Children love to eat, be careful of tooth decay What foods can prevent tooth decay

As the saying goes, "A toothache is not a disease, it hurts really badly". Suffering from tooth decay is also difficult, it will not be cured for a while, children like to eat snacks, and snacks are easy to cause tooth decay, let's take a look at what kind of foods can effectively help us prevent tooth decay.

1. Shiitake mushrooms

Shiitake mushrooms are the best at preventing tooth decay. First of all, the "mushroom queen" shiitake mushroom contains mushroom polysaccharides, which can inhibit the growth of pathogenic bacteria in the mouth, prevent the formation of dental plaque, and prevent tooth decay.Secondly, shiitake mushrooms also contain a source of vitamin D (ergosterol), which is a source of vitamin D (ergosterol) that is lacking in general vegetables, and ergosterol can be converted into vitamin D by sunlight, which can enhance the body's immunity and help children grow bones and teeth. Each 100 grams of dried shiitake mushrooms contain 7.8 grams of crude fiber, just like a "toothbrush" for healthy teeth, mechanical friction with the tooth surface when chewing, which can play a role in cleaning the teeth and reduce the formation of plaque. Shiitake mushrooms also contain the umami-flavored substances guanylate and shiitake mushroom extract, which have a fragrant smell and help to freshen the breath. In addition, it contains a large amount of vitamin C, which also has the effect of killing harmful bacteria and protecting teeth.

2. Celery

Celery has a lot of crude fiber, and eating celery can wipe off a lot of bacteria that adhere to the surface of your teeth. Repeated chewing of crude fiber foods can also stimulate saliva production to balance the pH level in the mouth.

3. Yogurt

Teeth are most afraid of the acidic environment in the mouth, and cheese is the best oral pH balance guard, which is rich in phosphate can neutralize the acidic substances in the mouth, which is not conducive to bacterial activity. There is also a large amount of calcium in cheese that is conducive to human absorption, which is good for both children's tooth growth and adult tooth strengthening.

4. Raisins

Surprisingly, sweet and sour raisins are also a good food for healthy teeth. American scholars said that raisins contain a variety of compounds that inhibit the growth of oral bacteria, oleanolic acid, oleanolic alanaldehyde, betulinol, etc., these chemicals are natural antioxidants in plants, which are beneficial to the health of teeth and gums, and can effectively prevent tooth decay, gingivitis and periodontitis.

Dietary precautions to prevent tooth decay

1. Carbohydrates in food

After fermentation, carbohydrates in food will provide heat and nutrients to the bacteria in the mouth, among which monosaccharides (such as brown sugar, white sugar, rock sugar, honey, fructose, glucose, lactose, etc.) are the most likely to cause tooth decay. Because the bacteria in the mouth will break down the sugar into glucose and fructose, and then polymerize the glucose together to become the matrix of plaque, so that the bacteria stick firmly to the surface of the teeth, and the fructose and a part of the glucose are fermented by the bacteria to produce organic acids to erode the teeth. Other carbohydrates, such as starches, are also broken down into sugars by amylase enzymes in saliva, which can also be fermented by bacteria to produce organic acids, but it takes a long time.

2. The acidity of the food itself

The acidity of certain foods can directly dissolve enamel and provide the acidic environment needed for bacterial growth, such as citrus fruits and carbonated drinks. In addition, long-term consumption of chewable vitamin C tablets will also cause damage to the enamel!

3. The content of fluorine

As we all know, fluoride is the most effective nutrient in preventing tooth decay! When the acidity in the mouth reaches below pH 5.5, the enamel of the tooth gradually dissolves, leading to the loss of minerals. However, if the acidity is diluted by saliva and the pH level rises, the dissolved tooth surface will begin to take up calcium and phosphorus from saliva and return it to the enamel, which is called recalcification.The presence of fluoride can promote the occurrence of recalcification, slow down the progress of tooth decay, and even restore the original healthy appearance of tooth decay that has not yet broken through in the early stage. In addition, low concentrations of fluorine inhibit the ability of bacteria to produce acids; Medium concentrations of fluorine can inhibit the growth and metabolism of bacteria; High concentrations of fluorine have a bactericidal effect. Fluoride is very small in food, and at present, 1ppM fluoride is added to tap water artificially, although the fluoride content is low and has no sterilization effect, but it can reduce the ability of bacteria to produce acid and reduce the number of tooth decay cases by 65%! However, if the concentration is too high, it will react, causing brown spots on the teeth to appear and permanently cannot be removed, which is very unsightly!

4. How much food stimulates saliva secretion

Saliva contains a lot of water, which can rinse away food and bacteria left on the surface of the teeth, and at the same time act as a buffer to neutralize some of the acids produced by bacteria. In addition, saliva contains calcium and phosphorus, which can promote recalcification of the decalcified tooth surface, which can help prevent tooth decay. There are also some immunoglobulins in saliva, which can be antibacterial and protect the mucous membranes and teeth in the mouth. The best example of this is yoghurt, which not only stimulates saliva production, but also neutralizes the acid in the mouth with its high protein content, and can also promote recalcification with high calcium and phosphorus ingredients.

5. The texture of the food

Sticky food sticks to the teeth, which will continue to provide raw materials for bacteria to make acid, which will increase the time it takes to erode the enamel. High-fibre foods can reduce tooth decay, especially lettuce, because they don't stick to your teeth and require more strenuous chewing, which stimulates more saliva production. So if you can't brush your teeth immediately after eating, you can put this type of food at the end of each meal, or drink water to clean your mouth. Hard foods require more vigorous and repeated chewing, which can promote blood circulation in the tooth flesh, strengthen the periodontal ligament, help bone resorption in the bone socket and the formation of new bone, and prevent periodontal disease. And it can stimulate a large amount of saliva secretion at the same time, which is good for oral health!

Tips for relieving tooth decay

1. Eggplant Fang ("Famous Recipe on the Sea") autumn eggplant flowers, dried ash burning, sore spots; Or pound the juice with eggplant root and apply it frequently: or mix it with eggplant stalk ashes, or add equal parts of eggplant ash to fine spices, and add them to the caries.All of the above use yellow eggplant (yellow skin color). It is said to have "immediate effect". Efficacy: Relieve caries pain. Tooth decay is indicated.

2. Ash polyester vegetables (also known as ash, golden locks) burn ashes, water is flooded into pills, detoxified and wrapped, and filled into caries holes. Efficacy: Filling cavities and relieving pain. Suitable for tooth decay pain.

3. Use 10 leek roots, 20 Sichuan peppers, and a little sesame oil, which are pounded like mud, and apply them to the side of the diseased teeth and cheeks. It is said that "it can be cured in a few times". Suitable for tooth decay pain.
