Tooth-Whitening Products
Some toothpastes claim to whiten teeth. There's nothing wrong with using whitening toothpastes as long as they also contain fluoride and ingredients that fight plaque and tartar. But these toothpastes alone don't contain much in the way of whitening ingredients and probably won't noticeably change the color of your teeth.
It's easy to be lured by ads telling people they need gleaming white teeth. But these ads are really targeted to older people. The truth is that most teens don't need tooth whitening because teeth usually yellow as a person gets older. If you think your teeth aren't white enough, though, talk to your dentist before you try any over-the-counter whitening products. Your dentist may be able to offer you professional treatment, which will be suited to your unique needs and will work better than over-the-counter products.
Be careful when buying over-the-counter whitening products. Some bleaching agents may damage your gums and mouth. So always follow the instructions on any whitening product you use.
The Nutrition Connection
Eating sugar, as you probably already know, is a major cause of tooth decay. But it's not just how much sugar you eat - when and how you eat it can be just as important to keeping teeth healthy.
When you eat sugary foods or drink sodas frequently throughout the day, the enamel that protects your teeth is constantly exposed to acids. Hard candies, cough drops, and breath mints that contain sugar are especially harmful because they dissolve slowly in your mouth. Many experts suggest that you take a 3-hour break between eating foods containing sugar.
Sugary or starchy foods eaten with a meal are less harmful to your teeth than when they're eaten alone, possibly because the production of saliva, which washes away the sugar and bacteria, is increased. Eating sugary foods before you go to bed can be the most damaging (especially if you don't brush your teeth afterward) because you don't produce as much saliva when you sleep.
For most people, it's hard to cut out sweets completely, so try to follow these more realistic guidelines:
Eat carbohydrates (sugars and starches) with a meal.
If you can't brush your teeth after eating, rinse your mouth with water or mouthwash, or chew sugarless gum.
Don't eat sugary foods between meals.
If you snack, eat nonsugary foods, such as cheese, popcorn, raw veggies, or yogurt.
