subject: Blue Light May Keep Gums Healthy [print this page] The researchers found that 500 to 600 of the roughly 700 or so bacteria in the mouth were rapidly killed
by the light.
Gum disease is an infection caused by plaque, a bacterial film that
continuously forms around the teeth. Untreated, gum disease can cause sore,
puffy and bleeding gums, bad breath, loose teeth, and ultimately tooth
loss. Recently, a study published in the April Journal of Antimicrobial Agents
and Chemotherapy and in the February issue of AGD Impact, suggests that
blue light might be useful in preventing, controlling, or treating gum disease.
"Some of the key bacterial pathogens associated with periodontitis (gum
disease) produce and accumulate compounds that are sensitive to light," said
Nikos Soukos, director of the Forsyth Laboratory of Applied Molecular
Photomedicine and the principal investigator. Soukos also found that when
the proportion of such bacteria was reduced, the amount of other, potentially
helpful, bacteria increased. "This suggests that it might one day be feasible to use light to restore a healthy bacterial balance in the mouth," Soukos said. The current research stemmed from an observation by Max Goodson, director of clinical research at Forsyth, that the blue halogen lamp used in a tooth-whitening procedure also appeared to decrease inflammation of the gums. This light source was then applied to dental plaque samples obtained from individuals with existing gum disease. The researchers found that 500 to 600 of the roughly 700 or so bacteria in the mouth were rapidly killed by the light.
Gum disease can be greatly reduced and possibly prevented by effective brushing at least three times a day, and flossing at least once a day. Regardless of what you see on TV, no toothpastes or mouthwash can help cure any form of gum disease except gingivitis, a mild inflammation of the gums. You should see your dentist and dental hygienist at least twice a year for an examination and a professional cleaning. Those diagnosed with gum disease may need their teeth and gums cleaned up to four times a year. You should follow through with your dentist's treatment recommendations, which may include deep cleaning under the gums, antibiotics, or gum surgery. If you smoke, you should consider quitting,
because smoking can make gum disease worse. Although more independent research is needed, a handheld, light-based device now being developed may one day also help fight gum disease.
