Bacteria (Streptococcus mutans)

Streptococcus mutans is a type of bacteria commonly found in the human mouth. It plays a significant role in the development of dental cavities by converting sugars from food and drinks into acids. These acids weaken tooth enamel over time, leading to decay and cavities. S. mutans can adhere to the tooth surface and form plaque—a sticky, colorless film—creating a breeding ground for bacteria. Good oral hygiene, like brushing and flossing regularly, along with reducing sugar intake, helps control S. mutans levels and prevent tooth decay.
