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 a root canal done, Dr. Kasper was very competent and professional. He explained all steps and did a very good job. I definitely recommend him.

I have had a root canal at another clinic years ago and remember an awful experience. Modern Endodontics was by far, SOOO much better. Dr. Kasper explained everything prior to and during the procedure, but to be honest, I trusted what he was doing and felt little anxiety, or pain. In fact, a couple hours after the procedure, I took one Advil to stay ahead of the pain after I felt the anesthetic wearing off, and I had absolutely no pain whatsoever! Dr. Kasper and the rest of the staff were super friendly. I would highly recommend their office and Dr. Kasper's services. Not that I want another root canal, but if I had to, I would not hesitate to contact Modern Endodontics again.

I have to admit that I was a little bit nervous when I learnt that I needed a root canal in one of my molars, years ago I had a bad experience with such procedure elsewhere. The reason why, I chose Modern Endodontics is because I've heard the reputation that they are the best specialists in the area. The appointment was made easy but the courteous receptionist, I was very happy to get an appointment to do my procedure within days. Dr. Kasper's assistant took me to get my X rays and my 3D Scan of the area, I was very impressed with the technology and offered there, after getting the images to Dr. Kasper screen Dr. Kasper himself explained me the whole process making sure all the areas post, during and prior to the surgery were covered. Dr Kasper went on numbing the area and giving the necessary time to the medicine to act making sure i was 100% pain free. During the surgery him and his assistant went way and beyond making sure I was comfortable, he kept me updated during each stage of the procedure. Before I realized the surgery was over and I left having absolutely no complications afterwards. Now I know why Dr.Kasper and the Modern Endodontics team have a pristine reputation. They are absolutely brilliant and I can't recommend them enough. Thank you Dr. Kasper and Endodontics Team. I really appreciate having a capable team like you in the area. I am extremely satisfied.


This was my first time getting a procedure by an endodontist. I had a great experience. Dr. Bell was awesome. He was very friendly and made sure I had no pain during my procedure. He showed me what he had done on the screen and explained it very well. The office was very clean. I would definitely refer modern endodontics to people.

From someone who grips the dentist chair so hard that I get white knuckled, I left their office with color in my hands. I didn't have an easy procedure (at least for me it wasn't easy) and I was terrified. But the entire staff and Dr Bell made me feel so confident that things would be go smoothly. When I left my first appointment I called me regular dentist to thank him for the referral. Dr Bell told me things that were going to happen and how long it would probably take. They will be my go to for any other work of that kind! Thank you Modern Endodontics for your kindness and professionalism!

I had my first root canal procedure done this morning by Dr. Bell and his team. I must say it was a fantastic experience. The entire staff was fantastic and Dr. Bell did a phenomenal job. I did not feel any discomfort and he kept me posted on exactly what to expect through the entire process. I would highly recommend Dr. Bell and his staff to anyone. Thanks for taking such good care of me.

John Kuhlman

Painless is the best way to describe my experience. The staff is very competent and welcoming. Dr. Bell explained everything prior to and during my first ever root canal. (Nothing personal but I hope it's my last) :) The procedure was absolutely painless and I would highly recommend Dr. Bell to anyone that needed his services. Thank You Dr. and your entire staff.

Dr. Bell did a root canal on me May 24, 2021. He was extremely explanatory, caring, and comforting during the entire process. I experienced no pain during or after the process. Dr. Bell is just exceptional; what more could I say.

I was very concerned having to get a root canal to say the least, but my experience with Modern Endodontics was terrific. Dr Kasper explained my options and everything thoroughly. The technology to see what I needed was great, and the entire process was very smooth. He is really good! I felt great the next day, no pain and the issue I had been dealing with went away. The staff, scheduling, payment options and working with my insurance could not have been better.

"...I'd rather have a root canal." This statement is often the butt end of a joke related to an uncomfortable task. Truth is I WOULD RATHER HAVE A ROOT CANAL so long as it is performed by this group. I had the pleasure of receiving my care from Dr. Bell who was engaging, informative and had a sense of humor. At no time did I feel any discomfort and actually fell asleep for a few minutes during the procedure. Additionally, the staff were pleasant and engaging as well...a sign they probably enjoy working there. That in itself speaks volumes. If I ever need another root canal , there is no other place I would go. My experience with this group and Dr. Bell has been the best dental experience I have ever had!
