Root Canal
A root canal is a dental procedure designed to treat infection or damage within the pulp of a tooth. The pulp is the innermost part of the tooth, containing nerves and blood vessels. When the pulp becomes infected or inflammed due to deep decay, gum diseases, apical infections,or trauma, a root canal is necessary to save the tooth and alleviate pain.

Key Steps in a Root Canal Procedure
1. Diagnosis and Assessment
A dentist performs a thorough examination, which may include X-rays, to diagnose the extent of the infection or damage to the tooth pulp. Symptoms indicating the need for a root canal include severe toothache, sensitivity to hot, swelling, and abscess formation.
2. Local Anesthesia
Before the procedure begins, the dentist administers local anesthesia to numb the affected area, ensuring the patient remains comfortable and pain-free throughout the treatment.
3. Access Opening
A dentist creates a small access opening in the crown of the tooth to reach the pulp chamber and canals of the root of the tooth.
4. Pulp Removal
Using specialized instruments, a dentist removes the infected or damaged pulp from the pulp chamber and root canals.
5. Cleaning and Disinfection
The canals of the tooth are thoroughly cleaned and disinfected to remove any remaining bacteria and debris. This step is crucial to prevent future infections.
6. Filling and Sealing
Once the root canals are cleaned and disinfected, they are filled with a biocompatible material called gutta-percha. The access opening is then sealed with a temporary or permanent filling to protect the tooth from contamination.
7. Restoration
In many cases, a crown is placed over the treated tooth to restore its strength, function, and appearance. The crown protects the tooth from fractures and further damage.
Benefits of a Root Canal
Pain Relief
Root canals provide significant relief from pain and discomfort caused by pulp infections or abscesses.
Tooth Preservation
The procedure allows for the preservation of the natural tooth, preventing the need for extraction and maintaining the integrity of the dental arch.
Improved Oral Health
Removing the infected pulp and sealing the root canals prevent the spread of infection to neighbouring teeth and supporting structures.
Restored Function
The treated tooth can function normally, allowing for proper chewing and speaking without discomfort.
Considerations for a Root Canal
Cost
The cost of a root canal varies depending on factors such as the complexity of the case and the location of the tooth. Discussing cost and insurance coverage with your dentist is essential.
Duration
Root canal procedures typically take 2-3 visits to complete. The restoration process may require additional appointments if a crown is needed.
Post-Procedure Care
After a root canal, maintaining good oral hygiene, attending regular dental check-ups, and avoiding chewing on the treated tooth until it is fully restored are important for long-term success.
