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.

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.

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!

This office is professional! The folks I met were outstanding. Went out of their way to make you feel comfortable. Dr Kasper explained what he was going to do and what he could not do if he ran into problems like a broken tooth. At the end of the procedure he answered questions and explained what he had done along with sharing the exrays. They were so good it almost makes you want to go back and have another root canal but not quite!!!!!

Alex McClement

Not having had a root canal procedure in over 20 years, I was not looking forward to having another. However, many things have changed as Dr. Bell demonstrated. I was quite amazed at the improvements of all aspects of the operation. A soothing staff to assuage jumpy nerves, 3D Xrays, consultation, anesthesia, more of a tooth saving drilling approach and much less time in the chair. I'm not saying it was a picnic but if you need this work done, you should definitely consider Dr. Bell and his team. 5 stars!

Ed Geberbauer

I had an excellent experience with Dr. Bell yesterday. I needed a root canal and he thoroughly explained everything beforehand. During the procedure, I was comfortable and he continued to tell me what was happening. His entire staff was warm, friendly and efficient. I would definitely return if I needed to.

Lori V

Dr. Kasper, and his staff, were excellent. I felt as comfortable as one can possibly feel when getting a root canal. Dr. Kasper inspired confidence, competence, and compassion. I did not have pain during the procedure or after the procedure. Yes, uncomfortable during the procedure-to be expected. Two Tylenols-6 hours apart, and the next day it was as if I never had a root canal. Thanks to Dr. Kasper and his friendly staff.
