Cavities, or dental caries, are among children’s most common chronic conditions, yet they are largely preventable. With the proper habits and guidance, parents can help their kids build intense oral hygiene routines that will protect their smiles for years.

At Square One Health Group, we believe prevention is the key to lifelong dental health. Here’s how to help your child avoid cavities and develop a healthy relationship with dental care.

What Causes Cavities in Kids?

Cavities occur when the natural bacteria in the mouth interact with sugars and starches left on teeth, creating acids that erode the enamel. Over time, this erosion leads to holes or cavities in the tooth. Kids are especially vulnerable to cavities due to thinner enamel, sugary diets, and developing brushing habits.

Why Early Oral Care Habits Are Essential

Good dental habits during childhood help set the stage for a lifetime of healthy smiles. Children who learn to brush and floss correctly are less likely to develop cavities, gum disease, or other oral issues later in life. Early dental visits help reduce fear or anxiety about seeing the dentist.

10 Effective Ways to Prevent Cavities in Children

1. Start Brushing Early

Clean your child’s mouth before their first tooth appears by wiping their gums with a soft cloth. As soon as the first tooth erupts, switch to a soft-bristled toothbrush and a tiny smear of fluoride toothpaste. Brush twice a day — every day.

2. Use the Right Amount of Fluoride Toothpaste

Fluoride strengthens tooth enamel and helps prevent decay. Use a grain-of-rice-sized amount of toothpaste for children under 3, and a pea-sized amount for children ages 3 to 6. Always supervise brushing to ensure your child spits out excess toothpaste.

3. Introduce Flossing Early

Once your child has two teeth that touch, it’s time to start flossing. This helps remove plaque and food debris from between teeth where a toothbrush can’t reach. Floss picks or kid-friendly flossers make it easier and more fun.

4. Limit Sugary Foods and Drinks

Frequent snacking or sipping on sugary beverages can feed harmful bacteria in the mouth. Try to reduce your child’s intake of:

• Juice and soda
• Candy, cookies, and other sweets
• Sticky snacks like dried fruit

Encourage water and healthy snacks like cheese, apples, and veggies instead.

5. Avoid Bedtime Bottles with Milk or Juice

Letting your child go to bed with a bottle of milk or juice can cause sugars to sit on the teeth all night, leading to “baby bottle tooth decay.” Only water should be offered at bedtime if a bottle or sippy cup is needed.

6. Encourage Drinking Tap Water

Fluoridated tap water provides extra cavity protection. If your local water does not contain fluoride, consult your dentist about supplements or other sources to help strengthen your child’s enamel.

7. Schedule Routine Dental Visits

Your child should visit the dentist by their first birthday or within six months of the first tooth erupting. Regular checkups every six months allow dentists to monitor development, catch issues early, and provide cleanings that help prevent decay.

At Square One Health Group, we make dental visits positive and stress-free, helping children look forward to their appointments.

8. Ask About Dental Sealants

Sealants are thin, protective coatings applied to the grooves of back teeth, where cavities often form. They can significantly reduce the risk of decay and are especially helpful for school-aged children.

9. Model Good Oral Habits

Kids are more likely to brush and floss regularly if they see you doing it too. Make oral care a family routine by brushing together, celebrating good habits, and discussing why dental health matters.

10. Make Oral Care Fun

Turn the Brush into a game or story, use kid-friendly and flavoured toothpaste, and consider using brushing apps or reward charts. Creating a positive experience makes kids more eager to care for their teeth.

Signs Your Child Might Have a Cavity

Even with great habits, cavities can still develop. Keep an eye out for:

• Sensitivity to hot or cold
• Complaints of pain when chewing
• Dark spots or holes on teeth
• Swollen or red gums
• Avoiding certain foods

If you notice any of these, don’t wait — early treatment prevents the cavity from worsening.
