Root canal refers to both the cavity (filled with pulp) or the replenishment of the pulp with an inert material. Read this HealthHearty article to know more about pain related with this.
The pain in the root canal actually refers to pain in the cavity of the tooth structure known as the root canal. We all know that the tooth is made up of three main parts – enamel, dentin, and pulp. The pulp is the innermost portion of the tooth that has nerves and blood vessels. The pulp of the tooth is present in the crown and the root of the tooth as well. Hence, when an infection, as is seen in cases of tooth decay, extends into this portion of the root, then it leads to pain in that region. However, most people mistakenly identify this type of pain with pain after or during the root canal treatment procedure which in fact is a misnomer.
Causes of Pain in the Root Canal
► Any kind of sudden trauma which might result in the loss of tooth structure and resulting exposure of the pulp can easily be an open invitation to an infection of the root canal which in turn will cause pain.
► Long standing cases of chronic pulpitis also lead to pain in the root canal which eventually necessitates root canal treatment.
► As is the common belief, there may be pain during or after the root canal treatment procedure.
► This pain is normally aggravated at night while sleeping or when the person lies down. The pain may also increase while chewing food, due to which the person may have loss of appetite.
► Swelling of the gums in the periapical region can be caused due to a tooth abscess. This swelling may also be visible externally if it is very large.
► Inability to open jaw completely is a symptom. Tooth discoloration may be seen.
► The person might even experience low-grade fever at times.
► If the infection is left untreated, it could spread to other parts of the head and neck region leading to other conditions like cellulitis , Ludwig’s angina etc.
Thus, pain can arise as a result of various root canal problems. It is important to deal with this condition on a priority basis, rather than waiting for matters to get worse and then blaming the dentist!
