To keep your teeth healthy and free of cavities you should avoid drinking flavored fruit juices. Fruit juices contain tons of cavity-causing sugars. In fact, although fruit juices sound as if they are good for you, in reality, they have just as much sugar as soda pop. Drink water instead.
When you don't have time to brush, consider chewing a piece of sugar-free gum instead. Avoid aspartame as studies have shown it can have some frightening side effects health-wise. Instead, find gums, which include Xylitol such as Pur gum to have a healthy way to clean your teeth after meals.
