Note: There is a difference between periodontitis and gingivitis. Usually they occur in the following progression: a minor gum inflammation turns into gingivitis (serious inflammation of the gums), which, if left untreated, evolves into periodontitis.
Note: While gingivitis can be cured, periodontitis is a condition (like diabetes or high blood pressure) and it cannot be cured. Periodontitis can only be treated and managed.
