What bacteria is noted for its later involvement in the development of dental caries?

The development of dental caries, commonly known as tooth decay, is primarily initiated by specific types of bacteria that contribute to the demineralization of tooth enamel. The correct choice, which is Streptococcus mutans, is recognized as the primary bacterium involved in the early stages of caries formation. This bacterium is highly adept at metabolizing sugars to produce acid, which lowers the pH in the oral environment and leads to enamel demineralization.

While Lactobacillus is indeed involved in the later stages of caries progression, contributing to the continued breakdown of dentin and secondary lesions, it is not the initial bacterium responsible for initiating the carious process. Therefore, while Lactobacillus plays a significant role in the progression of dental caries, it is not the bacterium that is primarily noted for the formation of caries from the beginning.

Bacteria such as Staphylococcus aureus and Bacillus anthracis are not typically associated with dental caries. Staphylococcus aureus is more commonly linked to other infections and conditions, and Bacillus anthracis is known for causing anthrax, which is entirely unrelated to oral health and dental caries.
