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 am one "nervous Nellie" when it comes to dental work, but I experienced NO PAIN or discomfort AT ALL! I got worked up for nothing! Dr Cunningham told me about every step he was making so there were no surprises and his assistant was superb!! It was like she could read his mind and had every instrument in his hand instantly. They work together like a well-oiled machine. If you are dental hesitant...(or just a big baby like me), this is definitely the place to go!!

I never had a root canal before, and I was nervous about it. Dr. Cunningham came in and introduced himself, and I started feeling better. His staff was fantastic and knowledgeable. They explained the procedure and what was going to happen. The staff showed me the instruments they would be using, and explained their purpose. They had a bite block to keep my mouth open, and I surprisingly preferred it, as opposed to just having to keep my mouth open. I was surprised how quick it was. 25-30 minutes later, I was out and ready to clock back in to the office. Thank you Dr. Cunningham!
