hi my 5 year old sons bottom lip has become very dry and chapped, when he woke up this morning there was a yellowish crust on it which i wiped away with water and cotton wool, he is also complaining of pain on his top teeth when brushing, despite being at the dentist a week ago and everything being fine.
