Scientists have revealed what sugary soda does to teeth.

Recently, there have been several recent developments in the field of international medical health, and the industry and the public continue to be concerned about these developments. According to a preliminary comparison of the effects of several popular beverages on oral pH, drinking water may have a better effect on tooth acidity than sugar-sweetened water. Many people are moving from soda to sugar-sweetened bubble water, and our findings suggest that unsweetened bubble water may be a lower-risk alternative to soda when consumed with moderate intake and accompanied by good oral hygiene habits, according to Dr Wajiha Zulfiqar, a Ph.

D. in Nutritional Sciences at Purdue University. Zulfiqar presented the results at the flagship annual meeting of NUTRITION 2026 for the year 2026.

The annual meeting was held from July 25 to 28, 2026, at the National Harbor near Washington, D. C. , just outside the Maryland National Port.

The purpose of the study was to investigate that the researchers tested sugar-sweetened water, ordinary foam water, hydrogen-strengthened foam water and ordinary water in 20 adult men. Each of the participants drank each drink, allowing the team to reduce the effects of natural differences between individuals. The researchers measured the pH of the saliva rather than relying on the acidity of the drink itself.

Through the same experimental framework, we directly compared the effects of different beverages, and evaluated the effects of sugar-containing soda (as opposed to plain water) and pure water as a neutral reference. Sugar caused the greatest decrease in pH in the beverage tested, with sugar producing the greatest increase in oral acidity. The saliva pH significantly decreased 2 minutes and 20 minutes after drinking.

Within 2 minutes, unsweetened or unsweetened soda water caused a brief decrease in the saliva pH within 2 minutes after drinking. Within 5 minutes, calcium-strengthened soda water caused a significant decrease in the saliva pH within 20 minutes after drinking.
