Warning: My "root canal treatment" here ended with a cracked tooth, extraction, and a $5,000+ implant. I rarely write reviews, but after what my wife went through, I feel obligated to share what was, for us, a nightmare experience so other patients can make informed decisions. My wife went to iSmiles Dentistry on November 15, 2025 because she was experiencing severe pain in one of her teeth. After examining the tooth, Dr. Dang told us the cavity had progressed past the gum line and recommended a root canal. The procedure was described in a way that made it seem like a fairly routine treatment, so we agreed to proceed. In hindsight, we strongly regret not getting a second opinion. What was presented as a straightforward procedure turned into three separate visits. Only on the third visit were we referred to an endodontist (a root canal specialist). When we saw the specialist on December 15, we were told the tooth had a significant crack that was not there before and was no longer restorable. At that appointment, we also learned that the tooth appeared to have a calcified root canal, which can make treatment much more complicated and is often handled by a specialist. This was not something we recall being discussed with Dr Dang before the procedure began, and we were not given the option of seeing an endodontist first. The end result is that my wife lost the tooth. She has gone through months of pain and now faces the long dental implant process, which we were told will cost more than $5000 with a different dentist. What made this situation even more frustrating was the response afterward. When we raised concerns with the office, responsibility was denied and we were told the risks were covered in the paperwork. We felt the manager attempted to place the blame on us. Based on the X-rays we reviewed from before and after the procedure, we still have serious questions about what happened. From our perspective, informed consent should involve a clear conversation about risks and alternatives between doctor and patient, not simply relying on forms. Because of these concerns, we are currently pursuing a claim through the dentist's liability insurance and filing a complaint with the Dental Board of California regarding the informed consent process. Patients deserve transparency when making decisions about major dental procedures. If you are considering treatment here, I strongly recommend asking detailed questions and seriously considering a second opinion--especially for complex cases. read more

I cannot hype up Dr. Nina and the iSmiles Dentistry team enough! Walking into their office honestly feels like stepping into a spa where everyone also happens to be amazing at teeth. Dr. Nina is the kind of dentist who makes you forget you're at the dentist. She's super friendly, explains everything in a way that makes sense, and has this calming energy that makes even the most "oh no..." procedures feel totally manageable. You can tell she truly cares about her patients--not just their teeth, but them as people. The whole iSmiles crew is hilarious, kind, and on top of their game. They somehow make cleanings feel like catching up with old friends. The office is spotless, modern, and actually a place you don't mind hanging out in (never thought I'd say that about a dental office!). If you want a dentist who's both insanely skilled and genuinely fun to be around, run--don't walk--to Dr. Nina at iSmiles Dentistry. They've earned every one of these five stars and then some. read more

I cannot thank Dr. Nina Dang and the entire iSmiles team enough for the exceptional care I received. After undergoing orthodontic treatment elsewhere, I was left with an open bite that returned a few years later. Thankfully, Dr. Nina was able to correct it and close the gap, giving me not only a functional bite but also a radiant, confident smile. The entire process was incredibly smooth and seamless. Dr. Nina has invested in state-of-the-art technology and built a team that is both highly professional and knowledgeable. Every step of my treatment was clearly explained and expertly executed, making me feel comfortable and well cared for throughout the process. I truly couldn't have asked for a better experience.

My husband and I came in for a cleaning and I was amazed by their most up to date on equipment out of all the dental offices I've been to! We got to meet all the ladies that are on their website, they are all really gentle, friendly and comfortable for the environment that can be stressful, I definitely felt at ease and so did my husband that has had a bad past that's made him afraid to go to the dentist. With all the ladies I did have very thorough conversations and they answered all the random questions I had. I am really amazed by the scanning machine they have that can actually show you what's going on with very detailed photos of your teeth, that was probably my favorite part to see. We will be back and have made our appointments for our deep cleanings and future work that's needed, I will keep an update on when that's to come! Other than that it's a very lovely cozy office :) read more

I cannot comment on the dental care here, as I walked into this clinic not as a patient, but as a predental student looking for a shadowing opportunity. The entire interview process was very interesting and informative and felt more like a casual conversation than a high stress interview. I was comfortable the entire time and the vibe of this clinic was really inviting and stress-free. The dentist and her staff were incredibly close, like family, and seemed very supportive of each other, which was really nice. Having caught a glimpse of their personalities and their dedication to patient care, I truly believe that they will do their best to ensure their patients a great experience and exceptional dental care. Even if I can't be a part of their team, I'll honestly always remember them for being so cool and genuine. thank you!!! read more

The best Dental office in OC! Dr. Nina and staff are super friendly & professional.

Over the past few years, iSmiles dentistry has provided exceptional care of my dental health. They also make my wife and I feel at home when we visit their office. This combination of comfort and care keeps us coming back to their Westminster office even after we moved to another part of Orange County. This year, I started Invisalign treatment under Dr. Nina's supervision. Before this, I was intimidated by the process of any corrective treatments for my teeth. But I am currently halfway through a 9-month plan and the entire process has been incredibly easy to manage, with very little discomfort. I owe Dr. Nina a wealth of gratitude for everything her and her staff have done for us. Thank you again! read more

So far great experience! I got new insurance from work and saw all the amazing reviews on Yelp and figured to check out ISmiles Dentistry. I can say I was not disappointed! Dr. Nina was super friendly and her staff was very nice as well. Love the modern technology they have when taking photos of your teeth. Also really appreciate Dr. Nina walking me through recommendations to help improve my gum health. I feel like some dentist try to push you to do procedures to get your money but Dr. Nina was very reasonable and understanding if I wanted to wait and do more research and just also do other preventative actions to help and see if next time it improved. Overall, definitely recommend this place! read more

What can I say about Dr. Nina and her amazing team?! I was referred to them by another patient of their's and I was not disappointed. They go above and beyond every single visit. This is the first dentist I've ever had who can numb you without you realizing it. Her skills are on another level. I also always feel like all of her advice is genuine and she will always give me all the options. Most dentists I've had just want to get paid but that is not something I ever feel with Dr. Nina. You can tell she loves what she does and her team loves working for her. I recently broke one of my veneers and frantically called her and in the same day, not only was she able to squeeze me in and completely fix it, she didn't even charge me anything. I had a wedding that weekend and she took good care of me. If you're looking for the best dentist in town, look no further!! Dr. Nina and team are the best in the business!! read more

This was my first time visiting the office. The staff was absolutely amazing, friendly, informative, and very professional.

I think it's amazing Would definitely recommend this office to anyone who's looking for an amazing dentist. read more

First time experience was great. They have an awesome Doctor and team. Excited to come back!

Dr. Dang and her team are one of the most experience team in Orange County. They are hands down the best in orange county. I've been to couple of dental offices in the past and nothing by far this close to how welcoming they made me feel. I am beyond happy that I found this gem. read more

I asked the Dentist not to touch a certain tooth, and she did it anyway and when the filling came out she started laughing so hard. She didn't apologize as she did it on purpose. I told her that I asked her not to touch it and she responded with "I wanted to". and continued to laugh. she didn't offer to fix it. After supporting this business for over 18 yrs and 3 different owners - I won't be back. read more
