What causes root caries?

Actinomyces
Streptococcus
Candida
Lactobacillus

The correct answer is: Actinomyces

Root caries is an infectious disease caused by bacteria in the mouth. When there is a loss of mineral content in tooth enamel due to acids produced by bacteria, it can lead to tooth decay or root caries. Out of all the options given, Actinomyces is the most common bacteria responsible for root caries. Streptococcus, Candida, and Lactobacillus are also types of bacteria found in the mouth, but are not known for causing root caries. Therefore, A is the correct answer.
