BEST DENTIST IN AMINJIKARAI! Simply put, drinks with a low pH can have a demineralising effect on your tooth enamel. Tooth enamel is the hardest substance in our body, but it can’t stand up to being repeatedly immersed in a bath of highly acidic sugar water. Not only can you lose the protective enamel coating on your teeth, the sugar used to sweeten most energy drinks creates the perfect storm for tooth decay. But the pH story continues.
