What’s Hiding in Your Toothpaste? Fluoride: Friend or Foe?

Fluoride protects teeth and fights cavities — that’s why it’s been in toothpaste since 1914. But how much is too much, especially for kids?Fluoride is a natural mineral found in water, soil, and even the food we eat. In small amounts, it strengthens enamel. But too much can lead to fluorosis, digestive issues, and even affect bone development. That’s why pediatricians recommend using only a pea-sized amount of fluoride toothpaste for toddlers.
