Why tooth decay?
Many studies show that there are 3 factors that cause tooth decay: bacteria, sugars and the time that bacteria and sugars stick to teeth.



The bacteria that cause tooth decay take shelter in the dental plaque layer. Sugar in food. Time bacteria exist in the mouth from 20 minutes - 1 hour after eating. Bacteria use sugars to form dental plaque, which ferment sugars to create acid, which erodes inorganic substances in enamel and dentin causing tooth decay.
Teeth are also corroded by the acid environment in the mouth, this process is absent of bacteria. This is the process of losing hard tissue of teeth (enamel, dentin) progressively irreversibly. Hard tissue of teeth is chemically eroded from the tooth surface due to the acids present in the mouth
The acids in foods include citric, phospholic, ascorbic, malic, tartaric and carbonic acids, which are abundant in ripe fruits and fruit juices, vinegar and carbonated drinks.



Many studies show that: People who regularly drink fruit juice, fizzy drinks, eat pickles, tomato tomatoes, sour fruits such as star fruit, citrus, smoothies, tamarind, tamarind ... have eroded teeth increasingly heavy.
What food can cause tooth decay?
The common sugar (saccarose) causes the most decay, followed by glucose, fructose and maltose. These sugars are found in table sugar, confectionery, honey, molasses, ripe fruit, sugarcane, jaggery, soft drinks, etc. The sugar in food and drink is stuck in the mouth, creating conditions for bacteria to ferment. .




For starch in foods such as rice, corn, potatoes, cassava, beans: many studies show that they cause less tooth decay. Therefore, people who eat more starch, eat less sugars have lower levels of tooth decay. On the contrary, those who eat less starch but eat more sugar have more cavities. Raw carbs cause less tooth decay, more starch and saccarose mixes cause more cavities.
Children's medicines such as antibiotics, vitamins, cough syrups, etc. contain large amounts of sugar, so they can speed up tooth decay. Children also have tooth decay caused by bottle-feeding: the habit of some breastfeeding families at bedtime, to bed with bottles until they sleep; Many mothers are too spoiled for their babies or let their babies suck their bottles during sleep to deal with babies being fussy at night.
How to eat to prevent tooth decay?
To prevent tooth decay, we should eat and drink according to the following recommendations: just eating sugar less than 500g / person / month will significantly reduce the risk of tooth decay.



Sweeteners that replace sugars and xylitol do not cause tooth decay. The less sweet kind is transformed by bacteria in the mouth, but at a very slow speed, it can be considered safe. In the future, children's medicine also uses sweeteners to replace sugar, which will reduce the incidence of tooth decay in children.
Foods rich in calcium, vitamin D in milk, green vegetables, fish, cheese ... help to prevent tooth erosion, tooth loss and osteoporosis in the elderly. Cheese is rich in calcium, when eating calcium, the cheese attaches to the surface of the teeth, which effectively restores the tooth surface against acid attack.



The problem is to propagate to our people have a habit of eating cheese.
Vegetables that are not harmful to teeth include: green vegetables, cucumbers, cauliflower, zucchini, pumpkin, eggplant, radish, carrots, melon, melon ... help clean teeth and remove plaque. cling. Eat 200g / meal and eat regularly every day. However, there are vegetables that are harmful to teeth such as bananas, dates, grapes, tomatoes, peas, figs, sweet apples, pomegranates, oranges, tangerines, kumquats, tamarind tamarinds, crocodiles, and umbrellas, etc.



More carbohydrates or acids corrode teeth.
Therefore, we should alternately use vegetables that cause tooth decay and those that do not cause tooth decay, ensuring both nutrients and preventing tooth decay. To minimize the erosion process, it is necessary to limit the number and frequency of drinking carbonated water.
Maintain oral hygiene
Should gargle immediately after eating or drinking sweets. Brush your teeth 2-3 times a day, preferably in the morning when you wake up, after meals and before bed. Use fluoride toothpaste. Note that you should not brush your teeth immediately after eating and drinking juice, because then the enamel layer is softer due to the effect of fruit organic acids, the toothbrush will erode tooth enamel.
Wait about 30 minutes to allow time for saliva to recover and balance the minerals of the teeth, then brush your teeth.



Children should not drink juice with a bottle because it will prolong the time your baby's teeth are exposed to sugar and acids from fruits. Children should not eat more sweets.
