    Preservation Dentistry! I've had such a positive experience here. Dr. Trieu is not only kind but truly takes the time to make sure you feel comfortable and fully understand your dental care. I never feel rushed, and he's always happy to answer my questions, which makes each visit stress-free. The dental clinic is clean, calm, and welcoming, and the staff is both friendly and professional. I had a routine dental cleaning and check up with May, the dental hygienist, and she was amazing! Dr. Trieu and the hygienist worked together and taught me how to take care of my teeth properly so I can avoid needing any treatment. What I appreciate most is their honesty and the conservative approach. They don't push unnecessary procedures, which has saved me a lot of money! I also brought my son for his first visit, and he also had a great experience with the dentist. It's such a relief knowing I can trust Preservation Dentistry for our family dentistry needs in one place. If you're in Irvine and need a dentist who genuinely cares and makes each visit a breeze, I highly recommend Dr. Trieu and his team. I actually look forward to seeing my dentist!

    I've lived out of state for several years now and still fly in just to go to Preservation Dentistry. That alone should say how much I appreciate the kind of care I receive from Dr Trieu and his team. Everyone at the office greets you with warmth. The office is clean and updated, with state of the arts equipment. Dr Trieu truly cares about his patients. He spends time educating you on the proper habits so that you can maintain good oral health and avoid unnecessary procedures. If he can save a tooth, he will. If he can help you save money, he will. A very different mindset from most other dentists who will jump at every opportunity to do a filling or root canal. If a procedure is absolutely necessary, he will put in the extra time and effort to make sure it is done right, on first attempt. Had I had found them earlier, all my root canals done at other offices could have been avoided. Dental hygienist May does wonderful work on my teeth cleaning. She is thorough at every visit, never rushing through the process. She, too, cares about people's teeth. She wants nothing more than to help you improve your oral health. You will learn some great trips and tricks that actually work. Together with Dr Trieu, their preventative approach have kept my teeth in good shape. Truly grateful to have them both care after me. I highly recommend going to them for all your dental needs.

    cerec machine, making my same day partial crown in office!

    Dr. Trieu is exceptional. I've worked with many dentists and as a dental hygienist myself, his attention to detail is one-of-a-kind. I had a big cavity on my tooth that was hurting and other dentists in Washington suggested I need a root canal and a crown. I used to live in Anaheim but even now I that moved to Washington, I will still fly down to see Dr. Trieu in Irvine! Dr. Trieu was not only honest about my dental work but also took a conservative approach to the treatment. He was very detailed, explaining each step of the procedure. Dr. Trieu made me a partial crown so I can keep the healthy part of my tooth. They had a same day CEREC crown making machine so I got to watch my crown being made and everything was done in just couple hours. I also got a routine cleaning with his hygienist, May, and she did an exceptional job with the cleaning, gentle yet detailed and thorough without any discomfort, exactly what you want from maintenance visit. She measured my gum pockets and also showed me her approach of keeping the gum healthy. She used salt washing technique to polish my teeth which is my favorite part of the cleaning. The entire staff was incredibly nice, ensuring my comfort throughout the visit. I'm so grateful and lucky to have found such genuine and honest team, which is rare in this economy. Most dentists I've visited and worked with primarily focus on treatments and more procedures. Dr. Trieu wants you to save money and save natural teeth and I really appreciate this approach. I will undoubtedly recommend all my friends and family (even my own patients) to come here!

    I just wanted to thank Dr Trieu for having noticed that my bite Gap was off and was patient with me and helping me fix it!

Behgum was patient and accommodating during my consultation as I struggle with X-rays. Dr Dianat thoroughly explained my options and even called my dentist to discuss my treatment. I was a bit undecided on my treatment option but his entire staff was patient and supportive - even drawing up two treatment plans and explaining the cost differences to me (thanks Kim and Lailia). I ended getting a root canal (my first one) and the process from start to finish was painless and the best experience one could hope for. Behgum assisted during my root canal and made me feel at ease right from the preparation stages. She is kind and provides intentional care throughout the process, checking in to make sure I was ok and explaining where we were in the process. She helped me through at least six X-rays and it was a breeze! Everyone showed kindness, support and the highest level of care. Dr. Dianat performed his work quickly and I felt no pain during the procedure. They are truly professionals at what they do and I would recommend this office to anyone who needs a root canal.

At the advice of my regular dentist we needed to get a root canal. We went to one consult which did not go well. The Endodontist informed me in order for my son to have a root canal he needed sedation. I did not agree as he is really calm and compliant. He does have epilepsy and cognitive delay but I felt he would do ok as long as he was numbed correctly and he felt comfortable. I honestly got the impression he just did not want to do it. So I spent the next week trying to find another option. I decided to go with Dr. Dianat based on my conversation with his staff and patient reviews. Dr. Dianat was absolutely amazing with my special needs child during a root canal procedure. From the moment we arrived, he showed incredible patience, kindness, and understanding, which immediately helped put both my child and me at ease. He took the time to explain everything clearly, worked gently, and made sure my child felt comfortable throughout the entire visit. I am beyond grateful we found Dr. Dianat and he exceeded all my expectations. The procedure went smoothly, and the care and professionalism we received were outstanding. Kim from his office called me today (next day after procedure) to check on him. I'm so grateful for the positive experience and would highly recommend Dr. Dianat to any parent looking for an exceptional endodontist.

For six months I dealt with sensitivity, mainly triggered by hot and cold. I could eat and chew just fine as long as I started chewing on my left side first. Last May, I spoke with my dentist, had X-rays taken, and he told me I'd eventually need a root canal. He didn't give me any other solutions, so I just waited to see if things would get worse. Six months later, I scheduled an appointment with Dr. Gharib's office because the sensitivity was getting to me (even though it was on and off), and I started feeling pain up my cheek. I was worried about potentially having an infection or, even worse, an abscess. Christine at the front desk was so kind and accommodating. It was easy to schedule an appointment. She told me that Dr. Gharib is very conservative and only recommends procedures when absolutely necessary. I figured that was just something she said to everyone. At my appointment, I had X-rays done and reviewed them with Dr. Gharib. He was very kind, soft-spoken, and answered my many (many) questions while listening intently to my concerns. I did not feel rushed at all--I felt like I was actually being heard. After his examination, he didn't see any infection on the X-ray, but it did show a slight fracture in the pulp cap filling, which could be the cause of the heightened sensitivity. He didn't pressure me to do a cone beam scan or even suggest it; I personally requested it because I wanted to be absolutely sure there wasn't an infection at the root, since that would make a root canal necessary. The cone beam scan confirmed I had no infection whatsoever--thank goodness. He sat with me for a long while discussing what I could do to help the sensitivity and the slight fracture. He said it might be as simple as replacing the filling with an inlay or onlay, but since my pulp cap is very close to the nerve, that carries the risk of needing a root canal if it fails. He suggested trying Sensodyne for a few weeks and then having my dentist check whether an inlay or onlay, to replace the filling, is an option. There's a chance that might fix the problem. After my appointment, I felt so much more at ease. I was relieved that I didn't have an infection and grateful that I actually had options before committing to a root canal. Dr. Gharib even wrote me a long email afterward, reiterating everything we talked about. That, right there, is a dentist who truly cares. If and when I ever need a root canal, I'll be going to Dr. Gharib. He is professional, honest, thorough, and welcomes ALL questions. All the positive reviews you've read are true. Not every dentist cares like this!

We agreed we will discuss a resolution at a future date after we exchange additional documentation with each other. I will update this post when appropriate based on new information. ORIGINAL REIVEW: I got my root canal here before my general dentist could place the crown. After the root canal I went back to the general dentist and upon taking X-rays told me the root canal was done improperly and was incomplete. I had to back to Dr. Lin for a second root canal on the same tooth. Upon going back the GP he said it's a little better but he's still not completely satisfied but would "probably be ok". Facing the reality of having to do a third root canal on the same tooth for "probably" not necessary, I did the crown after the 2nd root canal and hoped for the best. Flash forward about six years later and the same tooth got an abscess bleeding out to the gum. Ended up losing the tooth and had to get an implant suffering through more dental procedures and will end up costing almost $9,000 out of my own pocket for all the work to be done diagnosing and treating the problem with three different specialties and doctors. If the tooth couldn't be saved by Dr. Lin he had a duty to tell me that and then I could have gone to a different doctor or had the tooth pulled. Obviously I couldn't go back to Dr. Lin and this practice because he had already proven to me he is incompetent and can't be trusted. I would advise you to avoid this practice based on incompetence, failure at duty of care and the dangerously poor skill of the doctor. I'm filing the appropriate complaints with the licensing and insurance company. If it were up to me, this doctor would have his license revoked.
