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.

Dr Cunningham was very helpful in explaining the root canal procedure from isolating the problem tooth to numbing the area and completion of the root canal. He was very good at keeping me calm and always checking on my comfort during the procedure, while explaining each step of the process and what I would be feeling. This was my first root canal and turned out much easier than anticipated, thanks to Dr Cunningham and his staff. Highly recommend Kevin and his entire team!

I have always had anxiety going to the dentist, periodontist or oral surgeon. This is the first time in my life that I had no pain and was put at ease. Thank you for such a positive experience. That root canal was not as bad as I anticipated.

Honestly, this place may have changed my absolute fear of dental work. I had to get a root canal retreated and I was TERRIFIED. I cried for two hours when I was told it had to happen. But they gave me proper medication and each person was incredibly friendly and made me feel right at home. They even gave me a blanket. I am notorious for not getting numb enough and I truly felt nothing. There weren't even any cringe sounds that I remember. The staff stepped into the lobby and informed my parents what was going on as it happened. I will go here as I need to for as long as possible; I cannot get over the incredible care and their ability to calm my anxious, panic-ridden heart. Thank you.
