Office Tour

Take a video office tour of our Endodontics of Orange County facility. Root canal specialist Peter D. Cancellier has state-of-the-art endodontic diagnosis aides including low radiation digital radiography and micro Cone Beam CT imaging at his Irvine endodontics practice. Endodontist Cancellier uses Zeiss optic Microscopes with Xenon lighting. Endodontics of Orange County uses modern root canal location and cleaning techniques that preserve tooth structure and ensure accuracy.

We are the first endodontic office in Irvine, California with a Cone Beam Computered Tomography unit, aka Cone Beam CT or CBCT, for 3D examination of teeth and root canal anatomy. Peter D. Cancellier brought micro CBCT imaging to USC’s dental school. He taught USC endodontic specialty residents how to interpret CBCT images. Dr. Cancellier’s endodontic diagnosis skills, with appropriate use of Endodontics of Orange County’s Cone Beam CT scan, will promptly determine whether your tooth has a good long-term prognosis.

I had a crown that was done about four months ago and it started hurting real bad. It felt like I was being hit in the face with a wet sock full of nickels. I yelped Endodontist and saw Dr. Cancellier's great reviews and he was one of the few doctors open at 8am. They were able to see me the same morning I called and he accessed my tooth and set an appointment for the next morning for the root canal. I heard so many horror stories about root canals so I was scared and nervous. Dr. Cancellier explained the whole process and told me not to worry because he would make it as pain free as possible. He wasn't lying. I fell asleep a couple of times during the procedure cause I was so comfortable. He gave me some pain meds for afterwards when the mouth numbing wears off but I didn't need it at all. Painless during and after. It was an awesome experience. If you need a root canal, save yourself some tears and pain and call this guy right now.


I went to another dentist and was told I needed a ton of dental work to fix a bad root canal, including an extraction and an implant. Well, I am the biggest chicken when it comes to any dental work, so I thought I needed a 2nd opinion. I was so lucky that a friend’s dentist Dr. Uchizono referred me to Dr. Cancellier. Dr. Cancellier had to do a lot of scary things to my tooth, but he did save it. I went in for 2 procedures. I felt no pain. (Not even the shots, which usually take me over the edge). Dr. C and his staff were so nice and caring. I got a phone call the day and a few days later checking on me. I told them I could not believe that I was ok. I laughed and said the only problem I had was that I needed to go in for a massage after the 1st procedure because I was so tense that my shoulders needed to be worked on. The 2nd procedure went as smoothly as the first one. The only difference was that I did not need a massage, because I knew that I wouldn’t feel any pain. Thank you Dr. C for taking such good care of me and for saving me a ton of money and more, for saving me from experiencing pain.


My dentist sent me to Dr. Cancellier for a bad root canal performed by an out of state endodontist. He was very gentle and took a lot of time with me. He noted that I had a significant amount of infection in my sinus and requested that I see an ENT before treating me further.

Later, it was determined I needed another root canal on another tooth which was discovered after I had returned to Dr. Cancellier after nasal surgery because the nerve had died. I was not looking forward to it because of the poor experience I had with a root canal at the other endodontist. The experience I had with Dr. Cancellier couldn't have been different. Both Dr. and staff were gentle and the procedure was done in half the time and with virtually no discomfort. I walked out of his office an extremely happy person.
