Root Canal Procedure

A root canal is a dental procedure designed to treat infections or damage within the pulp (the innermost part of a tooth containing nerves and blood vessels). Despite its reputation, a root canal is a common and highly effective treatment that aims to save a severely damaged or infected tooth. 

What are Dental Crowns and How is the Procedure Performed?

Dental crowns are protective coverings placed over a tooth to restore its strength and appearance. The procedure involves:

  • Tooth preparation and shaping.
  • Impressions for crown fabrication.
  • Temporary crown placement.
  • Permanent crown placement after fabrication.

Can a Root Canal Be Done Through an Existing Crown?

Yes, a root canal can be performed through an existing crown. The dentist accesses the tooth's interior without removing the crown, making a small opening to perform the root canal procedure.

How Long Does a Root Canal Last with a Dental Crown?

A root canal, when done correctly with a well-fitted crown, can last a lifetime. Regular dental check-ups and good oral hygiene practices contribute to the longevity of the restoration.

Why Does Tooth Decay Happen after a Crown Is Placed to Protect It?

Tooth decay can occur under a crown due to various reasons, including bacteria infiltration, delayed crown placement after a root canal, damaged or worn-down crowns, and poor dental hygiene.

Reasons for a Root Canal on a Tooth with a Crown

1. Bacteria Trapped Under the Crown:

Bacteria entering the tooth structure under the crown can cause infection and necessitate a root canal.

2. Delay Placing a Crown after the Initial Tooth Canal:

Prolonged delay in placing a crown after a root canal leaves the tooth vulnerable to decay and may require further treatment.

3. Damaged or Worn Down Crown:

If the crown becomes damaged or worn, it may compromise the protection it provides, leading to the need for a root canal.

4. Poor Dental Hygiene:

Inadequate oral hygiene can contribute to decay around the crowned tooth, requiring intervention.

Signs Your Crowned Tooth Requires a Root Canal

  • Persistent pain or discomfort.
  • Sensitivity to hot or cold temperatures.
  • Swelling or tenderness in the gums.
  • Discoloration of the tooth.

If you experience any of these signs, prompt consultation with your dentist is essential for an accurate diagnosis and appropriate treatment. Early intervention can prevent further complications and preserve the health of your crowned tooth.
