When Should Children Start Brushing Their Teeth?

A structured overview of what credible sources and parent perspectives commonly say about this topic.

Quick answer

The American Academy of Pediatrics and dental experts recommend starting to brush a child's teeth when the first tooth erupts, usually around 6 months old. Parents should use a soft-bristled toothbrush with a smear of fluoride toothpaste and assist their child until they can brush independently, typically by age 6 to 8.
