Well....it could be natural, as baby teeth are often streaky white. But.....it could also be the beginning of demineralization.
I would think about having a dentist check it out just so that you can be sure. If it is demineralization, then it can be reversed now with tiny bits of flouride. If it is demineralization and you do nothing, it can progress rapidly. If it is natural, then no worries
The advice I have come across (to late for my dd
) is that if something seems abnormal, see a dentist. She is not too young!
