What factor significantly influences the development of dental caries?

Poor oral hygiene is a significant factor influencing the development of dental caries because it directly affects the accumulation of plaque, a sticky film of bacteria that forms on teeth. When oral hygiene practices are not maintained, food particles and bacterial plaque remain on the teeth, allowing the bacteria to metabolize sugars from the diet into acids. These acids erode tooth enamel, leading to demineralization and, eventually, caries formation.

Regular and effective oral hygiene practices, including brushing and flossing, help to remove plaque and food debris, thus reducing the risk of cavity formation. When individuals do not regularly clean their teeth, they create an environment where bacteria can thrive, significantly increasing the likelihood of developing dental caries.

While other factors, like genetics, frequent snacking, and fluoride overuse, can play roles in caries development, they do not have as direct an impact on the immediate environment in the mouth as poor oral hygiene does. Genetics may predispose individuals to certain dental issues, and frequent snacking can provide a continual supply of sugars for bacteria to exploit, but without proper oral hygiene, the consequences become much more severe in terms of cavity development. Fluoride, while essential for dental health, only serves as a preventive agent against caries when
