Sugary Drinks & Sweets
Candy, soda, and fruit juices all contain a great deal of sugar, making them harmful to your teeth.  Bacteria actually feed on sugar and produce acids that can eat away at your tooth enamel.  Chewy candies, like caramels and jelly beans, get stuck in your teeth, giving the sugar plenty of time to make its mark.  If you are going to eat sweets, choose ones that won’t cling to your teeth, such as chocolate.

Starches
Like sweets, carbohydrates such as breads and pastas tend to get caught in you teeth, as well.  Bacteria feed on carbs, making your risk of tooth decay skyrocket.  Flossing after meals can help prevent this bacteria from growing.

Alcohol
Since saliva plays an important part in the prevention of tooth decay, anything that dries out your mouth can be harmful to your teeth.  Alcohol often leads to a dried-out mouth, making for a dangerous dental environment.  This doesn't mean that cocktails are the only culprit; many medicines contain alcohol, as well.

Tea & Coffee
Tea and coffee permeate your tooth enamel and can cause your teeth to develop brown stains.  To avoid stains, try sipping your morning beverage through a straw or swishing your mouth out with water after your daily cup of joe.

Lemons
If you love the tart taste of lemons, it may be time to cut back.  Lemon juice is highly acidic and can cause the enamel on your teeth to erode.  Stick to low-sugar or sugar-free lemonade if you need a fix.

What about the good foods?  Here are 3 foods that will help keep your teeth healthy:
-Drink water regularly throughout the day. The water will wash away bacteria-producing foods and fluoridated water can prevent decay.

-Chew sugarless gum.  Chewing gum increases saliva production and will help prevent sugar cravings.  

-Dairy products, like cheese and yogurt, also help to increase saliva production.  Try choosing a low-fat string cheese instead of a candy bar when you get a snack craving.
