The extent to which foods stick to the teeth is directly proportional to the risk of tooth decay. In other words, the more a food adheres to the teeth and the longer it remains before being cleaned away, the higher the likelihood of cavities forming. This is why diets high in carbohydrates increase the risk of tooth decay. Among all sugars, the most harmful for both dental and overall health is sucrose, commonly known as table sugar. Instead of products containing refined sugars, it is better to choose more natural options. For example, snacks offered to children should not be packaged products. Fresh or dried fruits and nuts are preferable. If packaged foods are given, they should be offered in moderation, immediately after meals, and followed by proper oral cleaning about half an hour later. This half-hour period allows the mouth to naturally balance its pH.
Some foods can help prevent tooth decay. Apples, carrots, and peanuts assist with mechanical cleaning of the teeth and also stimulate saliva flow, which helps wash the mouth. Cheese also increases saliva production, further aiding in the natural cleansing effect.
Foods high in fiber leave very little residue on the teeth and can help remove other sticky foods to some extent. After meals and between snacks, fibrous foods such as apples, oranges, and celery can be preferred over sticky foods. Foods that promote cavities, such as cookies, cakes, crackers, and biscuits, should be consumed alongside cavity-preventive foods like cheese and milk. Meals should ideally end with cheese, as it reduces demineralization, the process of tooth breakdown. Fruit juices and acidic drinks, if consumed, should be taken before cheese.
