I came in as a referral from my regular dentist for a root canal. I had to pay the $300 for the X-ray and wait until Denti-Cal approved the procedure. I called in several months later to check in and they had a cancellation so I was able to get in that way. I would suggest to call in if you don't hear from them. The procedure: this root canal was seem less. Didn't hurt. It was quick and painless. I saw the associate doctor and she was great. Held my hand every step of the way and made sure I was comfortable. Hopefully, I won't ever have to have a root canal again. But i definitely would recommend this place. You certainly have to have a certain mindset when going into a root canal. Stay calm.

I'm happy to provide a fantastic review for Dr. Seyedein and his staff. From the first time I set up my appointment, I was given clear instructions of next steps. The office was clean, safe and very organized. I've been seen a few times and Dr. Seyedein has been very compassionate and also takes his time with me to help me understand the treatments. I would highly recommend this office for your dental needs. The personal phone calls to check on status of pain level are A+. The staff is really friendly and professional.

So a bit over 2 years ago I started to feel the crown on my top left molar breaking apart. I left it untreated because I have a HUGE fear of dentists... the smells, the sounds, the pain! I ended up with a big hole and eventually my gums swelled up and it was coming out of that hole in my tooth. I went to the dentist after YEARS of not going and I got a cleaning done... I cried getting that cleaning. A CLEANING!! Basically I was referred to this endodontic and I was terrified. I came in took it step by step and fortunately everyone made it less scary. When it came down to the procedure, I got numbed which wasn't bad at all. They sat me down and placed the mouth thing on me to keep my mouth open. The doctor started and I had my eyes shut so hard as I waited for some sort of pain. All of a sudden he said he had already cut off the piece of gum and I was so confused and relieved that that part was over so quick. The rest was quicker than I'd thought it'd be and when they finished I was so happy and grateful that the whole process was so easy and painless. I thanked them and now here I am writing this as another thank you. Thank you for your work and for the experience... coming from someone who was terrified, thank you!

Had to schedule a root canal months out from my consultation so that was unfortunate but thank god I wasn't in any pain during that time. Medi-cal covered all of it except the X-rays. The root canal itself was very quick (under an hour) and I felt no pain during except for the anesthesia shots. Very little pain after and a day later, nothing. Thank you Dr. Seyedein!

they haven't done much other than just getting my money, I went back home without getting the service I needed and got anxious dealing with the stuff, I don't recommend it and won't come back.

Excellent experience! Dr. Seyedein explained the treatment thoroughly before he started using my own X-ray and showed me the results when completed. There was no waiting to be seen, and I did not experience any pain during or after the procedure. He and his assistant worked like clockwork together gently and quickly. All his staff are friendly and responsive. Beautiful, comfortable, and very clean office. I'd give 10 stars if I could! I highly recommend Dr Seyedein!

I was referred to this specialist by my dentist. I had pain and discomfort and gave them a call. I was able to be seen the same day and Dr. Seyedein took his time to explain my situations after he saw my scan. He was very detailed and helped me understand what was on the screen, I felt comfortable because he actually took the time to talk to me, the other office I went to was really rude. The staff in the front also helped me with insurance as it was my first time using it. Definitely thanking my dentist for sending me here !

Everyone was very friendly and welcoming. Definitely put me at ease as I don't enjoy going to the dentist and getting drilled on. The doctor was very professional and informative. Explained what he was going to do and why. Good experience overall.
