ELI5: Why does the acid in coca-cola cause tooth cavities, but the acid in oranges is fine?
gpt
It's not fine. Orange juice is just as harmful, if not more, than soft drinks / sodas.  If you eat an Orange however you are getting alot of fibre (the pulp) along with the juice. The chewing produces saliva which will help neutralize the harmful acids in your mouth.
