6 Foods That Ruin Your Smile

I have yellow teeth and is wondering where am I getting the stain or the sources. Which foods or even drinks? So, to answer my own questions, I searched the net and found this very informative site. And here they are. If you guys have the same problem with your teeth discoloration.

Dr. Catrise Austin, cosmetic dentist to the stars and founder of VIP Smiles, weighs in on which foods and drinks could be destroying your smile.

1. Coffee and Tea. Caffeine addicts might cringe, but the dark pigmentation in these popular morning beverages can stain your teeth. "The rule of thumb is that anything that can stain a white t-shirt can harm the color of your smile," says Austin. If you consume these beverages daily, you may lose your white smile. Fortunately, these types of stains can be removed easily with a professional cleaning from your dentist. You should also be aware of how much sugar you're adding to your coffee or tea—too much can contribute to cavities.
2. Red Wine. It may be good for the heart, but red wine is bad for maintaining a bright smile. The red color can discolor your teeth over time, giving your smile a dull appearance. The same goes for dark berries, such as blueberries, raspberries, and strawberries.
3. Dark Colas. Dark colas are just as bad for the color of your teeth as coffee and teas. Most sodas are acidic and have a high sugar content, both of which can rot your teeth over time. If you don't brush or rinse your mouth after drinking colas, the acid and sugar will continue to stick to your teeth long after you finish the drink, and they'll continue to do their dirty work.

Lots of sugar and acid in the following three foods could give you fewer reasons to smile.

4. Chocolate. Like coffee, the dark and rich texture of certain types of chocolate can wear away and discolor the tooth enamel. The high sugar content also leads to cavities and decay if teeth are not properly brushed.
5. Candy. It's well known that the sugar content of candy can erode the teeth's enamel and lead to cavities, but biting down on hard candies can also cause fracture lines or chips in your teeth, ruining the overall appearance of your smile.
6. Citrus Fruits. Fruits such as lemons and limes are highly acidic. If acid frequently comes into direct contact with the teeth's enamel, over time, it can erode your teeth by causing craters, notches, or holes.
