Could the same blue light that treats acne also promote oral health?
I know that the blue 405-420 nanometer wavelength blue light has provided significant sub-dermal bacteria reduction. Could it do the same for sub-gingival bacteria?
The answer is "no" for several reasons. First, oral bacteria is completely different from dermal bacteria. None of the strains of oral microbes have been shown to have their growth be altered by exposure to any type of light, including the blue light range.
Secondly, subgingival bacteria is just that: deeply embedded beneath the overlying tissues. As such, light is not able to penetrate sufficiently to effect any changes.
I hope this helps.
