Plaque starts to grow on teeth as soon as they appear.
So the simple answer is start brushing your child's teeth as soon as they appear.
Starting a child's dental hygiene from the earliest time is a great lifelong lesson.
Be sure to use a super soft brush and they will put it in their mouth without much prompting.
Being a role model for your children is the best way to get them started into good dental habits.
