BioLight Guardian Oral Red Light Therapy Device

Red light therapy has a well-documented body of research behind its oral health applications. The problem is that most devices are designed for skin and joints, not for the inside of the mouth. Holding a handheld device near your face does not get light to the gums, soft tissue, or the areas between teeth where the oral microbiome actually lives.

The Guardian is designed specifically for that. It delivers 630nm red and 850nm NIR directly into the oral cavity through a flexible BPA-free silicone mouthpiece that sits inside the mouth during each session. BioLight's patent-pending Dual LED technology means both wavelengths are emitted simultaneously throughout the full 16-minute automated session.

The device is waterproof and charges via magnetic USB with over 2.5 hours of battery life per charge. A storage case is included for hygienic storage between sessions.

If you want to apply red and NIR light therapy directly to the oral cavity as part of a daily oral health routine, the Guardian is built for that. Note: once opened and used, the Guardian cannot be returned due to hygiene and sanitary reasons.
