this didn't really go under any category in the forums. I just moved to college and have noticed a slight increase in chalky white patches on my front teeth. Before they were hardly noticeable and now they're slightly more noticeable. From the symptoms, I'm thinking flourosis. I've heard that it can only form before permanent teeth are formed but haven't seen a clear answer. I was thinking that the water at college has more flouride than usual? I've only been here a month though. So the questions are: could flourosis work that fast? can you get flourosis discoloration after permanent teeth are in? is there a way to cover it up? I'm not swallowing toothpaste, but I do have to drink the water since it's the only thing around. I could buy bottled water but I want to make sure it will help before I doll out the cash.
