It is the nature of children to love sweets, but parents know that eating too many sweets is not good for their children’s teeth and can easily cause dental caries. Caries is the most common chronic non-communicable disease in the world, and a large number of studies have shown that sweets are a major factor in causing caries. When small children eat sweets or drink a variety of sugary beverages, the bacteria on their teeth utilize the sugar in the food to produce acid, which causes corrosion of the teeth. Frequent intake of sweets will prolong the acid corrosion time on the teeth, reducing the protective capacity of the tooth surface. Authoritative experts pointed out that the oral bacteria decomposition of sugar produced by the acid will hurt the enamel on the surface of the teeth, the formation of cavities, the need for fillings, serious and even need to extract the teeth, reduce the sugar can effectively reduce the acid damage to the teeth. But completely prevent children from eating sugar is impossible, recently the American Academy of Pediatric Dentistry announced the impact of different types of sweets on the teeth, it is worthwhile to learn. 1, the best not to eat sweets the best not to eat sweets include bubble gum, gummy candy, sour fruit candy, caramel candy. Sticky, chewy candies can get stuck in the cracks between teeth, making it difficult for saliva to remove them, which can lead to tooth decay. Sour fruit candies have a higher acid content, which is more damaging to tooth enamel and makes teeth more susceptible to bacterial attack. 2, better sweet choices Better sweet choices include milk chocolate, graham crackers, pretzels, and so on. These sweets are less acidic and less sticky, making them less harmful to teeth than gummy candies, bubble gum, and sour fruit candies. However, since dental health depends not only on what is ingested, but is also closely related to the frequency of intake, it is important to limit the total amount of snacks consumed. 3, the best sweet choices The best sweet choices include dark chocolate and sugar-free gum. Dark chocolate contains antioxidants including tannins, polyphenols and flavonoids, which can play a role in inhibiting bacteria from adhering to the teeth, preventing gum infections and preventing tooth decay. Xylitol sugar-free gum helps promote the growth of tooth-protecting, non-acid-producing bacteria to inhibit bacteria and plaque formation.
