Chewing hard foods is good for your dental health. Hard foods take more chewing, which stimulates the production of more saliva. Saliva has many benefits for your teeth. It kills harmful oral bacteria, neutralizes harmful acid, and supplies minerals that help teeth stay strong.
Many hard foods are also good meal-finishers that can clean your teeth when you eat them. Of course, sugar-free gum is a good choice after eating, because it cleans your teeth, removing food debris and bacteria. Carrots, celery, and apples can have a similar effect. Ending a meal with these types of foods can be almost as effective as brushing your teeth after eating, and in some ways it’s better for you.
You might not be able to get your child to brush their teeth after lunch, but ending lunch with a tooth-cleaning food might be more reasonable.
