How To ... Save Your Tooth Enamel


The thin, hard outer layer of your teeth is what guards you from cavities and other painful problems. Here are tips from local dentists on protecting your enamel, beyond the obvious steps of limiting sweets and brushing, flossing and going for regular professional cleanings:

* Drink wisely. Certain beverages are full of acids and additives that wear away enamel, including soda (regular and diet), lemonade and sports and energy drinks. If you're a big fan, at least alternate them with water or low-fat milk.

* Drink quickly. Swallow liquids quickly or use a straw to limit contact with your teeth. Don't take big gulps and hold them in your mouth.

* Avoid too much snacking. Every time you eat, acids have a new chance to attack your teeth. If you must have a sugary treat, eating it with a meal is better than nibbling it on its own -- especially if you're nibbling several times a day.

* Balance your meals. Vegetables, fruits and whole grains are as good for enamel as they are for the rest of your body. Healthy foods such as low-fat cheese, chicken, nuts and milk also can counteract more acidic choices such as yogurt, grapes, lemons, citrus fruits and tomatoes.

* Treat chronic heartburn. Stomach acids that travel up your throat can cause significant damage to your teeth. Repeated vomiting by people with eating disorders has the same effect.

* Chew sugarless gum. Brands with the ingredient xylitol are especially good at boosting the flow of saliva, which helps protect teeth.

* Take aspirin correctly. Unless a doctor has specifically told you to chew up pills, swallow them whole with water.

* Schedule tea time. Black and green teas -- but not herbal teas -- contain substances that can curb the growth of harmful bacteria in the mouth (although they also can cause staining over time).
