What is a root canal?
A root canal is one of the most common dental procedures performed, well over 14 million every year. This simple treatment can save your natural teeth and prevent the need for dental implants or bridges.
At the center of your tooth is the pulp. Pulp is a collection of blood vessels that helps to build the surrounding tooth. Infection of the pulp can be caused by trauma to the tooth, deep decay, cracks, and chips, or repeated dental procedures. Symptoms of the infection can be identified as visible injury or swelling of the tooth, sensitivity to temperature, or pain in the tooth and gums.
If you experience any of these symptoms, your dentist will most likely recommend non-surgical treatment to eliminate the diseased pulp. This injured pulp is removed and the root canal system is thoroughly cleaned and sealed. Root canal therapy usually involves local anesthesia and may be completed in one or more visits depending on the treatment required. Success for this type of treatment occurs in about 90% of cases. If your tooth is not amenable to endodontic treatment or the chance of success is unfavorable, you will be informed at the time of consultation or when a complication becomes evident during or after treatment. Dr. Cunningham uses local anesthesia to eliminate discomfort. In addition, we will provide nitrous oxide analgesia, if indicated. You will be able to drive home after your treatment, and you probably will be comfortable returning to your normal routine.

Endodontic Presentation
To provide you with a better understanding of endodontic procedures, we have provided the following multimedia presentation. Many common questions pertaining to root canal therapy are discussed.
What happens after treatment?
When your root canal therapy has been completed, a record of your treatment will be sent to your restorative dentist. You should contact their office for a follow-up restoration within a few weeks of completion at our office. Your restorative dentist will decide on what type of restoration is necessary to protect your tooth. It is rare for endodontic patients to experience complications after routine endodontic treatment or microsurgery. If a problem does occur, however, we are available at all times to respond. To prevent further decay, continue to practice good dental hygiene.
How much will a root canal cost?
The cost associated with root canals can vary depending on factors such as the severity of damage to the affected tooth and which tooth is affected. In general, endodontic treatment is much less expensive than tooth removal and replacement with an artificial tooth.

I would never consider going to anyone else after seeing Dr. Cunningham. My husband and I have been to him several times and his chairside manner, lovely staff, thoughtful communication and education you receive regarding the treatment that is planned (and actually taking place), and patient sensitivity is beyond comparison. This practice sets the bar for all other dental professionals in our community (and probably country!)

I AM THE ABSOLUTE BIGGEST BABY WHEN IT COMES TO GOING TO THE DENTIST SO I WAS LESS THEN HAPPY TO LEARN I HAD TO GET A ROOT CANAL. WHEN THE BIG DAY FINALLY GOT HERE I WAS PLEASANTLY SURPRISED THAT IT WENT BY RATHER SMOOTHLY AND PAINLESSLY. DR CUNNINGHAM AND HIS STAFF DID AN EXCELLENT JOB OF EXPLAINING WHAT THE PROCEDURE CONSISTED OF AND CALMED MY NERVES AND MY ANXIETY. THE PROCEDURE WAS QUITE PAINLESS AND WENT BY RATHER SMOOTHLY. I WAS ABLE TO GO RIGHT BACK TO WORK AND ACCEPTED ALL OF THE SYMPATHY FROM MY CO WORKERS. I DIDN'T TELL THEM THAT IT WASN'T BAD AT ALL !! I HIGHLY RECOMMEND DR CUNNINGHAM AND HIS STAFF!!

The most comfortable root canal I've ever had. Wonderfully considerate and friendly staff. Dr. Cunningham made me feel completely relaxed probably resulting in not even having to take a single Tylenol after the procedure. A positive experience at every level.

I get a lot of anxiety going to the dentist. Dr. Cunningham has such a calm demeanor and explains everything step by step. He helped calm me down and feel very comfortable. In the past by other dentists, I have had shots in my mouth that about made me jump out of the chair, but whatever he did when he gave me the shots (even the ones in the roof of my mouth) I could barely tell he was giving me the shots. I have already recommended him to several of my friends and co-workers. If I need additional work done, I will definitely go back to Dr. Cunningham.

Procedure was quick and free of pain, a big help to deal with an infection near a tooth I had recently become aware of due to some swelling on the gum, to help deal with it before it progressed.

Great staff and treatment. From the moment you walk into the office you are met by friendly staff and while the care was quick I did not feel that I was just another appointment. Dr. Cunningham and Christy took the time to make sure that I was comfortable and knew exactly what was happening. So nice to be treated with such great care.

Dr. Cunningham was very kind, and he did excellent work. I was nervous for my first root canal, but he did a great job telling me what to expect, keeping me informed during the procedure, and administering the anesthesia. The pain was very minimal, and he and his assistant, were very good at keeping me comfortable and relaxed during the root canal. I would definitely recommend Dr. Cunningham to any one I know who is looking for an endodontist.
