The teen years are key years for orthodontics and post-braces care, as well as good nutritional habits. So your dentist is a crucial part of your teenager's health care team. Today's teenagers are especially at risk for tooth decay caused by soda, sugar and constant snacking. Soda contains acid as well as decay-causing sugar. Teens also love sour candies, which are sugardy, acidic and often gummy so they stick to crevices in teeth. Your dentist can be a powerful ally in reminding teens that good nutrition as well as good at-home dental hygiene habits, along with regular dental checkups, can help you have the smile of your life.
