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.

My dentist recommended Dr. Bell for a root canal and I could not be happier! He and his staff were great. He talked me through everything and very compassionate! They got me in quickly and I would highly recommend!

Went to the office on December 19, 2022 for root canal work on tooth 14. Dr. Bell did the work and I am very pleased. Work took about 2 hours and as I had been informed the tooth was a little sore for 3 days, now everything feels great. If endodontic work is required in the future, I would not hesitate to have work done at Modern Endodontics.

Today I had the pleasure - yes pleasure !- of being cared for by Dr. Bell and Cynthia for a root canal. The entire staff cannot be more professional, kind, courteous and compassionate. Dr. Bell explains everything in detail and in a manner that is easy to understand. His communication skills inspire great confidence. I can honestly say I had not an ounce of pain (I'm a pain weenie) and this evening have so little discomfort I only took ibuprofen to keep any inflammation at bay. 16 years ago, Dr. Kasper did a root canal on a different tooth - and my experience was identical. I have the greatest confidence in both Dr. Bell and Dr. Kasper, would recommend either of them for your needs.

I am very pleased with the care and professionalism of Dr. Kasper and his staff. I had a root canal performed and the procedure was explained to me ahead of time along with the expectations when completed. Some people in the medical profession will talk down to you; not so with this practice. I was treated with respect and felt comfortable throughout the process.

Dr. Bell and his staff are awesome!!! The entire experience from calling to schedule the appointment, to walking out after my root canal was completed was better than I could have imagined. Dr. Bell is skilled, professional, and his "chair-side manner" is top notch. He explains everything in detail, and the procedure itself was painless. I went to work afterward with no discomfort. Highest recommendation possible!!!

I recently saw Dr. Bell for a root canal due to my past dentist insisting that I get a crown on a cracked molar which quite honestly was not giving me any problems. The tooth began to cause considerable pain and Dr. Bell recommended a root canal which I consented to without much hesitation. He explained the procedure and went over the 3D X-rays he took with a considerable amount of patience. I did not feel rushed to have my questions answered nor did I feel pushed to have the procedure. Through no fault of his own, he had to go back into the tooth after my initial treatment to be sure the canals were cleaned thoroughly. His office also has a special machine called a wave that further cleans out the canals. He was patient with me, since I am prone to complications due to inflammation in whatever I have done to my body. His fee covered all the repeat procedures he did on me and he waited to complete the full procedure until he felt I was satisfied. I just retired from working in the healthcare field, and I can not say enough in his praise. I recommend him without any hesitation for root canals. The medical/dental fields need more professionals like Dr. Bell who truly care about their patients and outcome.

Had an emergency root canal, Dr Bell and staff went over the top to explain everything in detail. They completed the root canal in less than 2 hours. Was as pleasant as a root canal could be. Would highly reccomend them, thank you.

In the two visits I had with Dr. Bell, I was treated very professionally by Dr. Bell and his staff. The procedure was painless and could not have gone better. I have already recommended Dr. Bell to a friend, and with a little luck, will never have to return for more work.

Dr. Bell was amazing--I've had several root canals done on my teeth--He was kind, very guiding on the procedure with every detail- best part.. NO PAIN. Even the novocaine which is the worst part of any dental work was painless. I would recommend Dr. Bell to anyone needing a root canal. I wish he could do all my dental work ...

I wondered why my dentist sent me to Dr Kaspar as a referral for a possible root canal, but now I know. Dr Kaspar's skills in all things "root canal" is evident from the first meeting. I cannot emphasize enough the value of expertise in this area. Dr Kaspar is a consummate professional.
