Root Canal Therapy

Root canal therapy is needed when the nerve of a tooth is affected by decay or infection.  In order to save the tooth, the pulp (the living tissue inside the tooth), nerves, bacteria, and any decay are removed and the resulting space is filled with special, medicated, dental materials, which restore the tooth to its full function.

Having a root canal done on a tooth is the treatment of choice to save a tooth that otherwise would have to be removed.  Many patients believe that removing a tooth that has problems is the solution, but what is not realized is that extracting (pulling) a tooth will ultimately be more costly and cause significant problems for adjacent teeth.

Root canal treatment is highly successful and usually lasts a lifetime, although on occasion, a tooth will have to be retreated or removed due to new infections.

Signs and symptoms for possible root canal therapy:

  • An abscess (or pimple) on the gums.
  • Sensitivity to hot and cold.
  • Severe toothache pain.
  • Sometimes no symptoms are present.
  • Swelling and/or tenderness.

Reasons for root canal therapy:

  • Decay has reached the tooth pulp (the living tissue inside the tooth).
  • Infection or abscess have developed inside the tooth or at the root tip.
  • Injury or trauma to the tooth.

What does root canal therapy involve?

A root canal procedure requires one or more appointments and can be performed by Dr. Dahm or in some cases, referred to an endodontist (a root canal specialist).

While the tooth is numb, a rubber dam (a sheet of rubber) will be placed around the tooth to keep it dry and free of saliva.  An access opening is made on top of the tooth and a series of root canal files are placed into the opening, one at a time, removing the pulp, nerve tissue, and bacteria.  If tooth decay is present, it will also be removed with special dental instruments.

The roots and the inside cavity of the tooth are then filled and sealed with special dental materials.  A filling will be placed to cover the opening on top of the tooth.  In addition, all teeth that have root canal treatment should have a crown (cap) placed.  This will protect the tooth and prevent it from breaking, and restore it to its full function.

After treatment, your tooth may still be sensitive, but this will subside as the inflammation diminishes and the tooth has healed.

You will be given care instructions after each appointment.  Good oral hygiene practices and regular dental health visits will aid in the life of your root canal treatment.

After many years of being self-conscious about my smile due to an overbite and overlapping teeth, I decided to have a consult about having braces (preferably Invisalign). Due to all the correction needed, wire braces were my only option. After 5 years of various correction procedures I am now proud of my smile. Dr. Jeff and the staff were always prompt and very encouraging during each visit.

I had an appointment this morning for a crown prep. I was seated a few minutes before my actual appointment time. I was seen immediately by the assistant who prepped me for my local anesthetic. The anesthetic was given gently and painlessly. When I was thoroughly numb the procedure was started and finished in a shorter time than I had thought it might be. I was happy with all the services I received. Everyone from office staff to those assisting and performing the services were courteous and efficient. Dr. Dahm was his usual friendly professional self. I would recommend this dental practice to anyone needing dental care.

I know, through my own work experience, that working with the public can be trying at times, and sometimes it is difficult not to fall into a "negative" mode, which really does none of us any good. I am not sure whether a "negative" atmosphere shows its face when dealing with people, as much as a "positive" atmosphere does, or not. I am inclined to think not, but anyway, I would like to say that I am proud of everyone in your office, for creating and keeping that "positive" atmosphere, for all of us patients, because it truly does make a difference in the way we feel while we are there, and when we leave the office. I don't ever remember giggling several times during a dentist appointment, but couldn't help myself yesterday morning, as Dr. Dahm moved through the office, greeting, reassuring, and caring for people. The girls who helped me through the x-rays, molds, and other necessary procedures were awesome, as well! "Good Job", "You're doing great", etc., while in a place where most people are a little uncomfortable, at best, is so nice to hear. And, when I was confused about just where in my mouth my filling would go, the girls were so kind in explaining that they really were going to work on the correct tooth. LOL! I am running on here, but I think too often in business, the main feedback that people get, is the negative stuff. I have always tried to counter that, by letting people know when I really do appreciate what they have done "for" me, instead of "to" me, and I will be the first to admit that trust does not always come easy for me - just the way I am. And, I feel that an establishment's "true colors" show in instances like I had yesterday, when I needed some reassurance that everything was okay. I am so appreciative of the way everyone handled that (sorry that I took up precious time), but now I know, that if/when I truly do need help, it will be there, and given in a kind and understanding manner. That means a LOT to me! So, in closing, in the middle of the night, during my usual "awake" time, I just kept thinking WOW! I just don't know of a better way to express my feelings! And, of course, THANK YOU to everyone in that office, because it takes every person in an environment like that to maintain a caring and positive atmosphere! I notice and I appreciate all of it, and I would recommend anyone I know to become a patient there!
