Enamel problems (I have horizontal grooving in my teeth ... they grew in that way) are what triggered me to get tested for gluten intolerance after many years of various health problems that doctors couldn't diagnose. It turns out I am gluten intolerant, likely celiac. Definitely, get checked for gluten intolerance and celiac disease if you have similar dental problems. The dental problems are a sign of severe malnutrition during early childhood when the teeth are first developing, usually only seen in third-world countries; if seen in industrialized countries it is most likely celiac disease. I know I was fed well as a child (lots of healthy food available, and I was a big eater), so this clued me in that celiac was a high likelihood. I just wish dentists knew that back when I was a child so I didn't have to wait so many years to discover what was causing my health problems. I'm 45 now, and only discovered the gluten intolerance two years ago.
