Why choose
a BOARD-CERTIFIED endodontist

Choosing a board-certified endodontist means working with a specialist who’s dedicated to saving your natural teeth through advanced techniques and precise, minimally invasive care. At Omni Endodontics, our board-certified endodontists bring years of focused training and use tools like 3D imaging and laser-assisted cleaning to diagnose and treat complex issues with clarity and confidence.

But what truly sets us apart is how we listen, explain, and collaborate. We work closely with your general dentist to create a seamless care experience that respects your time, comfort, and health goals. Many of our patients come to us feeling anxious and leave feeling informed, understood, and relieved. That’s the difference a trusted endodontic team can make.

Hear from our patients

“I was sent to Dr. Nicholas Leon-Guerrero for a root canal and I’m so glad I listened to my dentist. I was worried it was going to hurt, but he explained everything before starting and made sure I was numb and comfortable. It was done quicker than I expected and by that night I was already feeling back to normal. I wish all dental visits were this smooth.”

“I saw Dr. Yeh for a root canal and she was so gentle I didn’t feel a thing. I had been losing sleep over this for days, but it went so much better than I imagined. By dinner time I was eating like normal again. She really knows how to take care of her patients.”
“I used nitrous for my appointment at Omni Endodontics and it made a huge difference for me. I was relaxed and comfortable the whole time and didn’t feel stressed like I usually do at the dentist. The staff kept checking on me and it honestly made what I thought would be a scary procedure no big deal at all.”
“Dr. Deborah Yeh did my root canal and I can’t believe how easy she made it. I’ve had dental work before that left me sore for days, but this time I didn’t even need pain medicine afterward. She worked with so much care and still got it done in one visit. I walked in nervous and walked out relieved.”
