Cariogenic Bacteria

Cariogenic bacteria are a diverse group of microorganisms that contribute to the development of dental caries by fermenting dietary carbohydrates and producing acids that demineralize tooth enamel. Key species include *Streptococcus mutans*, *Streptococcus sobrinus*, and *Lactobacillus* species. These bacteria possess virulence factors such as acidogenicity, aciduricity, and the ability to form biofilms. While *S. mutans* has been historically emphasized, dental caries is now understood to result from a complex interplay of multiple acid-producing and acid-tolerant organisms. Prevention strategies focus on controlling these microbial populations through methods like improved oral hygiene, dietary modifications, fluoride application, and antimicrobial agents.
