Root Canals

Root Canals

A root canal is a dental procedure performed by our dentist in New York, NY, to treat infections within the tooth's pulp, the innermost part containing nerves and blood vessels. This treatment involves removing the infected or inflamed pulp, thoroughly cleaning and disinfecting the root canals, and then filling and sealing them to prevent further infection.

The benefits of a root canal are substantial: it alleviates severe pain and discomfort caused by infection, saves the natural tooth from extraction, maintains the tooth's function and appearance, and prevents the spread of infection to adjacent teeth and tissues. Ultimately, a root canal helps preserve oral health and avoid more extensive dental treatments.

Symptoms Indicating a Root Canal May Be Needed

  • Continuous or throbbing pain in a specific tooth, especially when chewing or applying pressure, may indicate an infection or inflammation of the pulp.
  • Heightened sensitivity to hot or cold temperatures, which persists even after the stimulus is removed, could signal pulp damage. 
  • A tooth that has become significantly darker or discolored compared to surrounding teeth may indicate pulp necrosis or death of the pulp tissue. 
  • Swelling or tenderness in the gums surrounding a specific tooth can indicate an infection spreading from the pulp to the surrounding tissues.
  • The development of a pimple-like bump on the gums near the affected tooth, which may release pus or blood, suggests the presence of an abscess or infection. 
  • If a previously stable tooth becomes loose, damage or infection within the tooth could be what is affecting its stability. 
  • A persistent bad taste or odor in the mouth, particularly around the affected tooth, may indicate the presence of a bacterial infection and decay. Contact us today to learn more!

The Root Canal Procedure

Examination and Diagnosis

The root canal procedure begins with a thorough examination performed by our dentist at L.E.S. Dental Group. It typically involves visual inspection, X-rays, and possibly other diagnostic tests to assess the extent of the infection and the condition of the tooth's structure.

Anesthesia Administration 

Once our dentist at L.E.S. Dental Group has determined that a root canal is necessary, local anesthesia is administered to numb the affected area. This ensures that you remain comfortable and pain-free throughout the procedure.

Access Opening 

With the area numbed, the dentist creates a small access hole in the tooth's crown to reach the infected pulp chamber and root canals. This step allows access to the infected tissue for removal.

Cleaning and Shaping 

The dentist carefully removes the infected or damaged pulp tissue from the pulp chamber and root canals using specialized instruments. The canals are then meticulously cleaned, shaped, and disinfected to eliminate any remaining bacteria or debris. 

Filling the Canals 

Once thoroughly cleaned and shaped, the canals are filled with a biocompatible material called gutta-percha. This filling material seals the canals to prevent recontamination and provides structural support to the tooth. 


After filling the canals, the access opening in the tooth's crown is sealed with a temporary filling. In a subsequent visit, a permanent restoration, such as a filling or crown, is placed to fully restore the tooth's function and aesthetics.

The Benefits of Root Canal Treatment 

Pain Relief 

Pain relief is one of the primary benefits of root canal treatment in New York, NY. By removing the infected or inflamed pulp tissue, which is often the source of severe toothaches, root canal therapy alleviates discomfort and restores comfort when chewing and biting.

Preservation of Natural Tooth 

Unlike tooth extraction, which removes the entire tooth, root canal treatment allows for preserving the natural tooth structure. This helps maintain proper alignment of surrounding teeth, prevents jawbone deterioration, and preserves facial aesthetics. 

Prevention of Further Infection

Root canal therapy removes bacteria and infected tissue from the inside of the tooth, effectively eliminating the source of infection. Sealing the cleaned root canals with filling material prevents further bacterial invasion and reduces the risk of reinfection. 

Functional Restoration 

After root canal treatment, the tooth is typically restored with a crown or filling, depending on the extent of the damage. This restores the tooth's strength, functionality, and appearance, allowing for normal biting and chewing.

Long-Term Durability 

With proper care and maintenance, a tooth that has undergone root canal treatment can remain functional and healthy for many years, often lasting a lifetime. Routine dental check-ups and good oral hygiene practices are essential for ensuring the long-term success of the treatment. 

Improved Oral Health 

Root canal treatment contributes to overall oral health by addressing underlying issues that could compromise the health of surrounding teeth and gums. By eliminating infection and restoring the tooth's integrity, the procedure promotes a healthier oral environment and reduces the likelihood of future dental problems. 

Cost-Effective Solution 

Root canal treatment is often a cost-effective alternative to tooth extraction followed by tooth replacement options like dental implants or bridges. By preserving the natural tooth, root canal treatment can help save on the long-term costs associated with tooth replacement procedures.
