What is a hardened plaque that hurts gum health?

A hardened plaque that negatively affects gum health is known as tartar or calculus. It forms when plaque, a sticky film of bacteria, is not removed through regular brushing and flossing, leading to mineralization. Tartar can irritate the gums, causing inflammation and potentially leading to gum disease, which can result in pain, swelling, and even tooth loss if left untreated. Regular dental cleanings help remove tartar and maintain healthy gums.
