Technology & Science

What makes the Jambuvi DualRayâ„¢ Sonic Brush different from other toothbrushes?

The DualRayâ„¢ Sonic Brush doesn’t just clean — it heals. It combines blue and red LED light therapy with 38,000 sonic pulses per minute to reduce harmful bacteria, support gum healing, and restore balance to your oral microbiome — the foundation of total-body wellness.

How does blue light help oral health?

Blue LED light (405–470 nm) targets harmful bacteria like Streptococcus mutans — one of the main causes of plaque, bad breath, and decay.

 

Supported by Harvard and BMC Oral Health (2023) studies showing blue light kills cavity-causing bacteria without harming good microbes.

How does red light benefit my gums?

 Red LED light (630–660 nm) stimulates cellular energy (ATP), boosts collagen, and improves circulation — helping calm inflammation, ease sensitivity, and strengthen gum tissue.


Backed by multiple clinical trials in Photomedicine & Laser Surgery (2021) and Supportive Care in Cancer (2016).

Are the lights safe?

Yes. Both wavelengths are non-UV and non-ionizing, meaning they can’t burn, damage tissue, or affect DNA. They’re widely used in dental and dermatologic care and are safe for daily use by adults and teens.


Just avoid staring directly into the LEDs (especially blue light).

Can kids use the DualRayâ„¢ Brush?

Yes — with supervision.

  • Ages 6–12 → Use Soft or Red Light mode only.
  • Ages 13+ → Full use of Dual Light safe.
  • Under 5 → Not recommended. The light itself is harmless, but children’s eyes are more sensitive to direct blue LED exposure.

Is light therapy clinically proven?

  • Red Light: Proven to accelerate oral wound healing and reduce gum inflammation (Ribeiro et al., 2021).
  • Blue Light: Proven to reduce S. mutans bacteria — the key cause of cavities (Soukos et al., Harvard University, 2006).
  • Dual Light: Shows combined antibacterial + healing effects (Rajesh et al., 2022).
