There are many reasons as to why the teeth are erupting slow Sincere advice to visit dentist soon to avoid future complications Thank you

This generally happens if the milk tooth hasn't exfoliated and is blocking the path...in this case the milk tooth will need to be extracted. Sometimes however the eruption is slow because of extremely dense gums or the adequate amount of root formation hasn't happened for the underlying tooth to erupt. Visit a dentist for a check up.

If milk teeth is blocking the way of coming tooth that need to be removed but only after checking in the x-ray we will come to know the real reason
