Microscopic root canal treatment is performed by our specialists and uses a magnification of 25x to see details that are impossible to see with the naked eye. 

The use of a microscope with a trained root canal specialist can lead to finding roots that would otherwise go unseen and
untreated. Microscopic root canal treatments have consistently resulted in a better outcome because they allow for extremely detailed procedures.

“Hands down the BEST place if you have to have a Root Canal that I would recommend. I found this dental group on the internet after searching several places in Orange County. I loved the staff from the very first appointment! ALL were welcoming and very warm and friendly.” -A. R.

Google Review

“I have now had two experiences with Irvine Endodontics, about seven years apart, once each with Dr. Mansouri. In a word, they are amazing. She performed my most recent root canal, and I felt no discomfort.”

Conscious Sedation

Laughing gas is a great way to relax, is very safe, and wears off quickly. In fact, patients who use conscious sedation with laughing gas can drive themselves home after treatment.
