The standard Guardian handles oral red and NIR light therapy. But if you also want teeth whitening, you are looking at a second device, a second charging routine, and a second daily step. That friction adds up.

The Guardian+ consolidates both into one mouthpiece. It adds 460nm blue light to the existing 630nm red and 850nm NIR configuration, with blue LEDs in the top row and red and NIR LEDs in the bottom row. Three light settings let you run blue only for whitening, red and NIR only for oral health, or all three together. Three 2 oz whitening gel pens using 36% carbamide peroxide are included.

An automated 5-minute timer manages each half of the mouth independently, run the first 5 minutes, rotate 180 degrees, run the second 5 minutes. The flexible BPA-free silicone mouthpiece is waterproof and charges via magnetic USB with over 2.5 hours of battery life per charge.

If you want teeth whitening and oral light therapy in a single daily routine without managing two devices, the Guardian+ is built for that. Note: once opened and used, the Guardian+ cannot be returned due to hygiene and sanitary reasons.

Wavelengths: 460nm blue, 630nm red, 850nm near-infrared
Light irradiance at 0": blue 2.2 mW/cm2, red and NIR 1.2 mW/cm2

Ensure the device is fully charged before your session.
For teeth whitening: apply whitening gel to teeth before inserting the mouthpiece.
Select your light setting, blue only for whitening, red and NIR only for oral health, or combo for both.
Insert the mouthpiece and power on. The 5-minute timer starts automatically.
After the first 5 minutes, rotate the device 180 degrees to treat the opposite row of teeth for another 5 minutes.
Use once or twice daily. Clean and dry the mouthpiece after each session and store in the included case.
Once opened and used, the Guardian+ cannot be returned for hygiene and sanitary reasons.

The Guardian+ is designed for users who want both teeth whitening and oral light therapy from one device. The combination of blue (460nm), red (630nm), and NIR (850nm) wavelengths in a single mouthpiece covers whitening, antibacterial, and oral tissue support applications in the same daily routine.

Three wavelengths in one device, blue (460nm), red (630nm), and NIR (850nm)
Three light settings for whitening-only, oral health-only, or combined sessions
Flexible BPA-free silicone mouthpiece for comfortable, waterproof daily use
Automated 5-minute timer for consistent, hands-off sessions
