Wine
Red wine is an acidic beverage, which means it can cause a lot of harm to your teeth. It has both chromogens and tannins, both of which are known to stain your teeth. But red wine is not the only culprit, white wine has also been shown to play a role in the staining of your teeth.
Tea
Many dentists will tell you that tea stains your teeth worse than coffee. Black teas contain many tannins, just like the ones found in red wine. Other teas do not do as much damage.
Soda
Sodas are very acidic, which means they make it easier for other foods and beverages to stain your teeth. Some specific sodas, like cola, are also full of chromogens, which can cause staining.
Sports Drinks
Sports drinks can also be very acidic. Drinks that have high acidity levels can cause the enamel in your teeth to soften, which makes it easier for staining to occur.
Berries
Some berries, such as blueberries, blackberries, cherries, or pomegranates, can stain your teeth because of their coloring. These fruits do not have to be in their natural form. Foods or drinks with these berries can also stain your teeth.
Sauces
Dark colored sauces, such as tomato sauce and soy sauce, known to be stain promoting as well. Be sure to brush your teeth right after eating foods covered in a dark sauce.
Sweets
Many candies and other sweet snacks have coloring added to them that can stain your teeth. If your tongue turns a different color, there's a good chance that whatever you just ate will have an effect on your teeth as well.
Pickles and Ketchup
Both of these foods are extremely acidic. They will make your tooth enamel more delicate, making it easier for staining to occur.
Balsalmic Vinegar
This popular salad dressing is also very acidic. But, if you eat it over lettuce, the lettuce can form a protective barrier over your teeth to prevent some of the staining.
Beets
Beets can do a lot of harm to your clothing, so why wouldn't they do the same to your teeth. The coloring and ingredients in beets make them another teeth staining food.
Curry
This Indian food flavoring has a lot of yellow coloring in it. As a result, it can easily stain your pearly whites with an unattractive yellowing color.
Juice
Particular juices, such as grape, pomegranate, and cranberry, have a lot of pigmentation. Because of this, they are known to cause staining.
