Good oral hygiene significantly reduces your child’s risk of developing cavities. Brushing helps remove the food sources that feed the bacteria that cause cavities. It is important to gently brush all tooth surfaces [and gums] for 2-3 minutes, using a circular motion and holding the brush so the bristles are at a 45 degree angle toward the gumline. To make sure they do a good job, help your child brush until they are at least six years old. Brush your child’s teeth after each meal or at least twice a day, especially at bedtime.
