Oral care is mainly concerned with the teeth and the care of them, which includes cleaning and removal of dental plaque using toothpastes, gels and mouthwashes.
The main factors affecting oral health are plaque, calculus, tooth decay, gum disease and bad breath. Plaque is a combination of bacteria, saliva, acid and food particles.
After eating or drinking foods with sugar, a protein in saliva turns sugar into acid and plaque starts forming on the teeth. If plaque is not removed it hardens into calculus, also called tartar.
