Root canal treatment saves the tooth when it gets infected or injured. During the treatment, the pulp tissue of the tooth is removed.
Infection of the tooth: In this case, an untreated decay of the tooth may lead to inflammation and infection of the pulp. This can be dangerous when the infection spreads to the surrounding bony structures.
Trauma to the tooth: Any kind of trauma to the tooth will evoke a pulpal reaction. In many cases, the trauma might have occurred years back to be manifested as a new case of infection. Chronic irritation and trauma can also lead to the infection of the pulp.
Whatever be the reason for the infection, prompt treatment and filling of the root canals is essential to control the infection and bring the tooth back to the normal state. It is almost impossible to retain such an infected tooth without doing root canal treatment, and the other option is to extract the affected tooth and get it replaced.
You can seek immediate dental care if you have any the following symptoms:
Spontaneous pain of the tooth or pain in response to hot stimulus that does not subside. This can be present with or without a swelling in relation to the affected tooth/teeth.
Discoloration of teeth or fractured teeth

Root Canal Treatment can be done in a single visit or multiple visits. However, the dentist will decide the number of visits depending on a particular case. Anatomic variations in the roots, curved canals and severe infections are big challenges to the dentist who performs the root canal treatment.
Root canal treatment, contrary to the belief of many, is an absolutely painless procedure. During the initial visit, your dentist will administer a local anesthetic to make the area numb and to ensure a painless procedure. After that, the canals are accessed and the infected tissue is removed using the root canal instruments. The canals are cleaned and made sterile using various medicaments and irrigating solutions.
After the canal is adequately shaped to receive the filling material, the filling material is placed into the canals to prevent future infection. The process of root canal filling seals the canal from contamination. Once the canals are filled and the tooth is asymptomatic, a crown is placed after preparation of the treated tooth. This is to strengthen the already weakened tooth structure. Apart from that, the normal color of the tooth is restored by placing such crowns.
Root canal treatment is also done for primary teeth which cannot be treated by using the normal restorative techniques. Doing such treatment for the primary teeth will keep the arch space as such and maintain it till the permanent successors are erupted.
Early restoration of the decayed teeth and periodic check up can prevent the infection of the pulp tissue.
