Welcome to Apex Endodontics

If you are visiting us, it is probably because your dentist told you that you need "root canal treatment".  Please don't be nervous, it is our top priority to make sure you are comfortable every step of the way.  

Endodontists, or "root canal specialists", work closely with your general dentist to promote your overall dental health and save your natural teeth.   We will take as much time as is needed to be sure you understand your treament options, and to provide the best possible care for you. 

This website has been developed to acquaint you with our office and team, and is designed to speed up your check-in process by allowing you to complete some of the paperwork before you arrive.  If you are a new patient or a referring dentist, please call 719-282-6600 for your login information

Our office opened in the Spring of 2009 with the goal of being the most technologically advanced endodontic clinic in Colorado Springs. 


Patient Testimonials

Dr. Boss and staff were extremely professional and ready to help. I was impressed by how quickly they were able to fit me into their schedule and devote the time for all of my questions. Dr. Boss uses the latest technology, is very skilled and meticulous, and is great with the patients, especially those like me who like a step-by-step understanding of what he is doing. It is hard to say that I enjoyed getting the root canal, but they made an unpleasant issue into a pleasant and interesting experience.

Dr. Jack and Victor were very caring and informative about my root canal. I was comfortable during the procedure and felt at ease. Thank you! I would highly recommend Dr. Jack if you need to see an Endodontist.

My dentist referred me to Dr Jack for a root canal because of turns and twists in my lower left molar. I was very apprehensive, but the procedure was 190% pain free. I was very comfortable during the procedure and continually reassured by Dr Jack. I got a follow up call the day after and I was feeling amazingly well. I highly recommend this office!

My dentist referred me to Dr. Corr because my molars have four roots instead of three. Also one of my molars had a root that turned at a 90 degree angle. Dr. Corr and his staff not only helped me with my root canals in a timely and comfortable manner, they made sure to follow up after each procedure to make sure that I was doing well and was not having recurring pain. I would highly recommend Dr. Corr and his staff. They truly do care about their patients!

Dr. Boss did a tremendous job navigating a very complex highway of canals. He and his assistants made this procedure "comfortable" and exuded confidence in describing the problem and the corrective actions. Thanks!


I've seen a number of endodontists, but Apex really stands out! Dr. Corr is genuinely passionate about his work, and focused on resolving my issues. He and his assistant Christina were pleasant to deal with. Apex doesn't take shortcuts, but instead focuses on long term solutions. The whole practice seems of the highest quality: state of the art care, sincerely caring, and professional every step of the way. I'm glad there is a choice in my endodontic care, and it's good to know Apex is there.

My visit was complete professionalism from start to finish. Larisa at the front desk made getting an appointment very easy. Then, once I had the appointment any dealings with the administration area, from billing & payment to follow up information went very smoothly. My root canal different than others I had previously because I had a fifth root that was missed by another doctor. But Dr. Boss and his assistant, Ally, worked to take care of it quickly. Those two are a good team and I am glad I had them as my treatment team. Thank you to the entire Apex Endodontics team, but especially thanks to Larisa, Ally and Dr. Boss.

I have finally discovered by experience just what painless dentistry really is. I have so often heard that having a root canal done on you is a very painful experience. Dr. Jack did a root canal on me and it was a totally painless experience. I have a son who is a dentist in the U.S. Army and he had two years of his dental residency at the same place as Dr. Jack, the Bethesda Naval Hospital. That hospital is the best medical facility in all the Armed Forces. As far as I am concerned, Dr. Jack did himself, Apex Endodontics and the entire Dental Profession very proud when he did the root canal on me. Thank you very much for the expert professional job that was done on me. Very sincerely,

David, S.
