This type of laser therapy uses a photosensitizer (dye), which is applied into deep pre-cleaned pockets. This agent is absorbed and later illuminated with a laser unit. Initiated photodynamic reaction destroys not only bacteria but also infected gum cells

Laser-assisted photo disinfection of inflamed gums can significantly improve treatment outcomes when combined with scaling and root planing. It eliminates bacteria and their toxins that are associated with periodontal disease.
