The mouth is like a holographic map for our body — every tooth is neurologically and energetically connected to an organ. If the mouth is inflamed, the body will feel it.
One tool I absolutely love? Targeted photobiomodulation.
Let’s break down how this actually works 👇
Blue light (~415 nm) helps to whiten teeth and balance the oral microbiome while red light (~670 nm) soothes inflammation and stimulates tissue regeneration in teeth and gums.
1️⃣ BLUE LIGHT
Blue light photo-bleaches stains yielding brighter teeth. Studies show blue LED light significantly increases both the rate and final extent of tooth whitening.
Many oral pathogens (e.g. Porphyromonas gingivalis, Streptococcus mutans, Fusobacterium spp.) contain endogenous porphyrins. Blue light excites these porphyrins and generates reactive oxygen species (ROS) that selectively kill bacteria. The net effect is a healthier, more balanced oral microbiome.
2️⃣ RED LIGHT
Red light around 670 nm is absorbed by cytochrome c oxidase (among others) which is a cellular photoreceptor leading to a metabolic cascade resulting in increased ATP production, nitric oxide release (eNOS-derived), and secondary signaling that drive cell growth. In human gingival fibroblasts, 670 nm has been shown to markedly boost proliferation, migration, and collagen (COL1A1) expression. In other words, red photobiomodulation jump-starts the cells that rebuild gum tissue and extracellular matrix. Over repeated use, this speeds healing of micro-injuries and strengthens gums. In clinical context, even NASA scientists reported that red LED light “promote[s] wound healing” in tissue.
