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.

Today Dr. Bell finished a root canal on one of my molars. It was my first root canal, not something I was excited to experience. Every step of the way Dr. Bell was able to simply and clearly explain what he was doing, and what would happen next. Over the course of a couple visits I came to enjoy his company, certainly unexpected given the reason for being there. Today during the final work to complete the process I actually fell asleep twice, while he was working in my mouth. Dr. Bell is so smooth and efficient it is very easy to recommend him to anyone needing work in his areas of expertise.

Dr. Bell and his staff are fantastic. Dr. Bell is kind, empathetic and most importantly, an amazing endodontist. Who would have thought I needed 2 root canals in one week. He made me comfortable and calm. After the procedures there was minimal discomfort which I believe is because Dr. Bell is such a professional and talented endodontist.

Dr. Bell and assistants were great during my visits. He fully explained everything, made it as painless as possible and it was as stress free experience. They are the best.

Dr. Kasper and staff were extremely professional. All procedures were done quickly, everything was explained fully and little discomfort was experienced. The front desk is pleasant and accommodating. I can't say enough good things about Dr. Kasper and Modern Endodontics. Modern has my highest recommendation.

Chester Zaba

Can't thank Dr Bell enough for his kindness towards me during my recent procedure. Not only was he understanding about my horrible dental anxiety but he did everything he could to make it as painless as possible including allowing my husband in there as he isusually a calming force. Thank you so much Dr Bell and staff.

Judith Beckerdite

Can’t say enough about Dr. Bell and the staff, I suffer from dental anxiety, and they immediately put me at ease. Dr Bell explained the procedure thoroughly and was incredibly patient with me. It was a painless process and I would highly recommend them

Best experience with my Root Canal. From the initial phone conversation for an appointment, to the welcoming and clean office, I had a great visit. The staff was very caring and experienced. The X-ray and CT scan were taken with care. Dr. Bell really took the time to discuss the findings of the X-rays and treatment, and both Dr. Bell and his assistant were very gentle and excellent in treating my tooth. Truly a 5-star experience. Thank you so much!

You never think you're going to need to take your 15yr old child for a root canal. After an unfortunate softball accident knocked her front tooth out - I knew who to call. Having been a former patient myself, I knew she would be in good hands with Dr. Bell & Kaspar. They have a way of making a root canal "pleasant" explaining everything and making sure you are comfortable. The most professional, friendly & caring physicians around. I refer them over and over!
