If you ask yourself whether it’s normal or not to have bleeding gums while brushing your teeth, well it surely isn’t. If your gums bleed it is then very likely that you have gum disease (or periodontal disease), which is the inflammation of the gums and it includes gingivitis and periodontitis.
Gingivitis is a mild form of gum disease and it can be expressed by pain, bleeding and redness of the gums. It is often caused by poor oral hygiene, but it’s reversible with professional cleaning and good oral home care.
Periodontitis is a more advanced stage of the disease and it occurs when gingivitis isn’t untreated. Plaque and toxins from bacteria go destroy the bone that supports teeth forming spaces between the gums and the teeth, making them eventually loose.
Periodontitis can also be a manifestation of systemic diseases such as heart disease, respiratory disease, and diabetes. But pre-existing periodontal disease can also worsen those conditions and cause serious medical illnesses.
