Four types of foods that are very effective in preventing tooth decay

Tooth decay has always been a very common oral disease in life, and various poor eating habits and lifestyle habits are common causes of tooth decay. So what should be eaten to 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. Foods to prevent tooth decayGreen tea Developing the habit of drinking green tea regularly is also very important for human health, and a large number of studies have found that green tea contains a lot of fluoride. This substance can be combined with apatite in the teeth, which acts as a good protection against tooth decay. Green tea also contains a lot of catechins, which reduce the number of streptococcus mutans that cause tooth decay in the mouth, while also refreshing breath. BananasBananas, which are very common in daily life, also have a good anti-disease and protective effect on the human mouth, that is, bananas can help us eliminate plaque and prevent tooth decay. This is due to the abundance of vitamin C in bananas, which is why this tropical fruit protects oral health. Vitamin C is very important for the human body, and if it is deficient for a long time, it can lead to fragile gums. In this case, it is easy to suffer from oral diseases, and there are also symptoms such as swollen gums, bleeding, loose or lost teeth, and it can also cause tooth decay which can be harmful to human health. There are many ways to prevent tooth decay on onions, and eating more onions in daily life also has a good prevention and control effect, and eating more onions can also effectively improve the antibacterial ability of the oral cavity, so as to protect the health of the entire oral cavity. The reason why onions have an antibacterial effect is due to the fact that they contain a lot of rich sulfur compounds, which are a powerful antibacterial ingredient that can kill deformations including causing our tooth decay, but many people in life do not like to eat onions, which is a very bad diet. CeleryEating more celery in daily life can help us effectively ensure oral hygiene, thus playing a role in preventing tooth decay. Celery is an extremely common vegetable on our table, so why does it have the effect of protecting teeth? This is due to the fact that celery is rich in crude fiber, which acts like a broom to remove some of the food debris from the teeth, and the harder you chew, the more bacteria can be removed from the surface of the teeth. Precautions for Diet to Prevent Tooth Decay 1, Carbohydrates in Food Carbohydrates in food will provide heat and nutrients to bacteria in the mouth after fermentation, 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 content of fluoride is well known, and fluoride is the most effective nutrient to prevent 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, so that brown spots appear on the teeth, which can not be removed permanently, which is very unsightly!3. The acidity of the food itselfThe acidity of some food itself can directly dissolve the 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!4. The amount of saliva that food stimulates saliva secretion contains a lot of water, which can rinse the food and bacteria left on the tooth surface, and can be used as a buffer to neutralize the acid produced by some 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 is sticky to the teeth, which will continue to provide raw materials for bacteria to make acid, and increase the time for enamel erosion. 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!
