Scientists Investigate Impact of Sparkling Water on Dental Health
Recent research presented at the NUTRITION 2026 meeting by Wajiha Zulfiqar from Purdue University suggests that unsweetened sparkling water may be a safer alternative to sugar-sweetened sodas concerning dental health. The study compared the effects of various beverages on oral acidity, finding that while sparkling water can lower oral pH, its impact is less severe than that of soda. The research involved testing sugar-sweetened soda, regular sparkling water, calcium-fortified sparkling water, and plain water in 20 adults, measuring salivary pH to assess the immediate effects on oral acidity.
