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.
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.
Experiment 1: The adolescents in 14- 19 were investigated by questionnaire, and dentists were invited to judge the tooth corrosion and wear of these adolescents.
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.
Experiment 2: Soak teeth in different drinks for two weeks to study different degrees of acid erosion.
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? 2; The degree of dissolution, and the teeth soaked by Diet Coke dissolved even more than Coca Cola in the same time, 3mg/cm? 2; .
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? 2; .
I personally think it's a carbonated drink, so I sent you this message, hoping it will help.
