Soda is unquestionably acidic:
- Water has a pH level of 7, (which is meant to be human's primary source of fluid intake);
- Soda has a pH of approximate 2.5; and
- Diet soda fares only slightly better at around 3.2.
These acidity levels are close to that of vinegar; no wonder they can rot your teeth! {relatedarticles}
To be fair, it's important to note that none of the subjects in the AGD's study practiced good dental hygiene, nor did they visit the dentist regularly. These issues undoubtedly contributed to their tooth decay.
It goes without saying that if someone drinks several liters of soda a day (as many who have a soda addiction do), their teeth will probably be the least of their worries; greater health concerns are at stake.
