What is Root Canal

What is Root Canal Treatment

Root canal treatment is the treatment of the infected tooth, especially in the root of the tooth. It is one of the most common dental procedures recommended to the patients before going for extraction. An endodontist or general dentist performs this treatment based on the severity of the patient’s case. There are sure signs that indicate the requirement of root canal treatment. It includes tooth sensitivity towards cold or hot food items or beverages, sudden pain during chewing, swollen gums, cracked teeth, and deep decay in the teeth.

The root canal specialist follows a set of steps for the successful completion of the procedure.
Here are the root canal treatment steps:

In the first appointment of consultation,the dentist will take an X-ray to find the infected tooth’s current status.This will help in confirming the roots affected and the evaluation of the overall tooth. The dentist will injectlocal anesthesia before the step. This helps to reduce the possible root canal treatment pain, and patients can relax throughout the procedure.

Then,the dentist places the rubber dam,which is a sheet of rubber around the tooth that requires evaluation.This helps in achieving a dry environment,which aids in clear visibility.

The dentist creates a drill to access the full length of the tooth. The bacteria, pulp, and decayed tissues are cleaned thoroughly.Sodium hypochlorite or water is used for cleaning the root canals.

After cleaning, a medication is placed for the next few days. Once the tooth is cleaned, the dentist performs the sealing of the tooth. In some cases, the temporary filling is done to avoid food lodgement, depending on the patient’s case.

In the next appointment,gutta percha (rubber compound) and sealer paste is placed inside the cleaned root canal. The access hole is also filled successfully.Finally, the tooth is restored. In the case of severely damaged teeth, dental crowns are fixed above the restoration.The root canal treatment cost in India varies from 4,000 INR to 20,000 INR on average, depending on the severity of the infection, condition of the affected tooth, and dentist’s expertise. The average root canal recovery time is one to two weeks. Patients must understand that it is highly crucial to follow the post-operative care instructions that the dentist recommends after the treatment. Thus, root canal treatment proves beneficial for patients whowant to have their teeth saved for a significant time period.

Causes and Symptoms

  • Repeated Dental Procedures
  • Gum Disease
  • Cracked Tooth


  • Severe Toothache
  • Swollen Gums
  • Pimple on the Gums
  • Prolonged Sensitivity
  • Discoloration of the Tooth


In some cases, additional diagnostic tests may be performed to confirm the need for a root canal:

Pulp Testing: Assessing the vitality of the pulp by applying a cold stimulus to check for a normal response.

Electric Pulp Testing: Using a small electric current to measure nerve responsiveness.

CBCT (Cone Beam Computed Tomography): A 3D imaging technique that provides detailed images of the tooth and surrounding structures.

Transillumination: Directing light through the tooth to identify cracks or fractures.

While self-diagnosis is not a substitute for professional dental evaluation, individuals may observe certain signs and symptoms that could indicate the need for a root canal. These may include:Persistent Pain: Severe, throbbing pain that does not subside, especially when chewing or applying pressure to the tooth.Swelling: Swelling of the gums or face, indicating a possible infection.Pimple on the Gums: The presence of a pimple-like bump (dental abscess) on the gums near a painful tooth.Tooth Discoloration: Darkening or discoloration of the affected tooth.Prolonged Sensitivity: Increased sensitivity to hot or cold temperatures that lingers after the stimulus is removed.
Dentists are trained to assess oral health and diagnose the need for root canal treatment. The professional diagnosis typically involves:Clinical Examination: The dentist will visually inspect the affected tooth and surrounding area, looking for signs of infection, swelling, and tooth damage.X-rays: Dental X-rays provide a detailed view of the tooth's structure, allowing the dentist to identify issues in the pulp, such as infection or inflammation.Percussion Test: Gently tapping on the tooth to assess pain response, which can indicate the health of the tooth's nerve.

Risk & Complications

Cracked Tooth: The tooth may develop cracks or fractures over time, especially if it had substantial decay or damage before the root canal.

Tooth Discoloration: The treated tooth might change color, and while this is often minor, it can be a conce for some patients.
