  • I recently had my first root canal experience with Doctor Orrick at the age of 63, and it was outstanding. Throughout the procedure, he thoroughly explained every step and detail, which greatly helped alleviate my anxiety. Although the procedure took a bit longer than expected, it was pain-free, with only minor discomfort during the numbing process, which was minimized by Dr. Orrick's specialized technique. I'm extremely satisfied with my experience and highly recommend Dr. Orrick to anyone requiring this type of care.
