs. read more

After 3 pregnancies and a chipped / discolored tooth, I went to Dr Nina for a quote on veneers - and she was the only dentist out of the 3 that I visited that really pushed for a far less expensive treatment of whitening / bonding.... She was able to give me back my smile and somehow make my teeth look straighter in about 1.5 hours. Thank you Dr Nina! Oh and she's a Bruin which doesn't hurt either! read more

DR NINA ZADEH IS THE BEST BEST BEST DENTIST I HAVE EVER HAD A CHANCE TO WORK WITH. I have had best rated "celebrity dentists" from Croatia, Switzerland, Nevada and California doing my Teeth. No one can compare with Dr Nina. Not only her staff is the friendliest and sweetest people to be surrounded with; but doctor Nina is truly the best in her industry. Highly professional with all newest dental gadgets you can imagine!!! If you are considering or comparing Dr Nina with other dentists - please give her a chance you will be satisfied more than you can imagine. She is extremely flexible; works fast and treats you and your teeth the same way she would've done it for herself or for her kids. She doesn't overcharge/ she is very fair with pricing.

Dr. Zadeh is an artist as much as a dentist. I had some old veneers and some bonding that was in desperate need of replacement and repair. She took the time to assess the situation and come up with a cost effective and aesthetic approach. I couldn't be happier with the results. My front set of teeth haven't looked this good in 20+ years. I am switching to Dr. Zadeh for ALL my dental care after this. read more

Dr. Nina Zadeh saved my vacation! While visiting California, my front veneer popped off. The thought of spending 2 weeks touring the state with a missing front tooth horrified me. When I called her office, I was seen within the hour. Her staff was warm and friendly. Dr. Zadeh assessed the situation and quickly put my veneer back in place. It was totally pain-free. Highly recommend Dana Cosmo Dental. Aloha~ C. Pierce read more

To Whom it may concern, Dana Cosmo Dental is a "Hidden Gem" any Dr. Nina is outstanding, quick and efficient. Everyone in the office is very kind, patient and understanding to customers needs. They have the latest technology, and I really value the laser to maintain healthy gums. I am typically scared to go the dentist and now I truly enjoy making sure I am taking great care of my teeth. With Dr. Nina's excellent advice and important suggestions to maintain the best health I couldn't be in better hands. I am very grateful, Thanks, Liero read more

Best experience I could have had at the dentist today as I always do at Dana Cosmo Dental. Specially considering the fact that we are in the midst of the COVID-19 pandemic, I am sure everyone is anxious to go to the dentist, as was I. But the level of expertise on following the infection control Guidelines was beyond clean, sanitary and precise which made the experience that much better. I was so happy to see my amazing dentist who treats all her patients like family. My visit was an emergency as I chipped my front tooth. She made it not only look good, but even better than it was before the chip. She is so good at her cosmetic procedures. Thank you Dr. Nina!!!!! read more

Amazing dental service and everyone in the office was so kind. I can't recommend this dental office more highly!!! Mahsa was fantastic and went above and beyond with my cleaning. She was so thorough and saved me from needing a much more extensive procedure that other offices we're recommending (probably because it's more expensive). Dr. Nina is the best! She is so welcoming and gave me the same care and attention I imagine she would give to a family member. One of the best dentist I've been to from a technical point of view too! Molly, the dental assistant, was so good too! I've seen a lot of dental assistants in my life and Molly was by far the best! Plus she's hilarious! Lol read more

Dr. Zadeh and her husband go above and beyond for their patients. I have lived in the area for 30 years and believe this to be the most caring and ethical Dentist office in South Orange County. All of the staff are very courteous and professional and the Dr. is exceptional. read more

CHARGED $2100 FOR A DEEP CLEANING AND XRAYS - this is WAY more than they should ever be charging!! My husband and i went to them for several years, because they are so close to our house (this is the only reason). However, when covid hit i didn't go to the dentist because both myself and my new baby were high risk the first year. By the time i went in, it had been about a year and a half since my last visit. They made a cleaning appointment for me knowing this. During that appointment I had to sit there for an hour and a half while the dentist tried to talk me into doing a deep cleaning & gum laster treatments. The only thing she was willing to do during this visit was take xrays. She told me a story about her sister's gum issues, which she stated i did NOT have, but that it could happen. She was quite aggressively trying to upsell me. I said I wasn't willing to do any of that and just wanted her to do the cleaning I was there for. She completely refused to do the cleaning, and forced me to come back for a deep cleaning with her tech/nurse. There was also no mention of any cavities when she looked at my xray. I then come in for the deep cleaning, because she refused to do the standard cleaning, and that meant two separate visits. The deep cleaning took less time than the past visit where she refused to do anything for me!!! I was also informed my wisdom tooth had a cavity. How did the actual dentist not see this?!?! Of course the nurse made an excuse for her, but that is ridiculous. They were not willing to fill the cavity, because they wanted me to go to a specialist to have it pulled since it was a wisdom tooth (not a big deal). However, once i got the bill for just a deep cleaning and one set of xrays they charged $2,100 for these services!! All dental coverage caps out at $1,500, which they would have known before doing any of this work, and never informed me of these crazy fees!!! I called to ask them how they could do this, and they said that they were shocked the insurance company was willing to pay out the full $1,500 and didn't negotiate the fees back at them. They basically admitted they overcharged insurance, assuming they would have to go back and fourth negotiating fees with them. Now, because of this, I had to pay out of pocket (almost $2,000) for my wisdom teeth to be removed. I have since found out that a deep cleaning should only cost around $300.00 they charged over a thousand. Now I was unable to do any additional cleanings for the year. Not only that i had to pay out of pocket for secondary dental insurance, for the wisdom teeth, and still paid additional out of pocket expenses. I will NEVER go to them again! read more

The Dentist is awesome and everyone at the office is extremely professional and nice. The Hygienist was excellent!

Dr. Zadeh saved my vacation! I had an emergency with one of my veneers and they fit me in right away, did the work fast and perfectly, and I was on my way. And everyone in the office was so nice and accommodating. Even though I live in LA I will be driving down to this office for all of my future dental needs. I seriously would give Dana Cosmo Dental 10 starts if I could! read more

I'm writing this as a person who does not normally enjoy going to the dentist, nor do I go as often as I should. My experience at Dana Cosmo was exceptional. Dr Nina is a delight and the rest of the staff was very kind and couldn't have been nicer. If you need a new dentist (or have been avoiding the dentist, like me), make an appointment! I've already set my next one up. read more

Dr. Nina Zadeh is a kind, intelligent, and highly competent dentist. She does an amazing job working on my teeth and doing preventative checks as well. Dr. Zadeh truly cares about her patients. Her dental hygienists are very efficient with cleaning my teeth and removing tartar effectively. The office is always accommodating and able to schedule me in a timely manner for my regular teeth cleaning. All the employees are nice. I highly recommend her as your dentist. read more

Simply the best!!! Nina is a magician !!! Very clean facility with friendly personnel. I highly recommend Dana Cosmo Dental!!!

I got a referral to come here and I am glad I did. The entire staff was super friendly. I had a teeth cleaning only. It wasn't too painful. That hopefully means they did a good job being gentle! :) Only time will tell! They took pictures of my teeth, too. Perhaps that is a good way to keep track of the condition of my teeth but I haven't had that done before. I've only been there once but as I always say - service makes a huge deal on how customers perceive a business. Since I left on a good note and felt the staff was friendly, I am giving them 5 stars. read more

I hadn't been to the dentist in 4 years and Dr. Nina was amazing she is working to get my teeth and gums healthy. She explained everything to me so intricately. I felt so welcomed by the whole staff and know that I'm in good hands with Dr. Nina. I got my teeth deep cleaned, cavities filled and had to laser my gums. I'm going back Friday for my second round. Excited to see the change in my smile with some great dental work! read more

Staff was very friendly and they took the time to explain every step of the process to make you feel very comfortable.

Dr. Zadeh and her team did my Invisalign treatment. I could not be happier. Dr. Zadeh has an amazing eye and gave me my dream smile. My Invisalign treatment went seamlessly, and within 20 weeks, I had straight teeth. I highly recommend this office and the amazing team. Thank you Dr. Zadeh! read more

Well, it only took me 40 plus years to her. Oh man, I have been through a lot. So many wacky, cracky, tacky, smacky, jacky, lickity split, drill my sh*+ dentists, it disgusts me to no end. It was just incredible to find this lady. She restored my hope dentistry and how it should be done. Slick little outfit pumping with a solid staff making smiles all day long. The real thing is for the first time, I trust my dentist and that is a wonderful thing. Merry Christmas ;-) read more

Dr.Nina is the best, she and her staff are best in class, professional, and genuinely kind people. I needed a deep cleaning (after my last pregnancy my gums were so inflamed) and it was affordable and painless. My teeth also had shifted so much through these last few years due to pregnancies that I selected to get Invisalign. I am near completion in my treatment and Dr.Nina has continued to refine and is so detail oriented my smile looks the best it ever has. After 5 years of treating me and my family I will continue to recommend Dana Cosmo Dental to all our neighbors! read more

Dr Zadeha is very professional, thorough and kind. Her staff was welcoming, friendly and took time with my son and me. I have found my new family dentist! I know a lot of people have stress/anxiety going to a dentist. You will have a great experience here. I highly recommend this doctor and her team. read more

Dr. Nina was great, she fixed a broken tooth, reset a crown and added a new crown ... All Perfectly. I'm very pleased with Dr Nina' and her Wonderful Staff. As a matter of fact another friend of mine just yesterday had the same opinion. Thank you Dr Nina and your lovely staff for taking such good care of me and my referenced friend. read more

These five star reviews are authentic. I just had my first treatment and I was in good and compassionate hands. A couple of days ago I went for check up first with my sons and that visit was exceptional too but I waited until actual treatment to give my review. Most friendly dental office I've ever been to and the treatment was gentle and highly professional. She even brought me walnuts, cucumber and salt after I felt momentarily weak from the numbing (I hadnt eaten breakfast). wow! wonderful service. But not cheap;) read more

From the moment I called to make an appointment, every member of the staff I encountered was polite and friendly. When I met Dr. Nina it was obvious she is a very knowledgeable and thorough dentist. She had her hands full with my teeth, and even though my appointment required a lot of work, my gums and lips were not sore at all the next day, but instead I had two new beautiful teeth! My first ever appointment at Dana Cosmo Dental was very positive experience. read more

My initial review was based on a checkup/cleaning followed by a relatively simple but necessary procedure involving work on my gums, and the repair of one chipped tooth. Shortly after I was unfortunately hit by a car while riding my bike, resulting in injuries including damage to two front teeth. I requested an emergency examination with Dr. Nina to have her assess the damage. She and her staff made room for me and quickly determined what had to be done when the rest of my injuries healed. Today, two weeks and one day after the accident, I went in to have the damaged teeth repaired. It was all done quickly, painlessly, with no visible reminders of the problem. I mention this to make the point that Dr. Nina and her staff are not just there for their patients when it's easy to be, but are as well when the patients really need help. I couldn't be happier and my only regret is that I can't award them more than five stars. read more

I've tried a ton of dentists and have been disappointed. After reading Yelp reviews, I tried this office. I was really pleased. The doctor is very friendly, patient, calm, informative, and intelligent. Her equipment is computerized. She is able to take extremely up close pictures of your teeth so as to explain what is happening to you. I never felt as if the doctor was trying to make money off of me. She is perfecting her art. I would recommend a visit to this dentist! read more

Just moved to this area and found Dr. Nina Zadeh at Dana Cosmo Dental. From first walking into the office, meeting all the staff, and then meeting the dentist, I was so impressed. Calming atmosphere. Very professional, has all the latest equipment, I had my teeth cleaned and a few teeth bonded. Excellent job!! I am in my 60s so I have had experience with dentists. She and her staff are the best. read more

Not only is she amazing but she is honest! When I went in last time she realized I overpaid for my crowns and reimbursed me. Love her!!

Dr. Nina is fantastic and kind! She got me in, last minute and was able to help me in the best way (fix a crown). She's communicative, she emails, she returns calls the same day, she's got a fantastic demeanor and personality and she doesn't make you "feel bad" like so many do. I would highly recommend her practice for all of your dental needs! Thanks Dr. Nina, for EVERYTHING! read more

Dr. Zadeh is an amazing practitioner. I am a student and avoided the dentist due to the fear of how much it would cost to take care of my teeth. From the moment I entered the office, I was blown away by how caring and understanding Dr.Zadeh was. She took her time explaining to me what was urgent, and what we could wait on. Was extremely thorough with her assessment. Even taking pictures with a camera, so I could see the cavities on a picture (as opposed to an x-Ray.) I had a million questions and she took her time to answer each one with patience. I had to get a crown, and at the point of crown delivery, she was unhappy with the way it was fitting on my tooth. As opposed to just letting me leave the office that way, (I wouldn't have know the difference) she took another impression of my tooth and got a new crown made, at no additional cost to me. It can be difficult to find someone you fully trust with your teeth. However, I can't say enough good things about Dr. Zadeh and her team, and am truly blessed to have found them. read more

Honestly the absolute best dentist ever! Everyone who works here is absolutely phenomenal, ESPECIALLY Dr. Zadeh! She is extremely warm, caring and is the most competent and skilled dentist I have ever had. I whole heartedly recommend Dana Cosmo Dental and Dr. Zadeh, you will have the best dental experience you could imagine I promise! read more
