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.

Patients should have no fear of this procedure, most especially if a patient of Dr. Cunningham. He puts you at ease, explaining the procedure you are about to receive and giving you confidence that he knows what he is doing and everything is going to be fine. His assistant is well trained and they work as a team. She's always anxious to make sure you are comfortable (and warm!) and a simple wave of your hand will quickly get her attention if you feel you need help.

Having never only having one other good (pain free) experience with severe procedures at dentists, this experience was bar none the best dental experience I’ve ever had. Dr. Cunningham and his staff are very patient, thorough, and professional. Needing a root canal due to a chipped molar, I elected for conscious sedation in lieu of previously poor and heavily painful root canal/ crown experiences in the past (5+ times) and the anxiety that I carry with dental procedures as a result. It was incredibly surprising that I was fully conscious and did not even feel the numbing shots not to mention any of the procedure whatsoever. Highly recommend any serious dental procedure with Dr. Cunningham. It is very apparent he genuinely cares about the patient throughout the entire process to ensure the utmost comfort. A+++ service!

Dr Kevin is a superb Endodontists. He immediately puts you at ease, explains in detail the procedure and anesthetizes the area painlessly. He explains as he goes along and makes sure that you are kept as comfortable as possible throughout the procedure. He works quickly and efficiently. Virtually a pain free no stress experience. And there is a followup the following day to make sure you are doing fine. I can't recommend anyone more enthusiastically than Dr Cunningham and his staff.

This appointment was very quick and painless. Everything was explained to me beforehand. Very nice people all around. I asked Dr. Cunningham to jab the needle in my neck and numb my whole head but as it turns out this wasn’t necessary. VERY painless. Excellent experience!

Dr Cunningham and his staff were very easy to work with and made it easy to be their patient. I wouldn’t go so far as to say it was a pleasant experience to have a root canal but Dr. Cunningham and his staff made it a better experience than I expected. I would not hesitate to recommend them.
