Ashtiani M Andy, DDS

So happy I found Dr. Andy! I needed a tooth removed, then a root canal. I was nervous, but Dr. Andy is a real professional, so positive with a «can-​do attitude» that he instilled confidence & just got the job done with as little pain as possible. His office is state of the art & I couldn’t believe that the one & only root canal I’ve needed was done with laser. The procedure worked so well & within a few days I was feeling so much better; within a week, no more pain. Amazing!

I had 2 root canals from Dr. Ashtiani. The whole process was smooth and painless. I am so happy my dentist referred me. Their office is really nice and the staff is friendly. The Dr. was very knowledgeable and I felt very comfortable. I even told a few friends who plan to go to Dr. Ashtiani.

I went to north bridge endodontist in 2012. It was one of the most frightening and painful experiences I had in my life. Dr. Ashtiani is the owner of North bridge and his associate Dr. Kaun treated me. I had what was called a sodium hydrochlorite accident. My face blew up twice it size full of fluid and I ended up getting two teeth pulled. This was supposed to be a normal root canal referred because of a crooked root. I went to Dr. Ashtiani and he sent me to a nerve specialist six months later. I was diagnosed with nerve damage which they said may go away. It is 2015 and I still have nerve damage. AND when my face regained it shape I had deep wrinkles I never had before. Here is description. I have suffered PTSD as a result.

Sodium hypochlorite accident was first reported in
1974.11 It is a rare complication of dental root therapy.
The majority of reported cases of sodium hypochlorite
accident occurred as a result of inappropriate
introduction of sodium hypochlorite into the dental
root, either by placing the irrigating syringe too far
apically or using too high pressure, which forced the
irrigating solution into the periapical tissues.1
Inadvertent injection into the maxillary sinus had been
reported.9,12 Besides, misuses of sodium hypochlorite as
anaesthetic solution has been reported previously.8,13,14

If you have to get a root canal, make no other choice!
Dr. Ashtiani make’s the normally painful and scary procedure comfortable and pain free!
Professional staff, clean and pretty environment.
At the end of my procedure I was offered a warm «lemon or lavender» scented towel to wipe off with. If felt more like a spa day then a root canal.
Dr. Ashtiani followed up the next day with a phone call.
The experience was what you would hope all dental visits could be.

Very friendly staff! Dr. Ashtiani made me feel very comfortable. He asked me what kinds of music I liked and promptly changed the station to my liking. Befor he began my root canal he made sure I would not feel a thing. Once he started Dr. Ashtiani made sure I knew exactly what he was doing bringing up videos on the screen in front of me. The process was quick and painless. Overall great experience.

I want to echo the other five star reviews for Dr. Ashtiani and his staff. Their office closes at 5:30 (at least on this particular day), and I walked in at 5:33 after a referral from my dentist. I was in pain and especially sad when I walked in the door. The office is beautiful, with lovely views and a very efficient and helpful staff. Dr. Ashtiani took one look at the x-​ray and went to work. I felt like a celebrity being treated after-​hours and the best part is now I am now pain-​free. Thank you!

The office is impeccable, the staff is friendly, and Dr. Andy came out and greeted me himself. He was quick, precise and professional. I am glad that my dentist referred me here, they are professional, friendly and are on my insurance so the cost was minimal for the cutting edge technology they offer.
I can say without a doubt it was a close to a good experience as a root canal can be.

Dr. Andy Ashtiani of North Bridge Endodontics in Petaluma, CA is the best and most compassionate dental specialist in Sonoma County. Recently my husband needed an emergency root canal on a holiday 3-​day weekend and Dr. Ashtiani was the only Endodontist in our area who could be reached and was willing to help him. In fact, he came into his office and got him out of pain very fast. I don’t know of any other doctor that would have done this! I can’t say enough good things about Dr. Ashtiani and his practice!

My experience with Dr. Andy (Ashtiani) was a resoundingly positive one.
I highly recommend North Bridge Endontics!
The office is immaculate and I was treated with respect and with genuine, focused attention. I was a bit nervous as this was a proceedure on a front tooth but his assistanct Amy’s confident, calming presence helped me feel at ease, as soon as I arrived.
Dr. Andy explained everything clearly throughout the consultation visit and was happy to respond to folllow-​uo questions that came up after I’d left the visit. The root canal procedure was smooth and Dr. Andy was sensitive and responsive the entire time. I appreciated his call later that evening to check on me at home.
I experienced zero pain both during and after my visit!
Dr. Andy is clearly a seasoned professional, who brings a deliberate, sophisticated, and caring approach to his work!

My son was referred here by our dentist. I will be calling our dentist today to urge them not to refer this doctor anymore. Yes, the doctor called a couple days after my son’s route canal to check on him, but that was the only positive part of our experience.
We were told the canal would take about an hour. He was in for over two hours, and we still had to come back again when the other doctor was in. It sounded like the one filling in for Ashtianti was super incompetent. She could barely speak English.
They never seemed to care how much pain my son was in. It has been a week and we are worried about infection. I called to bring him in and they can’t see him today, and she did not seem to care about the patient AT ALL!

My experience here was wonderful. I can’t say thank you enough. I am 8 months pregnant and NEEDED work done. Unfortunately I always get extremely anxious when going to get any dental work. ALL of the dental assistants were wonderful and great at easing my nerves. The Dr was quick and made my experience painless.
I had a missed call and when I checked my voicemail it was Dr Ashtiani calling to check up on me and see how everything was going. The actual DR called me!!! Where does that happen!!! I was shocked and very impressed my this. I just wanted to say thank you for a wonderful experience. I will be coming back here to get work done.
Not to mention the waiting room and reception staff was amazing. I can’t say enough good things about this place. Again, Thank you.

Dr. Andy was terrific, but his office staff is shotty at best. I had a root canal in December 2010, and after my insurance paid their portion, I received a bill at the end of May 2011. Not good!
This was after the office told me in January that my bill was settled.
Never again!
