How to Prevent Cavities in Kids

Cavities are one of the most common chronic conditions in children—but they’re also one of the most preventable. At the dental office of Dr. Anne Lindley in Sunnyvale, TX, we’re passionate about helping kids build healthy habits early so they can enjoy strong, confident smiles for years to come. Here’s how to give your child the best defense against tooth decay.

1. Make Brushing and Flossing a Daily Routine

Consistency is key. Help your child brush their teeth twice a day with a fluoride toothpaste and floss once daily to remove plaque and food particles between the teeth. For younger kids, supervision is essential—most children need help brushing and flossing properly until at least age 6 or 7. To make it more fun, try letting them pick out their own toothbrush, use a brushing app, or set a timer with their favorite song.

2. Be Smart About Sugar and Snacks

Sugar feeds the bacteria that cause cavities, so it’s a good idea to limit sugary snacks and drinks—especially things like juice, soda, sticky candies, and even dried fruit. Offer water as the default drink, and choose tooth-friendly snacks like cheese, crunchy veggies, fresh fruit, and yogurt. It’s not just about what they eat—it’s when. Frequent snacking throughout the day gives cavity-causing bacteria more chances to do damage, so try to stick to mealtimes as much as possible.

3. Don’t Skip Dental Checkups

Regular dental visits every six months are one of the most powerful tools for preventing cavities. These checkups allow us to clean away plaque buildup, check for early signs of decay, and keep track of your child’s dental development. Dr. Lindley also uses these visits as a chance to educate and encourage kids—so they feel empowered to take care of their own smiles.

4. Ask About Fluoride and Dental Sealants

Fluoride helps strengthen tooth enamel and protect against decay. If your child needs a little extra protection, we may recommend a fluoride treatment during their visit. Sealants are another excellent option—they’re thin, protective coatings applied to the back molars, where food and plaque tend to collect. They can significantly reduce the risk of cavities in those hard-to-clean areas.

5. Start Early and Stay Positive

Your child’s first dental visit should happen by age one, or within six months of their first tooth. These early visits help your child feel comfortable in the dental chair and give you a chance to ask questions about brushing, teething, diet, and more. Keep things positive—kids pick up on your attitude, so the more relaxed and upbeat you are about dental care, the more likely they’ll be to build a healthy relationship with it, too.
