BON CHARGE™ explores how targeted wavelengths of red and near-infrared light can support skin, muscles, sleep, and energy — and one daily ritual that may be missing out: your mouth. Research suggests specific wavelengths of red and near-infrared light may support the tissues at the foundation of your smile — your gums — and when your gums feel good, your whole smile tends to follow.¹

How Near-Infrared and Red Light May Support Oral Health

Near-infrared and red light are well known for supporting the body in skin treatments, muscle recovery and relaxation routines. These wavelengths are absorbed by cells and may encourage natural cellular energy (ATP) production², supporting the body’s built-in renewal processes.³

When the same light is applied inside the mouth, gum cells — like skin cells — respond by becoming energised, which helps them maintain structure and function.⁴

One Smile. Two Wavelengths. More Support.

The mouth is composed of complex layers that determine how a smile looks, feels, and functions. Red and near-infrared light act at different depths: combined, they can support gums from the surface down, producing benefits that build gently over time. Preliminary studies suggest visible and near-infrared wavelengths can help maintain a balanced oral environment and support the oral microbiome.⁵

Studies indicate these wavelengths can soothe gum irritation⁶, support natural renewal processes^{4, 7–9}, and help calm sensitivity.¹⁰

Red Light: Surface-Level Support

Red light is visible and reaches the upper tissue layers where irritation and sensitivity often begin. Red light may:

• Support healthy gum tissue alongside professional cleaning.¹¹
• Energise cells for daily support and faster recovery.⁹
• Help manage mild gum irritation symptoms.^{4, 7, 8}

Near-Infrared: Deeper Tissue Benefits

Near-infrared light penetrates deeper than red light, allowing it to reach below the gum surface where foundational support is needed. Near-infrared may:

• Stimulate local circulation at a deeper level.^13–15
• Support healthy cellular activity beneath the surface.^{1, 16}
• Encourage long-term tissue vitality.¹⁷

Together, these wavelengths provide complementary support: surface-level calm from red light and deeper activation from near-infrared, forming a gentle, consistent oral wellness approach without adding extra time to your routine.¹⁸

Why the Gums Matter

Even with regular brushing and flossing, gums are often overlooked. They are the foundation of your smile — when under stress you may notice occasional sensitivity, mild discomfort or tension. Light-based care interacts with gum tissue below the surface to offer gentle support where it may help most.¹⁸

A Familiar Technology, Now for Your Smile

Red light therapy is not new: practitioners and physiotherapists have used it for years to calm the body and support recovery.^{19, 20} Now, combining red and near-infrared wavelengths in the context of oral care is showing promising results. It’s simple, non-invasive, and integrates easily into the minutes you already spend brushing: no added steps, just simplified wellness.

Why Smiles Deserve More

Self-care often misses the smile. A healthy smile is more than brightness — it’s about supporting gums, teeth, and small rituals that help you feel your best. Light-based oral care is promising because it’s gentle, science-backed and easy to adopt.

Supporting Long-Term Oral Health

Light-based oral care can fit into your daily brushing routine to support smile longevity between dental visits. If you are undergoing dental treatment or have pre-existing health conditions, check with a qualified healthcare professional before starting.

What’s Next

BON CHARGE™ has explored how light supports sleep, skin and wellbeing — and now the smile. If red light is already part of your ritual, you’ll soon be able to take it one step further. Something is coming that brings red and near-infrared light to an overlooked part of your wellness routine: designed to support gums, glow and your whole smile. Stay tuned.
