A member asked:

Can the same blue light that treats acne also promote oral health?

This is not the same: You are referring to photodynamic therapy treatment for acne. We do not use this type of light therapy in dentistry. There are special lasers to treat oral conditions, but not the same.

Wavelength Important: Lasers are monochromatic which means they emit a single pure color. Most studies show that lasers in the 720 to 920 nanometer range (red & near infrared colors) can provide biostimulation and low level light therapy. Search lllt on internet for scientific studies. Erbium yag & ysgg lasers in the 2000 to 2300 nm far infrared range have been used to treat periodontal bone loss & reduce pockets.

No: If the blue light is a source of uv radiation it would only burn your gums.
