White spot on 9mth old's new tooth

[Hulla]

My dd has just got one of her top front teeth and as its coming down it appears to have a white spot on it.

Does anyone know what this is?

Many thanks

I thought I would google flourosis (which is what the white spots are called) and antiobiotics as dd was given these in hospital when she was born. I found this article which explains it.

I hope it doesn't affect her adult teeth too. I wonder if I should see a dentist for her?
