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.

This was my first root canal in about 35 years and was as pleasant an experience as a root canal can be. All steps in the procedure were clearly described in advance and methods of communication when talking was impossible were well-defined. I arrived a few minutes early for the appointment and was called in as soon as I finished my medical history. X-rays were taken right away and consultation was done immediately following the x-rays. The whole process, including waiting for the anesthetic to take effect, was done efficiently and I was in and out of the office in less than an hour.

I have never had a totally pain free root canal until now. I hope I never need another one but if I do you can be sure that it will be with this office. Everyone was so nice and my kind of friendly!

GREAT staff;;;;friendly & professional. EXTREMELY helpful with insurance issues. Literally PAINLESS procedure ....I was VERY impressed with Dr Cunnungham. He explained the procedure prior to starting and proceded as stated. Upon completion he provided a script for pain meds which was I never needed/used. For someone who DOES NOT cherich the thought of going to the dentist (who does) Dr Cunnungham puts you at ease and is very "gentle" throughout the procedure. One cannot go wrong selecting him as their endodonist

Dr. Cunningham explained everything he was going to do and checked to make sure I was doing ok during the procedure. A root canal is not fun for anyone but, he made it the best experience it could be.

What a wonderful experience for a root canal. The doctor was so warm and kind and explained the procedure to a "t". The staff also was very kind. It is an uncomfortable place to be (a root canal setting) but they sure did their best to make it a great experience. Thank you to all, esp. Dr. Cunningham!

I must say he is fantastic. The entire staff was so professional. I was in and out with very little wait time. I had a root canal many years ago that was the worse excruciating pain ever. So going into my appointment I was extremely filled with anxiety and nervousness at the thought of getting a shot in the roof of my mouth for an upper root canal. Not at anytime during my shots or the entire procedure did I feel anything. This guys got it down and I will go no where else for any future root canals I may need. Thank you to you and your entire staff Dr. Cunningham.

I was cried myself to sleep for two days, had to take pain medicine to even get through the day. I came in to get my tooth evaluated for a root canal. After Dr. Cunningham evaluated me he determined I needed a root canal. He knew that I had a new born at night and a 5”6 year old daughter. Dr Cunningham told me to come in that day to do the root canal instead of sending me home (1 hour away). Dr. Cunningham is by far the best Dr. I’ve ever seen. I am so grateful that I was referred to his office. (If you read this, thank you for everything you did for me. Sometimes the little things mean the most to a person!!)

I had an excellent experience with Dr. Cunningham and his staff ! I was extremely nervous to have another root canal done and was very happy with the process and the outcome. They made sure I was prepared and well informed for the procedure as well was comfortable during the procedure. I especially appreciated the follow up call the next day to check on how I was feeling post procedure. I would highly recommend his office and plan to use them for any future dental needs.
