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 Dr. Bell redo an old root canal. I was completely satisfied with the work done and found everyone professional and friendly. Dr. Bell was great at explaining everything step by step.

M. Jaros

Great Dr.- Great staff. My root canal was a little more complicated than most. Only 1 visit. Love It!

A. Walsh

A root canal is not exactly a pleasure, but mine was virtually painless. Dr. Bell explained everything, anticipated possible disturbances, and made it all work. Everybody was friendly and professional. I'm thoroughly satisfied.

Marvin Katilius-Boydstun

The office staff were great, Dr. Bell’s assistant was even better. Dr. Logan Bell was very thorough, a consummate professional, and explained the steps he took during the root canal and a follow-up visit. A root canal is not anyone’s way to spend a day but this doctor’s staff, assistant and he himself made this a painless procedure,

I came to Dr. Kasper for a root canal on a referral from my own dentist. Fantastic experience, professional, focused, informative, and really interesting to see and experience the high tech tools they use.

Mike Doyle

Root canal is usually synonymous with an unpleasant experience. Not that its a lot of fun, but Dr. Kasper was great! He explained everything to me and it was really painless. He made me feel confident and put me at ease. The entire staff in his office were really nice and great at explaining the procedure and what to expect. It had been years since I had a root canal and I remember it being somewhat painful...This was not at all that way. I highly recommend Modern Endodontics

Carl Giammarese

Had a root Canal done, expecting the worst and got the BEST! What a Professional Friendly atmosphere. Everyone is so friendly and helpful and Dr. K is very attentive and answer all my questions. Of course he waited for my mouth to be numb so I couldn't ask any..Only kidding, He is GREAT! Thank you, Thank you...

Kevin K

Dr. Ed, the assistants and the Modern Endodontics admin ladies are all real pros. My procedures were relatively painless and with very few post-procedure symptoms. Everyone was right on time and very organized. Thank you for making a potentially difficult experience very smooth.

All the glowing accolades have been expressed in previous testimonials so all I can say is "DITTO". Probably the least threatening experience of my life and I'm 86 so there's been many opportunities for something bad to happen. But this was a piece of cake. Dr. Bell and all the excellent staff you are HERO'S in my book.
