I am not sure what the cause of my problem is, but I am hoping to find out here. My enamel (I think) seems to be getting worse and worse. When running my tongue over my teeth, it feels like my teeth are quite sharp on the top (edges) of the teeth. My roots are good, don't have cavities either from this. Can this be some kind of disease? Lacking something in my diet? Is there something that can be done to protect my teeth from further deterioration? I drink mostly water for the last few years, so I am guessing it it not from what I drink. When I was younger I ate lots of candy and drank lots of Coke, and I did not have this problem then. It just seems to be getting progressively worse over the last few years. I am 34 if that helps. Looking for answers.
