- 5 out of 5 stars. “I had a great experience at Ortega Dental Group. The front desk staff and dental assistant were super kind, wonderful, and very helpful, which made the visit stress-free. The doctor was extremely knowledgeable. He was able to clearly tell me that I did not need a wisdom tooth removal or a root canal and explained my options honestly. He also specializes in TMJ/TMD treatment, which was very important to me. They were able to see me the next day and are open on Saturdays, which is very convenient for those who work during the week. The refundable CT scan and not being charged for the office visit really showed their patient-first approach. I highly recommend this office.” — Maria Moreno, San Juan Capistrano
