Dental caries is a disease that occurs due to damage to tooth enamel. Enamel is the outer layer of the tooth that protects the tooth from external influences and prevents the destruction of dentin (the inner layer of the tooth). If the outer layers of the tooth are damaged under the influence of bacteria or acids, the bacteria begin to penetrate into the deeper layers of the tooth - dentin, where the nerve is located and inflammation of the tooth tissue (pulpitis) or even tooth destruction (edentia) can occur.
