When baby or adult teeth have large cavities that are either close to or into the nerve tissue, the tooth may require a pulpal therapy, such as a pulpotomy (removal of a portion of the infected nerve tissue leaving healthy tissue), pulpectomy (removal of entire nerve tissue from canals), or root canal therapy. Some signs and symptoms for possible pulpal therapy:
- An abscess (or pimple) on the gums.
- Sensitivity to hot and cold.
- Severe toothache pain.
- Sometimes no symptoms are present.
- Swelling and/or tenderness.
