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.
