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 severe tooth pain for days in my upper molar. I wanted the tooth to be extracted just to get me out of my misery. Dr. Bell was able to get me in quickly to take a look. He gave me options on how to proceed to SAVE the tooth. He was very knowledgeable in explaining the process of what he was doing during the procedure which was quite relaxing. I had very minimal pain the next day. I would highly recommend him if you have severe tooth pain.

I saw Dr. Bell for a root canal on one of my front teeth. I was understandably nervous.."It's my front teeth!". Dr. and his staff put me at ease right away. Dr. Bell spent the time to explain what was going to happen, and let me know what to expect before each step. I have had good root canals before, but this was Pain Free !

Dr. Kasper and both of his assistants act as if they are doing a synchronized dance.  He'll ask for something and she'll immediately have it ready and the different instruments kept coming, very efficient.  It is a pleasure being in an office where people care and have personalities. Both visits have been stress-free.

I had my first ever root canal performed by Dr. Bell and his team. It was seriously one of the easiest dental procedures I’ve had. It was so pain free I think I fell asleep in the chair. Dr. Bell will explain everything in a way that is easy to understand and when he’s done he will actually walk you through the procedure with pictures of the work that was completed. Extremely thorough from start to finish. The rest of his team, especially his assistant, were incredibly efficient, did a great job keeping me comfortable, and clearly have the knowledge and chemistry to make for a great team. I’m 5 days post procedure and totally pain free, with minimal discomfort the couple days right after. Overall great experience. Thanks Dr. Bell and team!

Dr.Bell did my root canal today. It was a great experience, he and his assistant Maribel are every professional, warm and friendly. I was so nervous about root canal, but Dr.Bell communicated clearly to me what needed to be done and how, and explained everything in detail. I highly recommend this office and Dr.Bell to anyone who needs root canal.

This is, without a doubt, the most professional dentistry experience that I have ever had in my lifetime. A very courteous staff, incredibly experienced dentists and most modern equipment that I have ever seen. i came after my dentist could not complete my root canal and they worked overtime to finish the job. Amazing job!! Thank you.

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.
