Although fluoride, a key ingredient in toothpaste, is essential for oral health, excessive use in children under six can have adverse effects.

At this age, children’s teeth are still developing. If fluoride intake is not controlled, it can damage tooth enamel, cause tooth pain, and lead to brown stains on the teeth.

To limit fluoride exposure, parents should supervise the amount of toothpaste their children use, ensuring they only apply a pea-sized amount each time they brush. Children should also be reminded not to swallow toothpaste.

For children under three, it is best to avoid using toothpaste altogether. Instead, parents should clean their teeth with a soft toothbrush.

By the age of six, the negative effects of fluoride on teeth are less significant, and children become more skilled at brushing. As a result, parents no longer need to strictly monitor their toothpaste usage.
