Dental fluorosis is a condition that affects the appearance of teeth and occurs when there is an excess intake of fluoride during the early years of life, specifically while the teeth are still developing. This condition can lead to changes in the enamel, resulting in white spots or streaks on the teeth, and, in more severe cases, can affect the surface texture and color of the enamel.

Fluoride is beneficial for dental health when used in appropriate amounts, as it helps to strengthen enamel and prevent cavities. However, when individuals are exposed to high levels of fluoride—often from sources such as fluoride supplements, high-fluoride dental products, or excessive consumption of fluoridated water—fluorosis can develop. This exposure usually occurs during the years when the permanent teeth are still forming, which is why it's particularly critical for young children to be monitored for fluoride intake.

The other options do not accurately explain the cause of dental fluorosis. Insufficient fluoride exposure, for instance, does not lead to the condition but can instead result in increased susceptibility to cavities. Using abrasive products too frequently primarily affects enamel wear but is not related to fluoride levels. Genetic predisposition may influence a person's overall dental health but does not specifically cause dental fluorosis. Thus,
