We all know that toothpastes contain fluoride. It is because it helps prevent cavities. Similarly many foods have fluorides for the same reason. But, it is good only to a particular amount. And too much of fluoride can lead to fluorosis — leading to white streaks on your teeth. The most severe form shows up as severe discoloration and erosion of the teeth too! It also makes it more porous and susceptible to decay.
Juice is good for your child’s health, true. But, children who consume 100-percent juice had slightly more risk of developing fluorosis than the ones who did not consume to this amount. Thus, consuming fluoridated beverages seemed to affect teeth that had not come in yet.
