A study published this year in the Journal of Dentistry showed that orange juice decreased enamel hardness by 84 percent. Lemon, orange and grapefruit juice can strip away the enamel with their acidity.
TIP 1. When you drink orange juice, have it in one sitting versus sipping it over a longer period.
TIP 2. Use a straw to limit juice exposure on your teeth.
TIP 3. Match citric foods with less acidic ones, like grapefruit slices in a salad.
