Pyorrhea is a severe infection of the gums. It is triggered by bacteria that may build on your teeth and gums, which act as plaque. Although you can remove the plaque by brushing your teeth twice a day, you may still have some plaque left after taking meals. Poor oral hygiene is the main cause of pyorrhoea that occurs along with indigestion and hyperacidity.

Calculus, which is the hard form of the plaque, removal of that is hard and beneath it, the bacterial growth may produce toxins that irritate the gums, causing them to be inflamed and bleed eventually.

Other conditions that may contribute to gum and teeth infection or pyorrhea is the presence of chemical irritants in the mouth, a buildup of food particles, poor hygiene practices, and improper use of toothpicks.
