The hot summer days are here, many people, especially teenagers, are fond of carbonated drinks, a bottle of frozen carbonated drinks will bring a burst of cool, however, this temporary refreshment, but brings potential harm to dental health. I once saw a parent bring her child to the clinic, she said, “My child brushes his teeth every day on time, usually pay attention to oral hygiene, but I do not know why there is a lot of white plaque on the neck of the teeth, and the teeth seem to have become brittle, and some of the tooth surface are lost.” The oral surgeon saw the young man, and after careful clinical examination and detailed questioning, finally found the cause of the disease. It turned out that the young man never drank plain water in the summer, but always quenched his thirst with carbonated beverages, and long-term consumption of carbonated beverages had eroded the young man’s teeth. The carbonated drinks we often drink contain a lot of acidic ingredients and sugar, and when we drink them, our teeth are soaked and acid-etched by the acid, the minerals on the surface of the teeth are dissolved, the enamel on the surface of the teeth becomes thinner, and the teeth become weak and sensitive. The sugar contained in the beverage also increases the chance of tooth decay in teenagers. The long-term accumulation of carbonated beverages will cause the formation of demineralized white spots on the tooth surface, acid erosion and even the loss of tooth enamel because the permanent teeth have not erupted in the mouth for a long time and the mineralization development of the teeth has not yet been completed. Therefore, the young man mentioned earlier had a lot of white spots on the neck of his teeth due to the loss of minerals. The enamel on the neck of the teeth is very thin, so the symptoms appear first on the neck of the teeth. After hearing the doctor’s explanation, the young man immediately woke up and said that he would not drink carbonated drinks anymore. So what can be done to treat teeth that have been demineralized? The doctor told the mother that she could use artificial mineral colloid or liquid coating locally to promote remineralization of the tooth surface, and that she could have dental checkups every once in a while and use fluoride to promote tooth mineralization and prevent caries. After a few weeks of treatment, the young man’s teeth finally regained their normal luster and appearance.
