  • 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.

  • I’m 29 years old and have always been terrified of the dentist. Novocaine shots in particular have always been my biggest fear. I went to Dr. Orrick for 2 root canals and had a great experience.. he really knows what he’s doing! Dr. Orrick and his assistant Sarah are a wonderful team, and they both have fantastic bedside manner. Also, today was the first time I’ve received a Novocaine injection and by some miracle felt NO PAIN. This experience changed my life..which sounds dramatic, but it’s true. Thank you so much!

  • I agree with other great reviews. I was able to get an appointment to evaluate 3 teeth quickly. Dr. Orrick explained everything and recommended a treatment plan. There was no pressure to get unnecessary and expensive treatment. His office staff worked with my insurance to get the most of it.
