What is GLO light-assisted peroxide whitening?
GLO whitening is a light-assisted peroxide whitening system that aims to reduce tooth stain after a dental check and protection of the gums.
How do peroxide gel, light and warmth affect tooth colour?
The whitening gel contains peroxide, which oxidizes colour compounds in enamel and dentine; the device supplies light and warmth according to the manufacturer’s protocol.
What affects the results of GLO teeth whitening treatment?
Results depend on the starting shade, cause of discolouration, enamel condition, exposure to staining foods, and whether fillings or crowns are present.
