The Centers for Disease Control reports that most tooth decay in children and teens occurs:





Correct Answer:
on chewing surfaces.


the correct answer to the question regarding where most tooth decay in children and teens occurs, as reported by the centers for disease control (cdc), is on the chewing surfaces of teeth. this specific area is more prone to decay due to its unique structure and function.

chewing surfaces refer to the top surfaces of the molars and premolars, which are used primarily for grinding food. these surfaces are characterized by grooves and indentations, known as pits and fissures. these structural features, while effective for their function in mastication, also create small spaces that are difficult to clean. as a result, they tend to trap food particles and bacteria more than other parts of the tooth.

the accumulation of food particles and bacteria in these pits and fissures forms plaque—a sticky, colorless film of bacteria. if plaque is not removed effectively through regular brushing and flossing, it can lead to the formation of acids produced by bacteria as they metabolize the trapped food particles. these acids start to erode the enamel, which is the hard, outer layer of the tooth, eventually leading to cavities (dental caries).

prevention of decay in these areas includes proper oral hygiene practices such as regular brushing with fluoride toothpaste, flossing, and using dental sealants. dental sealants are a protective coating applied by dental professionals to the chewing surfaces of the back teeth to cover the pits and fissures. this sealant acts as a barrier, protecting the enamel from plaque and acids.

understanding the susceptibility of the chewing surfaces to decay can help in focusing preventive care to maintain dental health in children and teens, thereby reducing the incidence of cavities and associated dental problems.
