Dr. Kalchthaler,

I very much appreciate you getting me in so quickly and fixing my tooth. I had been in pain for 4 days and you did a great job on the root canal, no pain then or now. 

Thank you,


Jeffrey M.

The experience in your office was fantastic.  Everyone was helpful and pleasant.  I can say that I do not like having a root canal, but the experience there makes it much better.  I appreciate the professionalism of each and every person in the office.  Dr. Durand is wonderful and very courteous and professional.  His calm and quiet demeanor puts you at ease.  The flowers are a nice touch too!

To have a root canal and admit it was a good experience is really saying something!!  Dr. Durand and his ENTIRE staff were wonderful.  So professional, caring and kind.  I can't say enough good things about all of you.  I have already recommended you to friends and family if they should need you.

Dr. K and staff,

You make the world a better place for all those whose lives you touch. Hope all the good care you give to others comes back to you. Thanks for the great care during my recent root canal. A special thanks for seeing for so quickly.

I have been directed to Dr. Durand for possible root canal procedures twice by my dentist, Dr. Spencer. The first time I was surprised and pleased when Dr. Durand told me he felt after my exam. He felt I did not require a root canal. My friends said that in their experience if you went for an exam you were always told by the doctors they saw that the procedure was necessary! Apparently, Dr. Durand is to be considered the exception who truly puts the patients needs first! This time I was having considerable pain and after the exam he sat down with me and explained that he felt it would be in my best interests. All of you and the doctor were very professional, efficient and kind. I had heard so many horror stories about the procedure that I was very nervous but everyone made sure to make me comfortable and at ease. This evening even though I just had it done this afternoon I feel less pain than I did before it was done! And just in case I was having trouble the doctor just called me to ask if everything was OK. I am so grateful for the exceptional care and concern I don't know how to explain it. Thanks so much and God bless you all.

I wanted to thank you and your staff for your exemplary professionalism and care.

This was my second procedure in your office, and I'm again impressed with Foothills Endo.

My wife has worked in the dental community for well over 3 decades, and I'm somewhat familar with the dynamics of various practices. I have nothing but the highest praise for you and your staff!

By the way, my recovery has been speedy; so far, so good.

My very best,

What is an Endodontist and what do they do?

Endodontists are dentists who specialize in maintaining teeth through endodontic therapy -- procedures, involving the soft inner tissue of the teeth, called the pulp.  All dentists are trained in diagnosis and endodontic therapy, however, some teeth can be especially difficult to diagnose and treat.  That’s why you may have been referred to an endodontic specialist.

In addition to dental school, endodontists receive two or more years of advanced education in this kind of treatment. They study root canal techniques and procedures in greater depth to allow diagnosis and treatment of more difficult cases. Endodontists also have their offices set up with specialized equipment and instruments specific to performing endodontic therapy.  For these reasons, many dentists choose to refer their patients to endodontists.

What happens during endodontic treatment? or What is a Root Canal?

A local anesthetic will be given.  A sheet barrier will be placed around the tooth to isolate it, hence keeping your mouth free of all tooth dust and debris.  Also this will protect your tongue from our instruments.  Depending upon what we find inside your tooth, treatment will take one or more visits of 1 - 3 hours each.  In the course of treatment the pulp is removed from the roots and is replaced with a plastic filling material.  If you were to think of each root as being like a pencil, the root canal will result in the led being replaced with plastic and with minimal removal of the wood.  To get the most complete pulp tissue removal with the least weakening of the tooth, we will utilize a clinical operating microscope.

There are, of course, no guarantees.  Root canal therapy has a very high degree of success, up to 90%.   We will discuss with you the chances of success before any endodontic procedure to help you make an informed decision. 

Upon completion of the root canal a healing filling is placed.  After the healing period your general dentist will evaluate the tooth and the previous fillings or crown and place the ideal final restoration.  With rare exception, the ideal restoration is a crown.  In cases where the tooth already has an existing crown that was not destroyed during the root canal, a filling rather than a new crown may be possible.  We take every effort to preserve existing crowns, but sometimes crown destruction is unavoidable.


Occasionally a tooth that has undergone endodontic treatment fails to heal or pain continues despite therapy. Although rare, sometimes a tooth initially responds to root canal therapy but becomes painful or diseased months or years later. When either of these situations occur, the tooth often can be maintained with a second endodontic treatment.

Will I need to return to your office for additional visits?

Once endodontic therapy is completed your tooth should be examined periodically to check for proper healing, usually every 6 - 12 months.  This allows us to make sure the tooth has healed or is healing properly.  In some cases this can be done by your general dentist and in other cases we may need to see you.
