Dear student
Dental caries, also known as tooth decay or a cavity, is a disease where bacterial processes change carbohydrate like sugar in food left on teeth to acid that demineralizes hard tooth structure ( enamel, dentin, and cementum ). If demineralization exceeds saliva and other remineralization like from calcium, these tissues progressively break down, producing dental caries (cavities, holes in the teeth). Two groups of bacteria are responsible for initiating caries: Streptococcus mutans and Lactobacillus.
