The World Health Organization (WHO) in 2001 put forward the “8020” plan, that is, the age of 80 years old should also have 20 sound teeth. However, in order to have a mouthful of good teeth, must start from a young age in the “eat” word on the effort, must pay attention to the baby to strengthen all aspects of nutritional intake. After the baby was born 4 to 10 months after the start of milk teeth, 1 year old erupted 6 to 8, 2 years old to 2 and a half years of age out of all, up to 20. Experts remind us that during the teething period, complementary foods and a balanced diet are crucial to the healthy development of teeth. Timely and correct addition of complementary foods can not only provide the necessary nutrients for the development of teeth, such as calcium, phosphorus and other minerals and many vitamins, to promote the growth of teeth. It also helps babies to practice chewing and digestion, and even helps to develop their language skills. Enhance calcium and phosphorus intake Calcium is a major component of teeth, and adequate intake of calcium will result in strong teeth. Milk and bean products are the richest in calcium, especially dairy products, which have the right ratio of calcium to phosphorus and are easily absorbed by the body. Cooking calcium-rich foods, put some vinegar, which helps dissolve calcium and facilitate the body’s absorption and utilization. Eating citric acid-containing fruits (such as lemons, oranges, plums, etc.) can also help calcium absorption. Phosphorus is an indispensable nutrient to keep the teeth solid, widely distributed in food, as long as not partiality, can take in rich phosphorus. Vitamin D can promote the body’s absorption of calcium and phosphorus and ossification to ensure the healthy development of teeth. Animal liver and cod liver oil are rich in vitamin D, and can be consumed appropriately. Intake of adequate amount of vitamin C Adequate amount of vitamin C is an important measure to prevent dental disease, if lack of it, can lead to periodontal disease. The human body cannot synthesize vitamin C. At the same time, the body’s storage of vitamin C is also limited, so it is necessary to take in vitamin C-rich foods every day. Vegetables contain a variety of trace elements and rich in vitamin C, is not to be ignored dental care food. If possible, you can also supplement the right amount of fruit (such as oranges, lemons, etc.) every day. Eat more dietary fiber Dietary fiber is widely found in vegetables, roughage in the dental care nutrients. Eat more rough food of appropriate hardness, can increase the self-cleaning effect of the teeth and gums massage effect, thus increasing the dentition and periodontal tissues of disease resistance. Such as yams, soybeans and other coarse grains, its phosphorus content is higher than fine grains, can promote the normal development of teeth, enhance the resistance to caries, so you can always eat; at the same time, due to eating coarse grains, must be chewed and swallowed slowly, so as to promote salivary secretion, reduce the adhesion of food and the formation of plaque, and play a role in dental care. Eat less sugar, pay attention to oral hygiene Sweet, soft refined food due to its high sugar content, but also easy to stay in the teeth, bacteria can use sugar to produce acid and corrosion of the teeth, it should be eaten less. Scientific consumption of carbohydrate foods, for example, eating sugary foods between meals, and not eating sugary foods before going to bed and after brushing your teeth. Do not eat excessive amounts of strongly stimulating (e.g., too acidic, too spicy, too hot, too cold) foods, either, to avoid damaging your teeth. Always rinse your mouth or brush your teeth after eating sweets or apples.
