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 had a a previous root canal by my dentist and had to go back for severe infection and another root canal and lance of my upper gums to drain infection and they sealed it leaving a isthmus that was infected, I then went to Mr Cunningham who found it and corrected it with yet another root canal. Needless to say his professionalism solved a very expensive and long term time spent in severe pain. Very personable and professional in every way!

What a relief that I could get my root canal scheduled the day after I called! In and out of the office in under an hour. No pain during the procedure at all and I appreciated all of the mouth protection to make the procedure as comfortable as possible. I had minimal soreness for the next 24-hours. Thank you for the safe and complete procedure. I highly recommend this practice!

I was extremely anxious to get the root canal after being in so much pain left by my dentist after my filling and everyone was amazing and so nice. Birdie really helped me out with my concerns regarding my insurance. I left feeling like a weight has been lifted off my shoulders after weeks of pain. Thank you guys so much! Sorry if I was annoying and asking so many questions lol
