• Healthy Snacks to Prevent Tooth Decay in Kids

    image You may often find yourself giving your child snacks between meals or in the school lunchbox, but can snacking promote tooth decay? Which foods are teeth-friendly and which ones should you avoid the next time your child craves a little snack?

    Understanding Tooth Decay

    Bacteria live in our mouths. When we feast, so do bacteria. Bacteria particularly enjoy breaking down sugars and starches left on the teeth, which leads to the formation of plaque and acid. Acid created by bacteria can damage the teeth if left on the tooth surface for 20 minutes or more. This can lead to tooth decay.

    Sticky and Sweet: A Good Treat?

    When selecting snacks for your child, read the ingredient label to find out if the snack contains sugars or starches. Select snacks that are sugar-free or unsweetened. Some sugary snacks and drinks to avoid include:
    • Candies
    • Mints
    • Cookies
    • Pastries
    • Soda and juices
    If you do decide to give your child a sugary treat, do so at mealtime rather than as a snack. For instance, after dinner you can serve your child a dessert. More saliva is usually generated around mealtime, which makes it easier for food to be washed away from tooth surfaces.
    Sugary foods may be obvious tooth decay culprits. But sticky, chewy snacks can also lead to tooth decay. Foods like granola bars, raisins, oatmeal, and peanut butter tend to linger on the teeth longer and are not easily washed away by saliva. This does not mean that you should avoid giving your child these foods, simply encourage your child to brush after a chewy snack.

    Teeth-Friendly Snack Options

    Here are some snack options for your child that are both teeth-friendly and healthy:

    Fruits and Vegetables

    Give your child fruits and vegetables that have high water content, like:
    • Melons
    • Pears
    • Celery
    • Cucumbers
    Limit those that are high in concentrated sugars. (Yes, fruits and vegetables do contain natural sugars.) Some fruits to limit include bananas and raisins. Also encourage your child to brush after eating fruit with high concentrations of sugar.


    Low-fat cheese is a good snack option since it triggers the flow of saliva. Examples include:
    • Monterey Jack
    • Cheddar
    • Swiss


    Soda, juice, and milk contain sugar. While milk is important for a growing child, juice and soda can be replaced with water. Water will not harm teeth and will help rinse away food particles. Fluoridated water is also ideal for preventing tooth decay in children 12 years old and under. Check the label on bottled water to see if it contains fluoride. For young children, plain water at bedtime is a good choice instead of formula, milk, or juice, which can damage teeth overnight.

    Other Healthy Teeth Tips

    • Limit snacking. Snacking between meals limits the amount of time saliva has to wash away food. This means more food remains in the mouth for bacteria to process. If possible, limit snack time to no more than 1-2 times a day.
    • Brush teeth. Have your child brush their teeth with fluoride toothpaste twice a day. Your child should also brush or rinse after every snack and after taking medications, since they may contain sugar. It is also a good idea to floss at least once a day. If brushing or flossing is not possible, have your child rinse with water after snacking to wash away food particles. Flossing should start when your child has 2 teeth that touch each other.
    • Build strong teeth. Give your child foods that will build strong teeth, like broccoli, plain yogurt, and milk.
    • See the dentist. Schedule regular dental check-ups for your child. Their first appointment should occur before their first birthday.
