Hello! Just wondering, what would be considered long-term? I've be using everyday for the last 7months, at first it was almost 4-5 grams a day, now (within the last month) it's slowed to maybe a half gram in the morning, trying to be clean for a bit. Just wondering, when does erosion of the cavities usually occur? Is it a, "it varies from person to person," thing? Or are the scenarios I've read about with people that have bad erosion in the roof of the mouth, have 5 years of daily use. Can't really find a straight answer, want to see if anyone has any input. I am soo sorry if this isn't the place to post something like this, will delete if people don't like it here.
