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.

This practice is extraordinary! I received treatment from Dr. Bell on 02-06-18, this was the same day I sought treatment. I went through the day in pain, received treatment and I am pain free. Dr. Bell, his assistant and front desk personnel were all very professional and courteous. This practice has, in my opinion, maintained a consistent and high level of service. It was quite sometime ago that I previously received treatment here and the same high standards remain. I have and will continue to recommend this practice to anyone needing treatment. Thanks!

Dr. Bell and his assistant were very professional, friendly and efficient. Dr. Bell explained everything that was going to happen and during the procedure. This was truly a painless root canal and I will come back if I ever need another one. Everything was done professionally and quickly. I was out of the office within the hour. Dr. Bell always made you feel you were dealing with a confident doctor who would handle any issues that may come up. It was a very pleasant experience.


I was very satisfied with the professional and pain-free dental services provided by Dr. Bell.

I had a lower front bridge for 29 years when it became loose. My dentist looked at it, placed a temporary bridge in place & suggested that I see Dr Bell. I had just scheduled back surgery, it was very important that this process be taken care of before surgery as I will not be able to tolerate sitting in a dental chair for several months after surgery. Every one was so accommodating & got me in quickly. Two root canals were retreated and the temporary bridge put back in place. A problem arose and the temporary fell off 2 times after the root canals were sealed. Dr. Bell got me in immediately and got the temporary back on within minutes. Monday is the oral surgery to help accommodate the final new bridge. After a healing time of 8-12 weeks we will be ready for the last step so that I can have my back surgery in March. To date everyone has worked like a well oiled machine. My heartfelt thanks to all involved.

A root canal is not something one eagerly anticipates.  However, Dr. Kasper’s expertise took much of the stress out of the experience.  His calm manner and willingness to take the time to thoroughly explain and listen to and respond to questions and concerns inspires trust.  In addition, the responsiveness and pleasant manner of the office personnel as well as the attention to detail in the office decor says a great deal about an emphasis on quality that also adds to a feeling of confidence on the part of the patient.


I have had a rather difficult tooth to deal with, and Dr. Kasper has shown great care and understanding. It has taken multiple visits and each time he has taken the time to explain what is going on and why. In addition, I must say that the root canal treatment has been virtually pain free. Hope I never need another, but if I do, it will be with Dr. Kasper. Highly recommended.

I received excellent treatment by Dr Kasper and his staff. He was great at explaining the problem and the treatment.
The atmosphere was calm and everyone was very kind and friendly. It did not seem rushed- I received the time that was needed to complete the treatment.
I would recommend Dr Kasper 100%!

First root canal so I was a big baby about the procedure and had many, many questions for Dr. Kasper. He took the time to answer all of them and never made me feel like I was taking up too much of his time. Very professional and very appreciated his thorough explanations.


I am a wimp when it comes to Dental procedures. I always hoped that the day would never come that I needed a root canal but it finally arrived! A two part one at that. Turned out that I never should have worried. Dr. Kasper was excellent and explained everything to me. His calm demeaner and excellence at what he does pulled me through. The office staff and everybody were great. I would recommend Modern Endodontics to anybody needing special work on their teeth.

Dr. Bell kept me informed of each procedure prior to performing the procedure. I felt quite comfortable throughout the entire procedure. Thank you Dr. Bell for your most kind consideration. I am very impressed with your professionalism while being kind and friendly. Your expertise contributed greatly to my physical and emotional comfort. Well done, Dr. Bell. The entire staff made me feel welcome. The interaction between Dr. Bell and his assistant during the procedure was fluid and flawless like a well tuned instrument. Thank you all.
