According to Dr. Julian Feneley, phototherapy from a blue light kills the pathogens which cause gum and periodontal disease as well as bacteria which can lead to heart attacks and strokes.
He says one hour of the blue light can result in anti- bacterial benefits that last up to two years.
Dr. Feneley who runs the BriteSmile chain of teeth whitening centers says the blue light treatments usually run around $500 per session.
Although the blue light treatment can kill off the bacteria that causes halitosis and bacteria linked to heart attacks and strokes, he says there are no plans to research how much the treatment might reduce those problems for at-risk patients.
An enlightening study about the blue light tooth treatments appears in the current issue of Journal Of Antimicrobial Agents And Chemotherapy.
