Thanks Anne and Al,

The article is great, I sent it to my Dad already.

The picture is worth a thousand words...I will get my dentist to look at this . My sisters kids teeth looked like this but 10xs worse and it was their baby teeth. I am sure they both have this because she is the double DQ2 and her husbands sister has Celiac and he has always had very long bathrooom visits.

But, I still wonder what else we should look for or is it only enamel problems?
