Gum disease (periodontal disease):
Gum disease means infection or inflammation of the tissues that surround the teeth. Most cases of gum disease are plaque-related. Plaque contains many different types of bacteria and a build-up of some types of bacteria is associated with developing gum disease.
Prevention of Gum disease (periodontal disease):
Gum disease is caused by harmful bacteria that are found just below the gum line. To ensure the prevention of gum disease, these bacteria must be disturbed on a regular basis with your toothbrush and interdental floss or brushe.
It is important that your toothbrushing regime also includes brushing towards your gums and not just your teeth otherwise you may still be at risk of gum disease.
