plaque

Plaque is a sticky, colorless film composed of bacteria, food particles, and saliva that forms on teeth. If not regularly removed through brushing and flossing, it can harden into tartar and lead to tooth decay and gum disease. In arteries, plaque refers to the buildup of fats, cholesterol, and other substances on arterial walls, which can narrow or block blood flow. This arterial plaque increases the risk of heart attacks and strokes. Proper oral hygiene and a healthy diet are essential to prevent plaque formation both in the mouth and in the arteries.
