Yes, flossing is an essential part of proper daily oral hygiene. Although studies have not necessarily shown flossing to decrease cavities, it has been shown to help prevent periodontal disease!
Gingivitis is the initial presentation of periodontal infection, and signs of gingivitis include bleeding gums, inflamed gums, and red gums. Gingivitis is easily reversible by proper brushing techniques and flossing daily. After a week of good home care, all signs of gingivitis will disappear.
Periodontal disease, on the other hand, is a more severe infection of the gums and can lead to bone loss around teeth. This bone loss can result in the loss of teeth! Although periodontal disease can be diagnosed ewrly and halted, its destruction cannot be reversed. The best way to prevent periodontal disease is by visiting your dentist regularly, brushing twice a day, and flossing daily.
So YES, you should floss….but only if you want to keep your teeth!
