Preventing cavities in kids: What every parent should know

Did you know that 20% of children ages 6-8 have at least one untreated cavity.

These cavities aren’t just uncomfortable – they can make eating, speaking, and learning more difficult. In fact, children with poor oral health tend to miss more school and often earn lower grades than classmates with healthy teeth and gums.

The good news? Cavities are preventable and healthy habits can start early.

How to care for your baby’s teeth

Your baby’s first teeth may be small, but they play a big role in helping your child develop. They also guide permanent teeth into place, so keeping them healthy is essential.

Tooth decay can begin as soon as teeth appear – making early care a must. Here are simple steps to help protect your baby’s oral health:

  • Clean your baby’s gums with a soft, damp cloth after feedings – even before teeth come in.
  • Start brushing with a small, soft-bristled toothbrush as soon as the first tooth appears. Use a small amount of fluoride toothpaste (about the size of a grain of rice).
  • Schedule your child’s first dental visit by their first birthday or within six months of their first tooth appearing.

Why do kids need dental sealants?

Even with regular brushing and flossing, the grooves in your child’s back teeth can be difficult to clean. That’s where dental sealants come in.

Sealants are thin, protective coatings applied to the chewing surfaces of the back teeth. They act as a barrier, keeping food and bacteria out of areas most prone to cavities.

According to the Centers for Disease Control and Prevention (CDC), sealants can prevent 80% of cavities when applied as soon as the back teeth (also called molars) come in. Permanent molars come in around ages 6 and 12.

Sealants can provide protection that lasts for years.

Building healthy habits as kids grow

As children get older and begin brushing on their own, here are tips to help them maintain a healthy smile:

  • Brush twice daily with fluoride toothpaste.
  • Schedule dental checkups every six months.
  • Make flossing a part of the daily routine.
  • Encourage your child to eat nutritious meals and limit sugary drinks and snacks.

Why regular dental visits matter

You can reinforce good dental care by taking your child to the dentist every six months. Regular visits help prevent cavities and other oral health issues before they become serious.

Establishing a consistent dental care routine at home and with your dentist sets your child up for a lifetime of healthy smiles.

The American Dental Association recommends scheduling your child’s first dental appointment within six months after the first tooth appears. Capital Blue Cross members can call Member Services (using the back of your ID card) or use our online provider search tool, MyCare Finder.
