Be sure that your child brushes his teeth at least twice a day with fluoride toothpaste. Flossing daily is also important, because flossing can reach spots between the teeth that brushing can't. Check with your pediatric dentist about a fluoride supplement which helps tooth enamel become harder and more resistant to decay. Avoid sugary foods and drinks, limit snacking, and maintain a healthy diet. And finally, make regular appointments so that we can check the health of your child's teeth and provide professional cleanings.
