| I used an iron supplement with my baby as he was anemic, It does stain the teeth grey, but it is only superficial, the tooth itself underneath will still be white. The dentist said it would very easily come of with a dental cleaning once he was old enough to have that. He had iron drops for about a year and didn't have his teeth cleaned until age three, but honestly after he stopped the iron with time the grey wore off before he had his teeth cleaned. |
