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 Mission

Our Mission is simple:  To provide you with the finest endodontic treatment available anywhere. Your comfort is our number one priority.  We make no compromises in our commitment to quality care and to excellence in endodontic treatment.

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

Patient Testimonials

I always imagined that a root canal involved significant discomfort and pain. I had absolutely zero discomfort post op. I was told to expect some pain post op and given a medical reason for the type and duration of pain, but no pain ever arrived.

Amazing practice! A role model for all dentistry/medical practices to follow! I was so impressed with everyone in the practice, most of all Dr. Corr. I was very impressed with his knowledge, and careful consideration of every aspect of my care.

I was referred to Dr. Corr several times for different treatment with great outcome. He n his associates provided tenacity and great follow up processes & as such even having a 3 hr appointment things worked out great. Thank you from one Veteran.

The VA sent me to these guys and i'm so happy they did. I had 2 root canals in a week and neither one hurt. In fact i was eating regularly in hours after both operations. Their high tech equipment made me feel like robocop. Staff is super friendly and calls to check up on you. Dr. Boss really knows what to do, he is great at what he does. Thank you to everyone who works there. My mouth hasn't feel this good in awhile.

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.
