What You Eat and Drink Can Stain Your Teeth
Foods and Drinks: Some foods and drinks are known to stain teeth and even worse break down your tooth enamel. Foods and drinks like cranberry juice, grape juice and blueberries can all discolor teeth if you repeatedly consume them.
Also, acidic foods like tomatoes and oranges can cause yellow teeth. Try to get into the habit of rinsing their mouth out after eating and drinking to minimize the effects of foods or drinks.
