Cariogenic means producing or promoting what?

Cariogenic means producing or promoting what?

• A. Tooth decay
• B. Dental plaque
• C. Healthy enamel
• D. Oral bacteria

Answer: (A)

Cariogenic describes something that promotes tooth decay. When foods rich in sugar are eaten, bacteria in the dental plaque metabolize those sugars and produce acids. Those acids lower the mouth’s pH and begin to demineralize the enamel, eventually leading to cavities. So the feature described as cariogenic is what ultimately happens—the tooth decay itself. The environment—dental plaque—provides the bacteria that carry out this process, and healthy enamel resists decay, so they aren’t what cariogenic refers to. Some oral bacteria can contribute to decay, but the term specifically points to the promotion of decay, i.e., tooth decay.
