What is a root canal? How do you know if you need a root canal?
A root canal is a treatment used to save and/or repair a badly decayed tooth or an infected tooth. Inside of your tooth is a hard layer called dentin. Beneath the dentin layer is a soft tissue called the pulp. This contains blood vessels and nerves that help the root grow. After the tooth is fully developed, it can survive without the pulp as the tissue around the tooth helps nourish it.
When a root canal is performed, the pulp and nerve are removed from the tooth, and the inside of the tooth is filled after it is carefully disinfected. The tooth is filled and carefully sealed with a rubber-like material to prevent internal infection.
After the root canal is performed, usually a crown or filling is added for further protection. After everything is said and done, the tooth can further function like any other tooth!
