Trauma
Any issues with your teeth, especially infections, can lead to more problems. If more exists, it's needed to seek treatment.

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!

I had an excellent service! Dr. Orrick was very gentle and professional and completed successfully my root canal even though there was multiple complications. Before and after was amazing! Front desk was amazing too! I would give 10 stars if possible. Thank you so much!

Dr. Orrick has come to my rescue for a fourth time now. Staff from the front to the back and every station in between is the best in the business. I’ve been made to feel like a VIP every time I have needed their services. Thank you, Doc & staff!

The best dentist I have used. His staff is welcoming and puts you at ease. They take the time to let you know what needs to be done and will answer any questions with accuracy and patience. Would definitely go to him again if needed.

The office is great. Dr. Orrick is amazing. He has done a few procedures for me and every experience was great. They are compassionate and caring. I really liked how he explains what he's doing and how it will feel before he does the next step. They really care about my comfort as a patient, too. I would highly recommend using Gateway Endodontics for any procedure you need.

I am so shocked at how easy the root canal with Dr. Orrick was. I never had a root canal before, and I'm 40. He has his technique and art down - does it quick, gets you out quick, the process is mostly painless, even the recovery was painless for me. His anesthesia administration was also on point - he got it right the first time. Anytime I've had to get local anesthesia for anything anywhere else, the healthcare provider would have to try several times before I was numb. He was also super transparent about the process; there's a TV screen in front of you where he projects your x-rays and he explains the issue and what he's going to do to treat it. It's nice to know what's happening. As someone who always wants to know "why," I really liked that. Also, the woman at the desk is phenomenal (she's the same one who answers the phones). Her customer service skills, sharpness, and overall clarity and helpfulness is remarkable. She remembers details about you that surprised me (like which medications I'm allergic to, the fact I called her earlier in the week and she kept me in mind - and was able to get me in earlier two days later).

Doctor Orrick was most pleasant and professional throughout the whole process of my root canal. He explained the procedure carefully and I felt at ease with him. I definitely recommend him to anyone who needs to have this done. He’s very gentle and understanding.

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.

I can’t say enough good things about this office. From the first phone call to make an appointment to my final visit I was treated very well by all the staff. I would definitely recommend them.

Dr. Orrick and staff are fantastic. The office answers the phone and works to the best of their ability to get you seen ASAP. The dental work was done quickly, calmly and most importantly pain free. I'm so glad I chose Gateway Endodontics.
