First of all, carbonated beverages are not good for teeth. The acidic stimulation itself can cause damage to teeth, and long-term consumption of carbonated beverages may cause acidic erosion of the whole mouth, which may cause damage to the whole mouth and even loss of teeth. Secondly, if a patient occasionally drinks carbonated beverages and has acidic teeth, it means that the patient has signs of dentin sensitivity. In this case, the patient can apply anti-allergic toothpaste to improve the anti-sensitivity properties of the teeth as appropriate. If it still does not improve, the patient can go to a professional dentist to check if there is any decay or defect in the dentin, which causes the acidity of the tooth when it enters the acid, and make the treatment accordingly. In most cases, after desensitization treatment, the teeth will be more acid-resistant and less acidic when drinking drinks.
