At school, children should rinse their mouth with water after meals, leaving their teeth free of sugar and acid. At home, encourage children to drink tap or fountain water. Soda should be used when drinking straw, sugar away from the teeth. If you buy bottled water, make sure it is fluoridated. Remember, bottled fruit juices are not a good choice due to the high sugar content. Regular dental examinations, combined with fluoride toothpaste brushing will also help protect children's teeth.
