Oral Red Light Therapy Devices

A mouthpiece (BioLight Guardian, Guardian+) is a flexible BPA-free tray lined with LEDs. You bite down, start the timer and the LEDs sit against the gums and teeth on both arches at once. Sessions are 5 to 16 minutes and the device is used in addition to brushing.

A light therapy toothbrush (BioLight Illume, Therasage TheraSmile) is a sonic toothbrush with LEDs in the head. It adds light to the brushing you already do, two minutes twice a day, with no extra session. The Illume runs 31,000 to 40,000 vibrations per minute, five modes, a 90-day battery and IPX7 waterproofing.

Buy the mouthpiece for a dedicated oral session; buy the toothbrush if the only routine you will keep is brushing. Many people run both.

• 630 nm red: the core wavelength, used for gum tissue. On all four devices.
• 850 nm near infrared: reaches deeper tissue below the gum line. On the Guardian and Guardian+.
• 460 nm blue: used for surface bacteria and brightness. On the Guardian+ and the Illume toothbrush.

The Guardian+ is the only device with all three; it has three settings, a 5-minute timer and ships with three mouthpiece sizes. Stated irradiance is published for the Guardian (65 mW/cm2).

Research on oral photobiomodulation covers gum health and comfort after dental work in small studies. The devices here are sold as oral care accessories; they are not treatments for gum disease and do not replace cleanings. If you are researching the topic, our blog covers red light therapy for gums.
