When to Start Flossing and Teaching Kids How to Do It: A Guide for Parents

in Jun 11, 2025

Flossing is an essential part of maintaining oral hygiene for everyone, including children. While brushing helps clean the surface of the teeth, flossing reaches the areas that a toothbrush can’t, like between the teeth along the gumline. Parents often wonder when to introduce flossing to their kids and how to make it a habit. In this guide we will come to when children should start flossing.

When Should Children Start Flossing?

People often ask when children should start flossing. The American Dental Association recommends introducing flossing to children as soon as their teeth start to fit closely together; this typically occurs around the ages of 2 or 3. This is very important because flossing helps remove food particles and plaque that brushing alone can’t reach. Starting early also helps them to make it a lifelong habit. Here are some key points mentioned:

  • Kids' flossing age typically starts around 2 or when teeth touch. 
  • Since toddlers lack the motor skills to floss on their own, parents should help them learn properly.
