Cavities, Gingivitis and Periodontal Disease: Meet Blue Light
While its we’ve seen hydrogen peroxide (H2O2) in our oral hygiene products before, such as baking soda and hydrogen peroxide toothpaste, new research adds a new twist to the proven oral debrider. Often, the bacteria that need to be reached live in structures called biofilms, which serve as a physical barrier to reach them. Apparently the combination of both blue light (typically used in dental offices to set fillings) and hydrogen peroxide can penetrate deep into the biofilms and kill bacteria that have been unreachable by traditional non-invasive means.
