Our team here at Gateway Endodontics provide relief all while in a comfortable, state-of-the-art office. The first step to healing is just scheduling a visit so that our compassionate team of dental professionals can help with your root canal therapy and endodontic procedures.
Root Canal Therapy
A painless procedure that removes tissue from the tooth allowing it to heal.
Endodontic Retreatment
In cases that a root canal doesn't work, a retreatment may be needed to solve the issue.
Endodontic Surgery
If a root canal won't fix the problem, endodontic surgery may be the necessary procedure.
Cracked Tooth
A crack in your teeth that can keep you completely down. From throbbing to constant pain, we can help fix that.
Trauma
Any issues with your teeth, especially infections, can lead to more problems. If more exists, it's needed to seek treatment.
Nitrous Oxide
An advanced sedation method to help with pain and nerves. It can make some people tired but wears off quickly.
About Us
St. Louis Endodontist - Care Your Can Trust
Most of the patients we see have been putting off their care for much too long, mostly because they find the idea of a root canal frightening. People hear surgery and immediately think of longer term care and pain.
The team at Gateway Endodontics are experts in the field with a passion that drives their experience. At Gateway Endodontics, our why isn’t to take care of teeth, it’s to make our patients’ lives easier and better. Led by Dr. Richard Orrick, we perform root canals and a mixture of procedures related to them.
Why choose Gateway Endodontics?
Most endodontic companies will tell you why, we want to tell you our why… We believe that people should live the most comfortable lives possible. When tooth pain kicks in, it distracts you from everything you have to do, which is why we do what we do.

What Patients Say

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!

The staff were very polite and professional getting me scheduled in around my difficult schedule. Dr. Orrick had the best chair side manners and did a spectacular job keeping me at ease through the procedure. The entire process was as pleasurable as a trip to the dentist can get! I will definitely be recommending Dr. Orrick and Gateway Endodontics to friends, family, and clients!

Dr. Orrick does excellent work. He takes the time to explain each process and during the procedure he was gentle and made sure I was comfortable at all times.

Damn, this guy is good. I'd give 6 stars if I could. I'm not good at the dentist and Dr. Orrick took care of me. I'll never be worried about a root canal again. Thank you!!!

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 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!

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 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.
