Morad Milhem, Orange

This is my second Root Canalat this office , The reason I came back to Dr. Garib because he did super job on my first Root canal , it was painless, in less than an hour was out of the office , Dr. Garib cares about his parents and he will explain the procedure step-by-step great doctor and staffs. I will definitely recommend anyone for Dr. Garib should you have any root canal issue,

Carla T, Gardena

I can’t believe how smoothly everything went. It was the first time I’d had any nerve treatment, and I was quite nervous, but Dr. Gharib made me feel so comfortable and I hardly felt a thing. Really grateful.

David , Irvine

First root canal ever and would definitely refer anyone here, super gentle and quick. And I hate needles but Dr. Gharib has that magic touch!

Heather R, Irvine

I needed an emergency root canal after an evening of excruciating pain in my back molar. Dr. Gharib was recommended and contacted by my dentist on Sunday evening. He had me come into his office first thing Monday morning to look at my tooth. His office staff couldn't have been nicer and more welcoming. Sharon and Christina were both wonderful and Dr. Gharib had the nicest bedside manner. He was very compassionate and gentle during my root canal procedure and alleviated my pain immediately. He was even thoughtful enough to contact me later that evening to check in and see how I was doing. Dental emergencies can be scary and quite painful; I'm so thankful that I was able to be seen and treated by Dr. Gharib and his team. Ironically, my co-worker's son needed a root canal shortly after mine, and I was able to refer him to Dr. Gharib, who fit him in right away.

Crystal M, Winchester

Great practice

CB, Orange County

Excellent treatment on my root canal. Will definitely return if necessary.

Samuel K, Irvine

I'm a low-income Orange County resident. When I found out I needed root canals, I called upwards of 30 endodontists in an attempt to find a place I could afford without having to compromise on quality. I found Dr. Pete. He is one of the least expensive doctors in the area, and he is excellent at his job. I've had three root canals done by him, so I can personally attest to his quality, and the teaching positions he's held indicate that he is highly respected in his field. As for his staff, Christina and Shannon, they are platinum-tier. Christina goes out of her way to make sure my billing information is crystal clear. Shannon is skilled and good at putting people at ease. I have severe dental anxiety, so I don't like to hear ANYTHING about what's going on during my procedure. You might think that would impede communication between dentist and assistant, but Shannon and Dr. Pete take it in stride and still manage to work in tandem as if they were psychic. Thanks for all the help, guys.

Humberto M., Irvine

I had a great experience getting my root canal done with Dr. Cancellier. He knew exactly what he was doing, he did a great job and he was a true professional. Not only that, he was very personable and he made the experience as enjoyable as possible. He even showed me a Stevie Ray Vaughan performance he found on Youtube after the procedure. I was pain free the same day as the procedure. I 100% recommend Dr. Cancellier to anyone in need of a root canal.

Freya R, Costa Mesa

Dr. Cancellier handled my root canal like a true professional! I was nervous about the procedure and the pain, he walked me through it and I felt a lot better! During and after the procedure my comfort was his concern!

Charles T, Lake Forest

When a tooth requires a root canal procedure, you want these guys, they are the best. 6 stars The tooth pain started while on vacation and escalated to 15 on a scale of 1-10. However I was on vacation out of state. My Dentist started me on an antibiotic with Tylenol. By Thursday afternoon the throbbing pain was off the chart and required immediate attention. Called their office, they said come over now. Sharon and Dr Cancellier stayed hours over closing time but completed the procedure and within a few days I was pain free back to normal. They are a fun team, laugh, humor, with great 70-80's music (LOL). It is nice to know real professionals still exist, have fun and do an awesome job.Thank you all

Ivette D., Riverside

Dr. Cancellier and his team are wonderful! Best experience I have had with a root canal. And it's a ROOT CANAL!! They are patient and genuinely care for your well being. My 6 year old daughter even enjoyed going and waiting for me, they are all so kind. Thank you Dr. Cancellier and team!!

Steven Culley, Orange

I was referred to Dr. Cancellier by my dentist for a problem tooth. Dr. Cancellier was great and took care of the root canal quickly and comfortably for me. The office staff and assistants were all very nice and helpful throughout the process. I would definitely recommend Dr. Cancellier for all your Endodontics needs, should you need it.

Richard O., Newport Beach

As a University Professor I rate Dr. Cancellier and his staff an A+ for professionalism, service, and dental care! I recommend Dr. Cancellier to anyone who wants excellent Endodontic care...

Sasha, Westminster

I have always been afraid of getting a root canal, but Dr Cancellier and the staff made it quick and painless .

gene c., irvine

Everyone at the office, from the receptionist to Dr. Cancellier himself, gives you top painless service. everyone at this office

Judy, Irvine Cclif

DR Cancellier is an excellent and amazing endodontist I would highly recommend him.

Jennifer B, Santa Ana

Dr. Cancellier and his office was amazing! He saved my from tooth and I had minimal pain and healing time. I was so worried I would have to get an implant. So do yourself a favor and get a second opinion with Dr. Cancellier before you get an extraction. Thanks again Dr. for everything!

Michelle , Yorba linda

This poor doctor had his work cut out with me. Had to come in for an emergency root canal. He was much more gentle than my regular dentist. I found him via yelp. He's amazing.

Allen Kemnitz, IRVINE

On 3-1-2017 Dr. Cancellier performed a root canal on me. It was painless. The Doctor and his assistant were very professional. I strongly recommend him for your dental needs.

Greg Moore, Irvine, CA

Dr. Pete's kind and gentle nature makes you feel immediately at ease with the dentist office visit. My wife is almost a dentistphobe, but she goes to her appts with Dr. Pete without me having to drag her there. She is so comfortable with Dr. Pete that she takes her father from Northern California to see Dr. Pete when he is in town visiting.

Barbara L, Newport Beach

Positive experience; competent and friendly practice. Wouldn't hesitate to recommend.

Jaclyn, Newport Beach

Dr. Cancellier and his staff are fantastic. I had a painful tooth and was little nervous to have the treatment done. Dr. Cancellier made me feel at ease immediately. He explained the entire procedure before hand and let me know what he was doing during treatment as well. I've never been afraid of shots but his technique for administering anesthetic was by for the best I've ever had! I swear I didn't feel a thing! While root canals are never fun I have to say this was one of my best dental experiences ever! I had a little tenderness after the numbing wore off but by the next day I felt great. I would definitely go to him if I ever need another root canal.

Birgit, Lake Forest

I went to Dr. Cancellier's office after a failed root canal from another dentist. Christina, the administration was so nice and welcomed. Dr. Cancellier explained everything very well and did the root canal and surgery to save my tooth. It was not painful and the Dr. and his assistant took very good care of me. He called me next day to check on me. I would highly recommend Dr. Cancellier and his staff for Endodontic treatments, very professional and wonderful. Excellent service

Christine D, Irvine

I had a good experience with Dr Cancellier and his staff for a re-work of an old root canal that was abscessed. I felt well cared for during and between the two-part treatment. My health was always their focus and I am very happy with their honesty. When my insurance company paid more than they expected, they even refunded the difference to me!

Missy T, Irvine

Great Experience. Pain free. Doctor and staff were very friendly, and made sure to put you at ease during the whole procedure.

Erin Rohac, Laguna Niguel

Dr. Cancellier and his staff were wonderful. They were extremely helpful at reassuring me of the procedure and its ease. There was little to no pain and they have great table-side manner to keep my mind off needles and drills. I am very happy to have been referred to them.

Larry E. , Lake Forest

What a pleasure to find professional persons that care in my time of need. The staff was friendly and attentive. The Dr. knew what he was doing and took extra care during the procedure. Even the house music changed to my preferences. Thank You

Lloyd G., Aliso Viejo

Where can i start, this is my second visit and like the first visit, Dr. Pete and his very professional staff were up to the task of handling my tooth problem. I lack the appropriate words to fully express the care he and his assistant gave me and the followup is outstanding.


Really a superb craftsman and artist. first rate work and a very inviting overall office experience as well.

Miles Dimitri Baker, Orange

Experienced very little pain during the Root Canal procedure. Dr. Peter was really nice and friendly. The rest of the staff was great too. Best price I could find on top of that. Highly recommend.

Mike S., Irvine

My experience at Endodontics of Orange County was a surprisingly pleasant one. I prepared myself for a painful visit but I didn't feel a thing. Dr. Cancellier was super friendly and explained everything that was going to happen before hand. I've had a few root canals in the past and none were this easy. And when has a Dentist ever called you to see how things were going? Well Dr. Cancellier did and it blew my mind. He also has a great taste in music which he played in the office during the procedure. I highly recommend Dr. Cancellier for anyone needing an Endodontist.

Greg B, Irvine

Excellent care in a courteous and professional atmosphere! I highly recommend Dr. Cancellier.

Alfonso L., Irvine

It was a very nice ambiance and a feeling of welcoming, everything was done on a timely manner. I felt really good taken care, all was very professional, doctor is very courteous and considerate. I had a very positive non painful experience. I highly recommend dr. Cancellier.

Joann S, Irvine

I Was able to get in to see Dr. Cancellier same day as referral from primary dentist. Christina was excellent at scheduling and following up as well as taking care of insurance issues. Dr. C and Sharon were able to change what was a dreaded experience into an easy and painless one. This was my second difficult root canal with excellent results. Dr. Cancellier personally followed up with me the next day to make sure that I was ok. Would definitely recommend to anyone who needs a professional, efficient, considerate ( and even funny) endodontist and staff. Thank you.

philip chandler, newport beach

I was recommended to this fine facility by my dentist, everything went very nice and Peter and is his staff are as friendly as they are overqualified and professional.

Gayle Jacobson, Irvine

Dr. Cancellier was excellent in treating my root canal. I am typically not a great dental patient (to say the least) The staff was excellent at helping me relax. I highly recommended this office for the dreaded root canal.. Truly , a root canal is easier than getting a crown.

Corina, Irvine

Dr. was awesome, as was his assistant. Made me feel completely at ease. Played classic rock in the office. My root canal was quick and painless. He even called to check up on me. I would recommend him to anyone.

Cheryl C., Irvine

Dr. Peter Cancellier and his staff are absolutely wonderful!! I can't say enough about how great they are--so professional, knowledgeable, friendly, and very accommodating!! If you need an endodontist, Dr. Cancellier is the one you want. I've had three root canals performed by him, and all could not have gone more smoothly!! He and his assistant, Sharon, are so personable that you are actually enjoying yourself!! The welcoming environment begins when you are greeted by Christina at the reception desk. She has a great personality and is very efficient, while making you feel right at home!! The office, itself, has a wonderful, refreshing feel to it, making you feel very relaxed! I highly recommend Dr. Peter Cancellier and his staff for your BEST possible care!!

James S., Irvine

I found Dr. Cancellier to be extremely knowledgeable and professional. The staff was just as good.

Harald S., Huntington Beach

no waiting, great/relaxed/calming atmosphere and most important he has done a fantastic job!

John B., Irvine
