Why the Coca-Cola is corrosive?

The pH of Coca-Cola is around 2.5, similar to the pH of lemon juice. This level of acidity is enough to dissolve tooth enamel, the outer layer of your teeth that protects them from damage. When you drink Coca-Cola, the acid in the drink attacks the calcium and phosphate in tooth enamel, causing it to dissolve. Over time, this can lead to cavities, tooth decay, and other dental problems.

In addition to carbonated soft drinks, other acidic beverages such as fruit juice, energy drinks, and sports drinks can also damage tooth enamel. To help protect your teeth from the damaging effects of acid, it is important to limit your consumption of these beverages and brush your teeth twice a day with a fluoride toothpaste.
