Red & Blue Gum Therapy Light — Support Healthy Gums Naturally — 16 Red 16 Blue LEDs
Starlite Smile's Red & Blue LED Gum Therapy Light is a 32-LED wireless rechargeable mouth tray that combines two clinically studied wavelengths — 635nm red and 455nm blue — in a single at-home oral care device. Each wavelength has been independently studied in dental and photobiomodulation research for its potential effects on gum tissue, circulation, and oral bacteria. This is a beauty and wellness device, not a medical treatment, but it is built around the same wavelengths explored in that research.
For best results, use every day for at least two months before evaluating your experience.
How Each Wavelength Works
635nm Red Light — The Gum-Comfort Wavelength
Red light at 635nm falls within the visible spectrum and is among the most researched wavelengths in dental photobiomodulation. Studies have explored its potential to support gum tissue comfort, reduce sensitivity, and promote circulation at the gumline. The 630–660nm range is commonly used in low-level laser therapy (LLLT) research focused on periodontal soft tissue. This device uses 635nm — a precise, targeted frequency within that studied range.
455nm Blue Light — The Bacteria & Whitening Wavelength
Blue light at 455nm has been studied for its ability to selectively target certain bacteria found in the oral environment. According to Harvard Magazine, blue LED light therapy represents a discovery with "important implications for preventing and treating periodontal disease." Researchers at the Forsythe Institute have studied blue light's ability to suppress bacteria commonly associated with poor gum health. Separately, 455nm blue light is widely used in professional and at-home teeth whitening protocols as a gel or strip activator.

How to Use
- Gently wash the tray with a few drops of soap and water, then rinse and dry thoroughly — do not allow the base to get wet
- Insert the tray into your mouth — the lights will flood the whole mouth including teeth and gums not directly in the tray
- For Blue solo mode (fresh breath / whitening): Click the button 1 time. Run for 15 minutes. For whitening: Gel and strips sold separately — always follow the instructions on your whitening product. Starlite Smile is not responsible for any issues resulting from adding gel, strips, or other third-party products to this device.
- For Red + Blue mode (gum support): Click the button 2 times. Run for 10 minutes. If you experience no sensitivity, you can run back-to-back sessions.
- Remove tray, spit into sink, and rinse mouth
- Wash and thoroughly dry the tray and store safely between uses
Charging: Light flashing blue? The light flashes blue when it needs charging and also flashes while charging — it will not operate while flashing blue. Charge for approximately 2–3 hours every 3–4 days. If for any reason the light won't stop flashing, contact us for a replacement.
This device does not replace brushing, flossing, or professional dental care. For best results, use daily for at least two months before evaluating your experience.
Frequently Asked Questions
What is the difference between the Red + Blue mode and Blue solo mode?
Blue solo mode (1 click) activates only the 455nm blue LEDs — this is used for fresh-breath routines or to support whitening gel or strips, recommended for 15 minutes per session or as directed by your whitening product. Red + Blue mode (2 clicks) activates both 635nm red and 455nm blue LEDs simultaneously — this is the gum-support setting, recommended for 10 minutes per session.
What does 635nm red light do for gums?
Red light at 635nm has been studied in photobiomodulation and dental research for its potential effects on gum tissue comfort, sensitivity, and circulation at the gumline. The 630–660nm range is among the most researched wavelength bands in low-level laser therapy (LLLT) focused on periodontal tissue. This device is not a medical treatment, but it uses the same 635nm wavelength explored in that research.
What does 455nm blue light do in an oral care device?
Blue light at 455nm has been studied for its ability to selectively suppress certain bacteria found in the oral environment. Harvard Magazine has cited research suggesting blue LED light therapy has "important implications for preventing and treating periodontal disease." The Forsythe Institute has studied blue light's ability to target bacteria associated with poor gum health. Blue light at this wavelength is also used as whitening gel support in professional and at-home whitening protocols.
Is this a medical device?
No. This is a beauty and wellness device. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or condition. It uses the same wavelengths explored in dental and photobiomodulation research, but those findings do not apply to this specific product. Always consult your dentist before adding any new tool to your oral care routine.
How do I charge the device?
Connect the included USB charger to the device and plug the other end into a USB power source. The light flashes blue when it needs charging and continues flashing while charging — this is normal. The device cannot be used while charging. Charge for approximately 2–3 hours every 3–4 days depending on usage.
Can I use this device with whitening gel or strips?
Yes — select Blue solo mode (1 click) and run for 15 minutes or follow the timing on your whitening gel or strip packaging. Gel and strips are not included and must be purchased separately. Always follow your whitening product's instructions and discontinue use if sensitivity occurs. Starlite Smile is not responsible for any issues resulting from adding third-party products to this device.
How often should I use this device?
For gum support, use Red + Blue mode 1–3 times daily for 10 minutes per session. For whitening support or fresh breath, use Blue solo mode once daily for 15 minutes or as directed by your whitening product. Always check with your dentist for best practice. For best results, use every day for at least two months before evaluating your experience.
How do I clean the device?
Gently wash the silicone tray with a few drops of mild soap and warm water, then rinse and dry thoroughly. Do not allow the base of the tray or the cord/connectors to get wet.
What is the return and guarantee policy?
This device is backed by a 90-day replacement guarantee for defective or malfunctioning units when purchased from Starlite Smile. Because it is an oral hygiene device, it cannot be returned — but defective units will be promptly replaced. Click Contact Us for ways to get in touch.
My light keeps flashing blue — what do I do?
First, make sure the device is connected to the charger and a USB power source. Leave it on the charger overnight. If it still won't stop blinking after a full overnight charge, contact Starlite Smile — we offer a no-hassle replacement for units that won't hold a charge or won't stop flashing.
