Why do you have tooth decay when you eat too much sugar?

We know that the "enamel" on the tooth surface is extremely hard, but something can corrode it and make it disintegrate, and that is "acid". So where do these acids come from? Bacteria! (Note that it is not a bug! )。 However, it is difficult for a clever woman to cook without rice. Bacteria need food and grass to produce acid. This food and grass is sugar. Eating sugar is equivalent to feeding bacteria, which will inevitably cause harm to teeth. (Among all sugars, the strongest acid-producing effect is sucrose, glucose, maltose, fructose and so on. )

These bacteria form "dental plaque" on the tooth surface, and under the continuous supply of "sugar", they produce acid. However, dental plaque has strong adhesion and is not easy to be washed away by "saliva", so it can form "local strong acid area" on the tooth surface unscrupulously, and then the tooth slowly disintegrates under the action of acid to form tooth decay.

a good way to make teeth and candy really good friends is "candy day once a week". Rinsing your mouth in time after eating sugar or brushing your teeth with fluoride toothpaste can also effectively prevent the harm of sugar to children's teeth.
