What Is Root Canal Treatment?

The Crown of a tooth is a three-layered structure namely – Enamel, Dentin & Pulp. If the tooth decay is limited to initial part or the first two layers, it can be corrected with Filling/ Restoration. In case the tooth decay reaches the third layer and causes inflammation or infection of pulp, root canal procedure is needed then.

Root Canal Treatment (RCT) is a procedure done when the tooth decay reaches the pulp (innermost layer of the tooth) causing inflammation. It is necessary to save the damaged tooth from extraction. This procedure is done by an Endodontist who is known as a Root Canal Specialist and the steps involves.

Why Does One Need To Undergo Root Canal Treatment?

Root Canal Treatment is done on a damaged or infected tooth. Infection could be due to a cracked or broken tooth, deep decay, gum diseases or maybe due to repeated dental treatment on that particular tooth. It becomes extremely important to get the Root Canal Treatment done as:

  • It stops the infection from spreading and also saves the tooth from extraction
  • RCT relieves the pain caused due to inflammation of teeth

What Is The Procedure For Root Canal Treatment?

Step 1 :

Very first step involves an X-ray which is taken to determine the extent and approach to infection.

Step 2 :

local anesthesia is administered before starting the treatment.

The next step is Cavity Preparation. A cavity is prepared, making sure all the infected tooth material or previous filling material is removed and a proper approach to inner-part of the tooth (pulp) is established.

Step 3 :

This is followed by disinfection and shaping of pulp canals. The infected pulp is removed completely, canals are shaped and cleaned. Thorough disinfection is achieved.

Step 4 :

Clean and disinfected canals are then sealed and filled with an inert filling material known as Gutta-Percha.

Step 5 :

Very last step is final restoration & crown. The crown portion of the tooth cavity is then restored with a filling, followed by a Cap/Crown cementation.

Post-Treatment Care For Root Canal Treatment

  • Do not put pressure on the tooth. Since there is no crown, the tooth is unprotected as a result, putting pressure can cause further damage to the tooth.
  • Avoid hard and crunchy food, its better to chew soft food until final restoration
  • Be careful while brushing. Don’t be too harsh while brushing.
  • Get a crown/cap as soon as possible as this will protect your tooth from further damage.
  • Visit your dentist if you face any issues or severe pain.
