Hi ladies, Pls. go thru this. might be useful, which i would like to share with all! dolet me know your comments! a student's science fair project is demonstrating cola's ability to eat through tooth enamel. It's not pretty. But soda isn't the only food that does a number on your grin. Here are some of your smile's worst enemies -- and best friends. THE ENEMIES LIST Soda, fruit juice, and sports drinks Not only are they sugary, they're acidic, and that creates a perfect home for the bacteria that cause cavities and gum disease -- especially if you tend to sip on one or another of these drinks all day (who, us?). Acid-neutralizing saliva just can't keep up. The realistic fix Nobody's saying go cold turkey but for all-day swigging, choose water. Reserve these pick-me-ups for once-a-day use. And buy some straws -- sipping through them shrinks teeth-exposure time. Sticky stuff We're not just talking gooey caramels or fruit rollups. Bread, crackers, chips, sweet rolls, and other refined carbohydrates are nearly as likely to cling to teeth as a Tootsie Roll -- and they hang on for at least 20 minutes. Not good. The realistic fix Try to say no to sticky sweets and carbs when you can't brush afterward. Alternatively, slosh some water around in your mouth or chew a stick of sugarless gum that's sweetened with xylitol. The gum helps remove sticky food particles from your teeth, and xylitol curbs cavity causers and increases healthy saliva. YOUR SMILE'S BEST FRIENDS Cheese, please Eating a bit of cheddar (or whatever) at the end of a meal helps protect teeth. It stimulates the production of cleansing saliva, plus the calcium in cheese helps harden teeth. Crunchy things Crisp apples, celery and carrots are nature's little toothbrush alternatives. Not only do they help rid your mouth of food particles but their rough, fibrous texture actually scrubs away as you chew, slightly brightening your smile. Have a cuppa Drinking tea after eating can help destroy the germs that cause cavities, gum disease, and phewy breath. That goes for both green and black teas. Shiitake mushrooms These delicate, delicious flavor-boosters contain lenitan, a plant substance that's anything but a lightweight: It fights both tooth plaque and the bacteria that live in it.
