Dental decay has been linked to sweet and acid foods. Plaque bacteria in the mouth change sweet food into acid, which causes tooth decay. It is very important to reduce the number of times per day that decay producing food or drink is taken. Children at high risk for decay need to have gaps between meals, so they only eat five times a day. This reduces the amount of acid in the mouth. Drinks of water and milk are welcome between meals because they reduce acid on the teeth.
Tooth-damaging foods and drinks are: sweetened drinks such as juice, cordial, Milo, Quick, Ribena, sports drinks, soft drinks (including sugar free drinks), and sweet foods including dried fruit, fruit fingers, honey, jam, Nutella or muesli bars. Having these between meals or at school causes cavities. Children will remain at high risk if their diet is not modified.
Frequent consumption of fruit between meals can damage tooth enamel, as fruit can be acidic. When children eat fruit between meals, It is advisable that they follow up with a small square of cheese or a drink of milk or water, as this washes out the acidity from the mouth.
Tooth-friendly snacks are: rice cakes, dry biscuits, popcorn, nuts, cheese slices, peanut butter, vegemite, butter, cut-up vegetables with dips such as tzatsiki or hummus. For a healthy, balanced diet, children need three pieces of fruit and five vegetables a day, as well as a high intake of grains and protein, and three intakes of dairy products.
Before going to bed the child should clean their teeth with a toothbrush and toothpaste (a pea-size ball of low fluoride toothpaste for children under 7 years of age), and then have nothing to eat or drink other than water.
