Sparkling Water Lowered Mouth pH Less Than Soda
A 20-person crossover test found brief acidity changes that stayed above the enamel-dissolving threshold.
Summary
A 20-person crossover test found brief acidity changes that stayed above the enamel-dissolving threshold.
Participants drank soda, plain sparkling water, calcium-fortified sparkling water and still water while researchers tracked salivary pH. Soda produced the strongest and longest acidity; both sparkling waters returned near baseline by 20 minutes. The conference result measured short-term chemistry, not long-term enamel damage.
Why it matters
