Root Canal Therapy

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 die and 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 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 a dentist or 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.

Once the tooth is thoroughly cleaned, it will be sealed with either a permanent filling or, if additional appointments are needed, a temporary filling will be placed.

At the next appointment, usually a week later, the roots and the inside cavity of the tooth will be 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 visits will aid in the life of your root canal treatment.

I was traveling in the area from out of state and developed a toothache in route. A local colleague referred me to Dr St Germain for treatment. Dr St Germain determined I needed a root canal and although his appointment schedule was fully booked kindly moved other patients around to treat me. He and his staff were the most professional I have experienced anywhere including my dentist at home. I would highly recommend his office for their services and wish I live locally so I could use this practice regularly. Thanks again!!

Dr. St. Germain is very nice and explains things to his patients so they understand what is going on. He connects with them on a personal level which eases the "fear/anxiety" that one can have going to the dentist. MaryEllen is also great to talk to; whether you are on the phone or in the office, she will do anything she can to help you! I would defintiley reccomend Dr. St. Germain as your next dentist!!!

My sons' love the rides he gave them in his dental chair when they were younger and he always explains everything to them. They always leave his office with a smile, holding their new toothbrush or toy like a badge of honor. : ) Dr St. Germain always keeps up to date on all the latest dental techniques and studies which I love. He treats dental health with a "whole body" approach . He listens and really cares If you have dental anxiety now you won't after visiting Dr. St. Germain! His service and staff are top notch, and friendly too. Dr. St. Germain has helped me immensely, I had a few old filling which always gave me trouble, Dr St. Germain fixed them for me and I have never felt pain in those teeth ever again! My family and I Thank You Dr. St.

I greatly appreciate the care I receive from Dr. St. Germaine and his staff. I very much appreciate the attention staff pays to ensuring how much my insurance will cover, and work to make it work for me. I am a fairly new recipient of their care, but like how I am treated and care for.

Both my mother and I have attended Merrimack Valley Dental for the past 8 years and always have a quick and pain free experience. All of the hygienists remember me and act like one big family, while Doctor St. Germain makes every cleaning and procedure feel like a simple procedure while telling a story to distract you. They make a dentists appointment something you don't dread ahead of time!

I have enjoyed being a patient at Merrimack Valley Dental Care. The staff are consistently friendly and helpful. They truly care about my health and that of my family. My two young children are patients as well. They have their teeth cleaned and have even had teeth "pulled"/removed; all of which have been positive experiences for them and myself. Most recently, I took my children for their six month cleaning. I had messed up the times of their appointments. The staff at Merrimack Valley Dental Care accommodated us by staying later than they were scheduled to! I was extremely grateful for their flexibility.

I saw some negative reviews on this place and was shocked. I have been a customer who came from an AWFUL dentist that really really made it hard for me to go to the dentist. I needed a lot of work. We developed a plan and are executing! Fair prices, great people- I would and have recommended St. Germain and practice to friends and family. Went today for a cleaning and the experience hasn't changed from the first day I went.

I'm deeply afraid by dentists! I recently had a tooth extracted by DDS Albert St. Germain. He actually took the time to bring me in a calm state of mind. His gentail Staff of dental hygienist and office administration - I found my new dentistry!
Thank You Dr. St. Germain!

I hadn't been to the dentist in many, many years, and I was very nervous about the kind of work I might need when I first came to Dr. St. Germain and his staff. Right away, they were comforting and courteous. I had a cleaning within two weeks of my first visit, and a cavity filling several weeks later. Both procedures were done with skill and patience. There were no insurance hassles at all; the cleaning was 100% covered and the cavity filling had a reasonable co-pay. I would absolutely recommend "Dr. Saint" and his staff to anyone. They're extremely friendly and professional. I'll never enjoy a visit to the dentist, but at least I know I'm getting the best experience possible when I go to Merrimack Valley Dental Care.
