So what is the most lethal effect on the teeth? Some people say: don't brush your teeth! Some people say: Open the cap with your teeth! Others said: smoking and drinking!
In fact, why is the tooth one of the hardest tissues in the human body? Because it is covered with a layer of enamel, the thickness of enamel on each tooth surface is different, the normal thickness is about 2 ~ 2.5mm, 95% of its constituent materials are inorganic, and the main component is hydroxyapatite. Its hardness is as high as 7-8 degrees (the hardness of the diamond is 10). It can be said that it is slightly inferior to the hardness of the diamond, but it is almost the same as the hardness of the crystal. However, the strong appearance of the goose will also have this fragile side. When hydroxyapatite, the main component of dental enamel, is exposed to an acidic environment, the "calcium" and "phosphorus" in it will be released in ionic form, which is often referred to as tooth demineralization.
But I want to tell you today that all of these are not terrific. The most harmful to teeth is often these very common foods:
The Blacklist of Destroying Food is as follows
Betel nut-Chewing betel nut, in addition to blackening, abrading and loosening teeth, causing gum atrophy, can also cause periodontal diseases such as oral submucosal fibrosis and oral mucosal leukoplakia. According to a survey, 88% of oral cancer patients have the habit of eating betel nut.
Coffee-Although it contains more antioxidants, it can easily cause tooth stains, and plaque has a lot to do with it.
Canned luncheon meat-looks low in calories and tastes good. In fact, it contains a lot of starch. Starch will break down into sugar, so it is an acidic food and will damage your teeth.
Peanut butter-its "stickiness" can easily cause food impaction and induce dental caries.
Preserved fruits-As we all know, pickled or dried foods contain very little water, so the sugar is very saturated, and it is easy to cause dental caries.
Soda water—The pH value of most carbonated beverages is between 2.2 and 4.9, and the critical pH value of enamel dissolution on the tooth surface is 5.5. If the beverage does not leave the mouth, it is equivalent to soaking the teeth in acidic liquid. In the most extreme state "Acidosis" can even destroy a child's entire mouth.
Speaking of this carbonated beverage, as a parent, you have to pay attention! Because children's teeth are not completely calcified, they are more susceptible to acid attack. Not to mention that children often do not have the correct brushing skills.
Therefore, today, Xiaobian, on behalf of all the medical staff of the vast oral cavity, reminded parents that children must drink less beverages, especially soda, otherwise children's teeth once there is a problem, affecting future oral health! If your child's teeth are already caries, we should treat them as soon as possible.
