Root Canal: What Is It and When Is It Done?

A root canal is a dental procedure that involves removing the pulp (the innermost soft tissue containing nerves and blood vessels) from a tooth when it becomes infected or damaged. The goal of a root canal is to save a tooth that would otherwise need to be extracted.

When is a Root Canal Done?

A root canal may be recommended in the following situations:

Infected Pulp:

When the pulp inside a tooth becomes infected due to deep decay, a cracked tooth, or repeated dental procedures, a root canal may be necessary. Bacteria can enter the pulp chamber, causing infection and inflammation.

Deep Decay:

When tooth decay progresses to the point where it reaches the pulp, a root canal may be needed. This is because the decay has compromised the pulp’s health, leading to infection and pain. To get help visit a Best Dentist in Karachi.

Trauma or Injury:

If a tooth has suffered trauma or injury, such as a fracture, a root canal may be required to address damage to the pulp.

Abscess or Swelling:

An abscess, which is a pocket of pus, can form at the root tip if the infection spreads to the surrounding tissues. In such cases, a root canal may be performed to eliminate the infection.

Severe Toothache:

Persistent and severe tooth pain, especially when chewing or applying pressure to the tooth, may indicate a problem with the pulp and may require a root canal.


The root canal procedure typically involves the following steps:

  • Diagnosis:

The dentist examines the tooth and may take X-rays to determine the extent of the infection or damage.

  • Anesthesia:

The affected tooth and the surrounding area are numbed with a local anesthetic to ensure the patient is comfortable during the procedure.

  • Access Opening:

The dentist creates an opening in the crown of the tooth to access the pulp chamber and root canals.

  • Cleaning and Shaping:

The infected or damaged pulp is removed, and the root canals are cleaned and shaped to remove any remaining debris.

  • Filling:

The cleaned root canals are filled with a material called gutta-percha to seal the space and prevent further infection.

  • Restoration:

A temporary or permanent filling is placed in the access opening, and in many cases, a dental crown is recommended to restore the tooth’s strength and functionality.

  • Aftercare:

After a root canal, it’s common to experience some discomfort for a few days, which can be managed with over-the-counter pain medications. It’s essential to follow any postoperative instructions provided by the dentist and attend any follow-up appointments.

Root canals are highly successful procedures, and they allow patients to retain their natural teeth even after significant damage or infection. If you experience persistent tooth pain or suspect a dental issue, it’s important to consult with a Best Dentist in Lahore for a thorough examination and appropriate treatment recommendations. Early intervention can help prevent the need for more extensive dental procedures.
