55. When should kids start flossing?

Your child should start flossing as soon as they have two teeth that touch, which usually happens around ages 2–3. Flossing gets rid of plaque and food particles that a toothbrush can’t reach, helping prevent cavities and gum issues.

Getting started:

At first, parents should floss for their child to make sure it’s done gently and thoroughly.
As your child grows and gains coordination (around 7–10 years old), they can start flossing on their own — with supervision to make sure it’s done right.

Starting early builds good oral hygiene habits that last a lifetime!
