The sweet girl at the front desk literally got me in the next morning. A few hours later I had a root canal. Dr. Lin is very kind and did a great job with this terrified patient. Everyone at this office is awesome. I went from excruciating pain before my root canal to pretty much no pain after. Fabulous office.

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.

I've never had a particularly positive dental experience, until today. I was referred to Tustin…read moreEndodontics after having unusual pain in one of my molars. Since I grind my teeth, I'm used to jaw soreness, but this felt different. I was very anxious about possibly needing a root canal. From the moment I arrived, the office staff were warm and welcoming, which helped ease my nerves. Dr. Farshad Seyedein took the time to listen and was very understanding of my anxiety. He was gentle, made sure I was comfortable and fully numb, and kept me updated throughout the procedure so I always knew what was happening. I also opted for the laser treatment for the infection after cracking my tooth. To my surprise, this ended up being the most positive dental experience I've ever had with minimal pain/discomfort! I'll definitely be recommending Dr. Seyedein and his office to friends and family, especially to my family who share dental experience horror stories.

I have extreme sensitivity in a tooth with a 10-year-old pulp cap. Last May, I bit into an RX date…read morebar (I've had these many times) and felt sharp pain in tooth #4. 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!

His expertise professionalism, and honesty immediately stood out.It's clear from both his credentials and patient reviews that he genuinely cares about doing what's best for his patients-not just making a profit. After my previous experiences, I felt genuinely relieved and confident in his care. I highly recommend Dr. Gharib to anyone who's seeking an honest and skilled endodontist.

My 13 year son had a fall and knocked out his adult front tooth completely out. We went to the ER…read morewhere they placed it back in and splinted it. 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.

any type of dental procedures have always made me nervous. they're never the most pleasant…read moreexperience, and i was especially nervous this time as i'd never gotten a root canal before. i was recommended to visit this office by my supervisor, and i'm so thankful i did. first, scheduling was a breeze. even with a small hiccup in appt mix ups, the receptionist kim was the sweetest person ever, both on the phone and when i arrived for my appointment. the office itself is very modernly decorated, and it's clear they are very up to date about different technologies that help them in their procedures and care for patients. before my treatment, the team took care to break down each part of the treatment process and allowed me to see the number breakdown to ensure full understanding. i love that they offer financing through cherry, as it made it a lot easier to go into the treatment knowing there wouldn't be a hole in my tooth and my wallet by the end of it. every step of the way, dr. dianat and his assistant behgum made sure to keep me in the loop of what they were doing, how the procedure was going. they offered me a blanket and sunglasses to keep me comfortable from the office temperature and bright lights, and they welcomed me to put in headphones to block out the sounds. if it wasn't for the vibrations and drilling, i could've almost fallen asleep. dr. dianat took great care in making sure i was fully numb for the procedure and he and his assistant behgum would consistently check in with me to make sure i was doing good, still comfortable, and to let me know things were going well. at the end of the treatment, i received a comprehensive explanation of what was done and detailed instructions of how to proceed with post-op care. it was the best experience i could have had for a first time root-canal, and i would highly recommend this office to anyone who needs their type of services!

I waited until Monday with no problems and went to my dentist Dr. John Vartanian (Newport Beach) who did the implant for me. He tightened the screw and I was out of there in 10 minutes for free. I believe SoCal Smiles owes me $290 back for their unnecessary scan and incorrect diagnosis. They were trying to sell me something I didn't need and I'm quite upset about how this was handled when I brought it to their attention. I would go elsewhere and not trust this place with your time or money.
