If your gums are bleeding it could be a sign that you might develop, or already have, gum disease.
Redness, bleeding, and sore, swollen or painful gums are all symptoms of gingivitis, a form of gum disease that causes the inflammation of the surrounding gum tissue. Its most common cause is the build up of plaque.
It is important to take immediate action as, without proper removal, the plaque hardens and becomes tartar, which in turn worsens gingivitis and can lead to receding gums or even damage the jaw bones.
If untreated, it can also lead to tooth loss and periodontitis. The most severe form of gum infection is the acute necrotizing ulcerative gingivitis (trench mouth).
You can reverse gingivitis by thoroughly removing plaque daily and with regular professional cleaning.
