While many people believe that sugar-free beverages do not pose a danger to teeth, the fact is sugar-free drinks and confections can be as damaging as their sugary counterparts. It is important to know that, whether or not a drink contains sugar, it is the acid in those drinks that does the damage. Sugar is linked with tooth decay because it creates plaque on the tooth enamel that bacteria digest and convert to acid, which etches away at enamel to cause decay. With this in mind, even with the sugar removed, drinks containing acid will also erode tooth enamel. According to a recent study, the majority of soft drinks and sports drinks cause measurable loss of tooth enamel.
