Dental caries, also known as tooth decay or cavity, is a disease where bacterial processes damage hard tooth structure (enamel, dentin, and cementum).[1] These tissues progressively break down, producing dental caries (cavities, holes in the teeth). Two groups of bacteria are responsible for initiating caries: Streptococcus mutansLactobacillus. If left untreated, the disease can lead to pain, tooth loss, infection, and, in severe cases, death.[2] Today, caries remains one of the most common diseases throughout the world. Cariology is the study of dental caries.
