Which of the following is considered an effective preventive measure against cavities?

Using fluoride toothpaste is widely recognized as an effective preventive measure against cavities. Fluoride helps to strengthen tooth enamel, making it more resistant to acid attacks from bacteria and sugars in the mouth. When individuals brush their teeth with fluoride toothpaste, they not only remove food particles and plaque but also allow the fluoride to penetrate the enamel, enhancing its mineral content and overall protective ability.

In addition to fluoride’s protective effects, consistent brushing with fluoride toothpaste can significantly decrease the risk of cavity formation by promoting oral hygiene practices that remove decay-causing bacteria and debris. This preventive measure is endorsed by dental professionals and public health organizations, given its proven efficacy in reducing dental caries in both children and adults.

The other options do not support effective cavity prevention. Skipping brushing in the morning would leave plaque and food particles on the teeth, increasing the risk of cavities. Consuming sugary snacks frequently contributes to the demineralization of tooth enamel and promotes the growth of harmful bacteria that lead to cavities. Relying solely on mouthwash without brushing does not effectively remove plaque or food particles, which are essential for maintaining oral health and preventing cavities.
