Oralumi is built on two well-studied things: red and near-infrared light, which have been researched for years in periodontal care, and blue light, which has been studied for what it does to oral bacteria.
Below are real, published papers on both — with links, so you can read them yourself rather than taking our word for it. At the bottom we’ve set out plainly what this evidence does and doesn’t establish.
Red and near-infrared light
660nm · 830nmIn the literature this is called photobiomodulation, or low-level light therapy. It has been studied mainly as an addition to professional periodontal treatment, looking at inflammation, bleeding and tissue healing at the gumline.
Adjunctive photobiomodulation to basic periodontal therapy
Pooled randomised trials testing whether adding low-power light to standard periodontal treatment improves clinical outcomes over the treatment alone, and compared different ways of applying it.
Read the studyAdjunct 660nm LED irradiation during non-surgical periodontal therapy
A controlled trial using an LED at the same red wavelength Oralumi uses — 660nm — alongside standard periodontal treatment, measuring clinical response at the gumline.
Read the studyLaser phototherapy at 660nm for reducing gingival inflammation
Examined red light at 660nm applied to inflamed gum tissue, reporting that it was beneficial for reducing gingival inflammation in the population studied.
Read the studyPhotobiomodulation as an adjunct in patients with diabetes and chronic periodontitis
Looked specifically at people whose gum disease is harder to treat because of type 2 diabetes, and whether adding light therapy to scaling and root planing changed outcomes.
Read the studyLow-level laser therapy for gingival inflammation in children and adolescents
Brings together in vitro, animal and clinical work on red light and gum inflammation in younger patients — useful as an overview of where the evidence currently stands.
Read the reviewMechanisms and mitochondrial redox signalling in photobiomodulation
The standard reference on why red and near-infrared light affect cells at all: absorption in the mitochondria and the signalling that follows. Written by the field’s most-cited researcher.
Read the reviewBlue light
460nmBlue light in the 400–470nm range has been studied for its direct effect on bacteria — including the species that live along the gumline and contribute to bad breath. Most of this work is laboratory work on biofilms.
Efficacy of an LED toothbrush on a Porphyromonas gingivalis biofilm
The closest study to our product: an LED toothbrush tested against a biofilm of P. gingivalis, one of the main bacteria implicated in gum disease.
Read the studyAntimicrobial effect of blue light using Porphyromonas gingivalis pigment
Shows the mechanism behind blue light’s effect on this particular bacterium: its own pigment absorbs blue light, which is what makes it vulnerable without any added dye.
Read the studyThe effect of blue light on periodontal biofilm growth
Tested how blue light affects the growth of multi-species periodontal biofilm — the mixed community that actually forms along a real gumline, rather than a single isolated species.
Read the studyAntimicrobial blue light: an emerging alternative to antibiotics
A broad overview of why blue light kills bacteria across many species, and why resistance to it has not been observed the way it has with antibiotics.
Read the reviewWhy gums and breath are connected
If you have ever wondered why bleeding gums and bad breath tend to arrive together, this is the link.
Volatile sulfur compounds in patients with gingivitis and periodontitis
Volatile sulfur compounds are what bad breath actually is. This study measured them in people with gum inflammation, connecting the state of the gumline to the smell of the mouth.
Read the studyAntimicrobial light therapy on the tongue dorsum for halitosis
A controlled trial treating the back of the tongue with light and measuring both the reduction in halitosis and how long the effect lasted. Note this trial used light together with a photosensitising agent, not light alone.

The studies linked on this page are the work of their authors and their publishers, and are cited here so you can read them directly. They concern red, near-infrared and blue light in general — they are not studies of the Oralumi brush, and nothing on this page is a claim that our product produces the outcomes reported in them. Oralumi is a toothbrush, not a medical device, and it is not a substitute for care from a dentist. If your gums bleed regularly, have them looked at.
