Kids these days are at greater risk from acid erosion than ever before with advent of ubiquitous fizzy and fruit drinks. Acid erosion is a serious dental problem, which leads to indentations of the teeth. There are a number of ways to help kids avoid it: don't swish drinks around your mouth; if you do have a fizzy drink, use a straw; don't brush your teeth immediately after having a fizzy drink as this is when the enamel is softest; and go for regular check-ups. Sensodyne Pronamel for Children, used twice daily with a medium-soft toothbrush, can also help. www.pronamel.com
