Frequency beats quantity
Each sugar or acid exposure drops mouth pH for about 20 minutes. A candy bar eaten in five minutes is one exposure. A soda sipped over three hours is dozens.
The surprising offenders
Sparkling water is acidic even without sugar, especially citrus flavored. Dried fruit sticks in grooves for hours. Sports and energy drinks combine acid and sugar. Sugar-free gum, by contrast, protects teeth by stimulating saliva.
Practical adjustments
Drink acidic beverages with a meal rather than sipping all afternoon, follow with plain water, use a straw for iced coffee and soda, and finish meals with cheese or nuts to buffer acid.
Key takeaways
- •Constant sipping is the real problem.
- •Rinse with water after anything acidic.
- •Xylitol gum after lunch is a genuinely useful habit.
