Did you know that certain foods have oral health benefits for kids? Whether they help naturally brush away plaque and bacteria or provide enamel-strengthening nutrition that helps prevent cavities, there are countless super foods out there your child’s smile can benefit from. Read on to learn five accessible tooth-healthy foods that are great in packed lunches!

Cheese Sticks & Yogurt

Dairy products like cheese sticks and yogurt are full of bacteria that are good for your child, as well as rich in calcium. These probiotic-packed treats can help fight off bad oral bacteria that can lead to cavities, support gum health, and even strengthen teeth. Try to choose yogurts that are sugar-free to avoid the increased risk of decay.

Mixed Nuts & Trail Mix

Nuts, trail mixes, and seeds are all high in protein and include key minerals such as calcium, phosphorus, and magnesium, which are known to help build strong teeth and bones. If your child isn’t a fan of nuts and seeds on their own (or trail mix), you can always add them to a yogurt to make a parfait or as a crunchy topping for a salad or snack.

Leafy Greens

Leafy greens like spinach, kale, and lettuce are full of fiber and various vitamins, such as A, C and K. These help support health gums and teeth and are all-around necessary nutrients for growing children! If your child isn’t a fan of leafy greens on their own, you can sneak some into a breakfast smoothie before they go to school or add them to pasta or soups. A good tip is if it’s blended, whether that’s in a smoothie or a sauce, they’re less likely to turn it away!

Crunchy Fruits & Vegetables

Fresh fruits and vegetables are nature’s toothbrush! Nutrient-dense crunchy foods like apples slices, celery sticks, and carrots naturally remove plaque and bacteria from the surface of your child’s teeth as they are chewed on, helping reduce risk of cavities. They can also be paired with protein-packed peanut butter, ranch dressing, or other condiments that make them a more appealing treat for kids.

Protein

Just like with adults, protein is an important part of your child’s diet, especially when it comes to their oral health! Eggs, chicken, and pork help protect and rebuild tooth enamel, as they tend to be low in sugar and high in calcium, protein, and phosphorus, which helps support overall growth in children.
