From the moment I arrived, everyone made the process smooth and comfortable. Dr. Norouzi is very knowledgeable and took the time to carefully explain everything, which I really appreciated.

Overall, Dr…read more Kevin Su and RDH Shyla have been professional and trustworthy, which is why we kept coming back. However, our recent experiences have been very concerning since a new dentist, Tara Norouzi, joined. First, both my wife and I specifically scheduled appointments with Dr. Su, but without prior notice, our exams were handled by Dr. Norouzi instead. We were not informed or given a choice, which felt inappropriate. Second, my wife had a troubling experience last year. After learning she had prior Invisalign treatment, Dr. Norouzi strongly insisted that her teeth were in very poor condition and recommended crowns, dismissing her request for conservative treatment. She was told that without crowns, her entire dentition could deteriorate. Concerned, she sought a second opinion overseas at a top dental hospital, where doctors determined it was a minor issue treatable with medication. The problem resolved quickly at minimal cost. More recently, I experienced something similar. I went in for sensitivity in a molar that had previously been filled. Despite explaining clearly that the tooth was sensitive to temperature and pressure, I felt my input was not fully understood. Based on testing, Dr. Norouzi concluded that the tooth nerve was "dead" and recommended extraction and a crown, which seemed inconsistent with my symptoms. When I asked about more conservative options like a filling, those were dismissed, and I felt pressured toward more aggressive treatment. The communication was tense and not patient-centered. After these experiences, I've decided to cancel my future appointments. I strongly recommend patients seek a second opinion before proceeding with major dental work.

    Dr Ash is simply the best…read more I have been going to Dr Ash since 2021, back when I was at Chapman University. My first visit was after I chipped my front tooth in an accident. I did a ton of research when this happened to me because I was not only in a ton of pain but was missing half of my entire front tooth, and Harmony Dentistry had by far the best reviews, so I decided to go with them and I am so glad I did. When I made the appointment that night of the chip in complete hysteria, he moved appointments around and opened up the practice at 8 am the next day so I could come in as soon as possible and not miss my important class finals. The day I went in, they placed temporaries on two teeth to fix my smile and make me feel more comfortable, and Dr Ash made sure everything looked perfect and that my permanent teeth were ordered and ready. That experience completely changed the way I view going to the dentist and doctor standards in general. Since then, I have continued seeing him not just for cosmetic work, but for cleanings, cavities, and anything else I have needed. I now live in LA and still make the drive from Beverly Hills to Mission Viejo about twice a year because I genuinely love this place, the people, and Dr Ash. The environment is amazing, and I have never felt more comfortable or trusted a doctor more. He truly is one of a kind. He always follows up after appointments to check in, which is rare. For example, today I went in to get a cavity fixed, they gave me my favorite complimentary microbial mouthwash that is normally pricey and great for your gums, and Dr Ash personally called me after the work day to see how I was doing. Not only that, I have texted Dr Ash many times on multiple occasions with questions and concerns off the clock, and he always responds promptly and is incredibly helpful. On top of that, they have incredible technology for super easy X rays and seamless retainer and Invisalign tray making, and everything is extremely efficient. The office itself is spotless, great layout and has beautiful natural light with great views. I could not recommend Dr Ash or Harmony Dentistry more.

    I had gnarly anxiety around the dentist, and it prevented me from regular dentist visits. The folks…read moreat Harmony have totally turned that around for me, and now I look forward to my visits. They are personable, transparent, and explain everything clearly. I don't feel like I'm being talked at, or made to feel shameful about my teeth. They also gave me a best coarse of action to move forward and made everything feel much more manageable. I left the office with confidence! I don't care where I live in OC, I will make the drive every time.

I've been going back and forth between veneers, gum contouring or both and Dr. Scott Rice was able to explain pros and cons to both options without being pushy. My teeth and mouth were perfectly fine and healthy. I've had braces twice in my life, so they were already straight and aligned as well. Many of the other dentists I had gone to were trying to sell me on a full set of veneers, but I wanted to keep my natural smile/teeth but just achieve a more improved look with less gum when I smiled and an even gum line. That's exactly what I got and I'm so happy I found him because I decided to switch over to them as my regular dentist now. Their service, professionalism and expertise is so worth it! The fresh baked cookies don't hurt either Lol! It smells amazing in there everytime! The thing is there are many well trained, knowledgeable doctors out there who can give you what you want, but the ethics and moral character are hard to find. He was more focused on what I wanted, what made me happy than achieving the perfect smile (unless that's what I wanted of course). Your smile is an investment and at the end of the day you're the one paying. You want to be sure it's the look you want and are happy with it and also find a dentist who can provide their expertise, knowledge and opinion without feeling like their trying to sell you on the most expensive procedures. He kept my well-being at the forefront and I can't ask for anything more. He made me feel safe and heard and that's what won me over. Dr. Scott Rice actually cares and listened. I trust him with my care. He's a rare gem! During the procedure, I was involved every step of the way. Asking for my opinion, telling me what they were doing, asking if I was okay. Answered all of my questions. Healing was pretty fast, no complications. I had gum contour and composite veneers done. If it's not already obvious, I highly recommend coming to Rice dentistry for all your dental needs. I'm beyond happy with them and will continue to come back and recommend them to anyone asking. The staff are amazing as well, the whole team are very thorough and provide A+ customer service and treatment.

I was able to make an appointment with Dr. Yu a few days later he took the time out of his busy schedule to survey the tooth and told me that it was a concussion and to let it heal. I came back a couple weeks later and got some x-rays and thankfully it healed about a month later. I'd appreciate his care and great bedside manner, even my anxiety. I recently came back for a check up and cleaning and I have to admit I got the best cleaning from Cindy. She started with asking me about any concerns I had and I mentioned enamel erosion. Well what I thought was enamel erosion was a lot of tartar on the surface of my teeth and she was able to really scale through all my tartar as well as clean the stains on the bottom of my teeth and make my teeth polished, clean and shiny like a new set of teeth!

I really believe that dental health is so important to overall health and living a long and healthy life. I insist on cleaning every four months. My gums are so important to me and my health. I had to wait six to eight months to get in to see Dr. Yu, but it was worth it. My past dentists tried to upsell me or tell me I needed unnecessary work, but that will not happen here. I highly recommend Dr. Yu.

And then they started to upsell and push a $1,200 cleaning... They were justifying the claim that they look out 5 to 10 years out, also saying they can't do a full cleaning since it will impact the quality of the future specialized cleaning and after they report to insurance I would be locked out and not able to be covered for it in the future if I did not do it today it would be more expensive later over $2k. So of course cleaning was really rushed. I went to my old dentist a month after and they said it looked like my teeth were not cleaned or polished since they last saw me. I sent the X rays/imaging from the visit to a dentist friend and they said it was a very extreme solution for something that can be managed with personal routine changes. They are entitled to their opinion and how they operate as a business nothing against them. This is a heads up if you decide to go in.

From the moment I walked into Honest Oral Surgeon, the staff made me feel at ease. They were professional, friendly, and very patient. After taking my X-rays, they carefully explained everything to me and answered all my questions. I also watched a pre-procedure instruction video, which helped me understand what to expect. When I met Dr. Kim, he was professional, clear, and straightforward. He explained my treatment options concisely and also pointed out potential risks related to my other teeth. After discussing everything together, we decided to take a conservative approach -- remove the wisdom teeth first and monitor the other teeth to see if they could recover over time. I really appreciated being involved in the decision-making process. The surgery itself was excellent. It was my first time receiving anesthesia and having teeth extracted, and I can honestly say I felt absolutely no discomfort. Dr. Kim removed both wisdom teeth efficiently and skillfully. (Yes, I could hear the drill and some hammering sounds -- which was a little funny -- but I felt zero pain.) After the procedure, I followed the instructions carefully, took the prescribed medication, and applied ice as recommended. It's now the second day, and I have no pain at all -- not even noticeable swelling. This is actually the longest Yelp review I've ever written, but I truly felt it was deserved.

We were charged over $1,000 out of pocket (more than $3,000 before insurance) for something that shouldn't have been done. They also took an excessive number of X-rays--18 before a routine cleaning, and many more afterward just to "check" their work. For simple fillings, they removed far more tooth structure than expected, leaving the tooth hollow and then recommending crowns as a follow-up. While the staff appears friendly, it often feels like they are pushing as many procedures as possible rather than prioritizing what is truly necessary for the patient.
