Gum disease is not just “bad breath” or a dental issue. It’s a chronic inflammatory problem driven by bacteria, plaque biofilm, and constant reseeding from the tongue, pockets, and gumline. In this video I break down what gum disease actually is, why it’s so common, and why it can flare even when you think you’re doing everything right.

Then we get into the interesting part: red light and near-infrared light (photobiomodulation). This is not a “burn the bacteria with a laser” idea. It’s a low-energy signaling effect that can help calm inflammation and support tissue healing. The research trend (not perfection, not magic) is that when photobiomodulation is used as an add-on to standard dental care like scaling and root planing, many studies show improvements in bleeding and inflammation, and in some cases better pocket-depth outcomes.

Think of it as an adjunct that helps gums heal better and stay calmer between visits, especially if you’re prone to bleeding and inflammation.

Studies:
Photobiomodulation/LED during non-surgical periodontal therapy (clinical trial)
Chen YW, et al. Randomized controlled clinical effectiveness of adjunct 660-nm light-emitting diode irradiation during non-surgical periodontal therapy. J Formos Med Assoc. 2020. PMID: 30709694
Takeaway: LED (660 nm) used during/after scaling and root planing helped periodontal recovery, especially in severe sites.

Laser + LED adjunct to scaling and root planing (1-year split-mouth RCT)
Giannelli M, et al. Treatment of severe periodontitis with a laser and light-emitting diode (LED) procedure adjunctive to scaling and root planing: double-blind randomized split-mouth trial with 1-year outcomes. Lasers Med Sci. 2018. PMID: 29349511

Systematic review: PBM as adjunct to non-surgical periodontal therapy
Dalvi S, et al. Effectiveness of photobiomodulation therapy as an adjunct to non-surgical periodontal therapy in periodontitis: systematic review of in vivo human studies. DOI: 10.1111/php.13348 (2021).

Lab study: gingival fibroblasts (collagen + growth factor signals)
Karoussis IK, et al. Dosage effects of an 810 nm diode laser on human gingival fibroblasts (proliferation, collagen production, growth factor expression). 2021. PMID: 34733748
Takeaway: 810 nm PBM showed beneficial effects on gingival fibroblast proliferation/collagen-related markers in vitro (dose-dependent).
