In their study, researchers also found that both sugary and sugar-free drinks— including flavored mineral water— cause a measurable loss of tooth enamel, with no significant difference between the two types of drinks. Six of eight of the sports drinks tested caused dental enamel loss.
Researchers suggested the following to protect teeth health:
- Look for acidic additives such as citric acid and phosphoric acid in the ingredient list of sugar-free products.
- After eating or drinking acidic products, rinse your mouth with water and wait for an hour before brushing. Doing so any sooner can remove the softened tooth layer.
- Chew sugarless gum after drinking acidic beverages— such as soda— on its own to increase saliva flow to neutralize the acid.
