Orange Juice—Good for You, But What About Your Teeth?

orange juice and your teethBreakfast isn’t the same without something refreshing to wash it down. Most breakfast tables are not complete without cups of milk, coffee, and usually orange juice. Milk and orange juice are well-known for providing our bodies with significant amounts of minerals and nutrients. They are recommended for reducing the risk of future health issues, including heart disease. Milk is also famous for providing calcium and phosphate that help remineralization of tooth enamel. Yet, with the high acidic content of orange juice, can it be harming your teeth as well as helping your body?

What You’ll Find in Each Glass

While rich in vitamin C, orange and other fruit juices contain high quantities of sugars and harmful elements, such as citric acid. In fact, most fruit juices have a pH (acidity level) of less than four (the lower a substance’s pH is, the more acidic it is). When orange juice interacts with plaque in your mouth, it also lowers the pH level of that plaque. Once plaque’s pH reaches 5.5 or lower, it becomes acidic and attacks your teeth, softening the enamel and reducing its ability to protect your teeth from infection, damage, decay, and stains.

Drink With Caution

There is no doubt that orange juice is an excellent source for many essential minerals and nutrients. You don’t have to quit drinking orange juice in order to protect your teeth. Instead, we advise drinking orange juice through a straw to reduce the risk of sugar and acid damage. Be sure to position the straw towards the back of the mouth, and avoid chewing it. Shoving the straw in between your teeth can harm your gums or create spaces between your teeth.
