How much harm does carbonated drinks do to teeth?

Acid etching is a disease in which teeth are mainly eroded by acidic substances without bacteria, which leads to the chronic destruction of demineralization of hard tissues of teeth, affects aesthetics and normal social interaction, and also affects the function and quality of life of teeth. Most patients with acid corrosion have the same habit: they like carbonated drinks such as cola.

Many people know that sweets do great harm to teeth, but little is known about the harm of carbonated drinks to teeth. Carbonated drinks contain a lot of acidic substances, which will keep the mouth acidic for a long time and have demineralization effect on teeth. However, carbonated drinks such as Coke, Sprite and Fanta have penetrated into our daily life, and many teenagers use them as daily drinking water.

Although carbonated drinks are extremely weak in acidity, if they are drunk for a long time, the intake is large and the frequency is high, and if they are not protected, they will also cause cumulative erosion, especially the calcification degree of deciduous teeth and permanent teeth in childhood is low, which is easy to suffer from this disease. Carbonated drinks contain a lot of sugar, which is used by bacteria in the mouth to produce acidic substances, which can cause or accelerate dental caries.

Dental caries caused by drinking carbonated drinks for a long time. The clinical manifestation of acid erosion is often that the hard tissue of teeth has no obvious thin-walled tissue loss at first, only teeth are sensitive to cold, heat, acid and sweet stimuli, and thin-walled tissue loss gradually occurs over a long period of time.

The researchers did the following two experiments to prove the erosion of teeth by carbonated drinks.

A questionnaire survey was conducted on the intake of fruit juice, sports drinks, sweet carbonated drinks and other foods among teenagers aged 14 ~ 19, and dentists were invited to judge the tooth corrosion and wear of these teenagers.

The results showed that the probability of dental erosion in adolescents was as high as 3 1.7%, and the most serious dental erosion was in carbonated beverage group. You know, tooth decay is usually considered as an important risk factor to reduce a person's tooth whiteness and health.

The teeth were soaked in different drinks for two weeks to study the different degrees of corrosion.

The results showed that there was no significant difference in the degree of tooth corrosion between ordinary sugary soda and sugarless soda. In the experiment, the enamel of the teeth soaked in Coca-Cola group was 2.8mg/cm? The degree of dissolution, and the teeth soaked by Diet Coke dissolved even more than Coca Cola in the same time, 3mg/cm? . After soaking in orange juice, the hardness of enamel decreased by 84%, and the roughness was obviously improved. Lemon and lime juice corrode teeth as much as battery acid.

However, not all drinks are "friendly" to teeth. In most daily drinks, mineral water and beer have the least influence on teeth, followed by red tea and coffee. The degree of tooth corrosion soaked in these drinks is less than 0.4mg/cm? .

In addition, milk is also a relatively safe drink, because it helps to restore the neutral pH value of saliva.
