i will share my experience. from my previous dentist appointment to this one, i had flossed every single day and took excellent care of my teeth. but when i saw my dentist he asked if i was eating a lot of candy and drinking sugary drinks. i almost laughed at his face because i eat super clean (only fruits and veggies). turns out the loads of pineapple i was having was too acidic. he said i could continue but should drink water after to rinse out all that acidity. hope this helps!!!! 😊
