Juice isn't the Foolproof soda Alternative

Sports drinks, energy drinks and juices seem to provide at least some nutritional benefits and are often the alternative to sugary sodas; however these drinks are loaded with sugar, too, which eventually causes tooth decay.
Children are especially susceptible to tooth decay caused by sugary drinks, depending on their sippy cup usage. The spout of the cup places drinks in close contact with tooth enamel, and children often "nurse" a cup in such a way that their teeth are constantly bathed with the sugary drink. Even 100% pure juice is advisable only in limited quantities because of its naturally high sugar content.
Some parents often give their children fruit juice, milk or fruit snacks before bed. The sugars coat the teeth overnight and can cause a condition called baby bottle tooth decay, which is early childhood tooth rot. Prevent this overnight decay by always brushing your teeth and your kids teeth before bed.
