What Patients Say

  • I 100% recommend Richard ORRICK and his staff! When I was pregnant I had to get a root canal. I was in excruciating pain and they squeezed me in on the day that I called. From his staff at the front desk, his dental assistants, to Richard Orrick himself, I received excellent care. They were patient and very focused on what was best for me. I maxxed out the limit on my dental insurance and his team worked with me help cover the remaining costs. My root canal procedure went quickly and smoothly. I have been to other dentists and specialists and this was by far the most positive experience I’ve had. I will never forget how much pain I was in before the root canal procedure and I’ll never forget how much they helped me! God bless!

  • Dr. Orrick and his staff were awesome. I had a very painful and infected tooth and they got me right in and took care of it. They were professional and listened extremely well. The root canal and follow up were painless. I highly recommend Dr Orrick and his practice.

  • 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!

  • Update: Years later now and I have indeed gone back for another root canal! It was excellent! Fit me in right away and it was fast and pain free! I HIGHLY recommend this office and Dr.Orrick, his whole team is amazing! I wouldn’t go anywhere else! I had a lovely root canal done here and I would do it again! Staff and the Dr were friendly and professional, the price was reasonable and the gas must be top notch because I didn’t feel a thing! Highly recommend! Will definitely go again the next time my teeth betray me!

  • 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.
