My upward appreciation and highest recommendation for you to come to Unistar Dental and to Doctor Hien Tạ. Dr. Hien Ta's professionalism, loving-kindness and friendliness of the whole Unistar Dental team are exceptional & outstanding. I've been going with them for a few complicated processes and then for preventive care and cleaning. So it was a relief to find a highly skilled Doctor/Dentist with highest integrity. Doctor Hien Ta: Utterly professional, up to date technologically, honest, kind and knowledgeable, with greatest attention to details. Every treatment by Dr. Hien Ta at Unistar Dental was impeccable, meticulous and unrushed. In fact, the entire staff is excellent and attentive. If you are looking for the best and loving dental practice and great doctor dentist, Dr. Hien Ta is the Best!

Dr Hien Ta was gentle, very sensitive to my reaction during the procedure; he frequently checked to see if I was ok.

Walk-ins welcome

5:/5 Stars I cannot…read moresay enough good things about this dental practice! From the moment you walk in, the front desk staff makes you feel welcome. They are extremely helpful and incredibly thorough when explaining your dental care plan, ensuring you understand exactly what to expect with no surprises. The dentist is equally amazing and quite thorough during the actual exam and treatment. It is rare to find an entire office where everyone is this dedicated, professional, and clear. Highly recommend!

Warning: My "root canal treatment" here ended with a cracked tooth, extraction, and a $5,000+…read moreimplant. 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.
