My daughter just turned 16 and has what appears to be “white stains on her teeth. I thought it was from her braces but the orthodontist said it was probably from the iron she had to take when she was an infant.
She was anemic when she was a baby; at 2 months of age we put the iron drops down the side of her check once a day for 6 months. We did this until she stopped breastfeeding and got the iron from her formula.
Either way, now that she has straight teeth, she wishes they were a nicer color.

What are her options?
