A Parent’s Guide to Flossing Children’s Teeth

Healthy oral hygiene habits start early—and flossing is a key part of that routine. At Greater Houston Pediatric Dentistry, we’re here to support parents in helping their children build a strong foundation for lifelong dental health.

The American Academy of Pediatric Dentistry recommends children visit the dentist by their first birthday. The earlier good habits are introduced, the more likely children are to carry them into their teenage and adult years.

Why Flossing Matters for Children

Brushing alone doesn’t reach all the surfaces of the teeth—about 40% of each tooth’s surface can’t be cleaned by a toothbrush alone. That’s where flossing comes in.

Flossing helps remove plaque and food particles from between the teeth and just under the gumline, protecting your child’s mouth from:

• Tartar buildup

• Gum inflammation

• Cavities

• Bad breath

By flossing daily, your child’s mouth will feel fresher, and their risk for dental problems will significantly decrease. Even better, they’ll be building positive oral hygiene habits that will serve them well as they grow.

When To Start Flossing Your Child's Teeth

Start flossing as soon as two of your child’s teeth begin to touch—this usually happens between the ages of 2 and 6. At this stage, parents will need to do the flossing, but it’s also a great time to connect with your child, teach them the importance of cleaning between their teeth, and maybe even sing a song.

As your child grows and develops more independence, encourage them to take on flossing themselves—at first, with your supervision to ensure they’re doing it effectively.

Tip for Parents: Stay involved even when your child starts flossing on their own. Good habits are easier to form—and harder to break—when started early and done correctly. Parents and caregivers can even floss at the same time as their child(ren). It is always helpful for children to see that we are practicing what we preach!

How To Floss Your Child's Teeth

Here’s a simple step-by-step guide:

1. Use about 18 inches of floss, or choose a floss pick for easier handling.

2. Wrap the floss around your middle fingers, and use your thumbs and forefingers to guide it.

3. Gently slide the floss between the teeth, curving it into a “C” shape around each tooth to reach just under the gumline.

4. Move the floss up and down gently several times.

5. Repeat for each tooth.

6. Rinse and spit—a favorite part for many kids!

Pro Tip: Choose a calm time of day for flossing—before bedtime or after a bath—to make it a relaxed, positive experience.
