Thank you for selecting the endodontic office of Dr. Edward L. Kasper and Dr. Logan T. Bell.  We are an endodontic specialty practice dedicated to exceptional care using state-of-the-art technology.


Our Mission is simple: to provide you with the finest endodontic treatment available anywhere, in a pleasant and courteous atmosphere.


Our "make no compromises" philosophy allows us to treat patients to the utmost of our abilities in a way that will lead to a pleasant experience for you.  This is a tall order but we feel that taking time with our patients and being open to their needs is of the utmost importance.

With our new office we have made sure to provide our patients with the most up to date techniques and cutting edge technology so they receive the best quality care in the most comfortable environment.

Practice Profile

Our office is known for its commitment to excellence.  We use the latest technology including the surgical operating microscope which offers increased magnification and illumination for all procedures.  Whether we are evaluating the outside surface of a tooth for a crack, locating miniscule root canals, removing a broken file from a root canal, ensuring the canals are thoroughly cleaned, or filling the root canal systems, the microscope benefits treatment.   Even the smallest detail is brought clearly into view.  We also replaced conventional dental x-rays with digital radiography. This advancement significantly reduces radiation exposure to our patients and eliminates the hazardous byproducts of film developing.

Always on the forefront of technological innovation, we have converted to digital record keeping and use of the Internet for the convenience of our patients and referring doctors.  For example, we encourage you to pre-register at this web site to save you time when you come to our office for your appointment.  It is simple to use.  Please call our office for instructions.


Together, our commitment to you is that you receive the best care that is possible today.

I had my first root canal experience with Dr. Bell. While I was definitely not looking forward to having to get this done, I have to say that Dr. Bell made it as comfortable and as easy to manage as possible. He explained everything and took time to answer all of my questions. My procedure ended up taking some additional appointments but each time he provided me with the information I needed to understand what was going on and the compassion I needed to not feel frustrated and upset. I absolutely love how the friendly and helpful the office staff is and how they call to check on you the day after your appointment. Not that I want to ever get another root canal, but if I did, I would only see Dr. Bell!

Wow! Has dentistry changed over my lifetime...No pain, lots of dedicated, smart, talented, friendly people here. Dr. Kasper thank you for your talent and also thanks to all your staff. I had an informative, actually fun experience for having a redo on an old old root canal. And the flavors are yummy.

My son Josiah is 9 years old and recently had Dr. Bell perform a root canal over the course of 2 visits.  I felt that he was very caring and helped the procedure to go as well as possible for a 9 year old!  He was very helpful in explaining exactly what he was doing and showed a lot of care for my son.  Thank you for making this a pleasant procedure!

Dr. Bell did a fantastic job! I was fortunate enough to have the entire procedure completed in 1 day! I am a naturally curious and analytical person. Sometimes, logical to a fault. Dr. Bell explained every step and included his logic and reasoning. Both of which are incredibly sound. The team there is fantastic. I was fortunate enough to have Julia assisting Logan. With hardly a word said, they were on the same page the entire time. Dr. Bell might look young but you can tell, he has been around the block a few times. Thanks Logan and Julia!

Dr. Bell performed the second step of my root canal today and it went as well as the first, which was excellent. Dr. Bell is personal and professional and an expert at what he does. The equipment and technology he utilizes is clearly the best available as well. The experience was as good as it gets.

Dr. Kasper did my root canal and it was totally painless. He was friendly and professional and he explained the whole procedure to me. His office staff and assistants were extremely nice and friendly. I would highly recommend Dr. Kasper for anyone needing his expertise.

I am admittedly one of those who fear dental work to the point where just the thought of it creates terrible anxiety. Dr. Kasper and his staff treated me so well and assured me that I would not feel any pain on my initial root canal visit. In fact I felt absolutely no pain during the procedure. When I went back for the second treatment for the root canal I was as calm as sitting in a library. No anxiety or fear this time. While I hope to never see Dr. Kasper again, if I need dental work in the future this is where I am going to go.

I normally don’t write testimonials however, what I continue to experience with Dr. Logan Bell and his staff is a story to be told. Dr. Logan Bell puts you at ease instantly, educates you from beginning to end, provides all your options accordingly and answers all your questions. When the procedure is taking place you know exactly what to expect. And it doesn’t stop there, the extraordinary service continues on with his staff which makes you feel welcomed with each and every visit. I’ve had my share of dentists (endodonctic) over the years, however, no one to this date has exceeded my expectations like Dr. Logan Bell! Cheers to Dr. Logan Bell and his staff for their service and dedication to this practice. I HIGHLY recommend Dr. Logan Bell over and over again without reservation and his staff at Modern Endodontics—-you will NOT disappointed with the treatment or the experience!

Just finished the final step of my root canal with Dr. Bell today. I feel wonderful. He explained everything every step of the way and put me at ease. If I have any friends or family who ever need a root canal I will definitely refer them to this office!

I have literally never left a review of anything or anyone on the internet but I thought I should to help others like me. I am a GIANT GROWN WOMAN BABY about dental work. Straight-up phobia. So when I had to get a root canal - thud. My dentist assured me these guys were the best. She was not kidding. Dr. Bell and his assistant were so nice, calming, discussing everything that was going to happen and so utterly patient with my nonsense. And here's the thing - I really never felt a thing. It was unbelievable. I can't recommend them enough.
