The extreme acid present in these beverages has a very strong corrosive effect on the teeth’s surface, giving them a decayed look and thus the creation of dental caries. Hence, it is necessary to highlight the adverse effects of the above products as they can be a probable source of damage to the enamel layer of the teeth. Water or milk are some of the safest drinks and should always be recommended, even when parents and schools still consider these drinks to be the most harmful ones if a person is thirsty.
