In recent years, childhood caries, abnormal tooth development and eruption have become increasingly common. Children’s diet not only affects their dental and oral health, but also affects their overall healthy development. We need to recognize the importance of “healthy diet education”, which means a balanced diet. A healthy diet provides children with all the nutrients they need to grow. A balanced diet should include the following major food groups: fruits, vegetables, grains, meats, legumes, and dairy products. How does a child’s diet structure affect oral health? 1. Children need a balanced diet so that their teeth can grow in a healthy manner. 2. To have healthy gum tissue, it is also important to maintain a balanced diet. 3. It is also important to know that some diets contain too much of certain carbohydrates (such as sugar and starch), which can increase the chance of tooth decay in children. How to develop a safe diet structure? First of all, make sure that the diet is balanced. Then pay attention to the frequency of sugar and starchy food intake. Starchy foods include bread, crackers, pasta, pretzels, and snacks like chips. When looking at “sugar”: look beyond the candy jar – many foods contain one or more sugars, and all sugars can cause tooth decay. Fruits, some vegetables and most dairy products contain sugar (at least one). Many processed foods contain sugar, although some sugary foods do not taste sweet. For example, in a peanut butter and jam sandwich, the sugar is not only in the jam, but may also be in the peanut butter. Sugar is also found in some condiments, such as ketchup and salad dressings. Should you keep your child away from all sugary, starchy foods? Of course not! Many sugary and starchy foods provide the nutrition your child needs. Here’s what you should do: choose your food wisely and feed your child. Foods containing sugars and starches are safer for teeth when eaten at three meals (rather than as a snack). Sticky foods like dried fruit and toffee are hard to wash off the teeth with saliva, water or milk, so they are more likely to rot the teeth than foods that can be quickly cleared off the teeth. Talk to your pediatric dentist to find out how food choices and intake can protect your child’s oral health. Is there any advice for children who are still breastfeeding? 1. Promote breastfeeding: breast milk is high in calories and rich in various nutrients and more enzymes and antibodies needed by infants and young children, which is beneficial to infants’ digestion, absorption and resistance to diseases. Direct breastfeeding is convenient, hygienic and economical, and it is recommended to exclusively breastfeed for at least 6 months. From the perspective of maternal and child health, it is advocated to breastfeed on demand until 2 years old. It should be noted that irregular breastfeeding or sleeping with nipples for a long time will increase the risk of dental caries in children. 2, artificial feeding precautions: in the absence of breast milk or breastfeeding mental stress and other situations, artificial feeding should be taken. Bottle is the tool of artificial feeding. When bottle feeding, you should choose the pacifier suitable for infant’s age to avoid that the milk flows too fast because the hole is too big and the infant does not need to suck to flow out, so that the chewing muscle does not get the proper exercise; it is better to hold the infant when feeding, parents hold the bottle and do not press the bottle against the upper front teeth to avoid affecting the jaw development; improper bottle feeding is very likely to lead to infant’s dental caries, infant should not hold the bottle with milk or other sweet drinks at any time bottle with milk or other sweet drinks as a placebo at any time, especially when sleeping; parents should encourage their children to drink from a cup after the child is 1 year old. Parents should go to children’s dentistry for examination and treatment if they find any disease such as dental caries, swelling, pain, abnormal development, etc. Besides, if they find any sign of developmental delay, they should go to dentistry hospital if there is no special problem in pediatric examination. Some other tips on the structure of your child’s diet and oral health: 1. Ask your pediatric dentist to help evaluate your child’s diet structure. 2. Be mindful when shopping. Don’t keep sugary or starchy snacks in the pantry, buy those only when they are special. 3.Limit the number of snacks; choose nutritious snacks. 4.Provide balanced recipes, with sugary and starchy foods only at three meals. 5.Don’t give your baby all sweet drinks such as milk, formula or juice when you put them to bed. 6.Children chew gum and drink carbonated drinks, choose sugar-free.
