What causes enamel discoloration or damage?

[LaurieG]

I know damage can be present in celiac, but why?  Is there a particular enzyme or nutrient that would cause damage if it were not present in high enough quantities?

[Panserbjorne]

it's malabsorption caused by the damage to the intestinal villi.  Celiac disease, if gluten is not avoided, can disrupt the absorption of any nutrient which can affect the body in a number of ways.  Teeth are not exempt.

So true for me as my enamel is really bad. It has been for years. I am just trying to heal it after figuring things out. After cutting out gluten for my dd and giving her cell salts, her teeth are really looking solid and white again.
