Pulpitis is inflammation of dental pulp tissue. The pulp contains the blood vessels the nerves and connective tissue inside a tooth and provides the tooth’s blood and nutrients. Pulpitis is mainly caused by bacteria infection which itself is a secondary development of caries. It manifests itself in the form of a toothache. Pulpitis may be caused by dental caries that penetrate through the enamel and dentin to reach the pulp, or it may be a result of trauma, such as thermal insult from repeated dental procedures. Pulpitis can often create so much pressure on the tooth nerve that the individual will have trouble locating the source of the pain, confusing it with neighboring teeth, called referred pain.
