It's vital to teach your children how to brush and floss their teeth in order to prevent cavities. In fact, start teaching your children to brush their teeth as early as possible. At first, just wet the toothbrush. As soon as teeth start to come through, use the tiniest amount of toothpaste--no more than a dot.  By the time the child is three years old, increase to a size of a pea.

Brush gently all around your child's baby teeth -- front and back. Brush your baby's teeth yourself until they can hold the toothbrush fairly well. At about the age of 6, they can brush, spit and rinse on their own and may just require the reminder to brush their teeth twice a day.
