Dark Iron Stains on Baby Teeth.
If a child has dark stains on their baby teeth, it may be due to the iron in the multivitamins. Though rare, for a child that is susceptible to this type of stain, the parents need to be vigilant about brushing regularly and thoroughly in order to stay on top of it. Once these types of stains have taken root, they’re very difficult to get off, even with a professional scrubbing from a dentist.
However, this type of stain will not affect the health of the child’s teeth though the teeth will not look good. It is advised to see a dentist to confirm the reason for any tooth discolorations and to receive a treatment plan if needed.
