Endodontics (Root Canal)

Endodontics relates to maintaining the health of the pulp within the teeth.  It includes treating the damaged pulp, diagnosing problems in the pulp, capping (of the pulp), and root canal. It also includes post-endodontic treatment like crown and core restoration.

What is Root Canal Treatment?

Within the hard surface of the teeth lies a soft tissue called the pulp. This pulp contains vital parts like the nerves and connective tissue necessary for the health of the teeth. When the pulp becomes infected or inflamed, dentists undertake a root canal treatment. This process involves detaching the nerve of the tooth, thereby saving the tooth and removing pain.

How Is Root Canal Treatment Undertaken?

The entire root canal treatment usually takes around 2 sittings- the first appointment involves preparing the tooth for the treatment and allowing the root canal to heal. During the second appointment, the dentist fills the root and seals of the root canal. He also adds a crown to cover the opening. To explain the process in detail:
 

• The treatment begins when the patient is administered local anesthesia
• The dentist then isolates the infected tooth with a dental dam. This dam keeps the infected area dry, disinfected, and away from bacterial contamination.
• He then opens the infected area to remove/treat the infected pulp. The dentist also cleans and treats cracks if any.
• The doctor then reshapes the canals and fills the tooth with filling material and covers the tooth with a temporary covering.

When Is Root Canal Treatment Advised?

The dentist advises root canal treatment if:

• Intense toothache that does not subside with painkillers
• Intense pain while biting or chewing
• Swelling on the gum close to the infected teeth. When pressed this swelling may release blood
• Excruciating pain that radiates to the head and even ear.

Root Canal-Retreatment

 Sometimes the treated tooth may need re-treatment. This usually happens when the previous infection was not cleaned or sealed properly, or when the filling is broken causing reinfection.
