Laser Endodontics in New York City
Experience faster healing and deeper disinfection during root canal therapy with advanced laser-assisted technology.
Modern Root Canal Treatment with Precision, Safety, and Faster Healing
At Teeth By Keith, we believe that saving a tooth shouldn’t be painful, invasive, or unpredictable. That’s why we offer laser-assisted endodontic treatment a cutting-edge alternative to traditional root canals. Using Fotona’s LightWalker® laser system, we perform minimally invasive laser endodontics in NYC with reduced discomfort, faster healing, and superior cleanliness deep inside your tooth’s canal system.
Dr. Keith R. Marshall, DDS, brings nearly 20 years of laser experience to every case. Whether you’re dealing with a painful infection or a previously failed root canal, our advanced technology gives you a safer, more efficient solution.
What Is Laser Endodontics?
Laser endodontics uses photonic energy to clean and disinfect the complex root canal system with enhanced precision. At our office, we use SWEEPS® (Shockwave Enhanced Emission Photoacoustic Streaming) and PIPS® (Photon Induced Photoacoustic Streaming) techniques that generate powerful shockwaves to flush out bacteria, debris, and biofilm from even the tiniest branches of your tooth’s root structure.
These methods go beyond what traditional files and irrigants can reach, improving outcomes, reducing failure risk, and making the treatment much more comfortable.
Key Benefits of Laser Root Canal Therapy
- Minimally invasive — less drilling, no scraping
- Higher success rate by cleaning lateral canals and tubules
- Reduces the need for retreatments, extractions, or implants
- Lower risk of post-op pain and complications
- Preserves more natural tooth structure
- Supports regenerative endodontic approaches
- Enhances healing with Low Level Laser Therapy (LLLT)
Paired with Cone Beam 3D Imaging for diagnostic accuracy, this advanced technique is ideal for patients seeking long-term, minimally invasive tooth preservation.
What to Expect During Treatment
- Diagnosis & 3D Imaging – We evaluate your tooth with digital scans and CBCT imaging to map the internal structure.
- Laser Disinfection – Using the Fotona LightWalker® laser, we activate cleaning fluids and generate photoacoustic shockwaves to remove infected tissue.
- Sealing the Tooth – Once the canal system is disinfected, it’s filled and sealed for protection.
- Restoration – Many patients complete treatment with a same-day porcelain crown to restore function and aesthetics in one visit.
Ideal Candidates for Laser Endodontics
You may be a great candidate if:
- You’ve been diagnosed with pulp infection or inflammation

Is laser endodontic treatment painful?
No-pain patients often report less pain and faster healing than with traditional root canals. There’s no scraping or mechanical filing involved.
How successful is laser root canal therapy?
Laser treatment significantly improves success rates by eliminating bacteria from hard-to-reach areas. It also reduces the chance of reinfection and long-term complications.
Is laser endodontics safe?
Yes. SWEEPS® and PIPS® technologies are clinically proven, FDA-cleared, and safe for use on all patients.
