If you are planning a root canal treatment in Kolkata and are unsure which method suits you best, this detailed comparison will help you make an informed decision based on facts, not fear.

What Is Root Canal Treatment?

What Is Root Canal Treatment?

Root canal treatment is performed when the inner pulp of a tooth becomes infected due to deep cavities, cracks, repeated dental procedures, or trauma. The pulp contains nerves and blood vessels, and once infected, it can cause severe pain, swelling, and abscess formation.

During a root canal procedure:

  • Removal of infected pulp
  • Cleaning and disinfection of canals
  • Sealing of canals
  • Restoration with a protective crown

Understanding Traditional Root Canal Treatment

Traditional root canal treatment uses manual or rotary instruments to clean infected root canals. Disinfecting solutions are used to eliminate bacteria before sealing the canals.

How Traditional RCT Is Performed

  • Local anesthesia administration
  • Access opening in the tooth
  • Removal of infected pulp
  • Cleaning with antibacterial solutions
  • Sealing of canals
  • Crown placement at a later stage

Traditional RCT remains an effective option, especially in straightforward cases, when performed by experienced dentists.

What Is Laser Root Canal Treatment?

Laser Root Canal Treatment uses advanced dental laser technology to disinfect the root canal system. Laser energy penetrates deep into microscopic canal spaces that conventional instruments may not fully reach.

Laser RCT offers:

  • Enhanced infection control
  • Minimal tissue damage
  • Reduced discomfort
  • Faster healing

Laser-assisted procedures are part of modern painless root canal treatment in Kolkata, especially for patients who are anxious or sensitive to pain.
