Your teeth contain several layers: enamel, dentin and the inner layer called the pulp that contains what is more commonly referred to as the “nerve” of the tooth. Each pulp chamber branches off; forming canals that lead toward the root tip. These infamous canals provide a means for the tooth to absorb what it needs from the blood supply. A deep cavity, traumatic injury, or tooth fracture can make the canal susceptible to bacterial infection, which can destroy the pulp and create pressure within the tooth. This can cause severe pain and may initiate tooth loss. If you see a dentist in the earliest stages of this condition, the tooth may be saved with a root canal.

As with most procedures, we recommend the use of local anesthesia. Following the procedure, you may experience temporary irritation of the tissues that surround the tooth. This is usually so slight that it can be controlled with an over the counter anti-inflammatory. Should you develop any severe swelling, or increasing pain, you should contact your dentist at once.
