Fluoride and Children
Younger kids who often swallow toothpaste are at risk of developing dental fluorosis or the appearance of white streaks or spots on the enamel of their adult teeth. This condition can happen when a large amounts of fluoride are ingested while teeth are developing–usually between the ages of 3 months to eight years.
The ADA advises parents to keep a close eye on their young children during tooth-brushing time, and suggests that they always use toothpaste with an appropriate fluoride content for a child.
